Five characteristics of aramid fiber
Aramid cloth, namely Kevlar cloth, aramid fiber cloth, aramid fabric, is a kind of fabric with insulation and heat preservation. It has a wide range of applications in industry and military protection. It has the following major characteristics:
1. Good mechanical properties Aramid is a flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc., with greater elongation, soft feel and good spinnability, and can Made into staple fibers of varying denier and length. In ordinary textile machinery, fibers and filaments are made into different yarns and woven into fabrics and non-woven fabrics. After finishing, it can meet the requirements of protective clothing in different fields.
2. Excellent flame retardancy and heat resistance. Meta-aramids have a limiting oxygen index (LOI) greater than 28 and therefore do not continue to burn when leaving the flame. The flame retardant performance of Newstar® meta-aramid depends on its own chemical structure, so it is a permanent flame retardant fiber that will not reduce or lose its flame retardant properties due to use time and washing time. Newstar® meta-aramid has good thermal stability, can be used continuously at 205°C, and can still maintain high strength at high temperatures above 205°C. Newstar® meta-aramid has a higher decomposition temperature and will not melt or melt. Melts under high temperature conditions. Carbonization only begins at temperatures above 370°C.
3. Stable chemical properties meta-aramid has excellent resistance to most chemicals, can resist most high-concentration inorganic acids, and has good alkali resistance at room temperature.
4. Radiation resistance meta-aramid has excellent radiation resistance. For example, under long-term exposure to 1.2×10-2 w/in2 ultraviolet rays and 1.72×108rads gamma rays, their intensity remains unchanged.
5. Durable meta-aramid offers excellent friction and chemical resistance. After 100 washes, the tear strength of fabrics treated with Newstar® meta-aramid can still reach more than 85% of the original strength.
