Rangli poliester filament FDY xususiyatlari
1. High strength. The strength of short fiber is 2.6 ~ 5.7cN/dtex, and that of high strength fiber is 5.6 ~ 8.0cN/dtex. Because of its low hygroscopicity, its wet strength and drystrength are basically the same. Impact strength is 4 times higher than nylon, 20 times higher than viscose fiber.
2. Yaxshi elastiklik. Elastiklik junga yaqin va cho'zilish 5% ~ 6% bo'lganda deyarli to'liq tiklanishi mumkin. Burishishga chidamlilik boshqa tolalardan ustun turadi, ya'ni mato burishmaydi, yaxshi o'lchamli barqarorlikka ega. Elastiklik moduli 22 ~ 141cN/dtex ni tashkil qiladi, bu neylondan 2 ~ 3 baravar yuqori. Polyester mato yuqori mustahkamlik va elastiklikni tiklash qobiliyatiga ega, shuning uchun u bardoshli, ajinlarga chidamli va dazmollanmaydi.
3.Corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose. There are strong acid and alkaline resistance, anti - ultraviolet ability
