Water standards and common issues for hotel industrial washing machines

There is another factor in the cleanliness of hotel industrial washing machines that cannot be fundamentally changed, and that is water quality.
The use of hotel industrial washing machines requires water quality testing and softening. Water is an important indicator for washing linen in hotel industrial washing machines, and is necessary for a series of processes such as rinsing, pre washing, main washing, and bleaching. Good water quality is one of the highest standards for ensuring washing quality.

The water required for hotel industrial washing machines is soft water, but in many hard water areas, the water used for hotel industrial washing machines has become the reason why many linens cannot be washed. How to identify the performance of temporary hard water and permanent hard water in hard water? Just pour an appropriate amount of water sample into a beaker, heat and boil it, let it stand for a few minutes, and observe carefully. If sediment is found in the water, it is determined that the water sample is temporarily hard water; If there is no precipitation, take out the water sample and pour it into the test tube. Add a small amount of prepared transparent soap solution and gently shake it while adding. If the water sample becomes turbid and the foam generated after shaking disappears rapidly, it can be determined that the water sample is permanent hard water.
We all know that the linens in hotels need to be as shiny as new, and yellowed linens give people an unclean feeling. Why is it that many hotel industrial washing machine operators use the correct techniques, but still cannot avoid the phenomenon of yellowing of linen?
The yellowing of linen may be due to several reasons, one of which is due to water quality issues. The water has not been softened and rust has appeared, causing the linen to turn yellow; Or it may be due to the high temperature during drying, causing the linen to turn yellow; Chlorine bleaching itself causes the fabric to turn yellow. If there is no whitening or if the water is not clear, over time, yellowing of the fabric can also occur.
In fact, there will be many problems encountered during the process of washing linen. As long as the operator of the hotel industrial washing machine can adopt the correct washing methods and classify, dirty, and separate the linen during washing, many problems will be easily solved.
