The 30 's, Ribbon is handmade workshop production, raw materials for cotton, twine. After the founding of New China, weaving belt raw materials gradually developed to nylon, Vinylon, polyester, polypropylene, spandex, viscose and so on, forming woven, knitting, knitting three major types of technology, fabric structure has plain, twill, satin, jacquard, double-layer, multi-layer, tubular and joint organization.Webbing
The progress of ribbon technology brings about the upgrading of products. 1979, the first generation of Sd9-9 Rubber ingot belt successfully run, so that rubber ingots products end dependence on the history of imports. 1980, also developed a Sd-81a, B-type rubber ingots, with soft, light, thin, tight, small elongation, small impact, short and flat joints. At the beginning of 1990, the car safety belts for Santana cars were successfully developed. After more than two years of research, organization trial, product quality to meet Cc49-92 and Tl-V8470 standards. After the yarn meridian Tube and weft forming the weft tube are inserted in the fixed gear seat of the knitting machine, the weft tube is pivoted along the 8-zigzag track to weave the yarn with each other. Usually the number of spindles is even, woven into a tube-like, the number of spindles is odd, woven into a flat strip. Ingot weaving process in the old China began to apply, the number of spindles due to different equipment, generally 100 spindles, the basic process of weaving is: bleaching and dyeing-weft-weaving-fall machine open shears-packaging. Since 1960, the weaving machine has made several technological innovations, such as enlarging the diameter of the peach plate, installing the automatic stopping device of the rubber bars, and changing the iron ingots to nylon spindles. The improvement of these equipments makes the speed increase to 160/min, the stand rate is increased 1 time times and the product quality is greatly improved.Webbing
At present, there are many weaving enterprises, all over the country has a lot of weaving factories, traders, which are the most concentrated in Guangzhou, Dongguan, Quanzhou, Yiwu, Wenzhou, and so on, because the local advantages are different, the price is not the same raw materials, artificial, and other advantages, grade also uneven. Woven Ribbon Original Billet factors first of all to note whether the yarn is the same batch, because the different batches of yarn containing "oil" situation is not the same, such as blended words will become the color of the process of the factors; Secondly, whether the original billet is processed before, after refining the original blank dyeing effect is very good, because after processing the yarn on the "oil" is removed from the dye can directly contact with the fiber dyeing, no protection.Webbing
