Abstract

The invention discloses a preparation method of multifunctional polypropylene fiber, and belongs to the technical field of preparation of functional materials and functional fiber. The preparation method comprises the following steps: 1, enabling functional metal ions to enter alpha-ZrP through ion exchange to form functional alpha-ZrP, then modifying the functional alpha-ZrP through KH550, acidifying a carbon material to obtain an acidified carbon material, modifying the acidified carbon material through an epoxy modifier E51 to obtain a modified carbon material, and adding the KH550-modified functional alpha-ZrP into the modified carbon material to form a multifunctional nanocluster; and 2, blending and granulating the multifunctional nanocluster and a polypropylene matrix at 180 to 230 DEG C, then carrying out drying, and finally preparing the multifunctional polypropylene fiber by adopting a melt spinning method. The adding amount of an antibacterial object component in the multifunctional polypropylene fiber is small, and the antibacterial object component is uniformly dispersed; and the multifunctional polypropylene fiber has a persistent function, and the preparation method is easy and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional materials and functional fibers, and in particular relates to a preparation method of multifunctional polypropylene fibers. Background technique [0002] At present, there are more and more varieties of polyester fiber functionalization, and the realization methods are different according to different functions. For example, in order to realize the functionalization of polypropylene fiber, the common methods are surface modification technology and blending modification technology. However, with the development of society, it becomes more and more difficult for a single function to meet the multi-field and multi-functional requirements. [0003] Patent CN101942759A is to add fibers to a solution containing silver nitrate to absorb silver nitrate in the solution, and then reduce the fibers after absorbing silver carbonate to obtain antibacterial fibers or fabrics with silver attach...
