Workwear fabric nylon polyester which is better? What are the properties of polyester fabric overalls? Polyester Information Network will take you one or two.
1. High intensity. The short-fiber strength of custom-made overalls is 2.6-5.7 cN/dtex, and the high-strength fiber is 5.6-8.0 cN/dtex. Due to its low hygroscopicity, its wet strength is essentially the same as the dry strength. The impact strength is 4 times higher than that of nylon and 20 times higher than viscose.
2, good flexibility. The elasticity is close to that of wool, and when it is stretched by 5% to 6%, it can be almost completely recovered. The wrinkle resistance is superior to other fibers, that is, the fabric is not wrinkled, and the dimensional stability is good. The modulus of elasticity is 22 to 141 cN/dtex, which is 2 to 3 times higher than that of nylon.
3. Good heat resistance.
4. The surface of the polyester is smooth, the internal molecules are closely arranged, and the hydrophilic structure is lacking between the molecules, so the moisture regain is small and the moisture absorption performance is poor.
5, good wear resistance. Wear resistance is second only to nylon with the best abrasion resistance, better than other natural and synthetic fibers.
6, good light resistance. Lightfastness is second only to acrylic.
7, corrosion resistance. It is resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can decompose it.
8. Dyeing is poor.
