At present, the gauges of warp knitting machines are as high as E50. The distance between knitting needles has become smaller and the gap between yarns is smaller. The yarns are required to be thinner and have better evenness. Therefore, only finer yarns can adapt to the development of high gauges. Miao Xuhong believes that the demand for 10D~40D chemical fiber filaments will increase.
In addition to price, the competitive advantage of polyester fiber and natural fiber lies in its changeable style and plastic function. A representative of one company said that the future development space of polyester lies in differentiation and functionality. The pursuit of personalized clothing trends will bring opportunities to such companies. Research by Zhu Lijuan, a researcher at the National Textile Product Development Center, also shows that the popularity of polyester lies in its ability to adapt to changes in fashion trends.
Zhu Lijuan pointed out in the report “Interpretation of Fabric Trends and Forecast of Demand for Chemical Fiber Materials” that fabrics with high gloss, liquid light, matte, translucent and other technological senses, as well as 3D effects such as three-dimensionality, texture and wrinkles, will become A popular favorite for the current and future period. Polyester and polyester companies should improve the research and development and design of these products. Zhu Lijuan said that high-simulation polyester fibers such as cotton-like, wool-like and linen-like fibers, as well as fibers with functional functions such as health care and intelligence, will follow the development trend.
Professor Miao Xuhong of Jiangnan University also introduced in detail the development trends of knitting technology and knitted products and the demand for polyester materials. Specifically, the current gauges of warp knitting machines are as high as e50. The distance between knitting needles has become smaller, and the gap between yarns is smaller. The yarns are required to be thinner and have better evenness. Therefore, only finer yarns can adapt to high gauges. development. Miao Xuhong believes that the demand for 10d~40d chemical fiber filaments will increase.
In addition, all types of knitting machinery are developing at high speeds. The maximum speed of high-speed warp knitting machines reaches 4400r/min, and the speed of multi-bar jacquard warp knitting machines exceeds 1000r/min. Tension fluctuations are large during high-speed knitting, and the requirements for yarn mechanical properties are higher. high. Therefore, better quality raw materials can meet the needs of high-speed production.
In addition to important factors such as equipment that affect the development trend of chemical fiber products, the fashion trend of knitted products cannot be ignored. Miao Xuhong said that raw materials such as imitation cotton, imitation linen, imitation wool, imitation silk, and imitation leather can reduce raw material costs, reduce processing steps, and achieve high-speed production. They have already been used in warp-knitted casual men’s fabrics, polyester imitation leather coats, and polyester imitation cotton. Become popular on fabrics and other products.
Sports products with functions such as moisture absorption, perspiration, quick-drying, and warmth retention, and health-care products with antibacterial, deodorant, negative ion, far-infrared, and heating functions are also trends in market development.
