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.
Suifenhe River special Selvedge webbing As an industrial product, it also has its own standard service life, which determines the length of our actual use of webbing. Generally, there are two kinds of situations at the end of use. One is that the problem of quality or external damage occurs within the service life, so it can no longer be used. The other is that Suifenhe River Selvedge webbing manufactor The damage is natural. It is also inevitable. Today we will talk about the life span in detail. Selvedge webbing How long is the life span?
There are two primary methods for coloring, one is to apply it to a wide range of dyeing (conventional dyeing), and the first is to treat it in chemical dye solution. The other method is to use paint to make the paint into tiny insoluble colored particles to stick to the fabric (dyeing of fibrous material stock solution is not included).

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.
