Abstract

The invention discloses a method for preparing a silver ion antibacterial fiber. The method comprises carrying out melting mixing on silver ion powder, a siliceous surfactant and polyester slices to obtain a functional master batch, wherein the silver ion powder has the particle diameter less than 0.5 microns and based on the total mass of the functional master batch, mass percentage content of the silver ion powder is in a range of 16-20% and mass percentage content of the siliceous surfactant is in a range of 4-6%, mixing the functional master batch and the polyester slices, putting the mixture into a screw extruder and carrying out spinning to obtain the silver ion antibacterial fiber. The silver ion antibacterial fiber has strong bacteriostasis functions, good sterilization functions, excellent washing resistance and bacteriostasis and sterilization effects after multiple washing processes.

Description

technical field [0001] The invention relates to the field of textile fibers, in particular to a method for preparing silver ion 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, which show greater advantages compared with post-finish antibacterial textiles, and have antibacterial properties Excellent, durable, high safety and comfortable to use. Antibacterial fiber uses physical or chemical methods to introduce substances capable of inhibiting bacterial growth into the surface and interior of the f...
