In fact, ribbon is simply made of narrow fabric or tubular fabric with various yarns as raw materials, and has been widely used in many industrial sectors. So what is the development of webbing? Let's summarize the relevant knowledge for you. I hope it can help you.
Woven (woven)
Longitude and latitude interweave. After twisting, the yarn is warped into a bobbin (pan head), the weft is shaken into a winding, and the belt is woven on the loom. In the 1930s, it was used as webbing for hand-held wood loom and iron wood loom. In the early 1960s, the 1511 loom was converted into a webbing machine, which is still widely used. Due to the small width of the belt, the weaving methods are different, ranging from single strip, double strip and dozens of strips, from single layer to double layer.
In 1967, the shuttleless belt research group with workers as the main body of the industry successfully designed and manufactured a high-speed single shuttleless belt loom by itself, which realized that the ribbon did not need to be shuttled, shortened the process, small floor area and improved labor productivity, which was an innovation in the history of Chinese ribbon technology.
In the 1970s, due to the promotion of belt continuous dyeing and ironing machine, the processing of colored belt developed from the traditional process of dyeing first and then weaving to weaving first and then dyeing, weaving first and then bleaching, and ironing and then processing continuously. The webbing technology entered the ranks of mechanized mass production. In the early 1980s, the industry introduced Switzerland, Italy and the Federal Republic of Germany high-speed shuttleless belt looms, ironing machines, wrapping machines, warping machines, etc., and the belt technology entered a new stage of development.
The progress of webbing technology has brought about the upgrading of products. In 1979, the trial production of the first generation sd9-9 rubber ingot belt in China was successful, which ended the history of relying on import. In 1980, sd-81a and B rubber ingot belts were developed, which are soft, light, thin, firm, small elongation, small impact force and short and flat joints. At the beginning of 1990, the trial production of automobile safety belt for Santana car was successful. After more than two years of research and trial production, the product quality has reached qc49-92 and tl-vw470 standards.
Weaving (spindle weaving)
After the yarn is formed into a weft tube through the winding cylinder and weft winding, it is inserted on the fixed tooth seat of the knitting machine, and the weft tube rotates and moves along the 8-shaped track to pull the yarn to cross weave with each other. Usually, the number of spindles is even, the woven belt is tubular, the number of spindles is odd, and the woven belt is flat. The spindle weaving process has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment. The basic weaving process is: bleaching and dyeing, weft winding, weaving, falling machine, cutting and packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including enlarging the diameter of peach board, installing automatic stop device for broken rubber tendon, and changing iron ingot into nylon ingot. With the improvement of these equipment, the speed is increased to 160 ~ 190 rpm, the stand rate is doubled, and the product quality is greatly improved.
Weaving can not only weave belts, but also weave ropes. Tubular belt is a kind of braided rope. It is called rope or rope with a diameter of 1 ~ 4 mm. It is also called rope with a diameter greater than 4 mm. It is generally called cable or rope with a diameter greater than 40 mm. In 1989, the industry introduced Japanese eight strand cable production line equipment and produced polypropylene eight strand cable in the following year. The product won the national silver award.

In the 1970s, the technology of warp knitting and weft knitting has been widely used in webbing. In 1973, the trial production of knitted nylon wide belt was successful. In 1982, it began to introduce Italian crocheting machine with advanced technology and wide production varieties, especially suitable for thin decorative belt fabrics, such as lace, elastic belt, window screen, decorative belt, etc. The basic process flow is: bleaching and dyeing - winding - weaving - ironing - packaging.
Before the 1970s, the pipe blank of fire hose was woven with flat loom, with large diameter deformation and low output. In the second half of 1974, the industry organization tube blank weaving development group, according to the principle of knitting, adopted warp and weft shuttle weaving, relied on the circular yarn, and connected the non interlaced warp and weft into a whole by using the circular cylinder and settlement arc of the circular yarn in the process of circular yarn, so as to become a warp and weft lined tubular knitted fabric, The production technology level of plastic coated outlet pipe and high-pressure fire hose ranks first in the country.
