Chemical disinfection of linen
Chemical disinfection is the use of chemical drugs to penetrate the body of bacteria, coagulate and denature bacterial proteins, interfere with the activity of bacterial enzymes, inhibit bacterial metabolism and growth, damage the structure of bacterial membranes, change their permeability, and destroy their physiological functions, so as to achieve disinfection and sterilization. the goal of. When the hotel washes temperature-sensitive fabrics, such as chemical fibers, wool, or uses low-temperature washing, chemical disinfection methods must be used to achieve linen disinfection.

Note: When chemical disinfection is used to wash linen, all wash standardization operations must be carried out in accordance with the disinfection specifications for the chemicals used.
NO.3
Linen light disinfection method
That is to use physical effects such as temperature to denature or solidify the proteins and enzymes of microorganisms to achieve the purpose of disinfection and sterilization. The light disinfection method mainly uses ultraviolet radiation to photolytically denature bacterial proteins and cause bacterial death.
1. Sun exposure disinfection method: Sun exposure method is used for disinfection of pillows, mattresses, mattresses, cotton wool, etc. Generally, the disinfection effect can be achieved by exposure to the sun for 6 hours, and it needs to be turned over every 2 hours during the period.
