[0049] The first embodiment

[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: Cut the three-year-old bamboo, bamboo or green bamboo according to the specified length of the tip, middle, and head of the bamboo. The length of the middle part is cut to 5 meters, and the tip and head are 1 to 3 meters. .

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

[0053]Step 102: Soften: Then respectively send to the tip, middle, and head softening tanks to soak and soften. The softening fluid is made of water, sodium hydroxide, sodium carbonate, sodium sulfite, and sodium silicate in a mass ratio of 100:1:2:0.5:0.2 It is prepared in the proportion of, and the bamboo is completely immersed in the softening liquid, heated to 90 ℃ when softened, and kept warm for 150 minutes.

[0054] Step 103: Cleaning: Put the softened bamboo material in a designat...

[0061] Second embodiment

[0062] See figure 2 Shown is a schematic diagram of the process flow of the second embodiment of the present invention.

[0063] Step 200: Sawing: Cut annual bamboo, bamboo or green bamboo according to the specified length of the bamboo tip, middle, and head. The middle length is 8 meters, and the tip and head are 1 to 2 meters.

[0064] Step 201: Cut apart: Then cut the tip, middle and head of the bamboo into two half cylinders.

[0065] Step 202: fiber opening, classification, screening: send the bamboo to the bamboo fiber opening separator for processing, after combing, fiber opening, and airflow classification, the bamboo powder is removed by a vibrating screen to obtain the classified bamboo silk状fibre.

[0066] Step 203: Scouring: Put the bamboo filament-like fiber into a cooking pot (pool) and heat it for 60 minutes. The temperature during cooking is 100°C and the bath ratio is 1:30. The cooking liquor contains water, sodium hydroxide, Sodium car...

[0074] The third embodiment

[0075] See image 3 Shown is a schematic diagram of the process flow of the third embodiment of the present invention.

[0076] Step 300: Softening: Put the bamboo scraps into the softening tank to soak and soften. The softening solution is prepared with water, sodium hydroxide, sodium carbonate, sodium sulfite, and sodium silicate in a mass ratio of 25:1:2:0.5:0.2, and make The bamboo is completely immersed in the softening liquid, using room temperature when softening, soaking and softening time for 10 days.

[0077] Step 301: Washing: Put the softened bamboo material in a designated washing tank to soak for 15 minutes, and then rinse it to the processing area to dry.

[0078] Step 302: Opening, classification, and screening: The dried bamboo is sent to a bamboo opening and separating machine for processing. After combing, opening, and airflow classification, the bamboo powder is removed by a vibrating screen to obtain a good classification. Bamboo s...

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,...
