Abstract
The invention discloses a medium or dark shade fabric and a production method thereof; the fabric is a woven or knitted fabric at least comprising terylene and spandex, wherein the spandex fiber content takes about 3-20%; the fabric L value is 12-65; in the dry cleaning color fastness of the fabric that measured according to the JISL0860 standards, the variable color is above 3-4 level, staining is above 3 level, and washing lotion pollution is above 3 level. A hot setting and sour water washing mode is added after dyeing, thus effectively improving the dry cleaning color fastness of the medium or dark shade fabric; sorting setting temperature is controlled so as to stabilize the improved effect, so the fabric has excellent dry cleaning color fastness.
Description
Technical field
The present invention relates to dark fabric and production method thereof in one, it is specifically related to middle dark elastic fabric and the production method thereof of a kind of high dry-cleaning colour fastness.
Background technology
It is well known that the color at major part garment material initial stage all compares bright-coloured, but after being through the conditions such as friction or Exposure to Sunlight, color relation can change, and there has been proposed corresponding solution to solve these colour fastness problems. Such as, by the good dyeability of positively charged ion terylene and dye penetration in CN200810062408.6, it is ensured that adopt the colorfastness to rubbing of the knit fabric of terylene and spandex. And for example, uvioresistant auxiliary agent is used to improve the light fastness of fabric when CN201310581010.4 being shaped by Final finishing. But above-mentioned patent all fails to solve the dry-cleaning colour fastness problem of fabric.
Need to add the dry cleaning composition that oil or zellon and so on performance is relatively given prominence to during dryclean, perhaps within can accomplishing criterion of acceptability for light color fabric, but middle dark fabric just differs up to standard surely, especially the elastic fabric of spandex is contained, the criterion of acceptability that every colour fastness often can not reach more than 3 grades is dry-cleaned according to what JISL0860 standard recorded, even if by methods such as washing reinforcement or fixation, perhaps dry-clean variable color, dry-cleaning staining can accomplish qualified value 3 grades, but for dry-cleaning washing lotion pollution project often only reach 1-2 or 2 grade.
In addition, although also Lu Luxu is continuous carries out a series of product innovations for this project of dry-cleaning in part dyestuff producer, improve drycleaning with the use of special dyestuff, but these dyestuffs often price all costly, the stability of color is also good not as the colour stability of conventional dyestuff.
Summary of the invention
It is an object of the invention to provide a kind of working method simple, with low cost, there is middle dark fabric and the production method thereof of good dry-cleaning colour fastness.
The fabric of the present invention is the woven or knitted fabrics at least containing terylene and spandex, wherein the content of spandex fibre is 3%��20%, and the L value of this fabric is 12��65, in the dry-cleaning colour fastness of this fabric recorded according to JISL0860 standard, variable color more than 3��4 grades, staining more than 3 grades, washing lotion pollute more than 3 grades.
The working method of the present invention is simple, the dry-cleaning colour fastness of middle dark fabric is effectively improved by the mode adding drying and shaping after dyeing, acidity is washed, and by arrangement setting temperature control is stabilized is improved effect, gained fabric has superior dry-cleaning colour fastness, and such fabric can meet the dry-cleaning colour fastness requirement of some high-end apparel brand completely.
Embodiment
Spandex content is the middle dark fabric of 3%��20%, owing to employing the dyestuff of more amount, spandex more or less also can adsorb a part, too big impact is not perhaps had for the washing colour fastness of routine, sweat proof colour fastness, colorfastness to rubbing etc., but for employing the dry-cleaning mode of the stronger zellon of solvability or oil, be attached to spandex surface and inner dyestuff can be peeled off again, cause fabric variable color, staining; Even can be dissolved in dry-cleaning liquid causes washing lotion to pollute, and finally causes dry-cleaning colour fastness defective. And this phenomenon can't produce deviation because of the length form of other fibre compositions in fabric or fiber, as long as containing terylene composition in fabric, and need dispersion dyeing, the composition of spandex reach 3%��20% even higher when, will exist dry-cleaning colour fastness problem.
In the middle dark fabric of the present invention, polyster fibre is one or both in ordinary polyester fiber and modified polyester fibre.
Consider the comfortable property of fabric, it is preferable that also containing cotton or viscose fiber except terylene and spandex, its content is 10%��40%.
The production method of the middle dark fabric of the present invention, adopt the woven or knitting grey cloth at least containing terylene and spandex, wherein the content of spandex fibre is 3%��20%, comprises and obtains product as follows: dyeing �� alkaline reduction washing �� drying and shaping �� acidic reduction washing �� arrange sizing. Here dyeing is dispersion dyeing, and processing conditions is the conventional dispersion dyeing condition of ordinary polyester. The weave construction of fabric is not particularly limited.
After wherein dispersion dyeing completes, generally only carry out one alkaline reduction washing, but this for dry-cleaning colour fastness or inadequate. Present invention utilizes the feature of dispersion dyeing, first drying sizing is carried out again after primary alkali reduction washing, dye sublimation polyster fibre and the infiltration of spandex fibre slight internal entered is out so that it is is attached to fiber surface, carries out acidic reduction washing afterwards again. Drying and shaping temperature preferably 160��180 DEG C. Acidic reduction washing mainly plays two effects: the dyestuff eccysis that distillation is out still attached to fiber surface is gone by (1), improves colour fastness further, especially dry-cleans the washing lotion pollution project of colour fastness; (2) this kind condition more close with dispersion dyeing environment is washed by acidic reduction, and the water-washing method that alkalescence washing is more gentle relatively, it is possible to stable color greatly, the color change that unlikely generation is bigger.
The mode usually adopting and going straight up to the highest temperature is cleaned in alkaline reduction, is incubated 20��60 minutes after arriving the highest temperature 80��95 DEG C. With medicament is made at least to comprise vat powder 3��10g/L, caustic soda or soda ash 1��6g/L. After highest temperature insulation terminates, it is cooled to 60��70 DEG C and carries out row's feedwater, and then carry out 2��4 clear water washings, each 2��5 minutes, complete alkaline reduction and clean.
Acidic reduction cleans the mode usually adopting and going straight up to the highest temperature, is incubated 20��60 minutes after arriving the highest temperature 80��95 DEG C. With medicament is made at least to comprise Glacial acetic acid 1��5g/L, acidic reduction agent 1��5g/L. After highest temperature insulation terminates, it is cooled to 60��70 DEG C and carries out row's feedwater, and then carry out 2��4 clear water washings, each 2��5 minutes, complete acidic reduction and clean.
In order to prevent the arrangement of last excessive temperature from shaping so that the distillation again of the dyestuff permeated into precipitates out, the significantly result of impact dry-cleaning colour fastness, therefore, the temperature arranging sizing is not preferably higher than 190 DEG C.
Embodiment
The testing method of each performance involved in the present invention is as follows.
(1) colour fastness is dry-cleaned
The A method in " fabric is to the test method of dry-cleaning colour fastness " in JISL0860-2008 is adopted to test. Choose and represent sample and put into cotton bag together with Stainless Steel Ball, be placed in zellon stir, the de-liquid of extruding, dry, evaluate the variable color of sample and the staining of adjacent fabric with gray scale. Filter solvents projects light with blank and compares, and evaluates the painted of solvent with gray scale.
(2) L value
By sample 21 �� 1 DEG C (70 �� 2) 65 �� 2% relative humidity placement several hours under standard atmospheric conditions, DATECOLOR equipment is used to carry out the test of fabric L value afterwards.
