The longitude and latitude are interwoven. [Subject] After twisting, the yarn is warped into a bobbin (pan head), and the weft yarn is shaken into a bobbin, which is woven on the loom. In the 1930s, it was used for hand pulled wood looms and iron wood looms. In the early 1960s, the 1511 loom was converted into a belt loom, which is still widely used. Due to the small width of the belt, the weaving methods are different, ranging from single, double, dozens of pieces, from single layer to double layer. In 1967, the research group of shuttleless weaving belt with workers as the main body in the industry successfully designed and manufactured a high-speed single shuttleless loom by itself, which realized that the weaving belt does not need shuttles, and the process is shortened, the floor area is small, and the labor productivity is improved, which is an innovation in the history of Chinese weaving belt technology.
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.
Hygiene: Harbin Selvedge webbing manufactor It is a natural fiber, and its main component is cellulose, with a small amount of waxy substances, nitrogenous substances and pectin. After various inspections and practices, the pure cotton ribbon has no stimulation or negative effect when contacting with the skin. It is beneficial to the human body and has good sanitary performance after being worn for a long time. Heat resistance: Harbin Customized Selvedge webbing The heat resistance is good. When the temperature is below 110 ℃, it will only cause water evaporation on the webbing and will not damage the fiber. Therefore, the use, washing, printing and dyeing of pure cotton webbing at room temperature have no impact on the webbing, which improves the washing and wear resistance of pure cotton edging webbing.
Here are some examples of the production process of radio lanyard, toy lanyard, flashlight lanyard and camera lanyard. 1. Wholesale of webbing: nylon, pp, polyester and high elastic cotton are generally used to make lanyards, and the general specifications are 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 16mm, 20mm and 25mm wide. 2. Accessories: general accessories include metal clasps, certificate clips, etc., and plastic ones include aircraft clasps, plug buckles, safety buckles, etc. 3. Assembly: first print, cut according to the specified size, add string, plastic buckle, glue or press metal sheet, and then package. After inspection, a lanyard can be shipped in this way.
