🧵 Yarn Used for Denim, Fleece, and Terry Fabrics

Yarn plays a crucial role in determining the texture, comfort, and durability of any fabric. In the textile industry, every fabric type demands a specific yarn structure, count, and blend to achieve the desired performance. Among all fabric categories, Denim, Fleece, and Terry stand out due to their unique texture and end-use applications.

This article will discuss in detail what types of yarns are commonly used for Denim, Fleece, and Terry fabrics, why they are chosen, and how they affect the final fabric properties.

 

🟦 1. Yarn Used for Denim Fabrics

Denim is one of the most popular and versatile woven fabrics, primarily used in jeans, jackets, and casual wear. It is traditionally made using 100% cotton yarns, known for strength, breathability, and comfort. The yarns used in denim production are carefully selected to ensure the perfect balance of durability and style.

a. Type of Yarns in Denim

Denim fabric is produced using twill weave, where the warp yarns pass over multiple weft yarns, creating the signature diagonal rib pattern.
There are two major yarn directions in denim:

• Warp Yarns (Dyed Yarns):
  Warp yarns are usually ring-spun cotton yarns that provide excellent strength and elasticity. These yarns are dyed with indigo or sulfur dyes before weaving to give denim its deep blue or black shades.
• Weft Yarns (Undyed Yarns):
  Weft yarns are mostly open-end (OE) spun or carded cotton yarns, left undyed or in natural color. They help maintain fabric softness and flexibility.

b. Yarn Count and Twist

• Typical yarn counts for denim range from 6s to 20s Ne depending on fabric weight.
• High-twist yarns are preferred for the warp to resist abrasion during wear and washing.

c. Blended and Stretch Yarns

Modern denim production uses various blends to improve comfort and fit:

• Cotton/Spandex (98/2) – for stretch jeans and jeggings.
• Cotton/Polyester/Spandex (70/28/2) – for wrinkle resistance and shape retention.
• Recycled cotton or polyester yarns – for sustainable denim production.

d. Special Yarns for Premium Denim

• Slub yarns are used to create textured effects and vintage looks.
• Core-spun yarns with elastane cores give comfort stretch while maintaining the authentic denim look.

In summary, denim yarns must be strong, uniform, and dye-friendly, ensuring a balance of performance and fashion.

 

🩶 2. Yarn Used for Fleece Fabrics

Fleece fabrics are soft, thick, and warm knit fabrics used in sweatshirts, hoodies, jackets, and sportswear. The yarn type chosen for fleece affects softness, warmth, pilling resistance, and durability.

a. Common Fibers Used

The most common yarn for fleece fabrics is polyester, though cotton and blended yarns are also widely used.

• 100% Polyester Yarns:
  Provide excellent warmth, strength, and quick drying.
  Ideal for winter wear and sportswear.
• Cotton/Polyester Blends (50/50 or 60/40):
  Offer breathability, comfort, and better moisture management.
  Commonly used in casual fleece fabrics like hoodies and sweatpants.
• Recycled Polyester Yarns:
  Made from PET bottles, these yarns promote sustainability while maintaining high performance.

b. Yarn Type and Structure

Fleece fabrics are typically made with brushed or unbrushed loop structures on the inside to provide softness and insulation.

• Ring-spun yarns: Used for high-quality fleece with a smooth outer surface.
• Open-end yarns: Used in economical fleece for durability and bulk.
• Microfleece: Uses fine denier polyester yarns (below 1 denier) for a lightweight, smooth, and soft touch.

c. Functional Yarn Blends

• Polyester/Spandex: For stretchable athletic fleece.
• Cotton/Bamboo: For eco-friendly and anti-bacterial fleece.
• Recycled Polyester: For sustainable outdoor clothing lines.

d. Yarn Count Range

• Fleece yarns generally fall between 10s to 30s Ne, depending on fabric weight and knitting gauge.

Overall, fleece yarns are selected for softness, warmth, and stability, ensuring comfort for both sports and leisurewear.

 

🩵 3. Yarn Used for Terry Fabrics

Terry fabrics are known for their looped pile surface, which gives them high absorbency and softness. They are primarily used for towels, bathrobes, and sportswear. The yarn used in terry fabric must be soft, bulky, and absorbent.

a. Common Fiber Types

• 100% Cotton: The most widely used fiber due to its excellent moisture absorption and comfort.
• Cotton/Polyester Blends: Used to reduce drying time and enhance strength.
• Bamboo or Modal Blends: Provide extra softness, antibacterial properties, and eco-friendliness.

b. Yarn Type

• Ring-Spun Yarns: Produce high-quality, strong, and smooth terry fabrics.
• Combed Cotton Yarns: Used for luxury towels with improved softness and durability.
• Low-Twist or Zero-Twist Yarns: Provide a fluffy texture and maximum absorbency.
• Air-Spun Yarns: Used for lightweight, soft, and quick-drying terry products.

c. Yarn Count and Loop Design

• Typical yarn count: 10s to 20s Ne for both ground and pile yarns.
• Pile Yarns form the loops that provide absorbency.
• Ground Yarns (base yarns) give the structure and stability of the fabric.

d. Specialty Terry Yarns

• Bamboo-Cotton Yarns: Offer natural antibacterial properties.
• Egyptian or Pima Cotton Yarns: Long staple fibers ensure better softness, shine, and strength.
• Organic Cotton Yarns: Used for eco-conscious towel brands.

Terry fabric yarns must balance absorbency, strength, and softness, which depend heavily on yarn twist, count, and fiber type.

💡 5. Conclusion

The type of yarn used for denim, fleece, and terry fabrics determines how each fabric performs in terms of comfort, strength, and functionality.

• Denim yarns need to be strong and durable, often using ring-spun cotton or cotton-spandex blends for better performance.
• Fleece yarns emphasize softness and insulation, relying heavily on polyester and blended fibers.
• Terry yarns focus on absorbency and softness, typically made from low-twist cotton or bamboo yarns.

By understanding these yarn characteristics, textile engineers and merchandisers can develop fabrics that meet customer expectations in fashion, sportswear, and home textiles.
