Polyester yarn weather resistant, acid and alkali not, alkali resistance without acid polyamide silk, light fastness is not good, fiber strength will decline long exposure to the sun, the color yellow, polyamide fiber evanescent hues weaving feel is smooth, high gloss surface, the cloth in sportswear, swimwear, clothing, socks, polyester fiber is the world's largest output of synthetic fiber, polyester silk short silk and cotton, wool, linen, viscose blended yarn, such as the fabric maintained polyester yarn already fast, wear-resisting, crisp and easy collection, and both natural fiber, moisture absorption, heat preservation, less static electricity etc.
Polyester and polyamide similarities:
Are in the chemical fiber synthetic fiber, high strength, good abrasion resistance, poor permeability, wearing a sultry uncomfortable, easy to produce static electricity, widely used in clothing clothing and industrial USES.
The difference between the polyester and polyamide fiber:
Proportion is different, polyester silk fabric is not easy to wrinkle, and crisp, good dimensional stability, good conformal, polyamide fiber evanescent hues conformal sex is bad, no polyester yarn crisp, easy to deformation, polyester yarns in melting point 260 ℃, ironing temperature at 180 ℃, polyamide fiber evanescent hues heat resistance is not good enough, ironing temperature should be controlled under 140 ℃, low temperature resistant performance is good, polyamide fiber evanescent hues high intensity, good elastic resilience, good wear resistance, moisture absorption and dyeing are better than polyester yarn.
Polyamide, luster, fainter, bright colors and feel more hard, and the fabric will have crease folding, but can slowly recover.
Polyester: shine brighter, but not soft sex is very strong, has the effect of the flash, feel is smooth, good elasticity. Fabric will quickly recover after folding, no crease, it is not easy to break.
