1. Woven yarn (now mostly used in arrow looms or air jet looms) refers to the yarn used to process woven fabrics, which is divided into warp yarn and weft yarn. Warp yarn is used as the longitudinal yarn of fabric. In order to ensure the quality of cloth surface and improve production efficiency, the weaving process requires high strength and good wear resistance. The weft yarn is used as the transverse yarn of the fabric, which can meet the characteristics of soft cloth surface quality.

2. Knitting yarn Knitting yarn is the yarn used for knitted fabrics. The cloth surface shall be smooth and soft. The yarn quality shall be good. According to experience in the procurement process, one of the main indicators for reference is yarn twist. The twist coefficient of warp for weaving is generally about 400. The twist coefficient of woven weft yarn and knitting yarn is generally about 350. Net twist factor/tex.
