Historical development of textile machinery
The advent of man-made fibers at the end of the 19th century broadened the field of textile machinery and added a category of chemical fiber machinery. The demand for synthetic fibers has increased, and the expansion of synthetic fiber spinning equipment has been promoted (spinning screw diameters up to 200 mm, daily production of single spinning machines to 100 tons) and high speed (spinning speeds of 3,000 to 4,000 meters). / points) direction development. In the fastest growing countries in the world's synthetic fiber industry, equipment has been updated once in five to six years, and the number of machines has doubled in 10 years. In the past 20 years, the spinning and weaving equipment has made many local improvements to adapt to chemical fiber pure spinning or blending with natural fibers, such as expanding the range of suitable fiber length of the drafting mechanism and eliminating static electricity on the fiber. In the dyeing and finishing, high temperature and high pressure dyeing equipment, heat setting equipment, resin finishing equipment and loose finishing equipment have been developed.
Non-woven fabrics are textiles made from textile fibers by bonding, fusion or other chemical or mechanical methods. This kind of textile is not a traditional spinning, weaving or knitting process, also called non-woven fabric, non-woven fabric.
