What Is A Polyester Blend

A polyester blend is a fabric made by combining polyester fibers with natural fibers like cotton, wool, silk, etc. The most common polyester blends are poly-cotton, which mixes polyester and cotton, poly-linen, blending polyester and linen, and poly-wool, mixing polyester and wool fibers.

Polyester Blends

Polyester blends aim to get the best properties of both natural and synthetic fibers. For example, poly-cotton combines the durability and wrinkle resistance of polyester with the breathability and comfort of cotton. The percentage of polyester vs natural fiber can vary, like 50/50 poly-cotton or 65% polyester/35% cotton, depending on the desired qualities.

How are Polyester Blends Made?

There are two main ways polyester blends are made:

  • Blending fibers – The polyester and natural fibers are blended together before spinning into yarn. This creates a yarn with intimate mixing of the two fibers.
  • Blending yarns – Polyester and natural fiber yarns are made separately first, then woven or knitted together to make the fabric. This can allow different faces, like polyester on one side, and cotton on the other.

Blending at the fiber stage allows the most even mixing and consistent fabric properties. Yarn blending gives more flexibility in fabric finishes.

Key Benefits of Polyester Blends

Polyester blends aim to get the best of both synthetic and natural worlds. Key potential benefits include:

  • Strength – Polyester’s durability can reinforce and strengthen natural fibers prone to wear and tear.
  • Wrinkle resistance – Polyester’s shape retention reduces wrinkling of natural fabrics like linen or cotton.
  • Stretch and recovery – Adding stretchy polyester fibers to cotton improves elasticity.
  • Drying speed – Polyester’s quick drying counters natural fibers’ longer drying time.
  • Colorfastness – Polyester keeps colors vibrant compared to natural fabrics’ tendencies to fade.
  • Affordability – Adding polyester lowers cost compared to pricier natural fabrics.

Popular Uses of Polyester Blends

Thanks to their balanced properties, polyester blends have become go-to fabrics for many everyday uses:

  • Apparel – Affordable, durable, wrinkle-resistant clothing like polos, t-shirts, pants, and dresses.
  • Home textiles – Bedsheets, duvet covers, curtains with polyester’s easy care properties.
  • Athletic wear – Workout clothes benefit from polyester’s stretch, sweat-wicking, and quick drying.
  • Outdoor gear – Blends like poly-wool provide warmth plus polyester’s water resistance.

Key Disadvantages of Polyester Blends

While they aim for the best of both worlds, polyester blends can have drawbacks too:

  • Breathability – Natural fabrics like linen and cotton tend to breathe better than poly blends.
  • Environmental impact – Polyester’s plastic origins make it less eco-friendly than natural fabrics.
  • Sensitive skin – Some people find polyester irritates the skin compared to soft natural fibers.
  • Heat retention – Insulating natural fibers like wool lose some thermal properties blended with polyester.
  • Water absorption – Natural fiber’s absorbency is reduced when blended with hydrophobic polyester.


What are the most common polyester blends?

The most popular polyester blends are poly-cotton, poly-linen, and poly-wool. Poly-cotton combining polyester and cotton is the most widely used. It balances polyester’s easy care properties with cotton’s comfort. Poly-linen mixes the wrinkle resistance of polyester with linen’s natural feel. Poly-wool blends polyester’s durability with wool’s warmth.

How does polyester affect print quality?

Polyester’s ability to hold bright colors consistently makes printed colors more vibrant and accurate compared to natural fabrics. However, polyester’s lack of absorbency can limit some direct printing methods. Darker polyester fabric can also show through lighter printed colors. Proper fabric prep and print technique are needed for best print results.

What percentage of polyester is typical in blends?

Popular polyester blend ratios include 65% polyester/35% cotton for wrinkle-free polos and workwear, 50/50 poly/cotton for casual t-shirts, and 85% polyester/15% spandex for stretchy athletic wear. Adjusting percentages allows tuning fabric properties – higher polyester increases durability, wrinkle resistance, and drying speed.

Do polyester blends cost more than natural fabrics?

Poly-cotton blends tend to cost 20-50% less than premium natural fabrics like silk, linen, or high-end cotton. But blended fabrics can cost slightly more than basic cotton. The polyester component lowers cost, but blending processes add expense over pure synthetics or unblended natural fibers.

How can you reduce polyester blend shrinkage?

Pre-washing and garment pre-treatment relax fibers and reduce later shrinkage. Low-temperature washing, drying, and ironing also minimize shrinking forces on blended fabrics. Adding higher polyester percentages or using texturized polyester fibers also limits fabric shrinkage.


Polyester blends allow fabric engineers to fine-tune qualities by combining different percentages of polyester and natural fibers. This flexibility lets them balance important properties and meet the needs of different applications, from durable but comfortable t-shirts to moisture-wicking workout wear.

While they can’t completely escape polyester’s downsides like reduced breathability, polyester blends provide a versatile fabrication option with advantages over pure synthetics or natural fabrics alone. As fabric technology progresses, newer polyester types and advanced spinning techniques will likely further improve the capabilities of polyester blends.

I'm Emma, and I run Towels Edition, a website for fellow home goods enthusiasts who, like me, are passionate about textiles. After working in high-end retail, I was amazed by how little most people (myself included!) know about all the towel options out there.

I research and write all the content myself. Whether it's specialized towels like bar mops, Turkish cotton production methods, or comparing hair towel absorbency, I cover it. My goal is to share my knowledge and enthusiasm to help others.

Running Towels Edition allows me to constantly expand my own expertise too. I love learning about innovations in bamboo fabric or ideal bath towels. It's so rewarding to receive emails thanking me for recommendations that improved my readers' routines.

I want Towels Edition to be the ultimate online towel resource, making this overlooked necessity far more fascinating. My aim is to open people's eyes to how specialty towels can thoroughly enhance hygiene, cleaning, recreation and self-care.
