Fiber refers to a substance composed of continuous or discontinuous filaments. In animals and plants, fiber plays an important role in holding tissues together. Fibers are widely used and can be woven into thin threads, threads and hemp ropes. They can also be woven into fiber layers when making paper or weaving felts. They are also commonly used to make other materials and form composite materials with other materials. Kebiao Testing has many years of experience in fiber testing and analysis. It is an authoritative third-party testing agency recognized by the country. Based on the testing and analysis results, Kebiao Testing can issue authoritative CMA, CNAS qualification certification, and nationally recognized test reports and analysis reports. Testing products: natural fibers: plant fibers, animal fibers, mineral fibers, etc.; chemical fibers: man-made fibers, synthetic fibers, inorganic fibers, etc.
1. Man-made fibers: viscose fiber, acetate fiber, cupro Fiber, regenerated cellulose fiber, regenerated protein fiber, regenerated starch fiber, regenerated synthetic fiber.
2. Synthetic fibers: polyester fiber (polyester), polyamide fiber (nylon or nylon), polyvinyl alcohol fiber (vinylon), polyacrylonitrile fiber (acrylic fiber), polypropylene fiber (polypropylene) , polyvinyl chloride fiber (vinyl chloride), etc.
