Description
Technical field
The present invention relates to a kind of linen fibre and spin front chemical modification Degumming method, belong to the linen fibre field of coming unstuck.
Background technology
Ultimate flax fibre length is short, only has 15-20mm, can't spin by filament, can only be with bundle fiber state (process of fiber) as textile raw material.Except cellulose, also have hemicellulose, lignin, pectin, adipocere matter and the ash accompaniment that grades in flax process of fiber, ultimate flax fibre is bonded together by these accompaniments.Usually weaving is as follows with the preliminary working process of linen fibre: flax straw-dipping (retted fibre)-drying-health-broken stem-scutching-scutched line and noil.Scutched line is through obtaining comb growth fiber crops and machine cast tow after the combing, and as the spinning raw material, wherein wet spinning is mainly adopted in long bast fibre spinning, and tow system adopts dry method to spin.The long numb wet spinning of flax adopts special bast-fiber spinning apparatus take scutched flax as raw material, first scutched flax is made rove by combing, then comes unstuck in the mode of rove kiering, spins under the fiber hygrometric state.Flax wet spinning has avoided causing owing to flax process of fiber is thick and stiff the spinning hard problem, and number and the quality of flax spun yarn have been improved to a certain extent, but the method complex process, processing cost is high, and can only process flax pure yarn, product structure is more single, is unfavorable for new product development.Flax dry method short spinning process generally be take machinery by force the Noil of Flax of combing as raw material, produce at cotton spinning apparatus, can process with other fiber blends, but owing to Noil of Flax length, fineness disperse large, spinnability is relatively poor, generally can only process the low count linen yarn about 20s, product specification is low.
Summary of the invention
The objective of the invention is to solve the problem that the linen fibre spinnability is poor, product variety is single, provide a kind of blowdown flow rate that comes unstuck linen fibre few, that can realize the high branching of flax product to spin front chemical modification Degumming method.
In order to achieve the above object, the invention provides a kind of linen fibre and spin front chemical modification Degumming method, it is characterized in that, may further comprise the steps:
(1) alkali preliminary treatment: under the room temperature linen fibre is immersed in the NaOH solution of 20-150g/L dipping 10-120min;
(2) squeezing: will place squeezer to squeeze through the pretreated linen fibre of alkali, and remove behind the unnecessary alkali lye stand-by;
(3) etherification modified: with through the squeezing after linen fibre put into high-temperature high-pressure reaction kettle, and etherifying agent between 20-80 ℃ in mass ratio 0.2-2.0 carry out etherification reaction, the etherification reaction time is 30-120min;
(4) washing;
(5) chemical Degumming is processed: adopt alkali-oxygen one bath, linen fibre after washing is come unstuck, cooking liquor chief component: naoh concentration 10-50g/L, hydrogen peroxide concentration 2-20g/L, sodium silicate silicate 1-10g/L, sodium sulfite 1-10g/L, bleeding agent consumption 1-10g/L, digestion time 90min, 90 ℃ of boiling temperatures, bath raio are 1: 5-1: 20;
(6) washing and dewatered drying obtain the finished product linen fibre.
Preferably, described water-washing step for concentration be in 10% the glacial acetic acid with etherification modified rear linen fibre in free alkali, then use the deionized water washing and filtering, be washed till pH value 7.0.
Preferably, the etherifying agent in the described etherification modified step is epoxides.
Preferably, described epoxides is expoxy propane.
Preferably, the bleeding agent in the described chemical Degumming treatment step is penetrating agent JFC.
The present invention has overcome the shortcoming that traditional linen fibre spinnability is poor, product variety is single, and realizes the high branching of flax product.The advantage that the present invention has is: (1) carries out etherification modified processing to linen fibre first before chemical Degumming, makes the reaction of linen fibre and etherifying agent generate water-soluble cellulose ether, Effective Raise colloid clearance and linen fibre separate degree of refinement; Therefore (2) the cellulose ether water soluble that generates after the linen fibre etherificate can be removed the part colloid by the method for washing, thereby alleviates the rear road pressure that comes unstuck, and road degumming and bleaching consumption of chemical agent after effectively reducing, reduces the blowdown flow rate that comes unstuck; (3) the linen fibre fineness that adopts etherification modified Degumming method to make is thin, and whiteness, intensity are high, are fit to processing high-count flax textiles, realize the high branching of flax product, have a good application prospect in high-grade clothing, a family textile fabric field.
The specific embodiment
Implementation technological process of the present invention: alkali preliminary treatment---squeezing---etherification modified---washing---chemical Degumming---washing---dehydration---oven dry.
The present invention relates to a kind of before spinning process to linen fibre carry out first etherification modified, then carry out chemical Degumming to improve the method for flax fibre quality and spinnability, the method can obviously improve fineness and the whiteness of flax process of fiber, makes the rescutched tow that makes be applicable to process the pure spinning of high-count flax and blended yarn.
Implementation step of the present invention is:
(1) alkali preliminary treatment: take by weighing the certain mass linen fibre, under room temperature, flood 10-120min in the NaOH solution of immersion 20-150g/L, by alkali lye effect stripping part hemicellulose and impurity, make simultaneously fiber generation swelling, create favorable conditions for rear dao is etherification modified;
(2) squeezing: will place squeezer to squeeze through the pretreated linen fibre of alkali, and remove behind the unnecessary alkali lye stand-by;
(3) etherification modified: the linen fibre after will squeezing places high-temperature high-pressure reaction kettle, be evacuated to and be negative pressure in the reactor, 0.2-2.0 drops into etherifying agent in reactor in mass ratio, starting the agitator stirring makes etherifying agent fully contact with fiber, then be warming up to 20-80 ℃, take out linen fibre behind the stirring reaction 30-120min; (under above reaction condition, the hydroxyl on the linen fibre can generate cellulose ether with the etherifying agent reaction, and hydrogen bond action weakens between fiber molecule, and the simultaneously introducing of ether can improve the separating degree of flax process of fiber in aqueous medium.The present invention utilizes the solubility of above cellulose etherificate principle and cellulose ether, by the etherification reaction of appropriateness, reduces active force between linen fibre, road colloid clearance and the fibre separation index in the process of coming unstuck after improving.)
(4) washing: with concentration be in 10% the glacial acetic acid with linen fibre in free alkali, then use the deionized water washing and filtering, be washed till pH value 7.0;
(5) chemical Degumming: adopt alkali-oxygen one bath, linen fibre after etherification modified is come unstuck, cooking liquor chief component: naoh concentration 10-50g/L, hydrogen peroxide concentration 2-20g/L, sodium silicate silicate 1-10g/L, sodium sulfite 1-10g/L, bleeding agent consumption 1-10g/L; bath raio is 1: 5-1: 20; digestion time 90min, 90 ℃ of boiling temperatures.
(6) washing, dehydration, oven dry: get the finished product linen fibre.
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
