Abstract
The invention discloses an easily-cleaned antibacterial negative ion mattress and a preparation method thereof, and relates to the technical field of textile materials. When the antibacterial negative ion mattress easy to clean is prepared, tri (4-aminophenyl) amine reacts with di-tert-butyl dicarbonate and then reacts with p-phenylene diisocyanate to prepare a supramolecular assembly ligand, negative ion polyester fibers react with ethylene diamine and then react with the supramolecular assembly ligand and tetrabutylammonium phosphate to prepare supramolecular assembly negative ion polyester fibers, 8-aminocaprylic acid reacts with monoiodomethane to prepare an antibacterial agent, the antibacterial agent, 11-dodecenoic acid and trimethylolpropane triglycidyl ether react and then react with methyldiallyl silane and pentamethyl disiloxane in sequence to prepare a modified antibacterial agent, and the supramolecular assembly negative ion polyester fibers react with the modified antibacterial agent and are woven and cut to prepare the antibacterial negative ion mattress easy to clean. The easy-to-clean antibacterial negative ion mattress prepared by the invention has excellent easy-to-clean performance, antibacterial performance and durable performance.
Description
Technical Field
The invention relates to the technical field of textile materials, in particular to an antibacterial anion mattress easy to clean and a preparation method thereof.
Background
The anion fiber is a fiber with the anion releasing function, and the anion released by the fiber has obvious effects on improving the air quality and the environment, and particularly the health care effect of the anion on human bodies is more and more accepted by people.
The negative ion fiber is produced through adding nanometer level tourmaline powder with negative ion releasing function into the fiber during the fiber producing process to make the tourmaline powder embedded into the fiber surface and to hit the oxygen molecules around the fiber with the electrons emitted from the tourmaline to form charged negative oxygen ions. The anion fiber on the market mainly comprises viscose anion fiber, terylene anion fiber, polypropylene anion fiber, acrylic anion fiber and the like. The textile woven by the anion fiber in the market has the anion generating effect which is easy to rapidly decline along with use and water washing, and how to make the textile with the anion generating effect durable is a technical problem which is worth solving.
Disclosure of Invention
The invention aims to provide an easily-cleaned antibacterial anion mattress and a preparation method thereof, and aims to solve the problems in the prior art.
In order to solve the technical problems, the invention provides the following technical scheme:
