The polyamide fiber is modified by a variety of inorganic powder composite methods, so that the polyamide fiber has multiple composite functions such as antibacterial, deodorizing, far-infrared, negative ion emission, UV protection, moisture transmission and ventilation.

The successful development of "Jinkang Yarn" overcomes the contradiction between the content of multi-functional components and production efficiency, and endows polyamide fiber with excellent antibacterial and deodorant performance, excellent moisture conductivity and air permeability, high efficiency far infrared performance, excellent UV protection Performance and effective negative ion emission performance, to achieve the multi-functional composite of polyamide fiber, is a customer-centric, market-oriented product that emerged at the historic moment is a high-end polyamide that can meet customer needs and lead market consumption Fiber products.
