The hotel towel supplier analyzed the yellowing of hotel towels for several reasons:
The water quality of washing hotel towels is hard
One reason for the yellowing of hotel towels is that the water quality of the washing is hard. The unsoftened water will contain a large amount of organic and inorganic salts. The salts in the ionic state include calcium, magnesium, iron, zinc and manganese ions. During the washing process, it will deposit on the fabric and even enter the inside of the fiber. As the number of washings increases, the amount of deposition will increase. As a result, the hotel towel is grayed and hardened. If groundwater is used, the phenomenon will be more serious.
Washing the hotel towels when the rinse is not clean
1. Poor detergent quality or less added
This reason is one of the main reasons. The use of poor detergent does not completely wash the clothes. In the long run, the accumulation of dirt, the residue of the detergent, the clothes will turn yellow. Therefore, not only professional detergents are required, but also laundry workers need to be proficient in the amount, time and temperature of detergents.
2. Rinsing is not thorough
When washing with a fully automatic industrial washing machine, after washing, there is a rinsing procedure. If the amount of rinsing water is not enough, or the rinsing time is too short, the rinsing is not thorough, and the washed dirt is evenly attached. On the washed fabric, it also causes the fabric to turn yellow.
3. Dechlorination treatment is not carried out after using chlorine bleach
Some textile mills use bleach with chlorine-containing bleach, but if there is no dechlorination process, the chlorine will remain on the fabric, causing yellowing of the linen.
