This is because the flame retardancy of fibers is generally measured and evaluated in the state of woven and knitted fabrics, but in woven fabrics and knitted fabrics, the flame retardancy varies depending on the number of twists, the thickness, the number of threads, etc. This is because the flame retardancy of can not be evaluated correctly.
