Embodiment 1

[0022] (1) Mix the bamboo powder and the dispersion solution with a temperature of -12℃ according to the weight ratio of 1:11. The dispersion solution is made by mixing sodium hydroxide, urea and distilled water according to the weight ratio of 9:13:78. After ultrasonic vibration for 8 minutes Remove the dispersion solution by suction filtration, rinse the obtained filter cake with deionized water, soak it with 10wt% sulfuric acid solution for 10 minutes, remove the sulfuric acid solution by suction filtration, wash the filter cake with distilled water, and bake at 80°C for 3 hours to obtain bamboo fiber;

[0023] (2) Put the bamboo fiber treated in step (1) into the flask, add deionized water, the amount of deionized water is 30 times the weight of the bamboo fiber, and then add ammonium persulfate, the amount of ammonium persulfate is the amount of bamboo fiber After reacting at 80℃ for 15 minutes, take out the bamboo fiber and rinse with deionized water for use;

Abstract

The invention provides a modification method of bamboo fibers, which includes steps of: (1) uniformly mixing bamboo fiber and a dispersion solution, performing ultrasonic vibration and suction filtration to obtain filter cake, washing the filter cake with deionized water completely, soaking the filter cake in sulfuric acid solution, then performing suction filtration to remove the sulfuric acid solution, washing the filter cake in distilled water, and drying the filter cake to obtain bamboo fibers; (2) adding the bamboo fibers to a flask, adding deionized water and ammonium persulfate, after areaction, moving out the bamboo fibers and washing the bamboo fibers with deionized water completely for later use; (3) adding the bamboo fibers, treated in the step (2), into a reactor, adding deionized water, a modifier and a catalyst with uniform mixing, feeding nitrogen, sealing the reactor and irradiating the reactor under Co[60]-gamma ray; (4) washing and drying the irradiated bamboo fibersin the step (3) to obtain the bamboo fibers. The method can improve the affinity of the bamboo fibers to coatings and improve uptake quantity and various fastnesses of a coating dyeing process.

Description

Technical field [0001] The invention relates to the technical field of textiles, in particular to a method for modifying bamboo fibers. Background technique [0002] Bamboo is widely distributed in our country and occupies an important position in our country's economy, culture, and life. The bamboo fiber extracted from bamboo has attracted more and more attention. As a kind of natural fiber, bamboo fiber is degradable and will not burden the environment. Bamboo fiber has good moisture absorption, air permeability, antibacterial and anti-ultraviolet properties. The fabric made of bamboo fiber is comfortable and beautiful. Favored by people. Bamboo fiber is recognized as the "most potential" fiber material, so further development and modification of bamboo fiber are of great value. The bamboo fiber is grafted and modified. Under certain conditions, it can be copolymerized with an appropriate grafting monomer to retain the inherent characteristics of the bamboo fiber, and the ph...
