Abstract

The invention provides a method for preparing copper oxide antibiosis fibers. The method comprises the following steps: 1, carrying out fusion mixing on copper oxide powder, a silicon-containing surfactant and polyester slices to prepare functional master batches, wherein the diameter of the copper oxide powder is smaller than 0.8[mu]m, and the functional master batches comprise, by mass, 30-40% of the copper oxide powder and 4-6% of the silicon-containing surfactant; and 2, mixing the functional master batches with the polyester slices, adding the obtained mixture to a screw extruder, and spinning to obtain the copper-containing antibiosis fibers. An organosilicon quaternary ammonium salt and a cationic silicon-containing surfactant are used in fabrics in the invention, so the fabrics have good softness, resilience and smoothness, and an obvious antistatic effect, and the fibers obtained by commonly using the organosilicon quaternary ammonium salt and copper oxide have better spinnability and antibiosis than fibers obtained by individually using copper oxide.

Description

technical field [0001] The invention relates to the field of fiber textiles, and specifically discloses a method for preparing copper oxide antibacterial fibers. Background technique [0002] Antibacterial textiles are mainly divided into two categories: one is antibacterial textiles processed after finishing, which are widely used due to their simple process, large selection of antibacterial agents, and wide applicability. However, this kind of antibacterial textiles also shows many problems in the application, such as the persistence of antibacterial effect and the safety of leachate to human body. The other is antibacterial textiles made of antibacterial fibers. Compared with antibacterial textiles after finishing, antibacterial fibers show greater advantages. Copper can inhibit the growth of bacteria, viruses and fungi, and promote the metabolism of human skin. Copper-based antibacterial While fiber has good antibacterial properties, it also has good health care functio...
