Abstract

The invention provides carbon nanotube regenerated bamboo fibers. The carbon nanotube regenerated bamboo fibers comprise hydrophilicity modified carbon nanotubes and regenerated bamboo fibers and are prepared by a viscose spinning process. A production method for the carbon nanotube regenerated bamboo fibers comprises the specific steps: (1) air-drying bamboo chips, then, submerging the bamboo chips in water for prehydrolysis, then, carrying out secondary cooking, then, carrying out pulp pulping, carrying out pulp washing, carrying out bleaching, carrying out neutralizing, carrying out impurity removal, carrying out pulping, and carrying out drying, so as to obtain regenerated bamboo fiber pulp; (2) submerging carbon nanotubes into a strongly acid solution, carrying out ultrasonic treatment for 5-10 hours at the temperature of 35 DEG C, cooling the solution to room temperature, then, filtrating to obtain filtrated residue, washing and filtrating the filtrated residue until the filtrate is neutral, and drying the filtrated residue so as to obtain the modified carbon nanotubes; (3) dispersing the modified carbon nanotubes into deionized water, carrying out ultrasonic dispersion, adding the dispersion into the regenerated bamboo fiber pulp, adding an aqueous solution of N-methyl morpholine, uniformly stirring so as to obtain a spinning stock solution, and obtaining the carbon nanotube regenerated bamboo fibers by the viscose spinning process. The carbon nanotube regenerated bamboo fibers prepared by the production method have the advantage that the mechanical properties and electrical conductivity of the fibers can be improved on the basis of not changing the comfort of the regenerated bamboo fibers.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a carbon nanotube regenerated bamboo fiber and a production method thereof. Background technique: [0002] Regenerated cellulose fiber is prepared from natural cellulose extracted from wood, cotton, hemp, bagasse, etc. as raw material through spinning process. Therefore, the development and application of regenerated cellulose fibers have attracted people's attention when environmental resources have attracted much attention. [0003] Regenerated cellulose fiber is composed of cellulose macromolecules. Different raw materials and processing techniques form different regenerated cellulose fibers. Common regenerated cellulose fibers include ordinary viscose fiber, modal fiber, tencel fiber and bamboo fiber. Regenerated bamboo fiber is obtained by cutting bamboo slices and air drying, and refining the bamboo slices into pulp required for composite fiber produ...
