After a period of use, newly bought towels will turn yellow or black like the light-colored clothes we usually wear, which is very ugly.This article will share with you the reasons why pure cotton hotel linens turn yellow and how to deal with them.
The main reasons why newly purchased towels turn yellow are as follows:
Part A: The Washing Water Is Hard
One reason why linen turns yellow is that the washing water is hard. Unsoftened water will contain a large amount of organic salts and inorganic salts. These are present in the water in an ionic state, including calcium, magnesium, iron, zinc, and manganese ions. During the washing process, it will be deposited on the fabric and even enter the fiber.As the number of washes increases, the amount of sedimentation will increase.
Part B:Using Inferior Detergent Or Do Not Rinse Cleanly
l The Detergent Is Inferior Or The Amount Of Detergent Added Is Small
This reason is one of the main reasons. The use of inferior detergent cannot completely clean the clothes. In the long run, the accumulation of dirt and the residue of detergent will cause the clothes to turn yellow.Therefore, not only professional detergents are needed, but laundry workers also need to be proficient in the amount, time and temperature of detergents.
l Rinsing Incompletely
When using a fully automatic industrial washing machine, there is a rinsing process after washing. If the amount of rinsing water is not enough, or the rinsing time is too short, the rinsing will be incomplete and the washed dirt will evenly adhere to the surface. On the fabric being washed, it will also cause the fabric to turn yellow.
l No Dechlorination After Using Chlorine Bleach
Some textile factories will use chlorine-containing bleach for bleaching, but if the dechlorination process is not carried out, chlorine will remain on the fabric, causing the linen to turn yellow.
Part C:The Way After Linens Turn Yellow
What to do when hotel linens turn yellow? The best way is to use color bleaching washing powder, but you need to use hot water (generally above 60°C). Fully automatic washer-extractors can reach this temperature by heating cold water with steam.If the yellowing is severe, use a reducing agent for reduction treatment (temperature around 60°C, liquor ratio 1:20 water), and add water normally after 5 minutes.If the yellowing is severe, use a reducing agent for reduction treatment (temperature around 60°C, liquor ratio 1:20 water), and add water normally after 5 minutes.
