A cotton-polyester blend is a fabric made by combining cotton and polyester fibers. Manufacturers can vary the proportions of cotton and polyester or even blend with another fiber to achieve certain desirable characteristics.

Cotton and polyester are two popular fibers in the textile industry and are known for their seaming opposite qualities – one is natural and one is synthetic. In an attempt to create a material that combines all the benefits of each material and balances their unfavorable characteristics.

The mix of cotton and polyester brings out the best characteristics of each fiber. Cotton polyester blends are soft, breathable, moisture-absorbent like cotton, and at the same time, inherit the durability and wrinkle resistance from polyester.

Cotton-polyester blends are available in various ratios, each offering different characteristics in terms of comfort, durability, and performance.

The choice of blend ratio depends on the specific requirements of the application and the desired balance between the characteristics of cotton and polyester. For example, higher polyester percentages increase durability and wrinkle resistance but may reduce breathability and softness. Conversely, higher cotton percentages enhance softness and breathability but may decrease durability and wrinkle resistance.

Manufacturers select blend ratios based on the intended use of the fabric, considering factors such as comfort, performance, cost, and ease of care. It’s essential for consumers to be aware of these ratios when choosing clothing or textiles to ensure that the fabric meets their preferences and needs.

Here are some popular cotton-polyester blend ratios used in the textile industry:

50% Polyester, 50% Cotton

This is the most popular cotton polyester blend ratio for clothing. It offers a balanced blend that combines strengths from both fibers – the softness and breathability of cotton and the durability of polyester. 50% polyester/50% cotton fabrics are commonly used to make T-shirts, sweatshirts, and bed linens.

60% Polyester, 40% Cotton

The ratio of 60/40 between polyester and cotton creates a blend that balances durability and comfort, with a slight emphasis on durability. This cotton polyester blend, therefore, is often used in sportswear, work uniforms, or casual fashion.

65% Polyester, 35% Cotton

The higher percentage of polyester enhances durability, wrinkle resistance, and color retention.

Cotton’s share provides a softer feel and improved breathability which are absent in pure polyester fabrics. This blend leans more toward the durability side, which makes it suitable for casual wear, workwear, or uniforms.

65% Cotton, 35% Polyester

A 65% Cotton, 35% Polyester blend emphasizes the natural feel of cotton with added durability from polyester. This blend increased comfort and breathability while maintaining some wrinkle resistance. It is suitable for a wide variety of applications from casual wear to home textiles.

80% Cotton, 20% Polyester

The 80/20 cotton/polyester ratio strikes an ideal balance for clothing. Leggings, t-shirts, dresses, button-downs and most casual or athletic apparel can benefit.

Is 80 cotton 20 polyester good? Yes. An 80% cotton and 20% polyester blend is an excellent fabric for apparel. It combines the breathable softness of cotton with the durability and wrinkle resistance of polyester.

The high 80% proportion of cotton lends breathability, softness and airflow when woven into fabrics. This makes clothing comfortable against the skin. Cotton also absorbs small amounts of moisture, keeping light perspiration away from the body.

The 20% polyester adds wrinkle resistance, shape retention, stretch and quickness to dry. Clothes hold their fit and require less ironing after washing. The polyester also strengthens the material so seams and fabrics last longer.

Compared to 100% cotton, the blended fabric costs less to produce and stands up better to frequent wearing and cleaning.

This is also why cotton polyester blends are widely used for sportswear or work uniforms. They are comfortable enough to make the toughest workout or activities feel more tolerable, at the same time, they are robust and tough enough to endure the daily grind with ease.

Wrinkle Resistance

With pure cotton materials, you might have to make a tradeoff between feeling comfortable and looking sharp and flawless because cotton fabric tends to wrinkle easily. No matter how carefully you iron your cotton clothes, it will quickly crease and rumple in just a short time.

But when polyester enters the mix, its resilience and ability to fight off wrinkles will enhance the look of cotton polyester blends, and keep it smooth all day.

Easy Care

Have you ever wondered why cotton, despite all its great qualities, is not that popular in the modern apparel industry, especially for casual wear? One reason is that cotton is high-maintenance. But with cotton polyester blends, you can still enjoy the benefits of soft and breathable cotton but don’t have to pay too much attention to take care of the garment.

You can simply toss your cotton polyester pieces into the washing machine and it comes out just the same. That’s when you can feel the joy of having clothes that demand minimal fuss and still look fantastic!

Color Retention

Polyester in the blend acts as a keeper of colors, ensuring the fabric colors stay undamaged over time. Its ability to retain colors also makes it easy to care. Despite all the wear and tear, it can retain the original colors and look fresh like new.


Quality meets budget-friendly – that’s the magic of cotton-polyester blends. Polyesters are more affordable than cotton. By blending polyesters with cotton, you can lower the cost of fabric production. The higher the percentage of polyester, the more affordable the fabric is.

The lower price point for materials allows designers and brand owners to reduce the price of their products and increase their competitiveness.

Cons of Polyester blends

Potential Shrinkage

Imagine this: You find the perfect tee, it fits like a dream, and then it shrinks after a wash! The potential for shrinkage is a common con of cotton-polyester blends, especially if they’re not treated with care.

To avoid this nightmare, you can opt for blends with pre-shrunk or pre-treated labels. Always check the care instructions and, when in doubt, wash in cold water and air dry.

Impact on the Environment

Polyester, being a synthetic fiber derived from petrochemicals, takes a long long time to resolve. This material is not considered an environmentally friendly fabric.

Cotton polyester blends even though aren’t entirely green, it is still a better option compared to pure polyester materials.

One way you can lower the impact of cotton polyester blends on the environment is to choose blends made from recycled polyester or consider supporting sustainable fashion brands that prioritize environmental responsibility. When making mindful choices, you are casting a vote for a greener planet.

Tips for ironing:

  • Use low heat setting: Polyester is sensitive to high heat. Keep it cool to avoid a meltdown afterward. Set your iron to a low or medium heat setting only!
