Ribbon - Gift Ribbon Related Knowledge

A narrow webbing or tubular fabric is made from various yarns. There are many kinds of fabrics, which are widely used in various industrial sectors such as clothing, industry, agriculture, military demand, transportation and so on. In the 1930s, the webbing was produced by hand workshops, and the raw materials were cotton and twine. After the founding of New China, the raw materials for webbing gradually developed into nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major types of processing techniques: weaving, knitting, and knitting. The fabric structure has plain, twill, satin, jacquard, Double layer, multi-layer, tubular and joint organization.

 

First, weaving (woven)

Warp and weft. After the twisting, the yarn is made into a bobbin (pan head) by warping, and the weft yarn is twisted into a hazelnut to be weaved on a loom. In the 1930s, we hand-woven wood weaving machines and iron wood weaving machines. In the early 1960s, the 1511 looms were converted into webbing machines, which are still widely used. Because the width of the belt is small, the weaving method is different, and there are single, double, and dozens, and there are single layers and double layers.

In 1967, the industry-based shuttle less webbing research group successfully designed and manufactured its own high-speed single-strip shuttle less webbing machine, which realized that the webbing was not shuttled, and the process was shortened, the floor space was small, and labor productivity was improved. The pioneering work in the history of webbing.

 

In the 1970s, due to the promotion of the continuous dyeing and ironing machine for belts, the processing of colored belts was carried out from the traditional process of dyeing and weaving, to the first weaving and dyeing, the first weaving and then the weaving, the ironing treatment was continuous, and the webbing technology entered mechanization. The ranks of large production. In the early 1980s, the industry introduced foreign high-speed shuttle less looms, ironing joint machines, wrapping machines, warping machines, etc., and the ribbon technology entered a new stage of development.

 

Second, weaving (ingot weaving)

After the yarn is passed through the winding tube and the weft to form the weft tube, it is inserted into the fixed tooth holder of the knitting machine, and the weft tube is rotated along the 8-shaped rail to cross-weave the pulling yarns. Usually, the number of ingots is an even number, the tape is woven into a tubular shape, the number of ingots is an odd number, and the woven tape is in the form of a flat sheet. The ingot weaving process began to be applied in old China. The number of ingots varies from 9 to 100 spindles depending on the equipment. The basic process of weaving is: bleaching and dyeing - weaving - weaving - machine cutting and cutting - packaging. Since 1960, the knitting machine has undergone several technological innovations, mainly including the expansion of the diameter of the peach plate, the installation of the broken rubber automatic parking device, and the iron ingot to a nylon spindle. Improvements in these devices have resulted in a speed increase of 160 to 190 rpm, a doubling of the spectator rate and a significant increase in product quality.

Weaving not only weaves but also woven ropes. The tubular belt is a kind of braided rope, a rope or rope with a diameter of 1 to 4 cm, a rope having a diameter of more than 4 cm, and a diameter of more than 40 cm is generally called a cable or a cable. In 1989, the industry introduced Japan's eight-strand cable production line equipment, and produced eight-strand cable of polypropylene in the following year. The product won the National Silver Award.

 

Third, knitting

In the 1970s, warp knitting and weft knitting technology have been widely used in webbing. In 1973, a successful nylon knit band was successfully produced. In 1982, the introduction of the foreign crochet machine, advanced technology, wide variety of production, especially suitable for thin decorative belt fabrics, such as lace, elastic band, window screen, decorative belt and so on. The basic process flow is: bleaching dyeing - winding - weaving - ironing - packaging.

 

Before the 1970s, fire hose blanks were woven with flat looms, and the diameter of the blanks was large and the output was low. In the second half of 1974, the industry organization tube blank weaving research group, according to the principle of knitting, adopts warp and weft woven, relying on the looped yarn in the looping process, using the cylinder and the sinker loop of the looped yarn, the warp and weft yarns will be interwoven. Linked into a whole, and become a lining weft tubular knitted fabric, the production technology of plastic coated water pipes and high-pressure fire hoses ranks first in the country.
