A variety of yarns as raw material made of fabric or narrow tube-like fabric. Fabric with a wide variety, are widely used in apparel, industrial, agricultural, military, transportation and other sectors. 30 years, are hand-weaving workshop production, raw materials as cotton, linen threads. After the founding of new China, the progressive development of ribbon to use raw materials of nylon, PVA, polyester, polypropylene, spandex, viscose and so on, the formation of weaving, braiding, knitting the three types of technology, plain weave fabric structure, twill, satin, jacquard, double, multi-layered, tubular and joint organizations.

A woven (woven)

Jingwei intertwined. And after twisting yarn warping caused by the cheese (pan head), roll into a twist weft son, in the ribbon loom. 30 years, for the wooden hand looms, iron wooden weaving loom. In the early 60 to 1511 converted into ribbon loom machine, is still widely used. Due to the small band width, weaving a different way, there are single, double, the number ranging from 10, a single-layer, there are double-decker.

In 1967, industry workers for the non-woven with the main research group, has successfully designed and produced their own high-speed non-woven with a single machine, do not achieve the ribbon spindle, and to shorten the process, covers an area of small, labor productivity It is the history of the Chinese Ribbon initiative process.

70 years, as a result of ironing machine tape for the promotion of staining, non-ferrous metals processing scallops, after staining by the first of the traditional weaving techniques, the development of the first post-weaving dyeing, weaving after the first drift, ironing for post-processing, and weaving technology into the the ranks of large-scale production mechanization. The early 80s, trade, Switzerland, Italy, the Federal Republic of Germany with high-speed non-woven machine, ironing machine, wrapped-ray machine, warping machine and so on, weaving technology into the new stage of development.
 
Ribbon technology advances, brought about by the upgrading of products. In 1979, the first generation of domestic SD9-9-type rubber spindles with the success of trial production, so that the end products of rubber spindles with the history of dependence on imports. In 1980, they developed SD-81A, B-type rubber spindles with a soft, light, thin, firm, small elongation, impact of small, short and smooth joint characteristics. Early in 1990 for the Santana sedan cars with seat belts supporting the successful trial. Also, as more than two years to carry out research, trial organization, product quality and QC49-92 standard TL-VW470.

Second, knitting (tablet weaving)

Meridian yarn extinguishers, vol Wei after the formation of parallel tubes, inserted in the weaving machine teeth fixed seat, filling tube 8-shaped track along the rotary movement to traction knitting yarns intersect. Usually the number of spindles is even, for the tubular woven ribbon, for the odd number of spindles, woven into a flat sheet for the scallops. Weaving spindles in old China started to process applications, the number of spindles of different equipment, typically ranging from 9 to 100, weaving the basic process for: dyeing - Volume Wei - Weaving - open cut off machine - packaging. Began in 1960, a number of the knitting machine of technological innovation, mainly to enlarge the diameter of peach board, install automatic stopping device broken rubber band, nylon replaced ingot iron spindles. Improvement of these devices, so that the speed increased to 160 ~ 190 r / min, stands to double the rate of product quality greatly improved.

Ribbon weaving not only, but also woven rope. Tubular belt is a woven rope, the diameter of 1 to 4 centimeters, said rope or rope lines, more than 4 cm in diameter, also known as rope, more than 40 cm in diameter is commonly referred to as rope or cable. In 1989, the cable industry stereotyped Japanese production line equipment, in the following year to produce stereotyped polypropylene rope, the product won the national silver.

Third, knitting

70 years, warp knitting, weft knitting technology, has been widely used in weaving. In 1973, a successful trial with tight knit nylon wide. In 1982, Italy introduced crochet machine, advanced technology, the production of wide varieties, especially adapted to thin fabric with decorative category, such as lace, elastic tape, screens, decorative bands. The basic process for: dyeing - Winding - Weaving - ironing - packaging.

70's before the fire hose tube with flat loom weaving, tube diameter size of the deformation, and low output. The second half of 1974, trade associations, the development of the Sub-woven tube, in accordance with the principles of knitted, woven using latitude and longitude, and relying on into a circle into a circle in yarn, the use of yarn into a circle arc of the cylinder with the settlement, will not warp interwoven with weft to form a whole, and become tubular liner by the weft insertion knitted fabric, the product outlet pipe coating and high-pressure fire hose production process technology ranks the highest level.
