Abstract
The invention relates to textile fiber biological de-gumming method. It includes the following steps: adding 100ml distilled water in 500ml triangle baker; adding 4g hemp skin as 1:25 bath ratio; adding 0.8g K2HPHO4.3H2O analytically pure to adjust pH; sterilizing at high pressure and 121 degree centigrade for 20 minutes; washing cultured bacteria into beaker by physiological saline to make its density reach 2 billion/ml; sealing; setting on oscillator to oscillate at 42 degree centigrade for 24 hours with 150r/min; sterilizing at 121 degree centigrade for 20min after de-gumming; and testing residue stock rate after washing.
Description
Technical field:
The present invention relates to a kind of Degumming method of natural plants apocynum fibre, particularly relate to a kind of Degumming method, can be applicable to the processing of natural textile material with biotechnology.
Technical background:
Bluish dogbane has the branch of bluish dogbane and hemp, hemp fiber crops plant height, and branch is few, and hemp stalk is thick, and is drought-resistant and saline alkali is stronger, mainly is distributed in the hinterland, northwest, is the main source of fiber with fiber crops; The strain of bluish dogbane fiber crops is short, and the thin wooden fork of bar is many, and drought-resistant and saline alkali is not so good as hemp, in the scope to Xinjiang distribution is all arranged from coastal west with east northeast in the Changjiang river.Having many uses of bluish dogbane, leaf juice can be cooked beverage, and leaf can be made tea; Stalk and numb micromicro are with papermaking; The fiber that extracts from numb skin can be made clothes, can also do fishing lines, leather line etc., and also be a kind of extraordinary medicinal material.Apocynum is in all-natural product, and quantity is very big, does not have the problem of pollution by pesticides and lack of material.Apocynum fibre is described as " king of wild fiber " by the crudefiber crop expert, it shows as, and to spread out harl much thin than ramie, and the gloss of silk is arranged, well-pressed, the cotton softness of fiber crops, and the malleability of suede, this is that other any textile raw material all can not be compared.And can carry out blending with cotton, silk, hair and chemical fibre, also can carry out pure spinning, gained textiles drapability, antistatic behaviour are better, and product is well-pressed, and moisture absorption is loose wet fast, compares with wearing COTTON FABRIC, can make human body sensory more dry and comfortable.In addition, the bluish dogbane textiles also has the advantage of antibacterial, mildew-resistant, deodorization.The chemical composition of bluish dogbane fiber crops skin comprises cellulose, hemicellulose, pectin, the hydrotrope, lignin, adipocere matter six classes, and wherein the material except that cellulose is referred to as colloid.At occurring in nature, there are a lot of microorganisms can utilize colloid to be its carbon nutrition source, with colloid decomposition and inversion such as pectin substance, hemicellulose and lignin is simple lower-molecular substance, therefrom obtains required nutriment of vital movement own and heat energy, finishes coming unstuck of flax fibre simultaneously.
Apocynum fibre is by removing the colloid in the numb skin, keeps that cellulose obtains, and the process of removing colloid is called as comes unstuck.The method of coming unstuck has a lot, mainly comprises chemical degumming law, enzyme degumming method, bacterial degumming method and biochemistry combination degumming method.At present, what apocynum degumming adopted is chemical Degumming method, and its shortcoming is that water consumption is big, and the energy consumption height is seriously polluted, the particularly important is the damage of fiber greatlyyer, destroys cellulosic structure and worsens shortcoming such as cellulosic quality.
Purpose of the present invention proposes a kind of method of coming unstuck with biotechnology, the colloid in the numb skin can be removed more than 85%, obtains containing after the fiber of a small amount of colloid, carries out alkali treatment again, just can obtain the good apocynum fibre of spinning property.
Summary of the invention:
In order to realize the foregoing invention purpose, the present invention is from the Tanaka's separation of bluish dogbane fiber crops and obtain efficient degumming bacterium promptly: hay bacillus can be used for coming unstuck of bluish dogbane.Concrete technology is as follows:
The cultivation of the first step, apocynum degumming bacterium:
(1) gets the about 200g of soil of bluish dogbane root, add aquae destilIata sterilis 500ml and stir, leave standstill 30min; Get the about altogether 30g of root of Apocynum venetum L, stem, leaf and numb skin, it is shredded, add aquae destilIata sterilis 150ml, leave standstill 30min after the stirring.Draw supernatant with suction pipe respectively, on the solid medium flat board, splash into two, and on flat board, rule, liquid is evenly disperseed, place constant incubator to cultivate 24h down then at 37 ℃ with getting collarium.
(2) observe to cultivate the bacterium colony that on flat board, grows behind the 24h, according to outward appearance select the hay bacillus bacterium colony and on flat board through repeatedly go down to posterity (select smooth colony: moistening at every turn. glossy. wrinkle is big. the bacterium colony peak height. shape is translucent) until obtaining more stable bacterial strain.
(3) the pure culture bacterial strain that separation is obtained intensive line on the solid medium flat board places constant incubator stand-by after cultivating 24h under 37 ℃.
Second step, apocynum degumming method:
(1) inoculation is come unstuck: add the culture medium of 100ml in the conical flask of 500ml, added numb skin in 1: 20 to 1: 30 by bath raio, add 0.5 to 1g K
2HPO
43H
2O analyzes pure adjusting pH8 to 10, at 121 ℃ of following autoclaving 20min, with physiological saline cultured bacterium in the solid medium surface plate is washed the adding beaker from flat board, makes bacterial concentration in the flask reach 2,000,000,000/ml and seals.Then flask is placed on the oscillator 37 to 45 ℃ of constant temperature vibrations 18 to 36h, frequency of oscillation is 120 to 180r/min.Finish the back autoclaving that comes unstuck, wash and survey residual gum content then.
The present invention compared with prior art, thereby save industrial chemicals, alleviated damage to textile fabric, help follow-up weaving processing.And because this technology uses obligate aerobes to come unstuck, more thorough to the decomposition of colloid, thus alleviated pollution to environment, have high yield, high-quality, advantage such as efficient, energy-conservation, anti-pollution.
Specific embodiments:
Below by specific embodiment the present invention is further elaborated.
The culture medium that adds 100ml in the conical flask of 500ml is put into 4g fiber crops skin by bath raio at 1: 25, adds 0.8gK
2HPO
43H
2O analyzes pure adjusting pH9.1, at 121 ℃ of following autoclaving 20min, with physiological saline cultured bacterium in the solid medium surface plate is washed the adding beaker from flat board, makes bacterial concentration in the beaker reach 2,000,000,000/ml and seals.Then flask is placed on the oscillator at 42 ℃ of constant temperature vibration 24h, frequency of oscillation is 150r/min.Finish the back autoclaving that comes unstuck, wash and survey residual gum content then.
