Embodiment 1

[0016] An anti-corrosion and anti-bacterial functional fiber is prepared by the following process: blending PET chips with anti-corrosion and anti-bacterial agents to obtain functional PET chips; melting, spinning and cooling the functional PET chips to obtain tubular hollow fibers; The hollow fiber is introduced into an immersion tank containing silver ammonia solution for immersion, and then dried to obtain the antiseptic and antibacterial functional fiber.

[0017] In the present embodiment, the configuration method of the silver-ammonia solution in the dipping tank is: add ammonia water dropwise to the silver nitrate solution of 8mmol / L, until the precipitate produced at first is just completely dissolved; the tubular hollow fiber in the dipping tank The impregnation time is 250s, and the tubular hollow fiber after impregnation is dried at 85° C. under the condition of air atmosphere.

Abstract

The invention belongs to the technical field of novel fiber preparation and particularly relates to an antiseptic and antibacterial functional fiber and a preparation process thereof. PET slices are blended with an antiseptic and antibacterial agent to prepare functionalized PET slices; the functionalized PET slices are molten, spun, cooled and molded to prepare tubular hollow fibers; the tubularhollow fibers are introduced into a dipping tank containing a silver-ammonia solution for dipping and then are dried to obtain the antiseptic and antibacterial functional fiber. Compared with the prior art, the antiseptic and antibacterial functional fiber has the advantages of simple preparation process, convenient operation and controllable production cost; and the prepared antiseptic and antibacterial functional fiber has strong antibacterial ability, good stability and good popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of novel fiber preparation, and in particular relates to an antiseptic and antibacterial functional fiber and a preparation process thereof. Background technique [0002] Anti-corrosion and anti-bacterial fibers can not only be widely used in clothing and home textiles, but also have potential application value in industry. Currently. Mainly used in home textiles, underwear, sweatshirts, etc., especially clothing for the elderly, pregnant women and infants. Clothes made of this fiber have good antibacterial properties and can resist the adhesion of bacteria on the clothes, thereby keeping people away from the infestation of germs. The antibacterial fiber's resistance and killing effect on bacteria is not a one-time temporary effect, but a long-term effect of several weeks to years. The reason why it has this long-term antibacterial property is that it adopts a built-in design, which allows the antibacteri...
