Such as patent application numbers: 02151265.5, 02133494.3, 200310108826.1 and 200410060809.X, all describe a kind of manufacturing method of bamboo fiber for textile, adopt acid or alkali or other chemicals to process bamboo, but can produce a large amount of difficult-to-treat sewage, Causes environmental pollution; patent application number: 01123617.5 is only protection of treatment process and rolling equipment; patent application number: 02111380.7 protection content is only treatment process, which mentions softening treatment with softener, as for the composition of softener and softening process Conditions are not involved; patent application numbers: 200410046802.2 and 200410046835.7 are to take straw mold to carry out biological treatment of bamboo, microbial mold to bamboo treatment is actually to use the enzyme produced by mold to decompose non-cellulose in bamboo, and mold synthetase is affected The dual control of genes and substrates, different substrate concentrations, types of nitrogen sources, culture time, changes in pH value, trace elements, surfactants, etc. are all factors that affect enzyme production. The requirements are strict, so the biggest disadvantage of this processing method to produce bamboo fiber is the long cycle and unstable quality

Embodiment 1

[0014] A kind of bio-enzyme method produces the raw bamboo fiber for weaving, and its production process is:

[0015] 1. Cut off the moso bamboo and cut it into bamboo slices, boil it in boiling water for 1 hour, take it out, crush it, and hammer it into filaments. Then put it in a pressure cooker and cook at 120°C for 4 hours to remove part of pectin, hemicellulose and lignin;

[0016] 2. The above-mentioned pretreated bamboo shreds were immersed in a solution of 1.0 mg / ml pectinase, 1.0 mg / ml hemicellulase, and 2.0 mg / ml ligninase at 40 ° C for 7 days;

[0017] 3. Take out the bamboo cellulose fibers decomposed by enzymes, wash them, bleach them, oil them, soften them, and loosen them to obtain bamboo fibers with an average fineness of 1050 metric pieces.

Embodiment 2

[0019] A kind of bio-enzyme method produces the raw bamboo fiber for weaving, and its production process is:

[0020] 1. Cut off the green bamboo skin and cut it into bamboo slices, put it in boiling water and boil for 2 hours, take it out, crush it, and hammer it into filaments. Then put it in a pressure cooker and cook at 100°C for 6 hours to remove part of pectin, hemicellulose and lignin;

[0021] 2. Immerse the above-mentioned pretreated bamboo shreds in a solution of 20 mg / ml pectinase, 15 mg / ml hemicellulase, 20 mg / ml ligninase and 5 mg / ml cellulase at 30 °C 3 days for processing;

[0022] 3. Take out the bamboo cellulose fibers decomposed by enzymes, wash them, bleach them, oil them, soften them, and loosen them to obtain raw bamboo fibers with an average fineness of 2,700 metric pieces.

Embodiment 3

[0024] A kind of bio-enzyme method produces the raw bamboo fiber for weaving, and its production process is:

[0025] 1. Cut off the moso bamboo and cut it into small pieces, boil it in boiling water for 1.5 hours, take it out, crush it, and hammer it into filaments. Then put it in a pressure cooker and cook at 110°C for 3 hours to remove part of the pectin, hemicellulose and lignin;

[0026] 2. The above-mentioned pretreated bamboo shreds were immersed in a solution of 50 mg / ml pectinase, 40 mg / ml hemicellulase and 50 mg / ml ligninase at 60 ° C for 4 days;

[0027] 3. Take out the bamboo cellulose fibers decomposed by enzymes, wash them, bleach them, oil them, soften them, and loosen them to obtain raw bamboo fibers with an average fineness of 2650 metric pieces.

Abstract

The invention discloses a method to make bamboo origin fiber that the process includes following steps: cutting the bamboo and dissecting into sheet, adding to boiling water, taking out and crushing, hammering to filament, adding into pressure cooker to boil, dipping the processed bamboo filament into solution that contains biology enzyme to gain fibrin fiber, cleaning, whitening, oil pumping, softening, shredding the fibrin fiber, the bamboo origin fiber would be gained.

Description

technical field [0001] The invention relates to a manufacturing process of natural bamboo fibers for textiles, in particular to a process for preparing raw bamboo fibers for textiles from bamboo, and belongs to the field of textiles. Background technique [0002] Bamboo is a perennial plant with short growth period, high yield and easy cultivation. Bamboo resources in my country are very rich, including symaxial clustered bamboo species suitable for tropical growth, uniaxial scattered bamboo species grown in subtropical regions, and compound axial mixed bamboo species grown in high latitudes with strong cold resistance. According to statistics, there are 48 genera and more than 500 species of bamboo plants in China. These bamboo species are distributed on the vast land south of 40° north latitude. my country's existing bamboo forest covers an area of ​​4.21 million hectares, with a reserve of 127 million tons. Bamboo species, reserves, and output all rank first in the wor...
