Problems solved by technology

[0005] However, bamboo raw materials must be degummed and refined before they can become bamboo fibers. After complete degumming, the fiber fineness is 0.05tex, and its length is less than 5mm. Processing on Spindle Spinning Machine
Mechanical rolling can ensure the uniformity of bamboo fiber, but the result of mechanical drafting is unstable

Embodiment

[0032] Table 1 Specific parameters of bamboo fiber prepared from different bamboos

[0033]

[0034] The length of the bamboo slices of different bamboos in Table 1 is 20-40cm, the width is 5-10cm, the pressure of cooking the bamboo slices is 1-2MPa, wherein the bamboo slices are crushed into bamboo shreds with a roller 40 times the weight of the bamboo slices, and steamed The overheating pressure of bamboo shreds is 3~4MPa, and the heating gas volume for cooking bamboo shreds is 2.5 m 3 / kg·h, the cooking time of shredded bamboo is 1~2h.

[0035] Finally, the crude bamboo fiber degummed by raw biological enzymes is further washed, bleached and softened to obtain the bamboo fiber required for textiles. The content of impurities such as hemicellulose, lignin and pectin in the bamboo fiber is less than 1%.

Abstract

The invention provides a method for rapid extraction of bamboo fiber from bamboo, and the bamboo fiber fully meets textile requirements. The preparation method for bamboo fiber belongs to the textile field. The preparation method for bamboo fiber comprises the steps of: bamboo sheet preparation, bamboo sheet cooking, crushing decomposition, bamboo filament cooking, bio-enzyme degumming, and after-treatment. The preparation method for bamboo fiber provided by the invention has the advantages of simplicity, short process, no pollution, environmental protection, low energy consumption, and obvious economic benefits.

Description

technical field [0001] The invention relates to a method for making plant fibers into spinnable fibers, in particular to a method for preparing bamboo raw fibers, which belongs to the field of textiles. Background technique [0002] Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance and good dyeability, and at the same time has natural antibacterial, antibacterial, mite removal, deodorant and anti-ultraviolet functions. The development and utilization of bamboo fiber has become a research topic. [0003] The chemical components of bamboo fiber are mainly cellulose, hemicellulose and lignin, all of which are high polysaccharides, and the total amount accounts for more than 90% of the dry weight of the fiber, followed by protein, fat, pectin, tannin, pigment, As...
