Aramid (Nomex is a kind of aramid) is a new type of high-tech synthetic fiber with ultra high strength, high modulus and high-temperature resistance, acid and alkali resistance, lightweight and insulation. Excellent performance in anti-aging, long life cycle, etc., widely used in composite materials, bulletproof products, building materials, special protective clothing, electronic equipment, etc.
1. Good mechanical properties
Meta-aramid is a flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc. It has high elongation, soft hand feel and good spinnability.
It can produce short fibers and filaments of different deniers and length. In the general textile machinery, different yarns are woven into fabrics, non-woven fabrics, and after finishing, to meet the requirements of protective clothing in different fields.
2. Excellent flame retardant, heat resistance
Meta-aramid has a Limiting Oxygen Index (LOI) greater than 28, so it does not continue to burn when it leaves the flame. The flame retardant properties of Newstar meta-aramids are determined by their chemical structure and are therefore a permanent flame retardant fiber that does not degrade or lose flame-retardant properties due to time of use and washing.
Newstar meta-aramid has excellent thermal stability and can be used continuously at 205 ° C. It can maintain high strength even at temperatures above 205 ° C. Newstar meta-aramid has a high decomposition temperature and does not melt or melt under high- temperature conditions. Charging starts when the temperature is higher than 370 °C.
3. High performance of anti- cut
For the aramid, the performance level can reach Europe standard 3 and ANSI 2.
4. Stable chemical properties
The meta-aramid has excellent resistance to most chemicals, and is resistant to most high-concentration inorganic acids, and has good alkali-resistance at room temperature.
5. Radiation resistance
The meta-aramid has excellent radiation resistance. For example, under the long-term irradiation of 1.2×10-2 w/in2 ultraviolet rays and 1.72×108 rads of γ-rays, the intensity remains unchanged.
The interfacial aramid has excellent anti-friction and chemical resistance. After 100 times of washing, the fabric treated with Newstar meta-aramid can still reach more than 85% of the original strength.
The above properties of aramid make it a good choice for the embryonic material of heat-resistant gloves. It also has excellent cutting performance and is a good choice for cut-resistant gloves. Aramid gloves combined with different materials to suit different working scenarios.
