In recent years, with the worldwide rapid development of the hotel service industry, commercial laundry has also sprung up. Although as the same form of fabric washing, commercial laundry has completely different chemicals and washing procedures than domestic laundry.
The commercial laundry room has a large washing volume (the daily washing volume of a single store ranges from several tons to dozens of tons) and a single washing object (mainly white linens such as bed sheets, quilt covers, pillowcases, towels, etc.), which provides convenience for standardized washing.
Commercial laundry not only has high requirements on washing efficiency, but also has extremely high requirements on the cleaning rate of fabrics, the maintenance of whiteness and brightness, and the softness of towels. In this context, commercial laundry usually chooses professional washing chemicals and standard washing procedures, and strictly controls other washing factors (such as water quality, temperature, mechanical force, etc.) to ensure the quality of washing.
Liquid washing chemicals have developed rapidly in the past ten years. In addition to the reasons mentioned above, the prohibition of sodium tripolyphosphate is also one of the reasons for its rapid development. The advantage of the liquefied material is that the dispenser can be used to realize automatic feeding, reduce manual participation, and ensure the stability of washing quality.
The liquefied materials mainly include main lotion, emulsifier, alkaline auxiliary, neutralizing acid agent, softener, oxygen bleaching agent, chlorine bleaching agent. The synergistic use of different chemicals can significantly improve the decontamination effect. In addition to a wide variety of washing chemicals, commercial laundry also has strict requirements for the control of washing processes and various factors.
Usually a set of linen washing process is divided into pre-wash, main wash, bleaching, rinsing, middle stripping, neutralization, softening, high strippin, drying. Some linens need to be cleaned separately with stain treatment, backwashing, etc. In the whole laundry work, it also involves the transportation, sorting and other work of linen.
Therefore, there are too many factors that affect the quality of linen washing. In the process of linen washing, the selection and addition of washing chemicals, water quality, washing temperature, washing time, washing water level, washing process, stain removal, linen transportation, separation improper handling of a certain factor in the process of sorting and transportation will cause washing accidents. For example, accidents such as low cleaning rate, graying and yellowing of linen, and shortening of life due to damage to linen.
The occurrence of linen washing accidents often brings great losses to the laundry. Due to its own characteristics, the linen washing in commercial laundry requires staff to have a correct concept and understand basic washing knowledge. In actual operation, it is also necessary to strictly carry out standardized operations, so as to effectively avoid the occurrence of washing accidents.
