Brief Introduction Of Three Types Of Ribbon Technology

The webbing is made of narrow yarns or tubular fabrics made of various yarns.

It is widely used in various industries such as clothing, industry, agriculture, quartermaster, pportation and so on.

In 30s, the webbing was made by hand workshop, with cotton and linen as raw materials.

After the founding of new China, the material of ribbon was gradually developed into nylon, vinylon, polyester, polypropylene, spandex, viscose and so on, forming three kinds of technology, weaving, knitting and knitting. The fabric has plain weave, twill, satin, jacquard, double-layer, multi-layer, tubular and joint organization.

1. Woven (woven)

Warp and weft interweave.

After twisting, the yarn is made into warp (Pan Tou) by warping, and the weft yarn is twisted into a yarn, and the ribbon is woven on the loom.

In 30s, the webbing for hand loom and iron wood loom.

In the early 60s, 1511 looms were converted into ribbon looms, which are still widely used.

Because the width of the belt is small and the weaving way is different, there are single, double, and dozens of pieces.

In 1967, the research team of the shuttleless weaving band, which is mainly workmen oriented, successfully designed and manufactured high-speed single shuttleless loom belt machine successfully. It realized weaving without shuttle, and shortened the process, occupied a small area and increased productivity. It was a pioneering work in the history of Chinese weaving technology.

In 70s, due to the promotion of the continuous dyeing and finishing machine, the processing of colored ribbons was developed from the traditional dyeing and weaving process to the first weaving and dyeing process, after weaving and then drifting, and after continuous treatment, the weaving technology into the ranks of mechanized production.

In the early 80s, the industry introduced Switzerland, Italy, the Federal Republic of Germany high-speed shuttleless looms, ironing machines, wrapping machines, warping machines, weaving technology into a new stage of development.

The progress of ribbon technology has brought about upgrading and upgrading of products.

In 1979, the trial production of the first generation of SD9-9 rubber ingot in China was successful, and the history of rubber spindle products ended with dependence on imports.

In 1980, SD-81A and B rubber spindles were developed. They are soft, light, thin, firm, small in elongation, small in impact force, and short and smooth in joints.

Two, knitting (ingots)

After the warp tube and winding weft forms the weft pipe, it is inserted on the fixed tooth base of the braiding machine, and the weft tube moves along the 8 character track, and the traction yarn intersects and weaves.

Usually, the number of ingot is even, and the tapes are tubular and the number of ingot is odd. The tapes woven are flat.

Ingot weaving technology has been applied in old China. The number of ingot is generally different from that of 9~100 spindles. The basic technological process of weaving is: bleaching, dyeing, winding, weaving, cutting and packaging.

Since 1960, many technical innovations have been made to the braiding machine, mainly including the enlargement of the diameter of the peach plate, the installation of the automatic stop device of the rubber band, and the change of the iron ingot into a nylon spindle.

The improvements on these devices have speeded up the speed to 160~190 rpm, and the stand rate has doubled, and the quality of the products has been greatly improved.

Weaving can not only weave, but also weave.

Tubular belt is a kind of braided rope. It is called rope or rope line with a diameter of 1~4 cm. The diameter is more than 4 centimeters. It is also called rope, and the diameter is more than 40 centimeters.

In 1989, the industry introduced the Japanese eight strand cable production line equipment, produced the polypropylene eight strand cable in the following year, the product has won the national silver award.

Three, knitting

In 70s, knitting warp knitting and weft knitting technology have been widely used in ribbon weaving.

In 1973, the knitted nylon band was successfully produced.

In 1982, the Italy crochet machine was introduced, with advanced technology and wide variety of production. It is especially suitable for thin decorative fabrics such as floral, elastic belts, window screens and decorative belts.

The basic process flow is: bleaching, dyeing, winding - weaving - ironing - packaging.

Before 70s, the hose of fire hose was woven by flat loom, and the diameter of tube blank was large and the output was low.

In the second half of 1974, the development organization of tube weaving and weaving industry was based on industry organization.

The principle of warp and weft weaving is to use warp and weft knitted fabrics to make the circular weft yarn and weft yarn join together into a whole in the process of forming the ring yarn, and become the whole production technology level of lining the weft knitted fabric, lining the water outlet pipe and the high pressure fire hose.
