Abstract

The invention relates to a method for modifying Kevlar fiber by treating a nano sol through plasma, which comprises the following steps: (1) preparing inorganic nano particles into sol solution by ultrasonic oscillation technology; or (2) carrying out a hybridization reaction of precursor solution of organic-inorganic nano particles and the inorganic nano particles to prepare sol solution; (3) coating the sol solution on the surface of the Kevlar fiber; (4) drying the Kevlar fiber at a temperature of between 10 and 150 DEG C, collecting solvent, then introducing the Kevlar fiber in a plasma atmosphere area through a plasma generating device for surface modification treatment by the plasma; and finally, carrying out on-line winding of the treated Kevlar fiber in an automatic winding machine and adjusting the wiring speed of the Kevlar fiber by adjusting the speed range of a winding shaft. The combined performance between the Kevlar fiber treated by the method and the organic base materials is improved greatly; and the method has simple process, good treatment effect, low cost, difficult environmental pollution and reduction of the energy consumption.

Description

technical field [0001] The invention belongs to the field of preparation of Kevlar fiber surface modification, in particular to a method for plasma treatment of nano sol Kevlar fiber modification. Background technique [0002] Kevlar fiber is currently one of the most comprehensive and high-performance organic fibers produced on a large scale in the world.
