Chemical short fibers are commonly known as "short fibers" or "short filaments". The product obtained by cutting chemical fibers into a certain length after forming. According to the difference in thickness and length, it can be pided into cotton short fibers (commonly known as "artificial cotton"), wool short fibers, and medium length short fibers. It can be spun pure on cotton, wool and other spinning machines, or blended with cotton, wool and other fibers. The quality evaluation items of chemical short fibers can be pided into two aspects: physical and mechanical properties and appearance defects. Physical and mechanical properties generally include: breaking strength, breaking elongation, fineness deviation, length deviation, super long fiber rate and double long fiber rate, curl number, moisture regain, etc. The classification of chemical short fibers is based on the inspection results of the physical and mechanical properties and appearance defects of the product, evaluated according to the specified requirements, and the lowest one is used as the grade of this batch of products.
