Viscose, nylon, and imitation rabbit hair nylon blended raw materials are selected as outer fibers, and PBT filaments are used as core yarns; the pre-spinning process parameters are reasonably selected, a filament core-spun device is installed on the spinning frame, and the filament tension and spindle speed are optimized. , twist, equipment specifications, and other parameters; by strictly controlling the spinning process equipment and operation quality, and specially formulating quality control management methods and internal control quality standards, the imitation rabbit hair core spun yarn spun out has few defects and good quality. It is considered that the developed imitation rabbit core spun yarn not only overcomes the defects of imitation rabbit hair core spun yarn depilation and pilling, but also has the characteristics of soft, fluffy, and smooth rabbit hair yarn, and the quality index and appearance style meet the requirements of weaving.

　　Through market research, it is found that PBT core-spun yarn fabrics are relatively scarce in the market, users have demand in developing downstream high-end products, and the added value of shovel products is high. Therefore, we quickly organized and developed PBT filament core-spun yarn series products with a company. By transforming the existing ordinary ring spinning equipment, constantly exploring, improving the process, and accumulating production management experience, the current product quality has been recognized by the market, and established A set of core-spun yarn quality management systems.
