1. 检查分类
1. Inspection classification
需要在洗涤前作分拣分类处理。
Firstly, sorting and classification processing needs to be carried out before washing.
按颜色分类：不同的布草处理可能会引起相互污染，而不同颜色的同类布草处理方法也不同。
Classification by color: Different fabric treatments may cause mutual pollution, and the same type of fabric treatment method with different colors also varies.
按布草污垢的类别分类：这种分类方法是针对布草在使用过程中所具有的特殊污垢，一般采用专用的去渍剂处理这些特殊污垢。重垢布草如果是与同类的一般污垢程度布草一起作常规处理，只会引起大量返洗的浪费。
Classification according to the category of cloth grass dirt: This classification method is aimed at the special dirt that cloth grass has during use, and generally uses specialized stain removers to treat these special dirt. If the heavy scale fabric is treated together with similar general scale fabric for routine treatment, it will only cause a large amount of waste in backwashing.
按布草质地分类：如纯棉床单、涤棉床单等必须分开处理，而地巾应特别分开，单独专机洗涤烘干
Classified according to the texture of the linen: pure cotton sheets, polyester cotton sheets, etc. must be treated separately, while floor towels should be specially separated and washed and dried separately with a dedicated machine
2.去渍处理
2. Stain removal treatment
应用一些化学药品并借助一些正确的机械作用去除常规水洗与干洗中无法去掉的污渍。
Apply some chemicals and use professional and correct mechanical actions to remove stains that cannot be removed during regular water and dry cleaning.
3.过水和预洗
3. Watering and pre washing
对于中、重污垢的洗涤一般要采用冲洗步骤。预洗是加入适量洗涤剂的一个预去污过程。针对特别严重的污垢，预洗则是必选的步骤。预洗一般可安排在冲洗步骤之后，也可以直接进入预洗过程
For washing medium and heavy dirt, a washing step is generally used. Pre washing is a pre cleaning process in which an appropriate amount of detergent is added. For particularly severe dirt, pre washing is a necessary step. Pre washing can generally be arranged after the washing step or directly enter the pre washing process
4.主洗
4. Main washing
在适当的洗液浓度、温度、足够的作用时间等因素的结合下，实现去污目的。
Under the combination of appropriate washing solution concentration, temperature, sufficient action time, and other factors, achieve the purpose of decontamination.
5.漂白
5. Bleaching
此过程是主洗去污的补充步骤，主要去除主洗步骤中不能完全去掉的色素类污垢。
This process is a supplementary step to the main washing and decontamination process, mainly removing pigmented dirt that cannot be completely removed during the main washing step.
6.漂洗
6. Rinsing
漂洗是一个扩散过程，用30℃～50℃的水温与高水位去除织物中残存含有污垢的洗液成分，从而达到清洗目的。
Rinsing is a diffusion process that uses a water temperature of 30 ℃ to 50 ℃ and a high water level to remove residual detergent components containing dirt from the fabric, thus achieving the cleaning purpose.
7.过水和脱水
7. Overflow and dehydration
利用洗衣机滚筒高速旋转时产生的离心力，使滚筒内织物含水量最大限度地减低。
Utilize the centrifugal force generated by the high-speed rotation of the washing machine drum to minimize the moisture content of the fabric inside the drum.
8.过酸中和
8. Neutralization by peracidity
洗涤中通常使用的洗涤剂呈碱性，虽然经过多次清洗，亦不能保证没有任何碱性成分存在。碱性物的存在对洗涤物的外观、手感都会造成一定影响，更甚者，则会对人体的皮肤和健康造成不利影响。而利用酸与碱发生中和反应，就可以解决这些问题。
The detergent commonly used in washing is alkaline, and although it has been cleaned multiple times, it cannot be guaranteed that there are no alkaline components present. The presence of alkaline substances can have a certain impact on the appearance and feel of washing products, and even worse, it can have adverse effects on human skin and health. By utilizing neutralization reactions between acids and bases, these problems can be solved.
9.柔软处理
9. Softening treatment
柔软处理能使织物手感舒适，同时能防止静电产生，并起到润滑作用。
Soft treatment can make the fabric feel comfortable, while preventing the generation of static electricity and providing lubrication.
10.上浆
10. Sizing
上浆步骤主要针对餐厅的台布、餐巾、某些制服等棉制品或混合纤维织物。上浆后能使被浆织物表面挺括，防止起毛，同时也在被浆织物表面结一层浆膜，对污垢渗透有一定的阻碍作用。
The sizing process mainly targets cotton products or mixed fiber fabrics such as tablecloths, napkins, and certain uniforms in restaurants. After sizing, it can make the surface of the fabric straightened and prevent fuzzing. At the same time, it also forms a layer of slurry film on the surface of the fabric, which has a certain obstruction effect on dirt penetration.
