Nylon multifilament varieties (line), polyester, polypropylene filament and other products can be used with two synthetic materials since the beginning, the outer layer of the composite production, to meet the special needs of users. The product uses the latest technology, to reduce the fiber material in the production process of a strong self-consumption, increasing inner and outer rope yarn synchronization. Its powerful than similar products increased by 10%, wear resistance increased, elongation decreased, floating and so on. It is the introduction of international advanced technology research and development, high-tech products and patented product.
