Abstract
The invention provides a method for degumming flax bast fiber microbe in solid state. The method comprises the following steps: adding pre-culture special bacterium into flax bast fiber by a solid state method to complete degumming under a condition of smaller water addition ratio; carrying out solid-state degumming on the flax bast fiber by using microbe at a temperature of between 30 and 35 DEG C; and adjusting pH value of the degummed flax bast fiber to between 5 and 8. The mass ratio of the flax bast fiber to water is 1:1-5. The dosage proportion of microbial fluid is between 2 and 6 percent. The method is particularly suitable for the requirement of flax semi-degum prepared process fiber, is easy to operate, and can directly judge the degumming effect. The method fundamentally solves the problems of pollution generated by the chemical degumming method; wastewater generated by degumming does not contain any chemical medicinal residue, and does not pollute the environment; and the degummed textile fiber raw material can completely achieve the requirement of textile, and the rate of long fiber growth is increased by 8 percent compared with the prior art. The method reduces environmental pollution while improving resource utilization ratio, and has wide application prospect.
Description
Technical field
The present invention relates to a kind of method for degumming and pulping of flax bast fiber, particularly select for use microorganism-bacillus subtilis (Bacillus subtilis, down together) to carry out the method for flax bast fiber solid degumming.
Background technology
Flax bast fiber in the past all adopt warm water, warm water add bacterium and traditional rain and dew Process of retting flax with come unstuck just can obtain weaving required fibrous raw material, particularly warm water, that warm water adds bacterium method water consumption is big, general water addition ratio is between 1: 20 ~ 30.Long numb yield is very low.Can produce a large amount of waste water in the process of coming unstuck, be difficult to administer, environmental pollution is serious.
The water addition ratio of raw material can produce a large amount of waste water in the process of coming unstuck equally when the liquid microbial method of nearly more than ten years development was come unstuck about 1: 20 ~ 30, decreased though sewage system is managed cost, but still was one of difficult problem of puzzlement industry development.
For this reason, demand developing a kind of novel water-saving urgently, production technology efficient, environmental protection substitutes and has technology now.
Summary of the invention
The method that the purpose of this invention is to provide the degumming flax bast fiber microbe in solid state of a kind of novel water-saving, efficient, environmental protection.
The method of a kind of degumming flax bast fiber microbe in solid state of the present invention mainly may further comprise the steps:
1) flax bast is partly made fibre bundle;
2) be that 1: 1～5 ratio adds entry according to the mass ratio of flax bast fiber and water; Described broussonetia papyrifera phloem fiber pH value of aqueous solution is adjusted to 5～8;
3) insert microbial inoculum; Insert the pre-incubated microbial inoculum of Total Water 2～6% (V/V), 20～35 ℃ came unstuck 2～4 days.
As long as under the above-mentioned condition of coming unstuck, can guarantee the microorganism used therefor normal growth.
Described microorganism is preferably bacillus subtilis (Bacillus subtilis).The cultural method of the bacterium liquid of described bacillus subtilis (Bacillus subtilis) is: the urea of glucose 3%, 0.2%, 0.65% sodium hydrogen phosphate, 0.4% potassium dihydrogen phosphate, 0.1% sodium chloride, 0.12% magnesium sulfate.Surplus is a water.The nature pH value, 0.1MPa/CM
2Sterilized 20 minutes, it is standby that cooling inserts 30 ℃ of static cultivations of former bacterium 24 hours, and the described percentage of this section is (W/V).
Described usually time is preferably 2 days.
Another characteristics of method of the present invention are because water is few, and the more original inventory in the pond of coming unstuck of equal volume has increased 3-4 doubly.The waste residue that the process of coming unstuck produces can be gone back the field on the spot, has alleviated the solid content load in the waste water.Solved rain and dew retted fibres, warm water and warm water and added that the water addition ratio of bacterium retted fibre is big, the problems such as severe contamination of chemical method.
Tu Chu advantage is to control the degumming degree of bast fiber especially, prepares process of fiber or filament and produces needs to satisfy.
This method is specially adapted to the requirement of flax half deguming preparation technology fiber, and process is easy to operate can judge degumming effect very intuitively.In this comes unstuck process, desirablely go out fibre bundle and observe, treat its peelable reticulating, showing promptly that flax bast fiber has been finished comes unstuck.The waste water that produces in the process of will coming unstuck is removed, with promptly obtaining weaving technology fibrous raw material after clear water washing and the drying.
The method for degumming and pulping of flax bast fiber provided by the invention has fundamentally been eliminated the pollution problem of being come unstuck and being produced by traditional method, and no any chemical medicinal residue in the waste water that produces that comes unstuck does not have any pollution to environment, is environmental type technology; The back gained fibrous raw material that comes unstuck reaches the requirement of slurrying weaving fully, and the existing technology of long flax rate has improved 8%.This method has realized having reduced environmental pollution when improving resource utilization, has broad application prospects.
