Understanding 18/s, 20/s, 24/s, 26/s, and 28/s Yarn: A Complete Guide

In the textile industry, yarn count plays a vital role in determining the thickness, strength, softness, and end-use of a fabric. Among various counts, 18/s, 20/s, 24/s, 26/s, and 28/s yarns are some of the most commonly used in knitwear and woven fabric production. Let’s explore what these counts mean and how they differ from each other.

 

🧵 What Does “S” Mean in Yarn Count?

The “S” in yarn count refers to the English count system (Ne), which is used mainly for cotton yarn.

• It indicates how many hanks of 840 yards each make up one pound of yarn.
• In simple terms:
• Higher count (like 28/s) = finer, softer, and thinner yarn
• Lower count (like 18/s) = coarser, thicker, and heavier yarn

 

📘 Yarn Count Comparison Table

Yarn Count	Type	Thickness	Common Usage	Fabric Feel
18/s	Coarse	Thick	Fleece fabric, heavy jersey, hoodies	Rougher, durable
20/s	Medium Coarse	Slightly thick	T-shirts, polo shirts, sweatshirts	Soft but strong
24/s	Medium	Balanced thickness	Casual wear, knit tops, light tees	Smooth and soft
26/s	Medium Fine	Slightly fine	Premium T-shirts, fashion tops	Softer and lighter
28/s	Fine	Thin	Lightweight tees, baby wear, undergarments	Very soft and breathable

 

🔍 Characteristics and Applications

1. 18/s Yarn

• Nature: Coarser and thicker cotton yarn
• Applications: Commonly used in fleece, terry, and heavy knit fabrics
• Advantages: High durability and good warmth retention

2. 20/s Yarn

• Nature: Slightly finer than 18/s
• Applications: Basic T-shirts, polos, and sweatshirts
• Advantages: Good balance between comfort and strength

3. 24/s Yarn

• Nature: Medium count, commonly used in fashion T-shirts
• Applications: Light knitted garments, single jersey, and interlock fabrics
• Advantages: Soft hand feel, smooth surface, and good printability

4. 26/s Yarn

• Nature: Finer yarn with higher softness
• Applications: Used for premium T-shirts, tops, and sportswear
• Advantages: Lightweight and breathable, ideal for summer wear

5. 28/s Yarn

• Nature: Fine and delicate cotton yarn
• Applications: Infant wear, undergarments, and light summer tees
• Advantages: Extremely soft, smooth texture, and excellent drapability

 

⚙️ Key Factors Affecting Yarn Selection

When selecting between 18/s to 28/s yarn, manufacturers consider:

• Fabric GSM (weight)
• End-use of the garment
• Desired softness and appearance
• Cost efficiency

For instance, 18/s and 20/s yarns are ideal for heavy fabrics, while 24/s, 26/s, and 28/s are preferred for lightweight and soft garments.

 

🧶 Final Thoughts

Understanding yarn counts like 18/s, 20/s, 24/s, 26/s, and 28/s helps textile professionals choose the right yarn for specific fabric needs. Each count offers unique characteristics that influence fabric weight, comfort, and durability.

Whether you’re producing basic T-shirts or luxury fashion pieces, selecting the appropriate yarn count ensures both quality and performance in the final garment.
