Recommended Polyester Fiber Blends for Yarn Production

Polyester fiber is the most widely used synthetic fiber in the global textile industry due to its high durability, cost-effectiveness, and excellent shape retention.

However, when used alone, it can lack the softness and breathability of natural fibers.

To overcome this, polyester is often blended with cotton, wool, or rayon to produce yarns with enhanced performance and feel.

So, what’s the optimal blend ratio of polyester for yarn production?

Let’s explore the most common combinations and their key features.

Cotton + Polyester Blend

The cotton and polyester blend is one of the most commercially successful combinations in the textile industry.

Here’s why:

1. Cost Competitiveness

   • 100% cotton yarn tends to have higher production costs and volatile prices. Blending with polyester stabilizes the price structure—ideal for mass production items like shirts, T-shirts, and uniforms.

     
     

2. Durability and Easy Maintenance

   • Polyester improves cotton's durability and wrinkle resistance.

   • It also enhances shape retention after washing and requires less ironing.

     
     

3. Improved Comfort

   • Cotton’s moisture absorption and breathability balance polyester’s shortcomings, making it comfortable for summer wear and bedding.

     
     

4. Market Acceptance

   • TC 65/35 (65% Polyester / 35% Cotton) is a global standard spec, widely adopted by OEM/ODM garment factories and home textile manufacturers.

Blend Ratio	Key Features	Common Applications
Polyester 65% / Cotton 35% (TC 65/35)	Durable, wrinkle-resistant, retains shape after wash	Uniforms, shirts, bedding
Polyester 50% / Cotton 50%	Balanced strength and comfort	T-shirts, sportswear
Polyester 20% / Cotton 80%	Emphasizes softness, moderate durability	Premium casualwear, luxury home textiles

Wool + Polyester Blend

Wool is known for its warmth and luxurious feel but comes with higher cost, lower durability, and complex care requirements.

Blending with polyester improves strength, shape retention, and price efficiency—allowing high-end fabrics to be mass-produced affordably.

That’s why this blend is widely used for suits, coats, and knitwear today.

Blend Ratio	Key Features	Common Applications
Polyester 55% / Wool 45%	Combines warmth with durability and affordability	Suits, coats, outerwear
Polyester 30% / Wool 70%	Preserves wool’s luxury feel while improving abrasion resistance	Premium knits, winter fashion

Rayon + Polyester Blend

Rayon has a silky soft touch and elegant sheen, making it a popular fashion fabric.

However, it has low strength and poor moisture resistance.

Blending with polyester improves durability and wrinkle resistance—perfect for dresses, blouses, and linings.

Blend Ratio	Key Features	Common Applications
Polyester 35~50% / Rayon 50~65%	Soft, shiny like silk + durable and wrinkle-resistant	Dresses, blouses, linings
