1. What is fiber antibacterial masterbatch?
Antibacterial masterbatch is a functional masterbatch with antibacterial properties. It is generally added to plastics to provide antibacterial capabilities for plastic products. , Fiber antibacterial masterbatch is also a type of antibacterial masterbatch, but it is not added to the plastic, but to the fiber.
Fiber antibacterial masterbatch is a mixture of fiber antibacterial agent and plastic, melting and pelletizing. The production process is the same as the production of plastic antibacterial masterbatch, but there are differences in material selection. It is mainly used for antibacterial Melt spinning of fibers, such as antibacterial polyester, antibacterial polypropylene, antibacterial nylon and other antibacterial fibers can be produced by adding fiber antibacterial masterbatch, and then use antibacterial fibers to make antibacterial underwear, antibacterial socks, antibacterial jackets, antibacterial tablecloths, antibacterial Curtains etc.
2. What are the characteristics of fiber antibacterial masterbatch?
Various antibacterial agents are evenly dispersed in the matrix resin to form a concentrate, that is, antibacterial masterbatch. Fiber antibacterial masterbatch can The antibacterial fiber used to make it is specially used for fiber spinning, so it requires good spinnability and cannot affect the physical and chemical properties of the fiber. The main characteristics of fiber antibacterial masterbatch are:
1. Common fiber raw materials are PP, PET, PA, etc. Their processing temperatures are relatively high, so the first feature of fiber antibacterial masterbatch is to choose Most of the antibacterial agents are inorganic antibacterial agents that can withstand high temperatures, such as zirconium phosphate-loaded silver antibacterial agents.
2. The particle size of the antibacterial agent selected for the fiber antibacterial masterbatch should be very small, usually within 1 μm, because the holes of the spinning plate are very fine. If the particle size of the antibacterial agent is large, it will block the spinning. Silk holes will cause broken threads and the spinnability will be very poor.
3. The antibacterial effect of fiber antibacterial masterbatch is long-lasting and washable. Because most of the downstream applications of antibacterial fiber are clothing products, which must be washed frequently, the washability must be strong and the antibacterial effect must be long-lasting.
