Woven (woven) warp and weft interwoven. and twist after the yarn through the whole warp into a cheese (pan head), weft roll into a fork, weaving on the loom. 30 's, for hand-pulled wood loom, ironwood loom weaving belt. In the early 60, 1511 loom was converted into ribbon machine, which is still widely used.
Because the belt width is small, the weaving way is different, has the single, the double, dozens of different, has the Single-layer, also has the double layer.
1967, the industry to workers as the mainstay of the Non-woven Ribbon Research Group, the successful design of their own high-speed single shuttle-free weaving machine, to achieve the weaving belt without shuttle, and shorten the process, covers a small area, labor productivity, is the history of China's ribbon technology pioneering. In the 70 's, because the belt continuous dyeing ironing machine promotion, the processing of colored tapes, from the first dyeing and weaving of the traditional process, developed to first dyed after dyeing, first weaving after bleaching, ironing after the treatment of continuous, ribbon technology into the ranks of mechanized production.
In the early 80, the industry introduced Switzerland, Italy, the Federal Republic of Germany high-speed shuttle-free weaving machine, ironing machine, wrapped wire machines, warping machines and so on, ribbon technology into a new stage of development. The progress of ribbon technology brings about the upgrading of products. 1979, the first generation of domestic sd9-9-type rubber spindle belt trial production success, so that the rubber ingots with products to end dependence on the history of imports. 1980, also developed sd-81a, B-type rubber belt, with soft, light, thin, prison, small elongation, small impact, short and flat joints. At the beginning of 1990, the automobile seat belts for Santana car were successfully manufactured.
After more than two years of time to carry out research, tissue trial, product quality to meet qc49-92 and tl-vw470 standards.
Weaving (spindle weave) After the Yarn meridian Tube, the weft winding forms the weft tube, inserts in the knitting machine's fixed tooth seat, the weft tube moves along the 8 shape orbit to rotate, pulls the yarn to cross weaves mutually. The usual number of spindles is even, woven into a tubular string, the number of spindles is odd, woven into a flat piece of tape. Spindle weaving technology in the old China began to apply, the number of spindles due to different equipment, generally 9~100 ingots, weaving the basic process is: bleaching and dyeing-weft-weaving-drop machine open shear-packaging. 1960, the weaving machine for a number of technical innovations, the main peach plate diameter amplification, installation of broken rubber automatic parking device, iron ingots changed to nylon spindle.
The improvement of these equipments makes the speed increase to 160~190 turn/cent, the stand rate increases one times, the product quality is greatly improved. Weaving not only webbing, but also weaving rope.
Tubular Band is a braided rope, the diameter of the 1~4 mm rope or rope line, more than 4 mm in diameter, also known as rope, diameter greater than 40 mm is generally called cable or cable.
Knitting 70 's, knitted warp knitting, weft knitting technology, has been widely used in weaving belt. 1973, the successful trial of knitted nylon wide tight belt. 1982, the beginning of the introduction of Italian crochet machine, advanced technology, the production of a wide range of special adaptation to thin decorative fabrics such as lace, elastic band, window screens, decorative belts.
The basic process is: bleaching and dyeing-winding-weaving-ironing-packaging. Before the 70 's, the fire hose was woven with a flat loom, and the diameter of the pipe billet was large and the output was low. In the second half of 1974, the industry organization Tube billet weaving Development Group, according to the principle of knitting, warp and weft weaving, depending on the spinning yarn in the circle process, the use of the circular yarn of the cylinder and the settlement arc, will not interwoven yarn and weft to form a whole, and become lined with weft-lined knitted fabric,
Products coated pipe and high-pressure fire water belt production technology level of the national crown.
