Description
Technical field
The present invention relates to the textile dyeing and finishing field, specifically is a kind of desizing and dyeing one-bath process for woven fabric.
Background technology
Increasingly competitive at current dyeing and finishing industry; cost goes up day by day; under the influence of overall situation such as environmental protection pressure increasing; as energy high flow rate; the dyeing and finishing Business survival of high pollution is increasingly difficult; many enterprises have difficulty in taking a step; productivity effect descends; increasing environmental pollution; serious waste of resources; under these circumstances; low as energy resource consumption; the production efficiency height; little " dye-bath retreat method " new technology of environmental pollution just becomes the object that numerous experts and scholars lay siege to research; for many years; each dyeing and finishing industry expert; the engineer never abandoned the research and development to this new technology, but effect is all not satisfactory.
The traditional dyeing and finishing method of woven fabric is to adopt destarch, dyeing two bath methods.Woven fabric destarch principle and purpose:
1, woven fabric employed yarn in weaving process, in process by the fibrous woven resultant yarn, because the basic principle of spinning and the restriction of existing various spinning methods, become sliver to do and certainly existing many filoplumes, it is the major reason of warp end break when causing weaving, simultaneously also because the surface texture of textile fabric commonly used is smooth, the lateral pressure that these fiber surfaces in yarn produce when relying on twisting carries out mutual obvolvent, this cohesive force also is comparatively faint, and this is the another reason that causes warp end break.And the broken end of warp thread usually causes and weaves difficulty, for preventing the generation of this phenomenon, and raising weaving speed, warp thread generally all must be through this process of starching in weaving process for woven fabric, promptly warp thread is immersed slurry and make yarn surface attachment one deck slurry, adjust feel, increase lubricated, fabric is lubricated reduces friction in order to increase in addition, is beneficial to and weaves, and fabric adds some finishes sometimes, and the woven fabric of the different fibers of different cultivars its add all differences again of impurity components such as slurry and contained greasy dirt, in a word, do not compare with grey cloth after the destarch, have following problem without the grey cloth of destarch through the woven grey cloth of strict destarch:
A, grey cloth feel are stiff especially;
B, grey cloth are dirty serious;
C, grey cloth cloth cover are coarse, not careful, out-of-flatness;
D, cloth cover twist not plentiful;
E, have a strong impact on dyeing quality, as cause colouring non-uniform phenomenons such as look flower, look stain, color dot, color spot, barriness, look shallow as direct dyeing.
2, the purpose of destarch be exactly before dyeing in the remover fabric knitting process accompanying on fabric slurry and the part natural impurity of fabric itself.The existence of slurry is very unfavorable to printing and dyeing processing: 1. consume dying material, 2. stain working solution, 3. hinder dying material and contact with surface fiber of the fabric, produce during dyeing and refuse to dye phenomenon, form various quality problems.
Treasured carries out destarch to woven fabric in employing NaoH, the spirit of deoiling, refining agent and the bath earlier of traditional destarch, dyeing two bath methods, and then adopts dyestuff and levelling agent that woven fabric is dyeed, and also will carry out post processing to woven fabric with reduction cleaner at last.
This destarch, dyeing two bath methods have following shortcoming:
One, dyeing and finishing step is more, the dyeing and finishing required time is long, causes cost of labor higher and production efficiency is lower;
Two, water consumption is big, blowdown flow rate is big, consumption TV university, coal consumption are big, causes water rate, charges for disposing pollutants, the electricity charge and coal expense higher, and overall energy consumption is higher.
Up to now, woven fabric realizes that the dye-bath retreat method still is a technical barrier, and reason is as follows:
1, traditional desizing generally has three kinds: 1, alkali destarch; 2, sour destarch; 3, enzyme desizing.More than sour destarch and enzyme desizing can only be applied to certain species slurry and cloth kind in three kinds of technology destarch handle, utility ratio is not high, and the destarch effect is undesirable.The alkali destarch is most widely used, and the principle of alkali destarch is that all kinds of slurries all can swelling in heat alkali liquid, fluffs with the cloth cover adhesion, the part slurry is dissolvable in water in the alkali lye, but with the hot water eccysis, reach the destarch effect, but the swelling thing is present in the words of not getting rid of in the dyeing machine, gathering the back generation congeals, stick in fabric and the dyeing machine, cause quality problems such as specking, and it is bad to cause fabric to move in dyeing machine, cause the wrinkle bar, and the eccysis difficulty.So traditional dyeing must be independent with the destarch operation, wash cloth after the destarch and could continue dyeing.
2, the woven fabric fibre composition mainly contains terylene (polyester fiber), nylon (polyamide fiber) etc., the used dyestuff of they dyeing is respectively DISPERSE DYES, ACID DYES or neutral dye generally speaking, dyeing traditionally, these three kinds of dyeing conditions all need can be painted under solutions of weak acidity or under the neutrallty condition, otherwise certainly will influence Color.And ACID DYES is dyed nylon fabrics, up to now, and the domestic craft embodiment of still being unrealized and dyeing down in alkali condition.
Summary of the invention
The purpose of this invention is to provide a kind of desizing and dyeing one-bath process for woven fabric, it can reduce woven fabric dyeing and finishing step, shortens the dyeing and finishing time, enhances productivity, reduces cost of labor, and reduce overall energy consumption significantly.
Technical scheme of the present invention is such: desizing and dyeing one-bath process for woven fabric, the dyestuff that the color First Astronautic Research Institute for Measurement and Test that will dye according to fabric variety and fabric needs, under normal temperature, dye well woven fabric grey cloth is dropped in the water-bath, and in water-bath, drop into the 1-4% that accounts for woven fabric grey cloth weight the anionic desizing agent, account for woven fabric grey cloth weight 1-2% the agent of anticracking yarn and account for the moon/non-ionic surface active agent of the 1-3% of woven fabric grey cloth weight; Speed with 0.5-2 ℃ of per minutes is heated to 70-100 ℃ with water-bath then, keeps this temperature to add the glacial acetic acid of the 0.2-0.5% that accounts for woven fabric grey cloth weight after 8-15 minute; With per minute 0.5-3 ℃ speed water-bath is heated to 80-120 ℃ then, keeps this temperature with the speed of 1 ℃-4 ℃ of per minutes water-bath to be cooled to 50 ℃-90 ℃ after 20-60 minute, just finish to move back and dye same bath process.
Above-mentioned anionic desizing agent comprises following percentage by weight component: refining desizing agent 45%-55%, soda ash 25%-35% and water 15%-25%.
Above-mentioned anionic desizing agent comprises following percentage by weight component: refining agent 25%-35%, degreaser 25%-35% and water 35%-45%.
Above-mentioned the moon/ionic surfactant pack is drawn together following percentage by weight component: bleeding agent 15%-25%, diffusant 25%-35% and water 45%-55%.
After adopting such scheme, desizing and dyeing one-bath process for woven fabric of the present invention, the anionic desizing agent has excellent acid alkalescence can, and have extraordinary refining, emulsification, oil removing, remove stupid dirt, remove special efficacy such as slurry, can effectively remove woven fabric employed various slurries and greasy dirt in the spinning and the process of weaving cotton cloth, the anionic desizing agent utilizes the melting property by force of auxiliary agent itself, make the dissolving fully in water-bath of various slurries, destroy the chemical property of slurry itself, make its attachment phenomenon that can't congeal once more, dye with bathing thereby realize moving back.And the moon/non-ionic surface active agent has poly-, the effects such as counnter attack is stained with, dispersion, chelating of very good anti-freezing, also can avoid all " oligomer " to be deposited on fabric and the dyeing machinery, and have stronger dispersion, level dyeing, remove the loose colour ability, can effectively improve cloth cover effect, coloured light and the COLOR FASTNESS of institute's dyeing and weaving thing in conjunction with other auxiliary agent.In the destarch process of fabric, though the anionic desizing agent can make slurry be dissolved in the water-bath, but inevitably there is the part slurry to come off naturally because of the motoricity of fabric, or the impurity of fabric face can't be dissolved in the water-bath, at this moment the moon/non-ionic surface active agent has just played poly-, the effects such as counnter attack is stained with, dispersion, chelating of a kind of anti-freezing, form one deck at fabric face and have only just transparent molecular film of dye molecule, avoid the attachment phenomenon once more of slurry and impurity, improve dyeing quality.
The present invention with anionic desizing agent and these two kinds of auxiliary agents of the moon/non-ionic surface active agent according to certain proportioning common application in the woven fabric dyeing and finishing technology, these two kinds of auxiliary agents dye bath pH value in the early stage are to be in the alkalescent state, but passing along with rising time of temperature, pH value reduces gradually, this characteristic that pH value presented of these two kinds of auxiliary agents, the even colouring of suitable DISPERSE DYES and ACID DYES, be difficult for producing the dyeing quality problem, can realize that one step of destarch, dyeing, post processing finishes, realizing promptly that woven fabric moves back dyes with bathing.Compare with existing destarch, dyeing two bath methods, of the present invention moving back dyed same bath process, and per ten thousand plaiting water consumptions and quantity of wastewater effluent all can reduce about 50%, and charges for disposing pollutants can be saved about 50%; Every cylinder cloth dyeing about 40-50% of shortened process time increases the about 80-90% of output under the equal equipment situation; Per ten thousand plaitings are saved coal and are about 30-40%; Per ten thousand plaiting save electricity are about 40-50%; Per ten thousand plaiting hand labor power costs reduce about 20%.
