Advantages and disadvantages of cotton, polyester, nylon and spandex carpets
Cotton: Advantages: sweat-absorbent, breathable, soft, anti-allergic, easy to clean, not prone to pilling. Natural fabric, comfortable to wear, breathable and warm. Disadvantages: easy to wrinkle, shrink, deform, fade, and have poor durability
Polyester:
1. High strength. The strength of short fiber is 2.6~5.7cN/dtex, and the strength of high-strength fiber is 5.6~?8.0cN/dtex. Due to its low hygroscopicity, its wet strength is basically the same as its dry strength. The impact resistance is 4 times higher than nylon and 20 times higher than viscose fiber.
2. Good elasticity. The elasticity is close to that of wool. When stretched by 5% to 6%, it can almost completely recover. The wrinkle resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22~141cN/dtex, which is 2~3 times higher than nylon.
3. Good heat resistance.
4. The surface of polyester is smooth, the internal molecules are tightly arranged, and there is a lack of hydrophilic structure between the molecules, so the moisture regain is very small and the moisture absorption performance is poor.
5. Good wear resistance. The wear resistance is second only to nylon, which has the best wear resistance, and is better than other natural fibers and synthetic fibers.
6. Good light resistance. Lightfastness is second only to acrylic.
7. Corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali and not afraid of mold, but hot alkali can cause it to decompose.
8. Poor stainability.
Nylon:
1. Strong and wear-resistant, ranking first among all fibers. Its wear resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber. Therefore, its durability is excellent.
2. Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under small external force, so the fabric is easy to wrinkle during wearing. ?Poor ventilation and breathability, easy to generate static electricity.
3. The hygroscopicity of nylon fabric is better than that of synthetic fiber fabrics, so clothing made of nylon is more comfortable to wear than polyester clothing. ?Has good moth resistance and corrosion resistance.
4. The heat resistance and light resistance are not good enough. The ironing temperature should be controlled below 140℃. During wearing and use, you must pay attention to the washing and maintenance conditions to avoid damaging the fabric.
5. Nylon fabric is a light fabric and is only listed after polypropylene and acrylic fabrics among synthetic fabrics. Therefore, it is suitable for making mountaineering clothing, winter clothing, etc.
Spandex (elastic fiber):
Advantages: The best elasticity, good light resistance, acid resistance, alkali resistance, and wear resistance. Disadvantages: The weakest strength and poor moisture absorption.
Uses: Spandex is widely used in underwear, women’s underwear, casual wear, sportswear, socks, pantyhose, bandages, etc. due to its characteristics. Mainly in the textile field, medical field, etc. Spandex is a highly elastic fiber necessary for high-performance clothing that pursues dynamics and convenience. Spandex can stretch 5-7 times longer than its original shape, so it is comfortable to wear, soft to the touch, wrinkle-free, and can always maintain its original contour
