In view of the problems of low strength, high hairiness, small elongation, high twist and high cost in warp knitting production using spun fiber yarns, the warping technology, high-speed production technology, clean production technology, intelligent production and fully formed warp knitting production technology in the production of spun yarn warp knitting were summarized in this paper. By summarizing the yarn quality requirements of spun yarn for warp knitting, including yarn breaking strength, surface hairiness and elongation properties, the problems and solutions of spun yarn warp knitting technology were further analyzed. Through introducing the application status and production situation of spun yarn warp knitted products in the fields of shirt fabrics, underwear fabrics, trousers and lace fabrics, the future development direction of spun yarn warp knitted technology was prospected, pointing out that the production technology of spun yarn warp knitting is gradually going towards specialization, high quality and functionality.
