✅ There is only what’s most suitable for your needs

Choosing the wrong one can lead to:

• uncompetitive pricing

What Does “s” Mean in Cotton Combed?

yarn thickness (yarn count)

Common Misconception

Many people assume:

❌ 30s = lower quality

In reality:

⚠️ 30s is not worse — it simply serves a different purpose

Example:

• premium brands → 20s

• mass market → 30s

How to Choose the Right One

1. Know Your Target Market

• premium → 20s

• mid-market → 24s

• budget → 30s

2. Define Your Product Positioning

• thick & premium → 20s

• balanced → 24s

• light & affordable → 30s

3. Consider Usage

• hot outdoor use → 30s

• fashion / structured look → 20s or 24s

Relationship with GSM

👉 Important:

20s, 24s, and 30s are not the same as GSM

However:

⚠️ yarn thickness directly influences fabric weight (GSM)

Thicker yarn → heavier fabric → higher GSM

Finer yarn → lighter fabric → lower GSM

Common Industry Benchmarks

Yarn Type	Typical GSM
20s	± 190–200 gsm
24s	± 180–190 gsm
30s	± 150–160 gsm

👉 In simple terms:

• 20s → thick & heavy

• 24s → balanced

• 30s → lighter

Even with these benchmarks:

❗ GSM can still vary depending on knitting settings and finishing

But in practice:

👉 these ranges are considered safe and reliable production standards

Conclusion

There is no single “best” fabric.

The right choice depends on:

• your target market

• your product positioning

• your intended use
