Polyester blended yarns are widely used in the textile industry due to their excellent performance and diverse applications. Changes in the blending ratio directly affect the yarn's feel, which in turn influences the fabric's comfort and market competitiveness. Understanding the impact of different blending ratios on the feel of polyester blended yarns can help textile companies precisely adjust product formulas to meet diverse customer needs.
Basic Hand Characteristics of Polyester Fibers
Pure polyester fiber has high strength, good elasticity, and abrasion resistance, but it also has a stiff feel and lacks the softness and skin-friendly feel of natural fibers. Polyester fiber has a smooth surface and produces fabrics with good gloss, but poor breathability and moisture absorption, resulting in a relatively cool feel but not as soft. Polyester blends are often blended with natural fibers such as cotton and wool, or functional fibers such as acrylic and viscose to improve their feel.
Low Polyester Blends (Polyester Content 20%-40%)
Yarns with low polyester blends have a softer feel, similar to the feel of natural fibers. For example, when the cotton content is high, blended yarns exhibit good moisture absorption and breathability, resulting in a comfortable and skin-friendly feel. This blended yarn not only retains the softness and fineness of cotton but also enhances the abrasion resistance and wrinkle resistance of polyester, making it suitable for intimate apparel and home textiles.
At this ratio, the polyester fiber primarily contributes to the fabric's strength and durability without significantly altering the overall yarn feel. The overall feel is softer and fluffier, more comfortable than natural fibers, but its durability is lower than that of pure polyester.
Medium-Proportion Polyester Blend (40%-70% Polyester Content)
Medium-proportion blends are the most common polyester blends in the market. The yarn's feel begins to exhibit distinct synthetic characteristics. Increasing the polyester content significantly improves the yarn's elasticity and strength, making the fabric easier to maintain its shape and enhancing its wrinkle resistance.
However, as the polyester content increases, the yarn becomes stiffer and smoother, while the feel gradually becomes cooler and stiffer, and its softness decreases. The fabric's surface gloss improves, enhancing its visual appeal, but its moisture absorption and breathability decrease. This type of blend is suitable for sportswear, professional attire, and other garments requiring high durability. This blended yarn achieves a balance between functionality and comfort in terms of feel, meeting practical performance requirements while maintaining a certain level of comfort, adapting to diverse market demands.
High Polyester Blends (70%-90% Polyester Content)
High polyester blended yarns have a feel that strongly resembles synthetic fibers. They offer high strength, good elasticity, abrasion resistance, and wrinkle resistance. The fabric surface is smooth and has a certain sheen, but it feels hard, with significantly reduced softness and bulk.
Due to polyester's poor hygroscopicity, the fabric may feel dry and cool when worn, but it also lacks breathability and is prone to static electricity. High polyester blends are suitable for functional clothing, industrial fabrics, and outdoor apparel, where comfort requirements are lower but durability is extremely high.
The hard feel can be partially mitigated through yarn finishing processes such as softening and sanding, but the yarn's inherent stiffness remains noticeable, making the natural fiber's skin-friendly feel less apparent.
The difference in feel between polyester and different fiber blends: Polyester blended with cotton exhibits significantly better softness and moisture absorption than pure polyester, resulting in a natural and comfortable feel. When blended with viscose, the yarn exhibits a good luster and good softness, but its moisture absorption falls between that of pure polyester and cotton. When blended with wool, the yarn provides warmth and elasticity, but the characteristic roughness of wool fibers may affect the comfort experience for some consumers.
