Abstract

The invention discloses a preparation method of an anti-static bacteriostatic polyester staple fiber, belonging to the technical field of polyester staple fibers. The preparation method comprises thesteps of carrying out high-temperature anaerobic sintering on bamboo chips, so as to obtain activated carbon; blending and compounding the activated carbon with polyester, so as to generate an artificial fiber; and blending and stretching a natural mulberry fiber with the artificial fiber during traction and wiredrawing, so as to obtain the anti-static bacteriostatic polyester staple fiber. The preparation method has the beneficial effects that the smooth execution of a subsequent processing process of textile is promoted; the adopted activated carbon is prepared by sintering the bamboo chipsunder high-temperature anaerobic conditions, bamboos are acidic, the prepared activated carbon is acidic, and the growth and propagation of bacteria under the acidic condition are inhibited, so that abacteriostatic effect is achieved; and relatively deep stripes are longitudinally distributed on the surface of the mulberry fiber, the surface comprises a middle cavity structure and more micro-holes, the activated carbon is inserted into the micro-holes of the mulberry fiber, the interfacial adhesive force between the mulberry fiber, and the polyester fiber is increased by virtue of the activated carbon, and a durable bacteriostatic effect is achieved, so that the bacteriostatic activity of the polyester staple fiber is enhanced, and the polyester staple fiber has wide application prospectsin the textile field.

Description

technical field [0001] The invention discloses a method for preparing antistatic and antibacterial polyester staple fibers, which belongs to the technical field of polyester staple fibers preparation. Background technique [0002] Polyester staple fiber is a fiber obtained by spinning polyester (that is, polyethylene terephthalate, PET for short, which is polymerized by PTA and MEG) and then cutting it into tow. [0003] PET is in the shape of rice grains or flakes, with various varieties and colors. Usually, the main component of beverage bottles we come into contact with is polyester. Slice it, and generally go through two main processes of pre-spinning and post-spinning to produce polyester staple fiber. Yes, according to different needs, it can be cut into polyester staple fibers of different specifications in post-spinning, generally 4D-22D, and can be divided into two-dimensional and three-dimensional according to its crimp. 75% is used for polyester for chemical fibe...
