Performance characteristics of polyester fiber


As a new type of differentiated fiber material, polyester fiber has the characteristics of high strength, large modulus, small elongation, and good dimensional stability. The fiber has a soft texture, good cohesion, soft luster, and has a certain core warming effect. Polyester has poor hygroscopicity. Under normal atmospheric conditions, the moisture regain rate is only about 0.4%. Therefore, pure polyester fabrics have a stuffy feeling when worn, but their fabrics are easy to wash and dry, and have the reputation of "washable and wearable". Polyester has a higher modulus, second only to hemp fiber, and excellent elasticity, so the fabric is stiff, wrinkle-resistant, stable in size, and good in shape retention. Polyester has excellent abrasion resistance, second only to nylon, but it is easy to fluff and pilling, and the hair balls are not easy to fall off.



Performance characteristics of cotton fiber


The cross section of cotton fiber is irregular waist round with a cavity inside; one longitudinal end is a closed tubular cell, the middle is thicker, and the ends are thinner. Natural crimp is a unique morphological feature of cotton fiber. Cotton fiber is alkali-resistant and acid-resistant, and has strong absorption. The moisture regain rate of cotton fiber in the standard state is 7% to 8%, and its wet strength is greater than the dry strength ratio of 1.1 to 1.15. Cotton fiber is treated at a high temperature of 10°C for 8 hours, and the strength is not affected. Cotton fiber decomposes at 150°C and burns at 320°C. The specific resistance of cotton fiber is low, and it is not easy to generate static electricity during processing and use.


Advantages of cotton-polyester blending


It not only embodies the style of polyester and cotton but also has the advantages of cotton fabric. It has good elasticity and abrasion resistance in dry and wet conditions, stable size, low shrinkage, and has the characteristics of tall and straight, not easy to wrinkle, easy to wash, and quick-drying. . Moreover, the gloss is bright, smooth to the touch, crisp, with a certain degree of elasticity, the crease is not obvious after rubbing, and the recovery is faster. But the same inherited the shortcomings of chemical fiber: easy to fluff and ball up at the friction place. The polyester-cotton blended fabric feels thick, soft, and comfortable to wear. It will not be deformed, pleated, or shrink when washed.
