The present invention relates to a kind of method of handling the viscosity cotton, its objective is the viscosity of reduction through the cotton fiber of this processing.More particularly, the present invention relates to handle the viscosity cotton by using bacterium.
Cotton is textile industry one of the raw material of normal use.The world wide production of estimating cotton fiber is annual about 2,000 ten thousand tons.Produce cotton about 20%, approximately annual 400 ten thousand tons, polluted by sugar, form so-called viscosity cotton.Cotton fiber may be polluted by the insect honeydew, the latter is mainly by two kinds of polyphagy homopterans (polyphage homopter insect), i.e. the saccharification excreta of aphid (cotten aphid (Aphis gossypii)) and trialeurodes vaporariorum (white fly) (Bemisia tabaci (Bemisia tabaci)) secretion.
In textile industry, producing and handling in the different step of cotton fiber, the viscosity cotton is caused serious problem.Cotton viscosity has injurious effects to preparation and spinning method.In fact, the existence of honeydew has hindered the proper operation of preparation machine: bale breaker, carding machine ..., can cause the latter's machinery to stop up, need to implement cleaning completely.Similarly, cause lead the winding in a thread unit (drawingunits) (belt (straps), cylinder (cylinders)) of cotton fiber from the viscosity of honeydew sugar, cause the breakage of rove or yarn (yarns) and the reduction of gained yarn quality (amount of cotton knot and other irregularities increases) at roving frame and spinning frame.
Many solutions that are used to reduce cotton viscosity have now been proposed.
In industrialized country, especially in the U.S., the cotton producer is by the potential source of controlling viscosity as possible of cultivating with the pesticide treatments cotton.This solution only part satisfied required: the result who is obtained depends on the amount of the processing of enforcement, before results the last date of handling, reach the difficulty of the insect that is positioned at the low surface of leaf.And this solution causes severe impairment to environment.
Another kind method is by find the means to save the situation to problem of viscosity at results post processing cotton fiber.According to these thinkings, a lot of processing methods are known:
The heat treatment of-cotton fiber is according to file EP196449;
The mechanical treatment of-cotton fiber is according to file US5,153,968;
The hot mechanical treatment of-cotton fiber is according to file EP344631;
The Electromagnetic Treatment of-cotton fiber is according to file EP350669;
The enzyme of-cotton fiber is handled, according to file EP622487.
File EP622487 has described with comprising the composition that is selected from following at least a enzyme the viscosity cotton is carried out the enzyme processing: transglucosidase, pectase, alpha-galactosidase, these enzyme sources are in aspergillus (Aspergillus) fungi.Described enzymatic compositions was used in (by spraying the solution of described enzyme) and/or results backs (it is immersed in the body lotion that comprises 4% described enzyme solutions) before the processing method that reduces cotton viscosity was included in and gathers in the crops on cotton fiber.
As if this processing of viscosity cotton fiber especially in its " selecting scheme after the results for use ", be difficult to be applied on plant-scale cotton.And, before results, spray enzyme and should be accompanied by lasting cotton field irrigation, because these enzyme require water act on its substrate (being present in the carbohydrate on the cotton fiber).At last, because the enzyme price that the method chapter of this processing viscosity cotton uses is higher, expectation can't realize generally using.
The present invention proposes the suggestion of the shortcoming that overcomes the cotton processing method of known viscosity.
The objective of the invention is to propose a kind of biotechnology processing method that is intended to reduce cotton viscosity, this method is convenient to use, not too expensive, to environment without any negative effect, and can be in a large amount of cottons after handling results on the commercial scale.
According to first aspect, the present invention relates to a kind of method of a large amount of processing viscosity cotton fibers, the viscosity that it is intended to reduce described fiber is characterized in that may further comprise the steps:
A. by spray, preferably by the waterborne suspension that the sprays bacterium equably described cotton fiber of described microbionation, so that reach the gained humidity (humidity) of up 16%;
B. with the cotton fiber of compressed package form preservation through this processing;
C. allow the bacterium that is inoculated at room temperature act on significantly at least about a week.
" humidity of gained " expression is added the natural water that the bale of cotton of the humidity percentage (promptly considering to spray the loss of water during handling) that truly provides is provided by cotton fiber of the present invention to it and is obtained (about 8%).
In order to obtain ideal results, promptly give the degraded of the sugar of viscosity to cotton, determine condition of storage according to duration and storage situation.Between 15-20 ℃, obtain this result in room temperature storage one in week, but depend on local weather condition, can be in longer or time that may be shorter this result of acquisition.
In preferred alternate embodiment, be 8-13% according to the gained humidity in the bag of the inventive method processing.The waterborne suspension of bacterium comprises at least 106 bacterium colony forming units in every ml water.The bacterial concentration of being inoculated in described bag is the treated cotton at least 10 of every gram
5Individual colony forming unit.
Applied waterborne suspension comprises and is selected from following bacterium in the method for described processing viscosity cotton: lactobacillus (Lactobacillus), Pediococcus (Pediococcus), Bifidobacterium (Bifidobacterium), lactococcus (Lactococcus), Leuconostoc (Leuconostoc), enterococcus spp (Enterococcus) and streptococcus (Streptococcus).In representational mode, that these bacteriums can metabolism be found on pending cotton fiber, especially be present in sugar in the insect honeydew.According to one embodiment of the invention, this waterborne suspension comprises the bacterium that is selected from down group: Lactobacillus plantarum (Lactobacillus plantarum) and Lactobacillus casei rhamnosus (Lactobacillus casei rhamnosus).Preferably, described waterborne suspension comprises the bacterium that is selected from Lactobacillus casei rhamnosus R0011 and the Lactobacillus plantarum R1012 bacterial strain.
According to second aspect, the present invention relates to a kind of freeze-dried powder that comprises aforementioned bacterium, for the suspension that obtains to be used to spray, only need this powder dissolution in water.
According to the third aspect, the present invention relates to a kind ofly to comprise the described freeze-dried powder of determining amount x, be used to inoculate the bag of the viscosity cotton of a certain amount of y.
Now describe the present invention in detail.
The application relates to a kind of method of handling the viscosity cotton, its objective is the viscosity that reduces cotton fiber, and optimizes the machinability through the cotton fiber of this processing thus.Cotton machinability means cotton fiber experience egrenation, combing, spinning, dyeing (dying), weaves operation to obtain the ability of high-quality cotton yarn/fiber/fabric.

Embodiment 1. is present in carbohydrate on the viscosity cotton fiber by bacterial digestion
According to API50CHL method (BIOMERIEUX), the 24 strain bacteriums of collecting from LALLEMAND are carried out the test that sugar utilizes.According to this test, might confirm that specific bacterial strain utilizes the ability of different sugar and polysaccharide.The bacterial strain of test belongs to lactobacillus, sheet coccus, Bifidobacterium, galactococcus, leukonid, enterococcus and streptococcus.
In the bacterial strain of test, have only those bacterial strains that uses at least two kinds of sugar in sucrose, trehalose and melezitoses, i.e. 9 bacterial strains are in the test of growing with sucrose or in trehalose or the MRS culture medium with melezitose replacement glucose.Cultivated 24 hours down at 30 ℃, assess their growth rates on these culture mediums by measuring turbidity or optical density in time.Keep two kinds of bacterial strains that demonstrate optimum growh under these conditions: Lactobacillus casei rhamnosus R0011 and Lactobacillus plantarum R1012 are used for the application testing on the cotton fiber.
These two kinds of bacterial strains are kept at CNCM (state-run microbial preservation center (Collection Nationale de Cultures de Microorganismes)) with following sequence number:
-Lactobacillus casei rhamnosus R0011 (Lactobacillus casei rhamnosusR0011): CNCM I-1720;
-Lactobacillus plantarum R1012 (Lactobacillus plantarum R1012): CNCMMA-18/50.
As known to, these bacteriums do not have pathogenic.
Embodiment 2. uses the method for handling the viscosity cotton fiber in laboratory scale
Use the effect of the parcel research bacterial treatment of 50g to the viscosity cotton.This parcel has the density identical with standard-sized bag.
In the phase I, the purpose of preliminary test is to determine the best mode of inoculation and moistening this parcel.Tested following two kinds of inoculation methods:
-water is injected parcel.The result is unsatisfactory, because highdensity cotton fiber makes the very difficulty that penetrates of pin in the parcel, and has stoped the even dispersion of liquid in little bag of injecting;
-water is sprayed onto on the cotton fiber; In this alternative, open parcel, at fiber
Upward even spray solution, and then sealing parcel and maintenance are at room temperature.
As previously mentioned, on the cotton parcel of 50g, the bacterium that belongs to Lactobacillus casei rhamnosus and Lactobacillus plantarum kind is tested the effect of cotton viscosity.Humidity is high more in the bag, and the metabolic activity of the bacterium of inoculation is big more, and reduces fast more through the cotton fiber viscosity of this processing.Notice that under the situation of cotton drying, the activity of institute's inoculated bacteria reduces before the present invention handles.
Gained humidity in the preferred parcel should be 8-13%.
Bacterial treatment according to viscosity cotton fiber of the present invention does not influence the cellulosic extent of polymerization that enters the cotton fiber composition.
Gained humidity 16%, 21 ℃ of down lasting weeks are with every gram cotton 2.5 * 10
6The amount of individual colony forming unit uses Lactobacillus plantarum suspension to obtain optimal efficacy.Stick test by the routine of treated cotton and confirmed this result.
Embodiment 3. handles the method for viscosity cotton fiber with the sizable application of pilot scale station
Next carry out pilot scale test, comprising with every gram processed cotton 4 * 10
6The cotton fiber of the bacterial treatment high viscosity of the concentration appliable plant lactobacillus class of individual colony forming unit, the gained humidity in the bag is 9.5-12%.Use roving frame and ring ingot spinning frame will carry out standard spinning operation then, perhaps further use centrifugal principle (machine openend) to be rotated the spinning operation through the cotton fiber of this processing.The gained result is positive, and it shows the viscosity complete obiteration through the cotton of this processing.The quality of the yarn of gained is not subjected to the influence of this processing thus.
Even additional test shown at room temperature cultivate one month after, increase the appearance that 5% humidity can not cause mould, hence one can see that does not need subsequent treatment to stop microbial growth.
The industrial treatment method of embodiment 4. viscosity cotton fibers
On commercial scale, use 6 bale of cottons in the test of processing viscosity cotton with following 3 kinds of levels of adhesion:
I. low viscosity: bag S6 and S7;
Ii. middle viscosity: bag S8 and S9;
Iii. high viscosity: bag S1 and S5.
Before processing, mix two bags having near levels of adhesion, then will be through the gross weight separated into two parts of every kind of levels of adhesion of this gained, so that can there be and not have the spinning test of bacterial treatment.
Inoculate in 6 bags that obtain through this 3 by the waterborne suspension that sprays microorganism.From comprising the freeze-dried powder supending that lactic acid bacteria, especially described bacterium belong to the bacterium of Lactobacillus plantarum and Lactobacillus casei rhamnosus.Described freeze-dried powder is put into bag with the weight of determining, for example the bag of 100g.Find that every bag of 100g is the cotton bacterium dosage required and abundance of inoculation 200kg.With the content of bag (2 liters of clean waters use the 100g freeze-dried powder) soluble in water; Stir powder-aqueous mixtures fully.Following step is at room temperature to dissolve the suspension in water that at first obtains; The volume that adds entry in this dilution step depends on the weight of pending viscosity cotton and the humidity of expectation.For example, in order in the 200kg bag, to obtain 10% humidity, suspension (2 liters) is dissolved in 20 premium on currency.For fear of any reduction of bacterial activity, should in the enough short time, will be sprayed onto on the pending cotton fiber through the diluted suspension of this gained.
