Description
Technical field
The present invention relates to a kind of textile fiber, relate in particular to a kind of composite flora and in the application of preparing in textile fiber.
Background technology
In recent years, day by day exhausted along with petrochemical industry resource, bast-fibre enjoys doting on of human consumer because having the good characteristic such as ecology, environmental protection, and its demand is at increase year after year, the annual speedup 8% of global natural fiber.The maximum feature of bast-fibre raw material is that fibre content is high, and elongated being conducive to of fiber interweaves, and intensity is good; Fiber cell is little, cell wall is thick, wall chamber ratio is large; Because bast-fibre lumen is thin, fiber trivial matter opaqueness is high.But its shortcoming is fiber is not easy wire-dividing broom purification, make the fabric air-permeability degree made low.
In prior art, from numb raw material, prepare fiber, how by chemical process, the waste liquor contamination sublimity that chemical process produces in producing, damage to land, polluted air, and also it is high to consume energy, and power consumption and water consumption are large.Do not meet national energy-saving and reduce discharging policy.Material can not reach Efficient Cycle recycling.Chemicals cannot separate from waste liquid, and organism and chemicals mix, and organism also cannot be reused, and causes a large amount of losses.
Therefore, be necessary to develop biological fibre technology processed, fundamentally solve an above-mentioned pollution difficult problem, energy-saving and emission-reduction, water-saving, reduces production costs and improves the rate of utilization of material.
Summary of the invention
The object of the invention is the above-mentioned defect of the chemical legal system fiber that overcomes prior art, a kind of new fiber biological bacteria of preparing is provided.Contriver, by long screening operation, has obtained the biological bacteria that can realize foregoing invention object that is suitable for preparing fiber.
Particularly, the invention provides a kind of composite flora, its comprise Pseudomonas fluorescens (Pseudomonas fluorescens) that the acinetobacter lwoffii that preserving number is CGMCC No.5973 (Acinetobacter lwoffii), preserving number are CGMCC No.5974, this Wickerhamomyces anomalus bacterium of Wickerhamomyces anomalus(that preserving number is CGMCC No.5975 in malt juice liquid medium 25 DEG C cultivate three days, cell is spherical, avette, sausage shape, size is (4.8-14.4) × (3.6-7.2) μ m, has precipitation to form.25 DEG C, wort agar inclined-plane cultivation one month, bacterium colony cheese shape, oyster white, surface smoothing, not reflective, edge root shape.Corn Meal Agar Dalmau is dull and stereotyped to be cultivated, and produces pseudohypha).
Described composite flora can be used in prepares textile fiber.
The present invention also provides a kind of method of preparing textile fiber, and it mainly comprises step:
1) configuration of bacterium liquid: above-mentioned composite flora is configured to the composite bacteria aqueous solution according to following mass ratio, is bacterium liquid:
Acinetobacter lwoffii: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1-2:1-2:2-3;
2) raw material processing: crudefiber crop raw material is cut into chunks, and raw material is put into fermentation vat swollen;
3) preparation of fiber, it comprises step:
Biological degradation: by the raw material soaking after discongesting in the bacterium liquid configuring;
Wet sterilization: by the raw material after above-mentioned biological degradation from bacterium liquid, pull out, draining, pass into water vapor sterilizing;
Obtaining of fiber: the raw material after sterilizing is carried out to one section of corase grind, become fibrous bundle; Above-mentioned one section of corase grind is carried out to two sections of fine grindings, make fibrous bundle disperse into single fiber; Fibrous bundle in screening, the slurries of filtration after one section of corase grind and two sections of fine grindings, defibrination makes it make single fiber again;
Dry, combing: the above-mentioned fiber making is soaked in warm water, and then oven dry, combing, for the preparation of textile fiber.
The density of the bacterium liquid wherein, forming in step 1) be 6,000 ten thousand/more than ml bacterium.
Wherein, step 2) in, described crudefiber crop raw material is flax, ramie, yellow bluish dogbane or sisal hemp.The described swollen time is 10-12h.
Wherein, the biological degradation temperature described in step 3) remains on 35-40 DEG C, time 32-36 hour.The mass ratio of the raw material after discongesting and bacterium liquid is 1:7-9.Described steam sterilizing is water at atmospheric pressure steam sterilizing 10-30 minute.
Further, step 2) in soak soak solution after raw material through flocculation, precipitation, supernatant liquor recycling, the fermentation of throw out input methane-generating pit produces biogas.
The advantage that biological method provided by the invention is prepared fiber is: 1) free from environmental pollution: waste liquid directly changes into organic fertilizer, reaches zero release, and zero pollutes.2) biological method can play a protective role to fiber, and compared with traditional chemical process, present method can all reclaim full fiber and half fiber, has therefore improved yield.3) biological method is degraded under normal pressure, energy-conservation, reduction of discharging, low-carbon (LC).4) production cost is low, and economic benefit is high.
Byproduct of the present invention is transported to settling tank flocculation, precipitation, and supernatant liquor returns to second stage employ, remakes presoak and uses.In throw out, contain the nutrient for plants such as abundant gas chromatography and N, P, K, throw out mixes with old bacterium liquid (the raw material thickness bacterium liquid of repeatedly degrading, also contains N, P, K, Fe and trace element) again, acidifying, then together enter in marsh gas fermentation pool, produce biogas.By the Boiler Ash mixing granulation of natural pond slag, natural pond liquid and pulverizing, granulation fertilizer, finally dispatches from the factory, and realizes zero release.
The present invention is by the biological bacteria that provides above-mentioned contriver to obtain through long creation work, the further perfect cellulosic technology of existing preparation, reduce the reaction times, improved the purity and the yield that make fiber, this technology can be applied on a large scale in actual production.Applying biological bacterium of the present invention at short notice degrading plant obtains fiber, and byproduct twice transformation becomes biogas, and biogas coal supply, gas boiler for dual purpose combustion heating are saved coal consumption.Finally, natural pond slag is made organic fertilizer, has formed the economic circulation new model of " material organic transformation ", reaches no waste discharge, namely zero release.Fundamentally solve a pollution difficult problem for chemical preparation fiber of the prior art.Energy-saving and emission-reduction, water-saving, has reduced production cost, has improved the rate of utilization of material.
