preparation example Construction

[0029] A preparation method for bamboo fiber, characterized in that it is prepared in this way:

[0030] Step 1 Sample preparation: Since the dense structure of bamboo is not conducive to the penetration of chemical liquid, when preparing the sample, the bamboo is planed or split into bamboo chips with a thickness of 0.1 ~ 1mm to facilitate softening treatment. Uniform penetration of liquid medicine in the process, rapid action;

[0031] Step 2 softening: Although bamboo has neatly arranged biological cells, high strength and good elasticity, its workability is worse than that of hemp and other bast plants. Therefore, bamboo chips are treated with lye to make bamboo The tablet is softened, and can dissolve and remove a certain amount of gum impurities, destroy the chemical bond between cellulose and gum, and separate the cellulose from most of the gum. Softening the bamboo slices can greatly reduce the pressure of subsequent preparations. The specific method is: use 5-30 g / L...

Embodiment

[0047] Plane the bamboo into 0.1mm thick bamboo chips with a shaving machine; use 20 g / liter of NaOH solution, add 2% sodium sulfite, sodium polyphosphate, and penetrant JFC, at a temperature of 100 ° C, a bath ratio of 1: Under the condition of 20, the bamboo slices were treated for 1.5 hours; the bamboo slices were washed repeatedly with hot water to remove the chemicals on the bamboo slices; the softened bamboo slices were rolled with the groove roller of the softener, and the pressure was 2500Pa Force most of the colloid to be stripped off from the bamboo chips to obtain bamboo fibers that contain less colloidal impurities and are softer and easier to handle; repeatedly rinse the bamboo fibers with hot water to separate the colloidal impurities on the fibers from the bamboo fibers; / L H 2 o 2 solution, add 20% urea, and add 2% sodium silicate, sodium sulfite, sodium polyphosphate, penetrant JFC, at a temperature of 80°C, a pH value of 6.5, and a bath ratio of 1:20. Bambo...

Abstract

A process for preparing bamboo fibres from bamboo includes preparing raw material, softening, water washing, rolling, water washing, treating by urea and oxygen, water washing, boiling in alkali solution, water washing, bleaching by urea and oxygen, acid washing, dewatering, loosening and drying in air. The said bamboo fibres can be used to weave cold fabrics.

Description

Technical field: [0001] The invention belongs to the field of textiles, and relates to a method for preparing bamboo fibers. Background technique: [0002] As a material for entertainment, writing, clothing, construction, life, and art, bamboo has penetrated into every living space of people, and is now more widely used in papermaking. And the most impressive thing about it is its coolness. With the improvement of people's living standards, the development of cool green fiber has won the hearts of the people. [0003] The patent number is 00135021.8, and the patent name of the invention is the process of producing viscose fiber pulp by using bamboo. fiber production. But this processing method has destroyed the character of bamboo fiber fundamentally, therefore, its essence just develops a kind of new production raw material of viscose fiber, and the fiber of production can not become the bamboo fiber in true sense. [0004] About the development of other forms of bamboo...
