Guangdong Customized Cotton ribbon The narrow Shenzhen ribbon or tubular fabric is made from various yarns. There are many kinds of belt fabrics, which are widely used in clothing, shoes, bags, industry, agriculture, military supplies, transportation and other industrial sectors. In the 1930s, Guangdong Customized Cotton ribbon manufactor All are handmade workshops with exquisite pictures of webbing, and the raw materials are cotton thread and hemp thread. After the founding of the People's Republic of China, the raw materials for ribbon gradually developed to nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major types of technology: weaving, knitting, knitting. The fabric structure includes plain weave, twill, satin, jacquard, double-layer, multi-layer, tubular and combined weave.
Direct dyes, suitable for cellulosic fabrics, have poor washing fastness and different light fastness, but the modified direct dyes will improve their washing color. Disperse dyes are suitable for viscose, acrylic, nylon, polyester, etc. The fastness to washing is different, polyester is better, and viscose is worse. Azo fuel (Naftol dye) is suitable for cellulosic fabrics. It has beautiful color and is more suitable for beautiful color and luster. Sulfide dyes are suitable, with dim color, mainly dark blue, black and brown, good light resistance and water washing resistance, and poor chlorine bleaching resistance. Long term storage of fabrics will damage fibers.
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.
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.
The convex and concave convex fabrics are compact and delicate on the front, with strip or pattern convex patterns, and rough on the back, with long floating lines. Wool fabric: single side woolen fabric, with the pile side being the front side of the fabric. For double-sided fleece fabric, the front side shall be the smooth and tidy side. Observe the selvage of the fabric: if the selvage is smooth, the neat side is the front side of the fabric. For double-layer, multi-layer and multiple fabrics, if the warp and weft density of the front and the back is different, the front side has a larger density or the front side has better raw materials.
Causes of bleeding. Some customers will customize the printing, but the PP fabric manufacturers sometimes have color bleeding when printing the PP ribbon, so the manufacturers should pay attention to the reasons when printing. Only by understanding these reasons can we reduce the occurrence of various conditions in the future use. What are the reasons for color bleeding when printing? There is dirt on the surface of the machine during printing. Cleaning up during production can reduce these problems.
