1.Check the machine frequently to prevent secondary pollution and man-made damage. The loading amount should be appropriate (80%~85%) during washing. Too much or too little will affect the cleanliness and wear of the linen.
2.Before the washing operation, the machine should be empty to check whether there are sharp and iron impurities in the drum of the machine.
3.Use detergents correctly, master reasonable feeding time and temperature, and understand the basic characteristics and usage methods of detergents.
4.Avoid direct contact of cotton fabrics with strongly acidic or corrosive chemicals.
5.Do a good job of sorting before washing, including sorting of linen types and separation of sundries.
6.Care should be taken during the storage and transportation of linen to prevent secondary pollution and accidental tearing.
7.Do a good job in the classification of old and new linen. The natural damage and abnormal damage of old linen should be treated separately. The strength of old and new linen should be different. The length of dehydration time should also be different.
