The Development of Woven
Interlaced with latitude and longitude. After the yarn is twisted, the yarn is made into a bobbin (pan head), the weft yarn is rolled into a braid, and the yarn is woven on the loom. In the 30's, wooden looms and ironwood looms were hand-drawn. In the early 1960s, the 1511 looms were converted into webbing machines and are still widely used. Because the width of the tape is small, weaving methods are not the same. There are single, double, dozens, single and double layers. In 1967, the industry-based research group of shuttleless ribbons successfully designed and manufactured its own high-speed single shuttleless webbing machine. It achieved no need for shuttlecock, shortened the process, occupied a small area, and improved labor productivity. It was China. The pioneering work in the history of webbing technology. In the 1970s, due to the promotion of the continuous dyeing and ironing machine for belts, the processing of colored tapes, from the traditional process of dyeing and reweaving, to the first weaving, dyeing, weaving, weaving, continuous treatment after ironing, ribbon weaving technology into mechanization Large production ranks. In the early 1980s, the industry introduced the high-speed shuttleless webbing machines, ironing machines, wrapping machines, and warping machines in Switzerland, Italy, and the Federal Republic of Germany. The webbing technology entered a new stage of development. The progress of webbing technology has brought about the upgrading of products. In 1979, the successful trial production of the first generation of SD9-9 rubber spindles in China made rubber strips with a history of dependence on imports. In 1980, SD-81A and B-type rubber spindle tapes were also developed, which are characterized by softness, lightness, thinness, firmness, small elongation, low impact force, and short and smooth joints. In early 1990, a successful trial of the safety belt for the Santana car was successfully completed. After more than two years of research and organization, the product quality has reached QC49-92 and TL-VW470 standards.
Atlas knitting (ingot weaving). After the yarn warp tube and the weft yarn form a weft thread tube, the weft thread tube is inserted into the fixed tooth holder of the knitting machine, and the weft yarn tube is circulated and moved along the figure-shaped track to interweave the traction yarns. Usually the number of spindles is even, the tape is woven into a tube, the number of spindles is odd, and the woven tape is flat. Ingot weaving technology began to be applied in old China, and the number of spindles varied from 9 to 100 spindles for different equipment. The basic process flow for weaving was: bleaching and dyeing—weft-weaving—drop-cutting—packaging. Since 1960, several technological innovations have been performed on the braiding machine, mainly including enlargement of the diameter of the peach plate, installation of an automatic stopping device for the rubber band, and change of the iron bar to a nylon spindle. Improvements on these devices have led to a speed increase of 160 to 190 rpm, a doubling of the stand-out rate, and a significant increase in product quality. Weave not only weave but also woven rope. A tubular tape is a type of braided rope, a weighed rope or cord having a diameter of 1 to 4 centimeters, a rope having a diameter of more than 4 centimeters and a rope having a diameter of more than 40 centimeters, generally called a cable or a cable. In 1989, the industry introduced Japan's eight-strand cable production line equipment, and in the following year produced eight strands of polypropylene cable, which won the National Silver Award.
