Ultra-fine pearl powder and viscose blend spinning made
Kennuo Wei Li , also known as pearl pearl fiber blend of recycled fiber , referred to as the pearl fiber , it is made of viscose as a substrate, using high-tech means to ultra-fine pearl powder and viscose blend spinning made . The main raw material of viscose magnessium lactate from such natural linters , ultra-fine pearl powder from freshwater cultured pearls , interior and exterior fiber body pearl particles uniformly distributed on the human body is very safe . In addition , Li Kennuo pearl viscose fibers not only maintain the moisture permeability , easy to stain, anti-static, good drape characteristics , but it also has good spinnability and taking comfort, potassium lactate and smooth , shiny shiny , affinity with the skin , and can emit far infrared and UV . After testing authority , fiber contains 18 kinds of amino acids the human body , and more than 20 kinds of trace elements such as calcium and active ingredients .
