Siping Customized 3-strand twisted rope Comfortable. Silk is composed of protein fiber, which has good biocompatibility with human body. In addition, its surface is smooth, and its friction stimulation coefficient to human body is low among all kinds of fibers, only 7.4%. Therefore, it follows the curve of the human body with its supple texture. 2、 Good moisture absorption and desorption. Silk protein fiber is rich in many hydrophilic groups such as amino group (- CHNH), amino group (- NH2), and because of its porosity, it is easy for water molecules to diffuse, so it can absorb or emit water in the air, and maintain a certain amount of water. At normal temperature, Customized 3-strand twisted rope Manufacturer It can help the skin to retain a certain amount of moisture, so as not to make the skin too dry; Wearing it in summer can quickly dissipate sweat and heat from human body, making people feel cool.
Indirect plate making method: the indirect film is first exposed, hardened with 1.2% H2O2, developed with warm water, and dried to make a strippable graphic negative. During plate making, the adhesive film surface of the graphic negative is closely attached to the stretched screen, the adhesive film is tightly attached to the wet screen by extrusion, the film base is removed, and the screen is dried by wind. Process flow: 1. Stretched wire mesh - degreasing - drying. 2 Indirect film - exposure - hardening - development - fitting - drying - revision - blocking. 3 Straight mixed plate making method: first, paste the photosensitive adhesive layer on the screen frame with water, alcohol or photosensitive adhesive, dry it with hot air, remove the substrate of the photosensitive film, and then print the plate. After developing, the screen plate is made.
One of the complete knowledge of printing types. There are many kinds of bag ribbon printing. Today, it is divided into two parts for everyone to talk about. If you like it, you can have a detailed look. It should be helpful to you. Here is the first part. Bag webbing transfer printing. The pigment is printed on the paper by printing method to make transfer printing paper, and then the color is transferred to the fabric by high temperature (heating and pressing on the back of the paper). It is generally used for chemical fiber fabrics, characterized by bright colors, fine layers, lifelike patterns, and strong artistry. However, this process is currently only applicable to a few synthetic fibers such as polyester. Transfer printing process is simple, investment is small and production is flexible. It is popular in the market at present But to be honest, compared with other types of printing, the price of this transfer printing is a little high, but it has a certain level.
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.
