Clothing people must know the washing process of jeans.

1, laundry washing

Ordinary washing is ordinary washing, but we changed the familiar washing into mechanization.

General washing can be divided into light general washing, general washing and heavy general washing. Usually, it takes about 5 minutes for light washing, 15 minutes for light washing and 30 minutes for heavy washing. This time is not accurate, and there is no obvious boundary between the three washing methods.

2. Enzymatic washing

Enzyme is a kind of cellulase. At a certain PH value and temperature, it can degrade the fiber structure, make the cloth surface gently fade and lose hair (produce "peach skin velvet effect"), and get a lasting soft effect. Stone can be used or replaced by stone. If it is used with stone, it is usually called enzyme stone mill.

3. Stone washing/stone washing

Stone washing is to add a certain size of pumice to the washing water to polish the pumice and clothes. The water level in the polishing tank is at a low level where the clothes are completely soaked, so that the pumice can contact the clothes well.

Generally, washing or rinsing can be performed before the stone mill, and rinsing can also be performed after the stone mill. According to different requirements of customers, Yellowstone, Baishi, AAA stone, artificial stone and rubber ball can be selected for washing to achieve different washing effects. After washing, the cloth is gray and old, and the clothes are slightly to severely damaged.

Step 4 wash sand

Sand washing is to use some alkaline and oxidizing additives to make clothes have a certain fading effect and old feeling after washing. If it is matched with a stone mill, the surface of the washed cloth will produce a layer of soft fluff like frost, and some softener will be added to make the washed cloth soft, thus improving the comfort of wearing.

5. CHEMICAL WASH

Chemical washing mainly achieves the purpose of fading by using strong alkali additives (NaOHNaSi03, etc.). ). After washing clothes, there is an obvious sense of obsolescence, and then adding softener, the clothes will have a soft and plump effect. If stone is added to chemical washing, it is called fossil washing, which can enhance the effect of chemical stone washing and make clothes have a strong sense of shabby. Fossil washing combines the effects of chemical washing and stone washing, and can achieve the effect of imitating old pilling after washing.
