Revelation - clothing washing technology Music in Japan

In the late seventy s, China began to clothing dyeing was originally jeans atone, rinse and take revenge. Sand washing the rise in the eighty s silk garments, cotton and T/C clothing washed ( Shrink) Soft, washing, sand washing, and a small amount of garment dyeing, printing and dye. In the ninety s, the rise of enzyme treatment technology, is widely used to wash jeans, cotton clothing super soft polishing, knitwear.

in the last few years and the rise of permanent press resin finishing technology, for the dip of clothing, size and shape stability fabric processing method has improved greatly than ever before. Wash water industry along with the development of the clothing industry development, after many upscale clothing without clothing dyeing and finishing, has become a modernization of the clothing grade and added value of new technology.


spinning, dyeing and finishing, garment textile process after processing is typically after washing water treatment, in order to achieve decontamination, preshrunk, and soft, wool, or some special visual effect, make the comprehensive performance of the garment is closer to the norm, the color is more natural.





for China's current wash water sector, according to the purpose of washing water can be roughly divided into the following several types of wash water:


wash shrinkage


the fabric shrinkage exceed bid, before garment wash a piece of cloth, latitude and longitude measured to shrinkage, converted to garment size, and then according to the proportion. Make samples again after washing test, and make the garment shrinkage up to the standard. This kind of ready-made clothing, after washing. And the size of the shrink after must be in agreement with the test sample. This requires [ Washing shrinkage] Also should have a unified process.


wash shrinkage process: put clothes in 40 ℃ warm water in the pool, soak for half an hour ( Midway from time to time with the stick pressure the pressure, make all wetted) , remove the dehydration and drying.


wash shrinkage requirement: after washing, garment shrinkage 3% ( Note: according to different customer requirements and standards. ) 。


wash soft


soft clothing most requirements. Should the customer request, add softener of clothes washing shrinkage feel is adjusted.


put clothes in 40 ℃ warm water, add 2 grams/liter softener pool, washing, dehydration, drying.


wash soft requirements: after washing, clothes washing shrinkage fall, feel slightly soft. Wash the soft general arrangement at the end of the wash water or wash water and other steps under stric simultaneously.


wash cleaning


exported to some countries of the products, to guarantee formaldehyde-free or low formaldehyde. Now is widely used in dyeing and finishing industry resin anti-creasing preshrunk finishing processing technology, some fabric formaldehyde, formaldehyde taste will send out in space, make originally formaldehyde-free clothes smoked with a small amount of formaldehyde. If do not pay attention to, easy to cause a default.


wash cleaning process: 40 - 50 ℃ soaping ( Washing powder 1 g/l, soda ash 2 g/l) , washed, dehydration and drying.


wash cleaning requirements: cloth, no peculiar smell, formaldehyde-free.


unhairing


cotton yarn spinning, dyeing and clothing of multi-channel production process to evolve into clothes, are in the process of all kinds of cloth through all sorts of friction, cloth cover hairiness is outstanding not neat, affect the look and feel. In order to improve its appearance or improve the pilling resistance ( Pillingresistance) And common processing method is after enzyme washing processing, achieve to MAO.


unhairing process: enzyme washing ( Acidic conditions, 1 - 2g/L) , washed, dehydration and drying.


unhairing requirements: cloth cover hairiness is flat and level. Strong, the color standard.


wash and wear, Blank)


cotton fabric clothing, such as only after general wash water treatment, in the process of wearing apparel has wrinkled easily, affect the appearance. At present more popular solution is to join in the process of wet processing of resin, to wash and wear finishing. Wash and wear finishing processing can finalize the design in the fabric or garment washing process respectively. Depending on the type of resin, and its processing process also varies.


wash and wear process: resin about 60 g/L add catalyst washing ( Note: according to the requirement is different) , dehydration, Keep a certain moisture content) , very hot, dry.


wash and wear requirements: smooth, not easy corrugate, strength, color standard.


the cowboy washing


application of cellulase in denim class atone organizing principle is to use the cellulose enzyme hydrolysis of cellulose, such making that stay in the amorphous cellulose bromide indigo orchid also will fall off, such making that the surface effect of denim and stone mill. Is the difference between stone mill is kao mechanical wear fine male, and enzymatic mainly rely on biological catalytic hydrolysis of fiber.


the cowboy washing process: enzyme washing ( Or add stone) , washed, dried.


the cowboy washing requirements: reduce the cloth feather, a stone mill effect ( Fade, flowers) , back to dye.


comprehensive washing


the above several kinds of wash water method, multiple water ( At the same time) can be selected according to actual effect, 。
