Abstract
The invention provides a washable and wearable postcure cotton elastic fabric, and relates to the multifunction afterfinishing process of cotton elastic fabrics, which comprises the steps of dye and afterfinishing as follows: adding migration inhibitor in the staining solution in the process of dye; after the dye, adopting infrared ray for prebaking, dying at a low temperature and color fixing, wherein the drying temperature is 60-70 DEG C and the wind speed is 50-60%; during the afterfinishing, the finishing agent is prepared from a penetrant JFC, resin Permafresh EFR-6C, epoxy group modified silicon softening agent Advaansoft AV-920, polyurethane BAYPRET NANO-PU and acrylic ester adhesive ACRYGEN61192 by compatibility, wherein the washability (ColorBand) of the obtained product can achieve grade 3.5 changing in color (AATCC135)after washing for 30 times with water; the abrasive resistance can be 15000 rotation (BS EN ISO 12947 part 2, Martindale), the planeness (crease resistance) can be grade of 3.5 (AATCC 124) after washing with water for 30 times, seams of a trouser leg can be grade of 4.0 (AATCC 88)after washing with water for 30 times.
Description
Technical field
The present invention relates to cotton stockinette function finishing technology, refer in particular to a kind of postcure cotton elastic fabric finishing process of washable and wearable.
Background technology
Existing textile dyeing is done with infrared preliminary drying earlier after pad dyeing, gets into (100-120 ℃ of drying room oven dry fixation again; Wind speed 100%), temperature is high during oven dry, and wind speed is fast; Be a kind of mode of rapid dyeing, core is not passed through in the painting cloth dyeing of gained, and is not washable; Generally wash 3-5 time and will go out whiting (not washable), can not satisfy present washable requirement.
Fabric after the dyeing will reach characteristics such as non-ironing, crease-resistant, must carry out the back arrangement, the method that fabric carries out the back arrangement be with fabric on stenter with dippings such as bleeding agent, resin, fiber protective agent, silicone oil softener, oven dry, preshrunk processing again.Cure after this in the finishing technique to adopt usually and add the resin method, can cause fabric strength impaired but add resin, its brute force will reduce 40-50%.And for stockinette; Owing to be coated with spandex in the yarn; More general non-elastic force cloth brute force will reduce 20-30%, if bake finishing technique after letting elastic force cloth adopt, it is powerful impaired even more serious; According to baking the cotton elastic fabric brute force behind the usual way is to meet the demands, and fabric is very not wear-resisting.The resultant cotton elastic fabric of this kind afterfinish method, resin demand is big, and is big to fibre damage, thereby influences ABRASION RESISTANCE, and abrasion test has only 5000-6000 to change, and can not satisfy present high abrasion requirement.
For above-mentioned reasons, lining is repeatedly washed the back generation and faded, and is washable inadequately, washes 30 times, and flatness, the seams of a trouser leg do not reach 3 grades, and ready-made clothes seam and flanging wear phenomenon are serious, cause the consumer often to complain.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of postcure cotton elastic fabric finishing process of washable and wearable is provided, and institute's product flatness that obtains is high, and the washable and wearable performance is good.
The object of the invention realizes that main the improvement is in dyeing liquor, to increase migration inhibitor (20-30g/l), when oven dry, adopts low temperature to dry (60-70 ℃ at a slow speed; Wind speed 50-60%); Reduce dyestuff moving when oven dry, thereby improve the through-dyeing of dyeing, strengthen wear-resisting fastness to washing; Secondly, in the finishing agent of back arrangement, add polyurethane and polypropylene binders, reduce resin demand, and make auxiliary agent be attached to yam surface, thereby improve ABRASION RESISTANCE and wrinkle resistance.
Specifically, the postcure cotton elastic fabric finishing process of washable and wearable comprises dyeing and back arrangement, and adding in the dyeing liquor when it is characterized in that dyeing has migration inhibitor; Dyeing back adopts infrared preliminary drying to do, low temperature drying fixation again, and bake out temperature is 60-70 ℃, wind speed 50-60%; In the arrangement of back, each component formula of finishing agent is:
Penetrating agent JFC 5-10g/L
Resin Permafresh EFR-6C 240-250g/L epoxy radicals modification silicone softener Advaansoft AV-920 60-70g/L
Polyurethane BAYPRET NANO-PU 100-120g/L
Acrylate adhesive ACRYGEN 61192 50-60g/L.
The migration inhibitor that adds in this technology dyeing liquor is generally the acrylic compounds migration inhibitor, and addition is 20-30g/l, and main effect is to prevent dye migration, makes its imbue core, improves washing fastness, anti-fading; The acrylic compounds migration inhibitor concentration that adds in this technology is higher, and one times that is the migration inhibitor conventional amount used more than the amount.
The dyeing liquor of this technology also increases has salt (sodium chloride) to improve the infiltration colour fixation of dyestuff, and the addition of salt is 20-30g/L.
During oven dry, drying room temperature and air quantity are set lower, are to let cloth slowly dry, and prevent dye migration, and the inside and outside aberration of yarn is reduced, and improve washability.
In the dressing liquid prescription that the back arrangement is adopted, epoxy radicals modification silicone softener Advaansoft AV-920 can make the back good hand touch; Adding has BAYPRET NANO-PU (polyurethane) and ACRYGEN 61192 (acrylate adhesive); Through reducing resin demand (reducing 20-30%) in the dressing liquid of former back; BAYPRET NANO-PU (polyurethane) and ACRYGEN61192 (acrylate adhesive) form film and are attached to the lining surface; Improve ABRASION RESISTANCE, increased flatness.Used BAYPRET NANO-PU (polyurethane) is that nanoscale disperses, the high-end finishing agent of self-crosslinking polyethers polyurethane type; The nanoscale emulsion has best dispersion and permeance property; Can between fiber surface and fiber, form a skim, can reduce powerful loss, increase ABRASION RESISTANCE.Used ACRYGEN 61192 (acrylate adhesive) is an acrylic polymer, increases fabric abrasion resistance.
For reducing formaldehyde in the fabric, be added with the urea of 4-8g/L in the dressing liquid.
Through this finishing technique, it is 3.5 grades (AATCC135) that the product washability (ColorBand) of acquisition reaches 30 washing variable colors; ABRASION RESISTANCE 15000 changes that (BS EN ISO 12947 part 2 Martindale), reach 3.5 grades (AATCC 124) after flatness (crease-resistant degree) washing 30 times, reach 4.0 grades (AATCC 88) after the seams of a trouser leg washing 30 times, are a kind ofly to bake technology after senior.
