COTTON TYPES EXPLAINED
COMBED, CARDED, ORGANIC

Every clothing brand founder eventually hits the same question: what cotton am I actually buying? Manufacturers throw around terms like "combed", "ring-spun", "organic", and "carded" as if buyers should already know the difference. Most don't | and that leads to inconsistent product quality, mispriced positioning, and wasted samples. This guide breaks down every major cotton distinction so you can specify exactly what you want in your tech pack.

Carded vs Combed Cotton | The Foundation

The first distinction is how raw cotton fibers are prepared before spinning into yarn.

Carded cotton passes through a carding machine that separates and aligns the fibers loosely. Short fibers stay in the mix. The result is yarn that's slightly uneven, less soft, and more prone to pilling. Standard t-shirts, workwear, and fast-fashion pieces typically use carded cotton because it's affordable and durable.

Combed cotton goes through an additional combing step that removes short fibers (under about 20mm) and impurities. Only the longer, stronger fibers survive. The yarn is smoother, softer, and stronger. Premium t-shirts and streetwear pieces almost always use combed cotton because it feels noticeably nicer on skin and holds up to washing better.

When you pick up a premium tee at a boutique and think "this feels different," combed cotton is often why. When you specify "combed cotton" in your tech pack, you're getting maybe 15% better material for a small unit cost bump.

Ring-Spun vs Open-End Spinning

After preparation, cotton is spun into yarn using one of two methods.

Ring-spun yarn is the older, higher-quality method. Fibers are twisted continuously into a longer, softer, stronger yarn. Ring-spun combed cotton is the "gold standard" for premium tees and hoodies.

Open-end (rotor) spinning is faster and cheaper. The yarn is bulkier and slightly rougher. It's used in denim, towels, and budget garments. Perfectly fine for many applications but not what you want for a premium next-to-skin piece.

Ring-spun + combed is the pairing you specify when quality matters. Open-end + carded is what you get when you don't specify anything.

Cotton Quality Grades | Staple Length

Cotton is graded by fiber (staple) length. Longer fibers make better yarn:

• Short staple (under 27mm): Basic cotton, used in low-cost items. Prone to pilling.
• Medium staple (27-32mm): Standard commodity cotton | most of the world's supply.
• Long staple (33-38mm): Premium cotton. Pima, Supima (American), and Egyptian cotton are examples. Softer, stronger, more expensive.
• Extra-long staple (over 38mm): Luxury cotton. Rare, expensive, used in premium sheeting and high-end fashion.

For streetwear brands, medium-to-long staple combed cotton is the sweet spot for quality and cost.

Organic vs Standard Cotton

Organic cotton is grown without synthetic pesticides, herbicides, or GMO seeds. Farmers use crop rotation and biological pest management. The cotton itself feels similar to conventional cotton | the difference is entirely in the growing method and the certification chain that proves it.

Two certifications matter here:

• OCS (Organic Content Standard): Certifies the organic content percentage in a finished garment. OCS 100 means 95%+ organic. OCS Blended means 5%+ organic.
• GOTS (Global Organic Textile Standard): More rigorous. Covers the entire supply chain | farm, ginning, spinning, weaving, dyeing, cut & sew. If you want to make premium organic claims, GOTS is the gold standard.

Organic cotton generally costs 10-25% more than conventional. Whether it's worth it depends on your positioning. Brands selling sustainability charge premiums that more than cover the fabric cost bump.

Recycled Cotton

Recycled cotton comes from post-industrial scraps (cut waste from factories) or post-consumer sources (used garments). The mechanical recycling process shortens fibers, so recycled cotton is usually blended with virgin cotton or polyester to maintain strength.

Certified under RCS (Recycled Claim Standard) or GRS (Global Recycled Standard), it's useful for sustainability-positioned brands. Just know you'll almost never see 100% recycled cotton fabric | it's typically 20-40% blends.

Regional Origins Matter

Cotton origin affects quality and pricing:

• Turkish cotton | Turkey is the world's 6th-largest cotton producer. Aegean cotton (from western Turkey) is known for long staples and softness. Widely used in Turkish garment manufacturing.
• American Pima/Supima | Extra-long staple, premium positioning, higher cost.
• Egyptian cotton | Historically the luxury benchmark, though much "Egyptian cotton" sold today isn't genuine.
• Indian cotton | Large supply, quality varies. Standard commodity option.
• Chinese cotton | Traceability concerns around Xinjiang have led many brands to specify "no Chinese cotton" in tech packs.

What to Specify in Your Tech Pack

Instead of just saying "100% cotton," specify:

• Fiber preparation: combed (recommended) or carded
• Spinning method: ring-spun (recommended) or open-end
• Origin restrictions if any (e.g., "no Chinese cotton")
• Organic certification if required (OCS or GOTS)
• Yarn count (e.g., 30/1 for tees, 20/1 for hoodies)
• GSM weight (grams per square meter of the finished fabric)

A tech pack line that reads "100% combed ring-spun Turkish cotton, 30/1, 220 GSM, OCS-certified" is dramatically clearer than "100% cotton" and gets you exactly what you specified.

"Cotton isn't cotton. The difference between a mediocre tee and a premium one is often in the yarn preparation, not the price tag."

How ICF Handles Cotton

Istanbul Clothing Factory works with combed ring-spun Turkish cotton by default. Organic (OCS-certified) and recycled (RCS-certified) options are available across our fabric library. We can also source Pima, Supima, or Egyptian cotton for premium positioning.
