After the weft tube is formed by the yarn warp cylinder and weft winding, it is inserted on the fixed gear seat of the knitting machine, and the weft tube rotates along the 8-shaped track to draw the yarns to cross weave with 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. Spindle weaving technology has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment. The basic process of weaving is: bleaching and dyeing - weft rolling - weaving - off machine shearing - packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality.
Flat screen printing. The printing mould is a polyester or nylon screen (pattern) fixed on a square frame with hollow patterns. The pattern on the pattern plate can pass through the color paste, and the mesh without pattern can be sealed with a polymer film. When printing, the pattern is pressed against the fabric, and the color paste is placed on the pattern. The scraper is used to repeatedly scrape and press the color paste to reach the fabric surface through the pattern. Flat screen printing has low production efficiency, but wide adaptability and flexible application, suitable for small batch and multi variety production. Water slurry printing of bag webbing.
Selvedge webbing Customized Single and double layer belt Manufacturer What are the characteristics: moisture retention: because the pure cotton edging ribbon is a poor conductor of heat and electricity, its heat conductivity coefficient is extremely low, and because the cotton ribbon itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between the webbing, and the air is also a bad conductor of heat and electricity, the pure cotton ribbon has good moisture retention Customized Single and double layer belt Manufacturer Pure cotton ribbon makes people feel warm. Hygiene: pure cotton edging webbing is a natural fiber, which is mainly composed of cellulose, a small amount of waxy substances, nitrogen and pectin.
The printing is in the passenger compartment to enhance the matching and coordination with the color in the cabin. The binding ribbon printing will be dyed into various colors. People always hope that the color dyed will not fade within the specified time. Therefore, the belt has a specific color fastness test. The wrapped webbing belt is exposed to light, and like other substances, it will fade. The wrapped webbing has this characteristic, which is called light color fastness. In this test, the webbing is placed under representative strong light and exposed to the specified time. Then compare the bag webbing with the standard color card to evaluate a fading grade.
