“Diamond wire” is a modified ultra-high molecular weight polyethylene fiber. By adding anti-cut particles in the production process of ultra-high molecular weight polyethylene fiber, the “diamond wire” fiber itself has both high anti-cut performance and high strength. Therefore, the fabric woven with “diamond wire” does not need to add auxiliary materials such as steel wire and glass fiber, and will also have high-level anti-cut performance and anti-wear performance, thus avoiding the above-mentioned shortcomings of glass fiber and steel wire.
