Abstract
A neutral solution method for desizing the fabric by one step to remove the size and water-soluble PVA fibres includes such steps choosing the aqueous solution of alcohol as neutral solution, pouring ni a washer, heating to 85-98 deg.C, immersing the fabric in it while washing for 1-30 min, and washing with cold water.
Description
Affiliated field
The present invention relates to the desizing method of fabric, is a kind of fabric neutral solution one step destarch method.
Background technology
In textile industry, fabric desizing occupies very critical role in pretreatment procedure, the slurry of fabric mostly adopts natural slurry, sex change slurry, synthetic slurry and composition thereof, slurry is as moving back the permeance property that can directly not influence fabric only, chemical substances such as obstruction dyestuff contact with fiber, and dyeing quality is poor; Simultaneously, slurry is present in the fabric also can influence serviceability, so people pay attention to especially to destarch.Destarch method commonly used at present has alkali destarch, enzyme desizing, sour destarch or oxidation destarch method, its technology comprises following processing step: fabric pads in above hot solution, swelling, hot water wash, cold wash operation, these method technologies are loaded down with trivial details, pad, swelling and hot water wash time is long, generally more than 1.5 hours, inefficiency, thermal energy consumption height, and generation contains the waste water of chemical substances such as acid, alkali, contaminated environment in a large number.
Summary of the invention
The purpose of this invention is to provide a kind of fabric neutral solution one step destarch method, loaded down with trivial details to solve prior art processes, the destarch time is long, inefficiency, and the thermal energy consumption height, and generation contains chemical substance wastewater problems such as acid, alkali in a large number.
The object of the present invention is achieved like this: this destarch method comprises following processing step: neutral solution apolegamy, heating, textile impregnation are washed and are moved back, the cold wash operation, neutral solution adopts ethanol water, textile impregnation is washed and moved back is in heatable rinsing machine, and temperature is controlled at 85-98 ℃.
The neutral solution apolegamy: selecting concentration for use is the ethanol water of 0.3-50%.
The neutral solution apolegamy: select for use to add chelated dispersants in ethanol water, its proportioning is: ethanol water: chelated dispersants=100: 0.5-2.
Chelated dispersants adopts polyphosphate or acrylic compounds the metal ion in PVA and the water to be had the auxiliary agent of chelation.
The present invention compared with prior art has the following advantages: 1) widely applicable, neutral solution can not cause damage to any fiber, so any fabric all is suitable for; 2) adopt the ethanol water of heating as neutral solution, can rapid permeability in crack between fabric fibre and the fiber, and in this gap, flow, the slurry of fiber surface and water-solubility PVA fiber can directly dissolve removing, technology is simple, has reduced to pad and the swelling operation; The destarch time drops to 1-30 minute by original more than 1.5 hours, thermal energy consumption is low, high efficiency; 3) chemical substance such as anacidity, alkali waste water does not have destruction to environment; 4) solved the molten difficult problem of removing of water-soluble polyvinyl alcohol fibers (water-solubility PVA fiber), molten to the water-solubility PVA fiber in the products such as water-solubility PVA fabric nonwoven cloth that adopt in the BLENDED FABRIC of hair and water-solubility PVA fiber and the computer embroidery except that special efficacy is more arranged.
The specific embodiment
Embodiment one: neutral solution employing concentration is 0.3% ethanol water.
Technological process: neutral solution apolegamy → heating → textile impregnation is washed and is moved back → cold wash.
Specification:
1, neutral solution apolegamy is chosen or is prepared ethanol content and accounts for 0.3% ethanol water.
2, heating adopts heatable rinsing machine that neutral solution is heated to 90-98 ℃.
3, textile impregnation is washed and is moved back, and fabric is put into the neutral solution that heats, and dipping is washed and moved back temperature and be controlled at 90-98 ℃, time 20-30 minute.
4, cold wash is same as the prior art.
Embodiment two: neutral solution employing concentration is 50% ethanol water.
Technological process is with example one
Specification:
1, neutral solution apolegamy is chosen or is prepared ethanol content and accounts for 50% ethanol water.
2, heating is heated to 85-90 ℃ with neutral solution.
3, textile impregnation is washed and is moved back, and temperature is controlled at 85-90 ℃, time 1-5 minute.
All the other are with example one
Embodiment three: neutral solution employing concentration is 10% ethanol water.
Except that ethanol water concentration, add the thermal control temperature and time respective change all the other technological processes and operation with example one.
Embodiment four: neutral solution adopts and add chelated dispersants in ethanol water.
Technological process is with example one
Specification:
1, neutral solution apolegamy: according to ethanol water: the ratio preparation of chelated dispersants=100: 0.5-2.
2, with ethanol water change in concentration in the neutral solution, adding the thermal control temperature and washing the time of moving back has outside the respective change, and all the other are with example one.
Claims (4)
1, a kind of fabric neutral solution one step destarch method is characterized in that comprising following processing step: neutral solution apolegamy, heating, textile impregnation are washed and are moved back, the cold wash operation, neutral solution adopts ethanol water, textile impregnation is washed and is moved back in heatable rinsing machine, and temperature is controlled at 85-98 ℃.
2, fabric neutral solution one step destarch method according to claim 1, it is characterized in that: the neutral solution apolegamy, selecting concentration for use is the ethanol water of 0.3-50%.
3, fabric neutral solution one step destarch method according to claim 1 is characterized in that: the neutral solution apolegamy, to select for use in ethanol water, to add chelated dispersants, and its proportioning is: ethanol water: chelated dispersants=100: 0.5-2.
4, fabric neutral solution one step destarch method according to claim 3, it is characterized in that: chelated dispersants adopts polyphosphate or acrylic compounds the metal ion in PVA and the water to be had the auxiliary agent of chelation.
