Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly makes fabric have the cotton-containing fabrics that makes that non-ironing function and surface have durable gloss to have the processing method of durable gloss.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of processing method that makes cotton-containing fabrics have durable gloss, and it increases following concrete technology step after weaving the grey cloth process traditional singing → destarch → mercerization that obtains:
(1), get reaction resin 50~100g/L, catalyst 10~20g/L, optical brightener 20~60g/L, strong protecting agent 20~30g/L are uniformly mixed into RESIN FINISH liquid, and the pH value of control RESIN FINISH liquid is between 4.5~5.5;
(2), RESIN FINISH liquid is put in the hopper of setting machine, then grey cloth is padded by setting machine and dry, the liquid carrying rate of control grey cloth is 60%~70%, and containing the tide value is 6%~10%;
(3) but, the grey cloth after will padding carries out calendering by Nip L three rolling ray machines;
(4), the grey cloth after the calendering is baked.
Reaction resin described in the step (1) is the modification hydroxymethyl-2 dihydroxy-ethylene urea, and described optical brightener is the glazing smooth agent.
The specific embodiment of described step (3) is: but first the steel rider of Nip L three rolling ray machines is heated up, but when heating up, keep steel rider to contact all the time and relatively rotate with Nip's roller with nylon jacket, when being warmed up to 120 ℃~170 ℃, keep 20~40min, but then to applying the pressure of 0~250N/mm between steel rider and the Nip's roller with nylon jacket, but to the pressure that applies 0~250N/mm between Nip's roller of nylon jacket and the cotton roller, and but the speed of a motor vehicle of setting Nip L three rolling ray machines is 20~30m/min, but the grey cloth after will padding at last is by carrying out calendering between steel rider and the Nip's roller with nylon jacket.
In the described step (3), the grey cloth after the calendering is cooled off, when preventing that temperature is higher, the severe and brute force of damage fabric of the resin crosslinks in the grey cloth.
In the described baking, setting baking temperature is 140 ℃~160 ℃, and the time of baking is 1~5min.
After step (4), increase the preshrinking process to grey cloth.
After mercerization, before the preparation RESIN FINISH liquid, increase the liquefied ammonia of grey cloth or at least one operation in the washing process.
Cotton-containing fabrics refers to cotton, fiber crops, cotton/wash BLENDED FABRIC, cotton/flax blended fabric etc. among the present invention.
But Nip L three rolling ray machines are commercially available ready-made equipment.
Compared with prior art, advantage of the present invention is to have the outward appearance of bright luster by the cotton-containing fabrics that this method processing obtains, and after the grey cloth calendering, grey cloth is baked and preshrunk, make fiber and resin generation cross-linking reaction in the grey cloth, easily scald even non-ironing grade thereby fabric is reached, the fabric smooth appearance after guaranteeing to wash can not affect its surperficial gloss, can make on the other hand optical brightener anchor at more enduringly fiber surface with inner, reach washable purpose; And but employing Nip L three rolling ray machines carry out calendering to grey cloth, because nylon jacket has the advantages such as high strength, high elasticity, high initial hardness, can make the fabric after the calendering become soft and the sense of hanging down is arranged, avoid traditional calender to bring fabric stiff and old-fashioned and inflexible feel.
The specific embodiment
