What materials are used for the webbing?

Made from a variety of yarns made of narrow fabric or tubular fabric. With a wide variety of fabrics, it is widely used in apparel, shoe materials, luggage, industry, agriculture, military supplies, transportation and other industrial sectors. In the 30's, ribbons were produced by hand workshops and the raw materials were cotton and twine. After the founding of New China, the raw materials for webbing were gradually developed into nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming woven, knitted, and knitted three kinds of process technology. The fabric structure includes plain weave, twill weave, satin weave, jacquard, Bilayer, multi-layer, tubular and joint organization.

First, woven (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 iron wooden 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, the weaving method is 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 belt continuous dyeing and ironing machines, the processing of colored belts was changed from the traditional process of dyeing and weaving to the first weaving, the first weave, the first weaving, the post-stencil after-treatment, and the ribbon weaving technology became mechanized. 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 a seat belt for the Santana car was successfully implemented. After more than two years of research and organization, the product quality has reached QC49-92 and TL-VW470 standards.

Second, weaving (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 reciprocate the woven 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 varies from 9 to 100 spindles, depending on the equipment. The basic process flow for weaving is: bleaching and dyeing—weft-weaving—drop-cutting—packaging. Since 1960, several technical innovations have been carried out 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, or 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.

Third, knitting 70 years, knitting warp knitting, weft knitting technology, has been widely used in webbing. In 1973, the trial successfully produced a knitted nylon wide tight tape. In 1982, the introduction of the Italian crochet machine, advanced technology, wide variety of production, especially suitable for thin decorative belt fabrics, such as lace, elastic bands, window screening, decorative belts and so on. The basic process flow is: bleaching and dyeing - winding - weaving - ironing - packaging.

Before the 1970s, the fire hose blanks were woven with a flat weaving machine, and the diameter of the tube blanks was large and the yield was low. In the second half of 1974, the industry organization tube blank weaving research group adopted the warp and weft woven fabric according to the principle of knitting, relying on the circled yarn in the loop formation process, using the cylindrical and subsidence loops of the looped yarn, and the non-woven warp and weft yarns. Linked into a whole, and become lining weft-inserted tubular knitted fabrics, product coating water pipe and high-pressure fire hose technology level of production technology ranks first in the country.

Ribbon Classification 1) By Material: Nylon/Tedoron/PP Polypropylene/Acrylic/Cotton/Polyester/Gold/Silver Onion/Spandex/Rayon/Rayon, etc. Nylon and PP Ribbon Sorting: General Nylon Ribbon is Weaved First Dyeing, so the color of the yarn after slitting will cause the color of the white yarn to be uneven due to uneven dyeing, while the PP ribbon is dyed and rewoven first, so there will be no phenomenon that the yarn becomes white; compared with the nylon ribbon than the PP ribbon It is shiny and soft; it can also be distinguished by the chemical reaction of burning; the general price of nylon webbing is higher than that of PP webbing.

The Tedoron webbing is softer, and the non-glossy acrylic webbing is made of Tedolon and cotton. The price of the cotton webbing is generally higher.

2) According to the weaving method: There are three categories of plain weave, twill weave, satin weave and miscellaneous weave. (Plain/small corrugated/twill/secure webbing/hanging/beading/jacquard PP webbing can be divided into 900D/1200D/1600D according to the thickness of its yarn; at the same time we should pay attention to the thickness of the webbing, and the thickness also determines its unit price and toughness. degree.)

3) According to the width specifications: 10MM/12MM/15MM/20MM/25MM/30MM/32MM/38MM/50MM.

4) According to the nature of use: clothing ribbons, shoe ribbons, luggage ribbons, security ribbons, and other special ribbons.

5) According to the characteristics of the webbing itself: elastic webbing and rigid webbing (non-elastic webbing).
