The history of the development of the needle loom

19 Aug 2022

The development of the webbing industry has continued to progress and develop in the long river of history. Because with the improvement of people's living standards, the requirements for the quality of life are also increasing. Ribbon is also developing continuously, and gradually there are single and double layers, weaving and dyeing, weaving and bleaching and other processes. The types of ribbons are becoming more and more abundant. needle looms bring great convenience to people's production. At the same time, the technology of needle looms It has also continued to improve and has made many pioneering breakthroughs.

The needle loom has greatly improved the efficiency of people's production of ribbons, and does not need to invest a lot of manpower and time. The needle loom reduces labor, increases the utilization rate of raw materials, saves costs and increases production capacity. Directly increases the value of the product.

Warp and weft interweaving. After twisting, the yarn is warped into a bobbin (pan head), the weft yarn is shaken and winded into a bun, and the tape is woven on the weaving loom. In the 1930s, weaving belts for hand-pulled wooden looms and iron-wood looms. In the early 1960s, the 1511 loom was converted into a needle loom, which is still widely used. Due to the small width of the machine belt, the weaving method is different from others, there are single layers, double layers, and dozens of different, there is a single layer, and there are double layers. In 1967, the worker-centered shuttleless webbing research group successfully designed and manufactured a high-speed single shuttleless webbing machine by itself. A pioneering work in the history of webbing. In the 1970s, due to the promotion of continuous dyeing and ironing machines for ribbon, the processing of colored tapes developed from the traditional process of dyeing and weaving to weaving and dyeing, weaving and bleaching, and ironing and processing. The ranks of mass production. In the early 1980s, the industry introduced high-speed shuttleless belt weaving machines, ironing machines, wrapping machines, warping machines, etc. from Switzerland, Italy, and the Federal Republic of Germany, and the technology of weaving has entered a new stage of development.

The progress of webbing technology has brought about the upgrading of products. In 1979, the first-generation SD9-9 rubber ingot belt was successfully trial-produced, which ended the history of relying on imports for rubber ingot belt products. In 1980, SD-81A and B-type rubber ingot belts were developed, which are soft, light, thin, firm, small in elongation, small in impact force, and short and flat in joints. At the beginning of 1990, the trial production of the car seat belt for the Santana car was successful. After more than two years to carry out research and organizing trial production.

Weaving (spin weaving)

After the yarn is wound through the winding and the weft to form a weft tube, it is inserted into the fixed tooth seat of the knitting machine.

The bobbin rotates along the figure-eight track to draw the yarns to cross each other. Usually, the number of spindles is even, the woven tape is tubular, the number of spindles is odd, and the woven tape is flat. The spindle weaving process has been applied since old China. The number of spindles varies from 9 to 100 spindles due to different equipment. The basic technological process of weaving is bleaching and dyeing - weft winding - weaving - dropping and cutting - packaging. Since 1960, several technological innovations have been carried out on the knitting machine, mainly including the enlargement of the diameter of the peach board, the installation of an automatic stop device for broken rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these types of equipment has increased the vehicle speed to 160-190 rpm, doubled the stand rate, and greatly improved the product quality. Weaving can not only weave ribbon but also weave rope. The tubular belt is a kind of braided rope. The diameter of 1-4 mm is called rope or rope. The diameter of more than 4 mm is also called rope. The diameter of more than 40 mm is generally called cable or cable. In 1989, the industry introduced Japanese eight-strand cable production line equipment and produced polypropylene eight-strand cable in the following year, and the product won the National Silver Award Knitting.

In the 1970s, knitting warp knitting and weft knitting technology have been widely used in webbing. In 1973, the trial production of knitted nylon wide tight belt was successful. In 1982, it began to introduce Italian crochet machines, with advanced technology and wide production varieties, especially suitable for thin decorative belt fabrics, such as lace, elastic belt, window screen, decorative belt, and so on. The basic technological process is bleaching and dyeing - winding - weaving - ironing - packaging.
