How does the proportion of polyester spandex blended fabric affect the performance of polyester spandex fabric?

Polyester and Spandex blends are popular in the textile industry for their unique combination of properties. The performance of this blended fabric depends largely on the mixing ratio of the two fibers. The choice of this ratio directly affects the final properties of the fabric, including elasticity, abrasion resistance, breathability, wrinkle resistance and comfort.

elasticity
Spandex, as a highly elastic fiber, its biggest feature is that it can give polyester spandex fabric excellent stretch and recovery properties. In polyester-spandex blended fabrics, the higher the spandex content, the better the elasticity of the fabric. For garments that require a high degree of stretch and quick recovery, such as tights, sportswear and swimwear, increasing the proportion of spandex can significantly improve comfort and freedom of wear. However, excessive spandex content may also lead to increased fabric costs and may affect the overall stability of the fabric.

Wear resistance
Known for its excellent abrasion resistance, polyester is the material of choice for many durable garments. In blended fabrics, the higher the proportion of polyester, the more wear-resistant the fabric is. This means the garments will maintain their appearance and performance even after prolonged wear or frequent washing. For outdoor adventure, work clothes and other clothing that need to withstand harsh environmental tests, increasing the proportion of polyester is particularly important.

Breathability
Breathability is one of the important indicators of fabric comfort. Polyester itself has good breathability, but it is slightly less breathable than other natural fibers such as cotton or linen. The addition of spandex has a relatively small impact on breathability because it mainly exists as an ingredient to enhance elasticity. However, by adjusting the mixing ratio of polyester and spandex, combined with appropriate fabric structure and post-processing technology, the breathability of polyester spandex fabric can be improved while maintaining the elasticity to meet the wearing needs of different occasions.

Anti-wrinkle
Polyester is known for its good wrinkle resistance, which allows polyester-spandex blends to effectively resist wrinkle formation while remaining soft and elastic. In the mixing ratio, the higher polyester content helps to improve the anti-wrinkle performance of polyester spandex fabric, allowing clothes to quickly return to flatness and maintain a neat appearance even after being folded or pressed for a long time.

comfort
The comfort of polyester-spandex blended fabrics is affected by many factors, among which fiber ratio is one of the key. The appropriate proportion of spandex can give the fabric good fit and elasticity, improving wearing comfort. At the same time, although the hygroscopicity of polyester is not as good as that of some natural fibers, its moisture absorption and perspiration performance can be improved to a certain extent by improving spinning technology and post-processing processes, further improving the comfort of polyester spandex fabric.

The proportion of polyester-spandex blend fabric has a crucial impact on its performance. By adjusting the mixing ratio of the two fibers, the elasticity, wear resistance, breathability, wrinkle resistance and comfort of the fabric can be precisely controlled to meet different application scenarios and consumer needs. In actual production, manufacturers will choose the most appropriate fiber ratio to produce high-quality polyester-spandex blended fabrics based on factors such as product positioning, cost considerations, and market demand.
