Description
Technical Field
The invention belongs to the field of preparation of composite antibacterial fibers, and particularly relates to a method for preparing a PA 6/mesoporous nanomaterial @ Ag composite antibacterial fiber based on an in-situ polymerization method.
Background
In the current society, environmental pollution is serious, the ecological environment is gradually worsened, and the development and utilization of functional protective textiles by people are accelerated by special living microenvironments such as various closed spaces and the like. At present, common textile fibers do not have antibacterial capacity, and can provide living and breeding environments for bacteria under certain conditions, thus threatening human health. The main method for solving the problem of fiber antibiosis is to introduce antibacterial agents (comprising organic antibacterial agents, organic metal antibacterial agents, compound type antibacterial agents, nano metal antibacterial agents, inorganic powder metal-loaded antibacterial agents and the like), and compound modification is carried out by utilizing nano particles with antibacterial action and a polymer matrix to prepare the modified fiber with antibacterial action. Nowadays, the antibacterial fiber is widely applied and has a large demand, but the problems of large addition amount of functional components, difficult dispersion, unstable high-temperature processing, low continuous production yield and the like cannot be effectively solved by the prior art, and the color problem of the copper antibacterial agent cannot be solved, so that the antibacterial fiber cannot be efficiently produced in a large scale and cannot meet the wide demand of the market.
At present, the main method for realizing the antibacterial function of the fiber is through a surface modification technology, a blending modification technology and an in-situ introduction technology. The surface modification technology is to attach the antibacterial component to the surface of the fiber or fabric by the chemical bond formed between the antibacterial component and the surface of the fiber or fabric, thereby achieving the antibacterial effect. Patent CN101942759A is an antibacterial fiber or fabric with silver attached on the surface, which is obtained by adding fiber into solution containing silver nitrate to adsorb silver nitrate in the solution, and then reducing the adsorbed fiber. The method cannot form a uniform and stable antibacterial coating, and has a limited antibacterial time, so that the method cannot achieve durable antibacterial. Meanwhile, the whole process is complex and is very easy to pollute the environment. The blending modification technology is to add the antibacterial component into the polymer directly or after modification, prepare the antibacterial master batch through screw extrusion, and prepare the antibacterial fiber through the melt spinning technology. Patent CN 105332082B is to disperse zirconium phosphate powder, multi-sulfhydryl compound and silver nitrate in organic solvent, then remove the solvent, obtain silver-carrying zirconium phosphate antibacterial powder at high temperature, and then melt-spin with polyamide. The method not only needs to add a multi-sulfhydryl compound for reduction and modification, but also needs to introduce an organic solvent, and has the disadvantages of complex process method, low efficiency and environmental pollution. The in-situ introduction technology is to prepare the composite resin with antibacterial property by introducing antibacterial components in situ in the resin polymerization process and then prepare the antibacterial fiber by a melt spinning method. The patent CN105524260B introduces the copper oxide/cuprous oxide antibacterial components into the polymerization process of the polyester in situ, has the characteristics of large addition amount, uniform dispersion, lasting antibacterial performance, simple operation and the like, and is a key technology for realizing continuous large-scale production.
