Combed or carded cotton: does it matter for T-shirts?

Short answer: Yes, it usually matters, especially for a basic tee that is judged on feel and surface. Carding opens and aligns cotton fibres but leaves more short fibres and impurities in the sliver. Combing is an extra step that removes a share of the short fibres and neps and aligns the longer fibres further, so the yarn is more even, smoother and stronger at the same count. In a T-shirt this tends to give a softer hand, a cleaner surface, less fuzzing and pilling, and a better base for fine screen prints and DTG. Carded cotton is cheaper and is fine for promotional tees, workwear or heavily washed looks where surface is less important. Ask for the yarn type and count in writing and compare washed samples side by side.

What combing changes

• Fewer short fibres, so fewer loose ends to fuzz and pill.
• More even yarn, so the fabric looks cleaner and less blotchy after dyeing.
• Stronger yarn at the same count, which allows finer counts.
• Higher cost because of the extra process and fibre loss.

Where carded is acceptable

• Promotional and event tees with a short expected life.
• Heavier, rugged tees where a dry, textured hand is part of the look.
• Garments that will be heavily washed or distressed.

How to check

• Ask for the yarn spec, for example 30s combed ring-spun, on the quotation and purchase order.
• Compare fabric faces under good light: carded jersey often shows more neps and a hairier surface.
• Run a pilling test with ISO 12945-2 on both fabrics after washing.
• Compare GSM and width so the comparison is not just a weight difference.

A worked example

A brand tests both options at the same weight. After five washes the carded shirt shows light fuzzing at the sides and a slightly duller colour, while the combed shirt looks close to new. The price difference is small per shirt compared with the retail price, so the brand chooses combed for its core basics and keeps carded for event merchandise.

Limits

Combing improves the yarn but does not guarantee quality; fibre grade, spinning method, knitting and finishing also affect the result. Labels such as "premium cotton" are not proof of combing.

Facts, recommendations and uncertainty

Established: combing removes short fibres and neps, giving smoother, more even yarn. Recommendation: specify yarn type and count in writing and compare washed samples. Uncertain: whether your customers will pay for the difference at your price point.
