Guess the pros and cons. It is difficult to identify the front and back sides of some cases and bags because of their special texture. The following is how the luggage and webbing factory teaches you to identify the front and back of the webbing. In fact, we can identify it according to the pattern of the webbing, the front of the pattern is clear and clean, the pattern lines are obvious, the layers are clear, and the color is bright. Generally, the patterns on the front are clearer and more beautiful than those on the back. The front pattern of plant and color matching patterned fabrics with striped appearance must be clear and pleasing. This pattern is especially obvious when weaving jacquard belts.
Backpack webbing manufactor The progress of process technology has brought about the upgrading of edging webbing products. In 1979, the trial production of the domestic generation SD9-9 rubber ingot belt was successful, which ended the history of rubber ingot belt products relying on imports. 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. Fuzhou customized Backpack webbing 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.
At present, more than 90% of the market is made of cotton polyester thread or polyester cotton thread, but there are few pure cotton threads in the market, and the price is surprisingly high! Polyester cotton yarn just neutralizes the advantages of pure cotton and polyester, depending on the composition of polyester in cotton. Generally, the yarn of cotton ribbon is made by adding a small amount of polyester into cotton, so that it can have the advantages of pure cotton and polyester cotton.

If there is any hard block, it is polyester cotton yarn containing polyester, and if it is completely reduced to ashes, it is authentic pure cotton.
The unused ones from the knitting production line are called. The strength, width, thickness, elongation and stiffness described above are all measured on the knitting production line. The data measured on the knitting production line are called data. The safety belt installed in the car should be worn by the passengers after they get on the car. The use process is an aging process, and its strength will decline. In order to ensure that the safety belt can effectively protect the passengers before the vehicle is scrapped, the strength of the webbing shall be measured after simulating the working conditions. This strength is called the strength after the environmental test. After the environmental test, the strength includes light treatment, low temperature treatment, high temperature treatment, immersion test and wear treatment.
