Carded cotton yarn is spun from fibre that has been opened and cleaned by carding alone, while combed yarn goes through an extra combing stage that removes the shortest fibres and remaining impurities before spinning. Combed yarn is smoother, stronger and more even, and it costs more because the combing process discards a share of the fibre. For a buyer, the choice sets the handle and appearance of the fabric and a meaningful part of the price.
What carding and combing do
Carding pulls the opened fibre through fine wire-covered rollers to separate and align the fibres into a loose sliver. Short fibres, neps and small trash remain in the sliver. Combing passes that sliver through a comb that holds the long fibres and strips out the short ones and any neps, producing a cleaner, more parallel sliver. The removed material, called comber noil, is typically a noticeable share of the input, which is why combed yarn costs more.
How the yarns compare
- Appearance: combed yarn is cleaner with fewer neps and specks, so it suits pale and bleached fabrics.
- Strength: combed yarn is stronger for the same count because the fibres are longer and better aligned.
- Hairiness: combed yarn is less hairy, giving a smoother surface and less pilling.
- Evenness: combed yarn has fewer thick and thin places, which shows clearly in knitted fabric.
- Cost: carded yarn is cheaper and is the normal choice for coarser counts and basic fabrics.
- Count range: carded yarn is usually spun up to around 40s; finer counts are almost always combed.
Which to specify
Use carded yarn for coarser counts, workwear, denim, towels, heavy knits and anywhere the fabric will be dyed in deep shades or brushed. Use combed yarn for fine shirting, premium T-shirts, bed linen in pale colours and any fabric where surface appearance and softness matter. Many fabrics in the 30s to 40s range are made in both versions, so the brief should state which one.
Ask what cotton the mill combs. Combing a medium-long staple such as Shankar-6 gives a good 30s to 40s combed yarn, but finer combed counts need a longer staple. A mill quoting a low price for 60s combed from Gujarat cotton may be blending or over-promising. Some mills also describe a lightly combed yarn as "semi-combed", which sits between the two in quality and price.
Yarn test reports from an instrument such as a Uster evenness tester show imperfections per kilometre, hairiness and strength, and those numbers separate carded from combed more reliably than the label. Request the report for the actual lot and keep a reference cone from the approved sample.
What we do
We visit the spinning mill to see that the combing line is running and matches what is being quoted, send sealed yarn samples to an NABL-accredited lab and supervise loading. We hold one approved spinner and one backup for each count and send a weekly update while your order is in production. A free 20-minute sourcing review will help you decide whether your fabric really needs combed yarn.
