Abstract
The present invention relates to a preparation method of high-cleavage degree flax fiber, which belongs to the field of textile. Firstly, flax raw materials are degummed by biologic enzymes; then, the degummed flax raw materials are processed by oxygen bleaching at normal pressure, acid and alkali neutralization, softening, baking and moistening to prepare the high-cleavage degree flax fiber. By the preparation method, the cleavage degree of flax fiber is enhanced, and the characteristics of flax are not changed; the cleavage degree is enhanced to more than 2000 from original 400 to 600; the cohesive performance of the fiber is enhanced; the spinnability of the flax fiber is improved; the spinning number (mixed yarn) can be as high as more than 160<N>.
Description
Technical field
The present invention relates to field of textiles, be meant a kind of method for preparing flax fiber in high cleavage degree.
Technical background
It generally is soda boiling, washing, dehydration, shredding, oven dry that flax commonly used is handled, because of the linen fibre that obtains soft inadequately, low, the suitable imitative property of division degree is poor, spinning count is not high, in the production method of the disclosed kenaf-cotton blending yarn of Chinese patent CN93100748.4, with softener it is softened after washing in the linen fibre processing procedure, though improved the flexibility of linen fibre, increased the cohesive force of fiber, improved the spinnability of fiber, but the raw material that it is suitable as low number blending wants to make institute's number that spins to improve and reaches 120
NMore than, its division degree, spinning suiting, coherent all do not reach requirement.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, a kind of preparation method of flax fiber in high cleavage degree is provided, by flax raw material is come unstuck, oxygen floats, soften, dewing, obtain the division degree and surpass 2000 linen fibre, improve the coherent and the spinnability of fiber greatly, can spin high-count (greater than 120 s') blended yarn.Main innovate point be flax raw material earlier through biological enzyme degumming again normal pressure oxygen float, after acid-base neutralization and softening, the oven dry again dewing make, be specially: the preparation method of flax fiber in high cleavage degree is characterized in that:
1) the flax raw material enzyme comes unstuck.Flax raw material is dipped in the aqueous solution that is added with enzyme preparation, and enzyme preparation is made into by pectase and cellulase at 1: 1.
Bath raio 1: 1.3-1.5
Temperature 38-40 ℃
PH 7-7.5
Time 6-7 hour
Enzyme preparation weight: the 0.3%-0.5% that feeds intake
2) normal pressure oxygen floats.
Temperature: the 90-100 ℃ time: 50-60 minute
Contain in the aqueous solution: H
2O
28-10g/L Na
2CO
32-3g/L bubble flower alkali 0.2-0.4g/L
3) acid-base neutralization, softening.
Temperature: the 50-60 ℃ time: 20-30 minute
Contain in the aqueous solution: silicone oil 15-25g/L acetic acid 1-2g/L antistatic additive 0.1-0.2g/L
4) oven dry back dewing.Dewing when treating after flax oven dry that regain reaches 7-8%, workshop moisture temperature is controlled at more than 80%, stacked 45-50 hour behind the overlay film, last machine moisture regain reaches 14-16%, spraying with each component content in the solution is flax raw material weight: 308 silicone emulsion 1-3%, NNO 0.6-1%, paregal O 0.5-0.8%, natrium citricum 0.3-0.5%, distilled water 2-5%.
Because of having a large amount of colloid and impurity on the linen fibre, flax raw material adopts biological enzyme degumming, removes most of colloid, and the sticky point between the fiber is separated, and through the combing of later process, can increase substantially the division degree and the high-efficiency environment friendly of linen fibre; Normal pressure oxygen floats the linen fibre that can make smoky gray and becomes fair and clear glossy, very near the gloss of silk fiber, the adsorptivity of fortifying fibre, the color and the COLOR FASTNESS that are fit to dye the various depths are good, in 90-100 ℃ water temperature, go back residual colloid in part that can be removed and impurity, help the raising of linen fibre division degree; Acid-base neutralization can make the linen fibre softness with softening, and the coherent between the fortifying fibre reduces spinning static, and the spinning suiting that improves linen fibre makes the degree of staining of fiber improve behind the acid-base neutralization, is the garment dyeing service of road, back; Dewing after the oven dry can reduce in the carding process frictional static and to the physical damnification of fiber, strengthen spinning suiting and the powerful spinning row yielding that improves of flax.
Linen fibre after the dewing of the present invention is sold through promptly can be used as the finished product linen fibre behind the circle comb again.
Handle flax raw material with the method for the invention, improved the division degree of linen fibre and do not changed the characteristic of flax, the division degree is brought up to more than 2000 by former 400-600, the coherent of fortifying fibre, improve the spinnability of linen fibre, thereby made the institute's number that spins (blended yarn) height, can reach 160
NMore than.
