[0050] see figure 1 Shown is a schematic diagram of the process flow of the first embodiment of the present invention.

[0051] Step 100: sawing off: sawing bamboo materials such as three-year-old Moso bamboo, Ci bamboo or green bamboo according to the specified length of the tip, middle and head of the bamboo, wherein the length of the middle part is cut to 5 meters, and the length of the tip and head is 1 to 3 meters .

[0052] Step 101: Cut open: Cut the tip, middle and head of the bamboo into two half cylinders respectively.

[0053]Step 102: softening: then sent to the tip, middle, and head softening tanks for soaking and softening. The softening solution is water, sodium hydroxide, sodium carbonate, sodium sulfite, and sodium silicate in a mass ratio of 100:1:2:0.5:0.2 The ratio of bamboo is prepared, and the bamboo is completely submerged in the softening solution. When softening, it is heated to 90 ° C and kept for 150 minutes.

Abstract

The invention provides a method for producing a bamboo fiber, comprising the following steps of sawing off, splitting and softening the bamboo, sending the bamboo material to a bamboo splitting separator to realize combing, splitting separation and airflow classification, thus obtaining the bamboo filament fiber; cooking and drying the bamboo filament fiber, cleaning, dehydrating, oiling and drying the bamboo filament fiber subsequently; and carrying out the enzyme treatment, thus obtaining the coarse bamboo fiber; subsequently carrying out fine treatment, cleaning and dehydrating, bleaching, cleaning, dehydrating, oiling, drying and curing by emulsion, thus obtaining the fine bamboo fiber. The method has high production efficiency, low processing cost and can prepare the bamboo fiber with the diameter within 0.03-0.15mm and the length within 30-300mm.

Description

【Technical field】 [0001] The invention relates to a production method of bamboo fiber. 【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, anti-mite, deodorant and anti-ultraviolet functions. Experts pointed out that bamboo fiber is a real natural environment-friendly green fiber. [0003] But so far, the production of bamboo fiber basically adopts operations such as sectioning, splitting, degreening, deyellowing, steaming, pressing and rolling into bamboo strands, which cannot be separated from the process of first forming bamboo slices and then forming bamboo fiber bundles. The technology is relatively backward, the production efficiency is low,...
