What is the principle of silk screen yarn?Silk screen yarn consists of five elements: screen plate, scraper, ink, printing table and substrate. The basic principle of screen printing is to use the basic principle of screen printing plate that the part of image and text is ink permeable and the part of non image and text is ink impermeable.
The main raw materials for screen production in China are mulberry silk, nylon wire and metal wire. The main types of screen can be produced are silk screen, synthetic screen and metal screen.
Nylon is developed by carothers, an outstanding American scientist, and a research team under his leadership. Nylon is the first synthetic fiber in the world. Nylon is an expression of polyamide fiber.The appearance of nylon has changed the appearance of textiles. Its synthesis is a major breakthrough in the synthetic fiber industry and a very important milestone in polymer chemistry.
It is a chemical fiber woven net made of nylon, nylon, polyester, nylon and other chemical fibers through silk screen mechanical processing. Jinlun has the function of resisting high temperature and alkali, polyethylene has the function of resisting acid, nylon net is the general name of these chemical fiber woven nets.
Screen plays an important role in flour production. The screens used in flour mills are classified into stainless steel screens and polyurethane screens.
Fabric fiber screen, also known as screen silk (hereinafter referred to as screen cloth for short), has always been an important auxiliary material for flour mills. Although it accounts for a small proportion of the total investment in the flour mills, it plays a key role, because flour is finally screened out through it, and the milling process is also balanced through its classification and sieving. Selecting a good screen is actually one of the key technical indexes of flour mills. Therefore, it is considered by more and more flour milling workers as an important factor to ensure a balanced and stable flour quality. The author talks about the selection and use of flour based on years of actual use.
Generally speaking, due to the different photosensitive materials used in screen plate making, the production process is also different.However, no matter which process is adopted, the following steps are indispensable in the process of screen plate production: selection of screen and screen frame, drawing, washing, etc. Photosensitive materials, exposure, development, drying.
Nylon net is a kind of chemical fiber woven net, which is made of chemical fibers such as nylon, nylon, polyester, nanofiber and so on. Nylon net has the function of high temperature and alkali resistance, while polyethylene has the function of acid resistance. Nylon net is the general name of these chemical fiber woven nets. Nylon mesh includes: (nylon blend,) nylon mesh, polyethylene mesh and sunscreen.
