Abstract
The invention discloses a preparing method for anti-wrinkle flax fabric, which comprises the following steps: 1), enabling liquid ammonia to react with cellulose I of flax fabric to obtain cellulose II; 2), heating the cellulose II obtained in the step 1) to obtain cellulose III; 3), removing ammonia gas and cleaning the residual ammonia gas on the surface of the fabric; 4), adjusting the pH value of the fabric to the range from faintly acid to alkalescence, so as to obtain the anti-wrinkle flax fabric. Further, the invention discloses a method for preparing the fabric into a textile. According to the fabric provided by the invention, the uniform reflection of the flax textile to light rays is strengthened, the elasticity and strength are improved, and the hand feeling and dimensional stability are improved, so that the purpose that the flax textile can be washed and worn is achieved finally.
Description
Technical field
The present invention relates to a kind of crease-resistant flax fabric and corresponding flax crease resistant fabric preparation method, belong to the textile material field.
Background technology
Flax is a kind of common fibrous material, and multiplex in clothing manufacture field, the characteristics such as native cellulose fibre is ventilative owing to having, moisture absorption, nice and cool, antibiotic, gloss is soft have been subject to extensive welcome on market.
But sodolin is due to flax material self, also exist such as high, the easy wrinkle of crystal region, the number of drawbacks such as feel is poor, dyeing Dry Sack rate is low, washing shrinkage is unstable, these defects have all caused very large puzzlement to manufacturer and consumer.
Summary of the invention
For the defect of prior art, the invention discloses a kind of crease-resistant flax fabric preparation method, can be so that NH by method of the present invention
3be penetrated into molecule moment that cellulose fibre is inner carries out expanded complexing with fiber, hydrogen bond in the linen fibre lattice is rearranged, the form of linen fibre and structure are again plastic, overcome the defect of traditional flax fabric, made sodolin there is the multiple effects such as non-ironing, soft, that washing shrinkage is little and stable.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of preparation method of crease-resistant flax fabric, comprise the steps: 1) by the cellulose I of liquefied ammonia and flax fabric, reaction obtains cellulose II; 2) heating steps 1) the gained cellulose II obtains cellulose III; 3) remove ammonia and clean fabric remained on surface ammonia; 4) adjust fabric pH value to faintly acid to alkalescent, obtain crease-resistant flax fabric.
In above-mentioned preparation method, the method that obtains liquefied ammonia is not restricted, and mode is for first to be filled with nitrogen in air accumulator usually, because gas density is poor by the Bas Discharged tank body, prevents from filling after ammonia because the air existence can be blasted; After Bas Discharged, in tank body, be filled with ammonia, pressurization makes the ammonia liquefy ammonia of gaseous state.
Adopt alternate manner, it is also feasible for example directly buying canned liquefied ammonia.
Traditional flax fabric, i.e. linen grey cloth, its cellulose is native cellulose I, structure is CELL-0H, adds liquefied ammonia that following reaction can occur:
The cellulose of the flax fabric obtained through this processing becomes the mercerising fiber, and cellulose II, can be both that the ammonification cellulose I can be also the ammonification cellulose II.
The reaction condition of above-mentioned reaction can be adjusted according to actual amount, preferred steps 1) reaction condition be reaction pressure 8-30KPa.Thereby ammonia is input to liquefied ammonia manufacturing and processing equipment fluid-tight mouth and thereby flax fabric makes fabric compregnate ammonia gas react under above-mentioned reaction pressure from tank body.
Wherein, described step 2), under heating condition, the moment gasification of liquid ammonia is combined with linen fibre, following reaction occurs and form NH
3-CELL II (being cellulose III):
Wherein, reaction condition is heating-up temperature 60-80C, reaction time 1-2min.
After above-mentioned reaction completes, remaining ammonia is reclaimed by retracting device; The flax fabric that gained is consisted of to cellulose III is washed, and removes fabric remained on surface ammonia.
Wherein, eluting temperature is preferably 60 ℃.
After said process completes, adopt common pH adjusting agent to regulate the Acidity of Aikalinity of fabric, adjusting fabric pH is 6-8.
By said method, make linen fibre internal crystallization disorientation through this expanded complexing, discharge internal stress, make the strong rearrangement of intermolecular hydrogen simultaneously, thereby increased the even reflection of sodolin to light, and increased elasticity, intensity, improved feel and DIMENSIONAL STABILITY.
Further, the applicant has invented the resulting crease-resistant flax fabric of said process for the preparation of the method in flax crease resistant fabric by a large amount of technical studies, comprise the steps: linen grey cloth is obtained after Liquid Ammonia Treatment crease-resistant flax fabric, then to its processing of dyeing, carry out RESIN FINISH after dyeing.
Wherein, described dyeing is processed and is referred to that the mode by preliminary drying, vapour steaming colour fixing is cured in fabric the REACTIVE DYES that adopts required color by it; Adopt RESIN FINISH to improve feel and the wash and wear effect of facing fabric.
Further, said process also is included in the front step of linen grey cloth being carried out to pre-treatment bleaching and mercerising of Liquid Ammonia Treatment, by carrying out bleaching and mercerization finish, can make fabric have better color.
Wherein, described pre-treatment bleaching comprises that the employing sodium hydroxide solution carries out kiering, adopts dilution heat of sulfuric acid to carry out pickling, adopts clorox to carry out chlorine and floats, and adopts hydrogen peroxide to carry out oxygen and floats, then washing
Wherein, described mercerising refers to that the sodium hydroxide solution by higher concentration carries out the short time rapid soaking.
Wherein, according to the difference of processing mode, the RESIN FINISH mode is divided into two kinds, and a kind of RESIN FINISH mode is dry crosslinking, and the fabric after dry crosslinking is baked, tentering and preshrunk, gets product; Another kind of RESIN FINISH mode be that tide is crosslinked, and the fabric after tide is crosslinked passes through and banks up, washing, tentering, preshrunk, gets product.
By above-mentioned improvement, the present invention processes these two processing methods by liquid ammonia finishing and RESIN FINISH and unites two into one, and produces significant cooperative effect, makes sodolin reach the wash and wear effect, has obtained significant technological progress.
