Abstract
The invention discloses an anti-aging fiber and a preparation method thereof, and relates to the field of fibers. When the anti-aging fiber is prepared, the pyrrole mixed solution and the alkene mixed solution are polymerized and then react with 3, 5-di-tert-butyl-4-hydroxybenzyl alcohol to prepare ultraviolet absorption polyacrylate emulsion, acrylic acid, propylene glycol and propenyl-1, 3-sultone are polymerized to prepare polyacrylic acid emulsion, and the polyacrylic acid emulsion and the ultraviolet absorption polyacrylate emulsion are subjected to coaxial electrostatic spinning to prepare the anti-aging fiber. The anti-aging fiber prepared by the invention has the capabilities of static electricity resistance, flame retardance, antibacterial property and moisture absorption.
Description
Technical Field
The invention relates to the field of fibers, in particular to an anti-aging fiber and a preparation method thereof.
Background
The fiber is a substance with small fineness, diameter of only a few micrometers and maximum to tens micrometers, and length of hundreds or thousands times larger than diameter, and has certain flexibility and strength, the textile fiber is a fiber for manufacturing textile, namely, yarn and textile are manufactured in textile production, the unit body with proper length, flexibility and strength is manufactured, the textile fiber is classified into natural fiber and chemical fiber according to sources, the natural fiber is also classified into plant fiber and animal fiber, and the chemical fiber is also classified into artificial fiber and synthetic fiber.
The chemical fiber is a fiber obtained by processing through a chemical method, chemical fiber can not be influenced by the time of day, new varieties of chemical fiber are continuously emerging along with the development of technology, fiber performance is continuously improved, new application fields of the fiber for clothing are continuously expanded, the traditional textile industry category is already flushed out in the industrial application fields, traditional materials and high-performance materials such as steel, hardware, wood building materials and the like are being replaced, the fiber is expanded to wider application markets and high-technology fields, and the anti-aging fiber with the anti-static, flame-retardant, antibacterial and moisture-absorbing capabilities is introduced.
Disclosure of Invention
The invention aims to provide an anti-aging fiber and a preparation method thereof, which are used for solving the problems in the prior art.
An anti-aging fiber is prepared by coaxially and electrostatically spinning polyacrylic emulsion and ultraviolet absorption polyacrylate emulsion.
The polyacrylic emulsion is prepared by polymerizing acrylic acid, propylene glycol and propenyl-1, 3-sultone.
The ultraviolet absorbing polyacrylate emulsion is prepared by polymerizing pyrrole mixed solution and alkene mixed solution and then reacting with 3, 5-di-tert-butyl-4-hydroxybenzyl alcohol.
