Sourcing Cotton Yarn from India: Counts, Combed vs Carded and Testing

India has one of the largest spinning industries in the world, and for a buyer that is both the opportunity and the difficulty. Capacity is abundant and competitively priced. Quality spans everything from mills supplying European shirting brands to units producing yarn that will not run on a modern loom.

The difference between the two is not usually visible in a sample cone. It is visible in a test report, and in whether the mill can repeat the result.

Count: the number everyone quotes

Yarn fineness in the Indian trade is expressed in Ne, the English cotton count: the number of 840-yard hanks that weigh one pound. It is an indirect system, so a higher number means a finer yarn.

Common counts and their typical uses:

Two things to specify alongside the count. The tolerance, because count varies and a yarn consistently at the coarse end of tolerance delivers less length per kilo. And the CV of count, which describes variation between and within bobbins.

You will also encounter Nm (metric count) and tex or dtex (direct systems, where a higher number means a coarser yarn). Confirm which system a quotation uses; confusion between Ne and Nm is a real and expensive error.

Combed or carded

Every cotton yarn is carded — opened, cleaned and formed into a sliver. Combing is an additional process that removes short fibres and neps and aligns the remainder.

Combed yarn is smoother, stronger, more even, has fewer imperfections and produces cleaner fabric. It costs more, both because of the extra process and because combing removes a meaningful percentage of the fibre as noil.

The rule of thumb: combed for anything where fabric appearance matters or above roughly Ne 40; carded where bulk, cost or a rustic handle are acceptable. Specify a comb noil percentage if you want to be precise, because "combed" covers a range and a light comb is not the same product as a heavy one.

Spinning system

Ring spinning twists fibres around a rotating spindle. It produces the strongest, finest, smoothest yarn and is what fine counts require. More expensive per kilo.

Open end, or rotor spinning, forms yarn in a rotating rotor. Faster and cheaper, produces a bulkier, more absorbent yarn with a different surface character, and does not reach fine counts. Standard for denim, terry towelling and coarse counts.

Compact spinning is a ring variant that condenses the fibre strand before twist is inserted, reducing hairiness and increasing strength. It is used for premium shirting and for any application where pilling or a clean fabric surface matters, and it carries a premium over conventional ring spun.

Vortex and air-jet systems produce yarns with their own distinct characteristics — low hairiness, good pilling resistance, a firmer handle — and are used in specific applications, particularly in blends and in fabrics where abrasion resistance matters more than softness.

These are genuinely different products, not quality grades. A denim mill buying ring spun for a fabric designed around open end will get a fabric that does not look right, and vice versa.

The parameters that decide whether yarn runs

This is where the specification separates buyers who have problems from those who do not.

Count and count CV. Fineness and its variation.

Twist and twist multiplier. Twist per inch or per metre. Higher twist gives strength and a harder handle; lower twist gives softness and bulk. Twist direction — S or Z — matters for some fabrics.

Strength. Expressed as single yarn strength in grams per tex, or as CSP (count strength product) in the Indian trade. Determines whether the yarn survives weaving or knitting tension.

Elongation. Percentage extension at break. Low elongation yarn breaks on the machine even when strength looks adequate.

Evenness — U% or CV%. Variation in mass along the yarn. Directly visible in the fabric as streakiness.

Imperfections. Thin places, thick places and neps per thousand metres. The parameter that most directly determines fabric appearance.

Hairiness. Protruding fibre ends. Affects fabric handle, pilling and, in weaving, shed clarity.

Classimat faults. A classification of rare, large faults that a normal evenness test will not catch but which produce visible fabric defects.

Specify these as numbers, or as Uster percentile levels, which express each parameter as a percentile against world production and make suppliers directly comparable.

Contamination: the problem that appears after dyeing

Contamination deserves its own section because it is invisible when you buy and expensive when it appears.

Foreign material — coloured fibre, jute, hair, and above all polypropylene from the woven packing material used throughout the cotton supply chain — gets spun into the yarn. It cannot be seen in a white or grey yarn. After dyeing, the contaminant takes dye differently and appears as a coloured fleck or streak in the fabric.

By that point the fabric has been woven or knitted, dyed and finished, and the loss is many times the yarn value.

Controls:

Ask what the mill does about it. Serious mills run contamination removal — manual sorting at the bale opening stage, and increasingly optical contamination sorters in the blow room. Ask which, and ask to see it.

Specify a contamination limit and a test method, typically counts per unit weight from a defined sample.

Ask about packing. Cotton bales bound and wrapped with polypropylene are a primary source, and mills that specify cotton or paper packing from their suppliers have removed a large part of the risk.

Test before you dye, not after. A contamination test on arrival costs little; discovering it in finished fabric costs everything downstream.

Cotton itself

The yarn inherits its ceiling from the fibre, and the fibre parameters are worth understanding.

Staple length — the average fibre length. Longer staple permits finer counts and produces stronger, smoother yarn. Indian cotton spans short, medium and long staple; extra-long staple is imported or grown in limited quantity.

Micronaire — a measure of fineness and maturity. Outside the acceptable band, dye uptake becomes uneven.

Strength, measured in grams per tex on the fibre.

Trash content — non-lint material such as leaf, seed coat and dust, which the blow room and cards remove at a cost in fibre loss and machine time.

Short fibre content — the percentage below a defined length, which drives imperfections and hairiness and is the reason combing exists.

Uniformity index — how consistent fibre length is within the sample, which affects spinning performance independently of the average.

A mill that can tell you the cotton mix behind your yarn, with these parameters, is running a controlled process. One that cannot is buying to a price each week, and your yarn will vary accordingly.

Where it is spun

Coimbatore, Tiruppur, Erode and Salem, Tamil Nadu. The densest spinning belt in India, with Tiruppur additionally the country's largest knitwear cluster. Deep capability across counts, and the natural first look for most buyers.

Ahmedabad and Gujarat. Large spinning capacity alongside a substantial weaving and processing base.

Ludhiana and Punjab. Strong in knitwear and in the yarn supply that feeds it, particularly woollen and blended yarns alongside cotton.

Kolhapur, Ichalkaranji and Maharashtra. Significant spinning and weaving.

Andhra Pradesh and Telangana. Growing capacity, close to cotton growing areas, which shortens the fibre supply chain and can help both cost and traceability.

Madhya Pradesh. A centre for organic cotton growing and increasingly for its processing, which matters if certified organic supply is your requirement.

For a buyer, cluster choice usually follows what happens next: if you are buying yarn to have fabric made in India, buying near the weaver or knitter removes an inland freight leg and a coordination problem.

Blends and specialty yarns

Pure cotton is the largest category and far from the only one Indian mills spin.

Polyester-cotton blends, commonly 65/35 or 52/48, sit under HS 5206 or the man-made fibre headings depending on composition. Specify the blend ratio and its tolerance, because ratio drift changes dye uptake and shrinkage.

Viscose and modal blends for softer handle and drape.

Melange and grindle yarns, where dyed fibre is blended before spinning to produce a heathered effect. Shade consistency between lots is the perennial problem, and it is controlled by fixing the dyed-fibre percentage and holding a physical reference.

Organic cotton, certified under GOTS or OCS. As with all certified claims, check the scope covers the specific mill and product, and understand that certification covers chain of custody rather than yarn quality.

BCI and other sustainability programmes, increasingly requested by European brands, and operating on a mass-balance rather than physical-segregation basis in some schemes — which is worth understanding before you make a claim about the yarn in a specific garment.

Recycled cotton, from pre- or post-consumer waste, usually blended with virgin fibre because recycled fibre is short. Expect lower strength and more imperfections, and specify accordingly rather than expecting virgin performance.

Each of these adds a parameter to the specification. A blend needs its ratio; a melange needs its shade reference; a certified yarn needs its certificate scope and transaction certificates.

Pricing and how yarn is quoted

Cotton yarn pricing is unusually transparent by the standards of this guide series, because raw cotton is an exchange-traded commodity and conversion costs are broadly known.

A yarn price decomposes into cotton cost, driven by domestic and international cotton prices and by the specific mix, plus conversion cost, which covers spinning, energy, labour and overhead and varies by count — finer counts cost more to spin per kilo because the machine produces less weight per hour.

Three consequences.

Cotton moves and yarn follows. A mill cannot hold a price through a significant cotton move, and one who offers to is either carrying the risk in the price or expects to renegotiate. Ask how long the quotation is firm.

Finer counts carry a steeper conversion premium. The step from Ne 30 to Ne 40 costs more than the fibre difference alone.

Combing has a visible cost. Combed yarn carries both the extra process and the value of the noil removed, so the combed premium is real rather than a marketing margin.

Where the negotiating room sits: volume and scheduling, which help a mill plan; count consolidation, since fewer counts means fewer changeovers; and payment terms, which matter to a working-capital-intensive business. There is little room in the cotton itself.

Packing, transit and storage

Cotton yarn ships in cones on pallets, in cartons or bags. Three practical points.

Cone specification matters. Cone taper, weight and paper or plastic construction must suit your machine's creel. This is routinely left unspecified and routinely wrong on a first delivery.

Moisture regain. Cotton absorbs and releases moisture, and yarn is sold by weight. Regain conditions are conventionally specified, and a shipment delivered wet is a shipment where you paid for water. Specify the regain basis.

Contamination in transit. Damaged packing lets in dirt and foreign fibre. Specify packing that survives the journey, particularly for a long ocean leg.

What goes wrong, and what it looks like

Six failure modes account for most complaints in yarn, and each maps to a parameter you either specified or did not.

Shade variation between lots. Appears after dyeing as barré or streakiness across a fabric roll. Almost always a change in the cotton mix. Controlled by mixing discipline, lot traceability and a reserved mix where volume justifies it.

Excessive breakage on the machine. Low strength, low elongation, or high imperfections. Controlled by specifying all three rather than strength alone — a yarn can be strong and still break if elongation is low.

Visible unevenness in fabric. High U% or CV%, or Classimat faults that routine evenness testing missed. Controlled by specifying both.

Pilling and poor handle. Frequently hairiness, sometimes fibre quality. Controlled by specifying hairiness and by choosing compact spinning where it matters.

Contamination. Covered above, and the most expensive of the six because it surfaces last.

Count drift. Yarn consistently at one end of tolerance, delivering less length per kilo than expected. Controlled by specifying count CV and by checking count on arrival.

Note the pattern: five of the six are invisible in a cone of undyed yarn and become visible only in fabric, after substantial value has been added. That asymmetry is the whole argument for testing yarn on arrival rather than trusting the certificate.

Testing on arrival: what is worth doing

You do not need a full textile laboratory to protect yourself, and a modest testing regime catches most of what matters.

The first three are within reach of any mill or warehouse. The last two are worth sending to a commercial textile laboratory for a first lot from a new supplier, and periodically thereafter.

The comparison that matters is between the supplier's own reported data and your independent result on the same lot. Across three shipments, that delta tells you whether the mill's laboratory is honest, optimistic, or simply sampling badly — and it is worth more than any certificate.

Verifying a spinning mill

The four-layer approach in our supplier verification guide applies, with four sector-specific additions.

Ask for the machinery list. Make, model and age of blow room, cards, combers, speed frames and ring frames or rotors. Modern, well-maintained machinery produces measurably better yarn, and a mill will tell you.

Ask to see the testing laboratory. A serious spinning mill runs evenness testing, strength testing and fibre testing as routine, in a temperature and humidity controlled room because textile testing is sensitive to both. Ask to see a test being run, and ask for last month's data on the count you intend to buy rather than a curated sample.

Ask about contamination control specifically, as above — what equipment, what manual sorting, and what they require of their cotton suppliers on packing material. This is the question that separates mills serving export knitwear from those serving domestic coarse counts.

Ask what else they supply. A mill already supplying a demanding export customer, or a domestic brand with real standards, has been audited by someone with more leverage and more expertise than you are likely to bring. That is worth more than any certificate they hold, and most mills will tell you if you ask.

Holding consistency across shipments

Consistency is a harder problem than quality, and it is the one that determines whether a supplier relationship works.

The mechanism behind most inconsistency is straightforward. A spinning mill buys cotton continuously at market prices and blends it into a mix. When cotton prices move or a particular growth becomes scarce, the purchasing team adjusts the mix — entirely rationally, and without anyone deciding to change your yarn. The count stays the same, the strength report stays within specification, and the fabric dyes a different shade.

Four controls, in increasing cost:

Specify the mix parameters, not just the yarn parameters. Staple length, micronaire and strength ranges for the fibre constrain how far the mix can drift.

Require lot traceability, so a shade problem can be traced to a mix and the mix to a cotton purchase.

Ask for a reserved mix. Where your volume justifies it, a mill will hold a defined blend for you. This is the single most effective control and it costs a premium.

Buy larger lots less often. A single large lot dyed together removes the problem for that quantity, at the cost of carrying more inventory.

Where none of these is available — small volumes from a large mill — the honest answer is to design around the variation: dye in larger batches, allow shade bands in your fabric specification, and hold a physical reference rather than expecting a match to a number.

A first-order checklist

1. Specify count with tolerance and count CV.
2. Specify combed or carded, with noil percentage if it matters.
3. Specify spinning system — ring, compact, open end.
4. Specify twist and direction.
5. Specify strength, elongation, evenness, imperfections and hairiness, ideally as Uster percentiles.
6. Specify a contamination limit and test method.
7. Specify cone type, weight and packing, and the moisture regain basis.
8. Ask for the mill's own test data for your lot, not a generic certificate.
9. Run a trial lot on your own machinery before committing volume.
10. Test contamination on arrival, before dyeing.

Classification and compliance

Cotton yarn sits in Chapter 52, and the heading depends on composition and presentation.

5205 covers cotton yarn containing 85 percent or more cotton by weight, not put up for retail sale. This is the heading for most commercial yarn purchases.

5206 covers cotton yarn with less than 85 percent cotton — the blend heading.

5207 covers cotton yarn put up for retail sale.

Within 5205 the sub-headings split by whether the yarn is single or multiple, whether it is combed or uncombed, and by count band expressed in decitex. That last point is worth noting: the tariff bands are defined in metric terms while the trade quotes in Ne, so your broker will need the conversion. Get the classification confirmed rather than assuming, because count bands sit close together and a yarn near a boundary can fall either side.

On compliance, three things arise for textile imports.

Origin, where a preferential claim is made. Yarn is usually straightforward, being spun from fibre in one place, but verify rather than assume.

Chemical compliance, where relevant — REACH in the European Union, and restricted substance lists imposed by brands. Yarn is a lower-risk stage than dyed fabric, but certified organic and some finished yarns carry chemical questions.

Certification transaction documents for organic or recycled claims, which must accompany each shipment rather than existing once at mill level.

Lead times and what drives them

Indian mills are fast for standard counts in cotton they already hold: two to four weeks of production for a container quantity is normal, and the constraint is machine scheduling rather than capability.

Three things extend it. A count they do not currently run requires a changeover, which mills schedule rather than perform on demand. A specific cotton mix requires procurement. And certified organic or recycled yarn requires segregated processing, which mills batch.

Add the usual documentation and booking time and a first order commonly runs eight to twelve weeks from confirmation to arrival, with repeats faster.

The planning point: mills allocate machine hours weeks ahead, and a customer who orders sporadically is scheduled around one who orders predictably. Regular, forecast volume genuinely buys you both better pricing and better priority, which is one of the few places in sourcing where those two align.

Where Katalyzon fits

We do not spin yarn and take no position in the goods. We establish whether a mill owns the machinery and testing capability they are quoting, verify registrations against evidence we can show you, and coordinate the inspection and testing that confirms a lot meets the specification before your money moves.

Post a requirement with the count, quality parameters and volume, and our desk will scope it. Every brief is read by a person before anything is routed, and your details stay masked until you accept a quote. You can also browse the marketplace for indicative specifications.

The short version

Buy yarn on a specification, not on a count and a price. Count, combed or carded, spinning system, twist, strength, elongation, evenness, imperfections and hairiness together determine whether the yarn runs and how the fabric looks — and every one of them is a number a competent mill measures as routine.

Then take contamination seriously, because it is the one defect that is invisible when you buy and ruinous when it appears. Ask what the mill does about it, specify a limit, and test on arrival rather than after dyeing.
