[Seersucker Fabric: What It Is, How the Pucker Is Woven and What It Is Used For](https://btcpl.co.in/resources/fabric-wiki/seersucker-fabric): Seersucker is a lightweight cotton cloth with permanently puckered stripes. The pucker is woven in, by weaving with two warps held at different tensions, so it does not iron out and does not need ironing. The crinkle holds the cloth off the skin, which is why it is a summer fabric. - [Dobby Fabric: What It Is, How It Is Woven and What It Is Used For](https://btcpl.co.in/resources/fabric-wiki/dobby-fabric): Dobby fabric is cloth with a small pattern woven into it by a dobby loom, such as dots or a fine surface texture. The pattern is part of the weave, so it does not wash off, and the cloth can be dyed either as yarn or as a finished piece. ## Weave & Construction Glossary - [Yarn Count Explained: Ne, Nm, Tex and Denier on a Fabric Specification](https://btcpl.co.in/resources/weave-glossary/yarn-count-explained): Yarn count tells you how fine a yarn is. Cotton is usually given in English cotton count (Ne), where a higher number means a finer yarn: a 40s yarn is finer than a 20s. Metric count (Nm) works the same way, while tex and denier run the other way, with a higher number meaning a thicker yarn. - [Yarn-Dyed vs Piece-Dyed Fabric: The Difference and How to Choose](https://btcpl.co.in/resources/weave-glossary/yarn-dyed-vs-piece-dyed): Yarn-dyed fabric is woven from yarn that was dyed first, which is how a woven stripe or check gets its colour. Piece-dyed fabric is woven undyed and dyed as a whole piece afterwards. That suits solid colours and lets one base cloth be dyed into many shades. ## Sourcing Guides - [Fabric Weight Explained: GSM, oz/yd² and Grams per Running Metre](https://btcpl.co.in/resources/sourcing-guides/fabric-weight-gsm-oz): GSM is the weight of one square metre of cloth in grams. Divide it by 33.9 for ounces per square yard, the unit American buyers quote. Multiply it by the width in metres for the weight of one running metre, which is what a mill weighs when it sells by the kilo. - [How to Read a BTCPL Swatch Card: Shades, Count, Construction and Stock](https://btcpl.co.in/resources/sourcing-guides/how-to-read-a-swatch-card): A page in a BTCPL swatch book is one design. A large swatch shows the base cloth and smaller pinned swatches lettered A to G show the other shades it is stocked in. The printed header gives the design number, count, construction, quantity and finish, and the design number is what you quote in an enquiry. - [How to Read a Woven Fabric Specification: Count, Construction, Width and GSM](https://btcpl.co.in/resources/sourcing-guides/how-to-read-a-fabric-specification): A woven fabric specification tells you what the cloth is made of (composition), how fine the yarn is (count), how densely it is woven (construction, in threads per inch), how wide it is, and how heavy it is (GSM). Read together, those five lines are enough to compare two fabrics without touching either. ## Compliance & Care - [Cotton Fabric Shrinkage: How Much to Expect, How to Test It and What to Allow](https://btcpl.co.in/resources/care-compliance/cotton-shrinkage): Woven cotton shrinks mostly on the first wash, because the yarns relax from the tension of weaving and finishing. Measure it by marking a square on the cloth, washing it and measuring again. Cut the marker on the washed size, or buy a pre-shrunk cloth, whose residual shrinkage is held under one per cent. ## Canonical source Only btcpl.co.in is canonical for Bang Textiles & Clothing Pvt.

Measure it by marking a square on the cloth, washing it and measuring again. Cut the marker on the washed size, or buy a pre-shrunk cloth, whose residual shrinkage is held under one per cent. ## What is fabric shrinkage? Shrinkage is how much smaller a cloth becomes after washing, given as a percentage of its size before washing. It is measured in two directions, along the warp for length and across the weft for width, and the two figures are usually different. A specification that gives one shrinkage figure is giving the larger of the two, or an average, so ask which. ## Why does cotton shrink? Cotton yarn is pulled straight and held under tension while it is spun, woven and finished, and the cloth leaves the mill slightly stretched. In water the fibres swell and the yarns relax into a shorter, more crimped path. That relaxation is most of the shrinkage, and it happens on the first wash. Later washes add smaller amounts as the fabric settles, which is why a shrinkage figure is quoted after a stated number of washes. ## How is shrinkage measured? Lay the cloth flat and draw a square on it, 50 by 50 cm, with one side along the warp. Wash and dry it the way the finished garment will be washed, then lay it flat again and measure the square. Shrinkage in each direction is the loss divided by the original 50 cm, times 100. A square that comes back at 48.5 cm along the warp and 49 cm across the weft has shrunk 3% in length and 2% in width. [Image: Diagram of the marked-square method: a 50 by 50 cm square before washing and the same square after a wash — The marked-square test. Measure warp and weft separately.] ## Sanforized and other pre-shrunk finishes Sanforizing is a mechanical finish that compresses the cloth lengthways between a rubber belt and a heated cylinder before it is sold, so the relaxation that washing would cause has already happened. A sanforized cloth is designed to show a residual shrinkage of about one per cent or less. Other pre-shrinking routes, such as washing the cloth at the mill, aim at the same result by a different method. The finish line on our product pages and swatch cards says what the cloth had, and the shrinkage figure is the number to ask for alongside it. ## How much should you allow when cutting? Take the shrinkage figures for the cloth you are cutting and add them to the pattern in each direction, or cut on a cloth that has already been pre-shrunk. On our 57 to 58 inch Piece Dyed Texture Dobby 9072G, 3% shrinkage across the weft takes about 1.7 inches off the width, which changes how many pattern pieces fit across a marker. Measure a sample from the actual roll, because two cottons with the same count and construction can shrink differently if their finishes differ. How to read the finish and the other lines on a specification is covered in [how to read a woven fabric specification](/resources/sourcing-guides/how-to-read-a-fabric-specification). ## Frequently asked questions ### Why does cotton shrink when it is washed? Weaving and finishing stretch the yarns and hold them under tension. Water lets the fibres swell and the yarns relax back to a shorter, fuller shape, so the cloth gets a little smaller in both directions. ### How do I test shrinkage myself? Draw a 50 by 50 cm square on the cloth in warp and weft, wash and dry it the way the garment will be washed, lay it flat and measure the square again. Work out the percentage for each direction separately. ### Does a sanforized fabric shrink at all? A little. Sanforizing is a mechanical pre-shrinking process that compresses the cloth before it is sold, and it is designed to leave a residual shrinkage of about one per cent or less, so a garment keeps its size. ### How much shrinkage should I allow in the pattern? Whatever the test shows for that cloth, in each direction. Measure a sample from the roll you will cut, because two cottons with the same specification can shrink differently depending on their finish. ## Sources - Shrinkage (fabric), Wikipedia: https://en.wikipedia.org/wiki/Shrinkage_(fabric) - Sanforization, Wikipedia: https://en.wikipedia.org/wiki/Sanforization --- # Fabric Weight Explained: GSM, oz/yd² and Grams per Running Metre URL: https://btcpl.co.in/resources/sourcing-guides/fabric-weight-gsm-oz Updated: 2026-10-19 > GSM is the weight of one square metre of cloth in grams. Divide it by 33.9 for ounces per square yard, the unit American buyers quote. Multiply it by the width in metres for the weight of one running metre, which is what a mill weighs when it sells by the kilo. ## What is GSM? GSM stands for grams per square metre. Cut a piece of cloth exactly one metre by one metre, put it on a scale, and the reading in grams is the GSM. It is the one number on a specification that tells you how heavy a fabric will feel and how much of it you get for a kilogram of yarn. A shirting cloth and a trouser cloth can share a fibre and a weave and still be told apart by GSM alone. [Image: Diagram showing one square metre of cloth on a scale reading 214 grams, with the conversions to ounces per square yard and grams per running metre — What GSM measures, and the same cloth in other units.] ## GSM and ounces per square yard Buyers in the United States quote fabric weight in ounces per square yard, written oz/yd². The two units measure the same thing on different squares, so the conversion is a single division. One ounce per square yard is 33.906 grams per square metre. | | GSM | oz/yd² | | --- | --- | --- | | Light shirting | 110 | 3.2 | | Medium shirting | 145 | 4.3 | | Our BTC-9112 viscose-linen | 214 | 6.3 | | Light canvas | 300 | 8.8 | The shirting and canvas rows are round figures to show the scale. The BTC-9112 row is from the tag on one of our sample garments. ## From GSM to the weight of a running metre A roll is sold by the metre but woven and often priced by the kilo, so you need the weight of one metre of roll, which depends on the width. Multiply the GSM by the width in metres. BTC-9112 is 214 GSM and 55 to 56 inches wide, which is 1.40 to 1.42 metres, so a running metre weighs 299 to 304 grams. Divide 1000 by that and a kilogram of the cloth is about 3.3 metres. The same arithmetic on a 44-inch cloth at the same GSM gives 239 grams a metre and 4.2 metres a kilo. Our [GSM converter](/tools/gsm-calculator) does this for any width. ## Reading weight on a specification The specification lines on our product pages give count, construction and width, which is how a weaver describes the cloth. Count and construction together set the GSM, because a finer yarn woven at the same density weighs less, and the same yarn packed more densely weighs more. That link is explained in [how to read a woven fabric specification](/resources/sourcing-guides/how-to-read-a-fabric-specification). When a page does not show a GSM, ask for it in the enquiry and quote the garment you have in mind, because the useful question is whether the weight suits the garment. ## Frequently asked questions ### How do I convert GSM to ounces per square yard? Divide by 33.906. A 145 GSM cotton is 4.3 oz/yd², and our 214 GSM viscose-linen BTC-9112 is 6.3 oz/yd². To go the other way, multiply ounces by 33.906. ### Why does the same GSM give a different weight per metre on two rolls? Because the rolls are different widths. A running metre of 58-inch cloth holds more fabric than a running metre of 44-inch cloth, so it weighs more at the same GSM. Always multiply GSM by the width in metres. ### Does a higher GSM mean a better fabric? No, it means a heavier one. A 110 GSM voile and a 300 GSM canvas are both good at their jobs. GSM tells you whether a cloth suits the garment, not whether it is well made. ### Where is the GSM on your product pages? Ask for it in an enquiry if it is not listed. Our specification lines give count, construction and width, and the GSM converter on this site turns any GSM you are quoted into ounces, grams per metre and metres per kilo. ## Sources - Grammage, Wikipedia: https://en.wikipedia.org/wiki/Grammage - Units of textile measurement, Wikipedia: https://en.wikipedia.org/wiki/Units_of_textile_measurement --- # How to Read a BTCPL Swatch Card: Shades, Count, Construction and Stock URL: https://btcpl.co.in/resources/sourcing-guides/how-to-read-a-swatch-card Updated: 2026-10-19 > A page in a BTCPL swatch book is one design. A large swatch shows the base cloth and smaller pinned swatches lettered A to G show the other shades it is stocked in. The printed header gives the design number, count, construction, quantity and finish, and the design number is what you quote in an enquiry. ## What is on a swatch card? Each page in our swatch books is one design. The large piece of cloth is the base shade, cut big enough to feel the hand and see the weave at arm's length. Down one side are smaller swatches of the same cloth in the other shades we stock, each pinned to the page and marked with a letter. The printed header at the top names the design and gives its count, construction, quantity and finish, with a barcode for our own stock system. The foot of the page carries the office and warehouse addresses, so a page that leaves the building still says where it came from. [Video: A week of our swatch books: a texture dobby, a stripe, a check, a slub and a seersucker. Six pages from our swatch books, one per day. Each shows the large base swatch, the pinned shade swatches with their letters, and the printed header with the design number and construction.] ## Shade letters The small swatches are lettered A, B, C and onwards down the page. A letter is only a shade code, and it means something only together with the design number. Quote both in an enquiry. A design can have a handful of shades or a full run to G and beyond, and the base shade shown large is one of them. ## The header The header repeats the fields you will find on a product page in our catalogue. Count is the fineness of the yarn, construction (printed as Con) is the warp ends and weft picks per inch, and finish is the treatment the cloth had after weaving. Those three are explained in [how to read a woven fabric specification](/resources/sourcing-guides/how-to-read-a-fabric-specification). Quantity is the stock on the day the card was printed. The catalogue page shows the live figure, because stock is updated continuously. ## From the book to the catalogue Type the design number from the header into the catalogue search and the product page comes up with its specification, the metres in stock and, for registered buyers, the photographs. A buyer who has the book in hand and the catalogue open can shortlist a season's fabrics without a visit. ## At our stand At a trade fair the books sit on the table and the sample garments hang behind them. Buyers go through the pages, pull a shade swatch to the light, and check it against a garment cut from the same cloth. Each sample garment carries a fabric-details tag with the same fields as the card, so the cloth, the shade and the spec can be matched on the spot. [Video: Our stand at a trade fair in October 2026. Buyers at the BTCPL stand go through the swatch books on the table, hold shade swatches up to the sample garments on the rail, and read the tags on the garments.] ## Frequently asked questions ### What do the letters next to the small swatches mean? They are the shade codes for that design. Quote the design number and the letter together, for example 9072G with shade D, and we know exactly which cloth and colour you mean. ### Is the large swatch a different fabric from the small ones? No. It is the same design in its base shade, cut large so you can feel the weight and see the weave. The small swatches are the same cloth dyed in the other shades. ### Is the quantity printed on the card the current stock? It is the stock on the day the card was printed. The product page in our catalogue shows the metres available now, because stock is updated continuously. ### Can I get a swatch sent to me? Yes. Send an enquiry with the design number and the shade letter from the card, and we will cut swatches from the roll. ## Sources - Textile sample, Wikipedia: https://en.wikipedia.org/wiki/Textile_sample - How to read a woven fabric specification, Bang Textiles: https://btcpl.co.in/resources/sourcing-guides/how-to-read-a-fabric-specification --- # Seersucker Fabric: What It Is, How the Pucker Is Woven and What It Is Used For URL: https://btcpl.co.in/resources/fabric-wiki/seersucker-fabric Updated: 2026-10-19 > Seersucker is a lightweight cotton cloth with permanently puckered stripes. The pucker is woven in, by weaving with two warps held at different tensions, so it does not iron out and does not need ironing. The crinkle holds the cloth off the skin, which is why it is a summer fabric. ## What is seersucker? Seersucker is a thin cotton cloth whose stripes are made of pucker, with no print or dye needed to show them. The name comes through Hindi and Urdu from the Persian for milk and sugar, a description of the smooth and rough stripes side by side. The cloth was taken up for hot climates because the pucker holds it slightly away from the body, and it has stayed a summer fabric ever since. [Video: A seersucker swatch lifted to show its pucker. A short AI-generated clip of a hand lifting a folded blue and white seersucker swatch so the puckered stripes catch the light.] ## How is the pucker woven? A seersucker loom carries two warps. One is held at normal tension and weaves flat. The other is fed slack, so as the weft is beaten in those threads bunch up and the stripe they form puckers. Because the pucker is made by the structure of the weave, it survives washing and wear for the life of the garment. A fabric with a similar look can be made by pressing or chemically crinkling a flat cloth after weaving, but that finish is applied to the surface and can soften with washing. ## Stripes and solids The classic seersucker is a yarn-dyed stripe of one colour against white, with the pucker running along the coloured stripe. A plain-dyed seersucker is woven undyed and dyed afterwards, so the whole cloth is one colour and the stripes show as texture alone. Our seersucker range is made this way and offered in a run of shades, each pinned to the page of its swatch book. The difference between the two dyeing routes is explained in [yarn-dyed vs piece-dyed fabric](/resources/weave-glossary/yarn-dyed-vs-piece-dyed). ## What is seersucker used for? The cloth is light and the pucker keeps it off the skin, so it goes into summer shirts and unlined suits, and into dresses and children's clothes. It also turns up in bedding for the same reason. Because it is not meant to be pressed flat, it suits garments that are washed often and worn without ironing. A seersucker shirt and a plain poplin shirt from the same cotton yarn will weigh about the same, but the seersucker will feel cooler on a hot day. ## Specifying a seersucker A seersucker is specified like any woven cotton, by composition, count, construction and width, and the lines on our product pages follow that order. The pucker makes the usable width slightly less than a flat cloth woven on the same loom, so take the width from the card before you plan a marker. How to read those lines is covered in [how to read a woven fabric specification](/resources/sourcing-guides/how-to-read-a-fabric-specification), and how to read the page in the swatch book in [how to read a BTCPL swatch card](/resources/sourcing-guides/how-to-read-a-swatch-card). ## Frequently asked questions ### Does seersucker need ironing? No. The pucker is part of the weave, so the cloth is meant to look crinkled. Wash it, shake it out and hang it. Ironing flattens the stripes for a while and they return with the next wash. ### Is seersucker the same as crinkle cotton? Not quite. Seersucker's pucker is woven in with a slack warp and is permanent. Crinkle finishes are pressed or chemically set into a flat cloth after weaving and can fade with washing. ### Why is seersucker cool to wear? The puckered stripes hold part of the cloth away from the skin, so air moves between fabric and body. The cloth is also thin and usually cotton, which absorbs sweat. ### Can seersucker be made in a solid colour? Yes. The classic look is a yarn-dyed blue and white stripe, but the pucker shows just as clearly in a piece-dyed solid, which is how the shades in our swatch book are made. ## Sources - Seersucker, Wikipedia: https://en.wikipedia.org/wiki/Seersucker --- # Yarn Count Explained: Ne, Nm, Tex and Denier on a Fabric Specification URL: https://btcpl.co.in/resources/weave-glossary/yarn-count-explained Updated: 2026-10-19 > Yarn count tells you how fine a yarn is. Cotton is usually given in English cotton count (Ne), where a higher number means a finer yarn: a 40s yarn is finer than a 20s. Metric count (Nm) works the same way, while tex and denier run the other way, with a higher number meaning a thicker yarn. ## What is yarn count? Yarn count is the number a spinner uses to say how fine a yarn is. There are two families of count, and they run in opposite directions. Indirect systems such as English cotton count and metric count measure length per unit of weight, so a finer yarn, which gives more length for the same weight, gets a higher number. Direct systems such as tex and denier measure weight per unit of length, so a finer yarn gets a lower number. The word "count" on a woven cotton spec almost always means English cotton count. ## English cotton count (Ne) English cotton count is the number of 840-yard hanks that weigh one pound. A 20s yarn gives twenty hanks to the pound and a 40s gives forty, so the 40s is half the weight for the same length and twice as fine. Written as 20s or 40s, and on a card as warp × weft, such as the 20 x 20 on our Piece Dyed Texture Dobby 9072G. Shirting cottons are commonly spun in the 40s to 80s range, and the heavier cloths for trousers and jackets in the 10s to 30s. ## The other three count systems Metric count (Nm) is the length in metres of one gram of yarn, so it rises with fineness like Ne and converts at Nm = Ne × 1.693. Tex is the weight in grams of 1,000 metres and denier the weight in grams of 9,000 metres, so both fall as the yarn gets finer, and denier is always nine times tex. European mills tend to quote Nm, laboratories quote tex, and filament yarns such as viscose and polyester are quoted in denier. | Ne | Nm | Tex | Denier | | --- | --- | --- | --- | | 10s | 17 | 59 | 532 | | 20s | 34 | 29.5 | 266 | | 40s | 68 | 14.8 | 133 | | 60s | 102 | 9.8 | 89 | | 80s | 135 | 7.4 | 66 | [Video: Four cotton yarns, from thick to fine. A short AI-generated clip panning across four undyed cotton cones, from the thickest yarn on the left to the finest on the right.] ## Plied yarns and blends A single yarn is one strand. A plied yarn is two or more singles twisted together, written 60/2 or 2/60 for two 60s singles. The ply is roughly as thick as a 30s single but stronger and more even, which is why fine shirtings are often woven from two-ply yarn in the warp. On a blended cloth the count line still gives warp and weft the same way. The tag on our BTC-9112 sample garment, an 80% viscose and 20% linen cloth, reads 12 x 12. [Image: The fabric-details tag on a BTCPL sample shirt, listing design number, count, construction, blend, weave, width, GSM and finish — The count line on our BTC-9112 sample tag reads 12 x 12.] ## Count and construction together Count on its own does not say how dense the cloth is. That is the job of construction, the number of warp ends and weft picks per inch, and the two are read together. A 40s yarn at 132 x 72 is a fine, close poplin. The same 40s yarn at 60 x 50 is an open, light cloth. How count and construction combine into the weight and hand of a fabric is covered in [how to read a woven fabric specification](/resources/sourcing-guides/how-to-read-a-fabric-specification). ## Frequently asked questions ### Is a higher yarn count finer or coarser? In Ne and Nm, finer. A 60s cotton yarn is finer than a 40s because more hanks of it go into a pound. In tex and denier, coarser, because those count the weight of a fixed length. ### What does 20 x 20 mean on a fabric spec? The warp yarn is 20s and the weft yarn is 20s, both in English cotton count. The first number is always the warp, the yarn that runs along the roll. ### What does 60/2 or 2/60 mean? A two-ply yarn made by twisting two 60s singles together. It behaves roughly like a 30s single in thickness, but is stronger and more even. Both ways of writing it mean the same thing. ### How do I convert cotton count to tex? Divide 590.5 by the Ne number. A 20s yarn is about 29.5 tex, a 40s about 14.8 tex, and a 60s about 9.8 tex. ## Sources - Units of textile measurement, Wikipedia: https://en.wikipedia.org/wiki/Units_of_textile_measurement --- # Dobby Fabric: What It Is, How It Is Woven and What It Is Used For URL: https://btcpl.co.in/resources/fabric-wiki/dobby-fabric Updated: 2026-10-05 > Dobby fabric is cloth with a small pattern woven into it by a dobby loom, such as dots or a fine surface texture. The pattern is part of the weave, so it does not wash off, and the cloth can be dyed either as yarn or as a finished piece. ## What is dobby fabric? Dobby fabric is a woven fabric whose small pattern is produced by the loom itself. The dobby that gives the fabric its name is a device on the loom that raises groups of warp threads in a programmed sequence, so on each pass the weft goes over some threads and under others in a repeating order. The pattern this produces, whether dots, checks, diamonds or a fine surface texture, is in the structure of the cloth, which is why it survives washing in a way a print does not. ## How is a dobby woven? A dobby loom controls the warp threads through harness shafts, and each shaft lifts one group of threads. The dobby decides which shafts rise on each pass of the weft. An eight-shaft dobby can form up to 254 different sheds, which is why a dobby weaves far more varied patterns than a simple tappet loom, and smaller, more geometric ones than a jacquard. ## Dobby vs jacquard vs plain weave | Weave | How threads are controlled | Pattern it can make | Typical look | | --- | --- | --- | --- | | Plain weave | Two shafts, alternating | None (over one, under one) | Flat, even surface | | Dobby | Groups of threads via multiple shafts | Small geometric repeats and textures | Fine dots, checks, diamonds, texture | | Jacquard | Each warp thread individually | Large, detailed figures | Florals, brocades, damasks | [Image: Diagram of plain weave, dobby and jacquard weave structures, each drawn as a grid of warp and weft crossings — How the three weaves lift their warp threads. The red box marks one pattern repeat.] ## Yarn-dyed and piece-dyed dobbies A dobby can be woven from coloured yarn, which lets the pattern show in more than one colour. It can also be woven undyed and dyed afterwards as a whole piece, which gives one solid colour with the texture showing through. Our Piece Dyed Textured Dobby range is made the second way, from one base cloth dyed into a range of colours. [Image: Six cotton dobby fabric swatches in olive, black, burgundy, brown, navy and off-white laid out on linen — One base cloth, dyed into a shade card.] ## Reading a dobby specification A dobby is specified like any woven cotton, by composition, yarn count, construction and width. Piece Dyed Texture Dobby 9072G in our catalogue, for example, is 100% cotton, 20 x 20 count in warp and weft, 64 x 44 construction (ends and picks per inch) and 57–58 inches wide. If the garment needs a particular weight, ask for the GSM as well. Our [GSM converter](/tools/gsm-calculator) turns it into ounces per square yard and grams per running metre. [Image: Olive cotton dobby fabric made into a casual shirt, hanging on a wooden hanger — Where a texture dobby usually ends up.] ## Frequently asked questions ### What is the difference between dobby and jacquard fabric? A dobby loom lifts warp threads in groups through a limited number of harness shafts, so its patterns are small and geometric. A jacquard loom controls each warp thread on its own, which allows large, detailed figures such as florals and brocades. ### Is dobby fabric the same as textured fabric? Not always. Dobby describes how the fabric is woven. Many dobbies have a visible texture, but a texture can also come from a slub yarn or from a finishing process. A texture dobby is a dobby whose woven pattern reads mainly as surface texture. ### Can dobby fabric be dyed after weaving? Yes. A dobby can be woven from dyed yarn (yarn-dyed) or woven in greige and dyed as a whole piece afterwards (piece-dyed). The woven pattern stays visible either way because it is in the structure of the cloth. ### What does 20 x 20 count and 64 x 44 construction mean on a dobby specification? 20 x 20 is the yarn count of the warp and weft in English cotton count (Ne). 64 x 44 is the construction, which is 64 warp ends and 44 weft picks per inch. ## Sources - Dobby loom, Wikipedia: https://en.wikipedia.org/wiki/Dobby_loom - Units of textile measurement, Wikipedia: https://en.wikipedia.org/wiki/Units_of_textile_measurement --- # How to Read a Woven Fabric Specification: Count, Construction, Width and GSM URL: https://btcpl.co.in/resources/sourcing-guides/how-to-read-a-fabric-specification Updated: 2026-10-05 > A woven fabric specification tells you what the cloth is made of (composition), how fine the yarn is (count), how densely it is woven (construction, in threads per inch), how wide it is, and how heavy it is (GSM). Read together, those five lines are enough to compare two fabrics without touching either. ## What is on a woven fabric specification? Every product page in our catalogue lists the same fields, which are finish, composition, width, colour, weave, count and construction. Read together they describe the cloth precisely enough to compare two fabrics without touching them. ## Composition Composition is the fibre content by weight, for example 100% cotton or a cotton-linen blend. It decides how the fabric feels in the hand, how it breathes, how much it shrinks and how it takes dye. ## Count Count is how fine the yarn is. Cotton yarn is usually given in English cotton count (Ne), which is the number of 840-yard hanks that weigh one pound. A higher count means a finer yarn. A spec such as 20 x 20 gives the warp count first and the weft count second. [Image: Diagram of yarn count (Ne) from 20s to 80s and a 64 x 44 construction drawn as threads per inch — Count is the fineness of the yarn. Construction is how many of those yarns fit in an inch.] ## Construction Construction is how many threads are woven into each inch, with warp ends first and weft picks second. 64 x 44 means 64 ends and 44 picks per inch. More threads per inch generally means a denser, firmer cloth. [Image: Counting threads per inch through a pick glass on plain-woven cotton — A pick glass frames one square inch, or one centimetre, for counting.] ## Width and GSM Width is the usable width of the roll, usually in inches, and multiplying by 2.54 gives centimetres. GSM is the weight of one square metre in grams. Width and GSM together give the weight of a running metre, which is what decides how many metres are in a kilogram. Our [GSM converter](/tools/gsm-calculator) does that arithmetic. [Image: Diagram showing fabric width measured across the roll from selvedge to selvedge — Full width runs selvedge to selvedge. Usable width is an inch or two less.] [Image: Measuring the width of a navy cotton roll from selvedge to selvedge with a tape measure — Measure at more than one point along the roll and take the lowest reading.] ## A worked example from our catalogue Piece Dyed Texture Dobby 9072G is listed as finish NSF, composition 100% cotton, width 57–58 inches, weave dobby, count 20 x 20 and construction 64 x 44. That reads as a medium-weight cotton dobby, woven from 20s yarn in both directions at 64 by 44 threads per inch, on a roll about 145 to 147 cm wide. ## The same fields on a sample garment At trade fairs we hang sample garments with a fabric-details tag, so a buyer can read the cloth without opening a swatch book. The tag on this shirt and trouser set lists design BTC-9112, count 12 x 12, construction 56 x 46, blend 80% viscose and 20% linen, weave plain, width 55–56 inches, GSM 214 and finish NSF. Those are the same seven fields as a product page, in the same order a mill would quote them. The garments are cut for sampling only and are not for sale. [Video: Sample shirt and trousers in BTC-9112 viscose-linen, with its fabric-details tag. A clip from our stand at a trade fair. A sample shirt and trouser set hangs among the plain-dyed fabrics it was cut from, and the tag on the shirt lists the design number, count, construction, blend, weave, width, GSM and finish.] ## Frequently asked questions ### Is a higher yarn count finer or coarser? Finer. English cotton count (Ne) is the number of 840-yard hanks in one pound of yarn, so a 40s yarn is finer than a 20s yarn. ### What does 64 x 44 mean on a fabric spec? It is the construction, which is 64 warp ends and 44 weft picks per inch. Higher numbers mean a denser weave. ### How do I convert GSM to ounces per square yard? Divide the GSM by 33.9057. A 145 GSM fabric is about 4.28 oz/yd². ## Sources - Units of textile measurement, Wikipedia: https://en.wikipedia.org/wiki/Units_of_textile_measurement - Grammage, Wikipedia: https://en.wikipedia.org/wiki/Grammage --- # Yarn-Dyed vs Piece-Dyed Fabric: The Difference and How to Choose URL: https://btcpl.co.in/resources/weave-glossary/yarn-dyed-vs-piece-dyed Updated: 2026-10-05 > Yarn-dyed fabric is woven from yarn that was dyed first, which is how a woven stripe or check gets its colour. Piece-dyed fabric is woven undyed and dyed as a whole piece afterwards. That suits solid colours and lets one base cloth be dyed into many shades. ## What is yarn-dyed fabric? Yarn-dyed fabric is woven from yarn that has already been dyed. Each warp and weft thread can be a different colour, so the colour pattern is built in as the cloth is woven. Stripes, checks, plaids and chambray are all made this way. [Image: Dyed cotton yarn cones in indigo, white, red and sky blue on a mill creel — Yarn is dyed on the cone, then woven.] ## What is piece-dyed fabric? Piece-dyed fabric is woven first, usually from undyed yarn, and the whole length of cloth is dyed afterwards. It comes out in one solid colour. Because the same base cloth can go into any dye bath, a piece-dyed range can offer one fabric in a full shade card. ## Yarn-dyed vs piece-dyed at a glance | | Yarn-dyed | Piece-dyed | | --- | --- | --- | | When colour is added | Before weaving | After weaving | | Patterns | Stripes, checks, chambray, multi-colour | Solid colour; woven texture shows through | | Colour range from one cloth | Fixed when woven | Many shades from one base cloth | | Typical garments | Shirts with stripes or checks | Solid shirts, dresses, trousers | [Image: Close-up of chambray fabric showing coloured warp and white weft threads — Chambray: a coloured warp crossed by a white weft.] ## Which should you choose? Choose yarn-dyed when the design needs more than one colour woven in. Choose piece-dyed when the design is a solid colour or a single-colour texture, such as a piece-dyed dobby, or when you want the same cloth in several shades. [Image: A thread pulled from the frayed edge of yarn-dyed striped fabric, coloured all the way through — The thread test: a yarn-dyed thread is coloured right through.] ## Frequently asked questions ### How can I tell if a fabric is yarn-dyed or piece-dyed? Pull a thread from the cut edge. In a yarn-dyed fabric each thread is coloured all the way through, because it was dyed before weaving. In a piece-dyed fabric the thread was undyed when woven and the colour was added to the finished cloth. A woven stripe or check is almost always yarn-dyed. ### Is chambray yarn-dyed? Yes. Chambray is a plain-weave fabric with a coloured warp and a white or undyed weft, which is what gives it its mottled look. That effect needs the yarn dyed before weaving. ### Can a piece-dyed fabric have a pattern? It can have a woven texture, as a piece-dyed dobby does, but the whole piece takes one colour. Multi-colour stripes or checks need yarn-dyed yarn or printing. ## Sources - Dyeing, Wikipedia: https://en.wikipedia.org/wiki/Dyeing - Chambray, Wikipedia: https://en.wikipedia.org/wiki/Chambray ---
