A kind of composite flora and prepare the method for textile fibres with it
Technical field
The present invention relates to a kind of textile fibres, particularly relate to a kind of composite flora and prepare the method for textile fibres with it.
Background technology
In recent years, along with the exhaustion day by day of fossil resources, bast-fibre enjoys doting on of human consumer because having the good characteristic such as ecology, environmental protection, and its demand is increasing year by year, the annual speedup 8% of global natural fiber.The maximum feature of bast-fibre raw material is that fibre content is high, and fiber elongated being conducive to 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.
From numb raw material, prepare fiber in prior art, how by chemical process, the waste liquor contamination sublimity that chemical process produces in producing, damage to land, polluted air, and it is high to consume energy, power consumption and water consumption large.Do not meet national energy-saving and reduce discharging policy.Material can not reach Efficient Cycle recycling.Chemicals cannot be separated from waste liquid, and organism and chemicals mix, and organism also cannot be reused, and causes a large amount of loss.
Therefore, be necessary to develop biological fibre technology processed, fundamentally solve an above-mentioned pollution difficult problem, energy-saving and emission-reduction, water-saving, reduce production cost and the rate of utilization of raising material.
Summary of the invention
The object of the invention is the above-mentioned defect of the chemical legal system fiber overcoming prior art, provide a kind of newly prepare fiber biological bacteria.Contriver, by long screening operation, obtains the biological bacteria that can realize foregoing invention object being suitable for preparing fiber.
Particularly, the invention provides a kind of composite flora, it comprises the genus bacillus (Bacillus sp.) that preserving number is CGMCC No.5971, preserving number is the acinetobacter lwoffii (Acinetobacter lwoffii) of CGMCC No.5973, preserving number is the Pseudomonas fluorescens (Pseudomonas fluorescens) of CGMCC No.5974, preserving number be this Wickerhamomyces anomalus bacterium of Wickerhamomyces anomalus(of 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) μm, precipitation is had to be formed.25 DEG C, wort agar inclined-plane is cultivated one month, bacterium colony cheese shape, oyster white, and surface smoothing is not reflective, edge root shape.Corn Meal Agar Dalmau slat chain conveyor, produces pseudohypha).
Described composite flora can be used in preparing textile fibres.
The present invention also provides a kind of method preparing textile fibres, 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:
Genus bacillus: acinetobacter lwoffii: Pseudomonas fluorescens: Wickerhamomyces anomalus is 2-3:1-2:1-2:2-3;
2) Feedstock treating: 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 configured;
Wet sterilization: to be pulled out from bacterium liquid by the raw material after above-mentioned biological degradation, draining, passes into water vapor sterilizing;
The acquisition of fiber: the raw material after sterilizing is carried out one section of corase grind, become fibrous bundle; Above-mentioned one section of corase grind is carried out two sections of fine grindings, makes fibrous bundle be dispersed into single fiber; Screening, be filtered through one section corase grind and two sections of fine grindings after slurries in fibrous bundle, defibrination makes it make single fiber again;
Dry, combing: soaked in warm water by above-mentioned obtained fiber, then oven dry, combing, for the preparation of textile fibres.
Wherein, the density of the bacterium liquid formed in step 1) is 6 × 10
7more than individual/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 30-34 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 the 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 prepares fiber is: 1) free from environmental pollution: waste liquid directly changes into organic fertilizer, reaches zero release, no pollution.2) biological method can play a protective role to fiber, and compared with traditional chemical process, Whole fiber and half fiber can all reclaim by present method, therefore improve yield.3) biological method is degraded at ambient pressure, energy-conservation, reduce discharging, low-carbon (LC).4) production cost is low, high financial profit.
Byproduct of the present invention is transported to settling tank flocculation, precipitation, and supernatant liquor returns second stage employ, remakes presoak and uses.Containing nutrient for plants such as abundant gas chromatography and N, P, K in throw out, throw out mixes, acidifying with old bacterium liquid (raw material thickness bacterium liquid of repeatedly degrading, also containing N, P, K, Fe and trace element) again, 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, make granular organic fertilizer, finally dispatch from the factory, realize zero release.
The biological bacteria that the present invention obtains through creating work for a long time by providing above-mentioned contriver, the perfect further cellulosic technology of existing preparation, reduce the reaction times, improve purity and the yield of obtained 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, biogas coal supply, gas boiler for dual purpose combustion heating, saves coal consumption.Finally, natural pond slag makes organic fertilizer, defines 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, reduces production cost, improves the rate of utilization of material.
For above and other objects of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and coordinate accompanying drawing, be described in detail below.
