Abstract
The invention discloses a method for preparing mulberry bast fibers, belonging to the technical field of textile industry. The method comprises the following steps: performing constant pressure steam explosion on the mulberry bast part, sterilizing, removing impurities, fermenting, sterilizing, stamping, performing other processes, thereby obtaining the mulberry bast fibers. The invention provides a method for preparing mulberry bast fibers, and the mulberry bast fibers prepared by the method are high in yield.
Description
Technical field
The invention belongs to technical field of textile industry, particularly relate to a kind of preparation method of mulberry bast fiber.
Background technology
Mulberry tree is a kind of fallen leaves wood or shrub, up to 15 meters.Mulberry tree originates in central China, and existing various places, north and south are extensively cultivated, and is many especially with various places, the middle and lower reach of Yangtze River.The leaf of mulberry tree can be used as the feed of silkworm, and timber can utensil processed, and branch can compile large bamboo or wicker basket, and mulberries can edible, wine brewing, and leaf, fruit and root micromicro are used as medicine.
Wherein, the bast part of mulberry tree is made up of the cellulose of about 30% and the colloid of about 70%, and in this colloid, pectin accounts for 26.37%, lignin 7.04%.In mulberry tree, these fibers of bast part are commonly referred to as bast fiber, after processing process, can be used as required fibrous raw material of weaving.But due to the pectin content in mulberry tree bast part higher, the processing of mulberry bast fiber is increased, and productive rate is low.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of preparation method of mulberry bast fiber, and the mulberry bast fiber productive rate that the method obtains is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A preparation method for mulberry bast fiber, the method comprises the following steps:
A, the bast part of mulberry tree is carried out constant pressure vapor explosion 5 minutes ~ 10 minutes under pressure is 1.5MPa ~ 2.0MPa;
B, the mulberry tree bast part obtained through step A process is made fibre bundle, then carry out sterilization, removal of impurities;
C, the mulberry bast fiber bundle obtained through step B process is put into the fermentation tank that bacillus subtilis bacteria culture fluid is housed, then regulate the pH value of the material in fermentation tank in the scope of 5 ~ 9, sealing, heat-preservation fermentation 2 days ~ 3 days at 30 DEG C ~ 40 DEG C; Wherein, the cultural method of described bacillus subtilis bacteria culture fluid is: by glucose, urea, sodium hydrogen phosphate, sodium dihydrogen phosphate, sodium chloride, magnesium sulfate and water glucose by ratio of weight and the number of copies: urea: sodium hydrogen phosphate: sodium dihydrogen phosphate: sodium chloride: magnesium sulfate: the ratio of water=30:2:7:4:1:1.5:1000 mixes, then sterilizing 15 minutes ~ 30 minutes at 120 DEG C ~ 121 DEG C, cooling access bacillus subtilis, at being placed in 28 DEG C ~ 32 DEG C, shaking table cultivates 48 hours, obtained;
D, the mulberry bast fiber Shu Jinhang sterilization by obtaining through step C process, washing, then put into the trypsin solution that concentration is 10g/L, be heated to 50 DEG C ~ 55 DEG C, soaks 30 minutes ~ 45 minutes;
E, the method for the mulberry bast fiber Shu Caiyong one side water obtained through D step process being rinsed beating are on one side carried out beating fine, then dry, obtain this mulberry bast fiber.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The mulberry bast fiber productive rate that the present invention obtains is high, and pectin residual volume is few.
