the characteristics of knitting
In the 1970s, knitting warp knitting and weft knitting technology has been widely used in webbing. In 1973, the trial production of knitted nylon wide tight belt was successful. In 1982, it began to introduce Italian crochet machines, with advanced technology and wide production varieties, especially suitable for thin decorative belt fabrics, such as lace, elastic belt, window screen, decorative belt and so on. The basic technological process is: bleaching and dyeing - winding - weaving - ironing - packaging.
Before the 1970s, the fire hose tube blank was woven with a flat loom, and the diameter of the tube blank was greatly deformed and the output was low. In the second half of 1974, the industry organized the tube blank weaving research and development team, according to the principle of knitting, using warp and weft weaving, relying on the loop-forming yarn in the loop-forming process, using the cylinder and sinker arc of the loop-forming yarn to separate the warp and weft yarns that are not interwoven. Linked into a whole, it becomes a warp-lined weft-inserted tubular knitted fabric, and the production technology level of the products' plastic-coated water pipes and high-pressure fire hoses ranks first in the country.
