The hotel towel brand factory teaches you what to do when bath towels turn yellow:
What should I do after bath towels turn yellow? The best way is to use color bleaching detergent, but use hot water (generally above 60℃). After washing, rinse with water. The automatic washing machine can use steam to cool water. Heat to reach this temperature. If the yellowing is serious, use a reducing agent to reduce treatment (temperature around 60℃, bath ratio of 1:20 water), and normal watering after 5 minutes.
When hotels and guesthouses hand over bath towels to the laundry factory, they should carefully examine whether the laundry factory is clean and whether the washing equipment is advanced. Try to choose those with large scale and advanced technology. With the triple guarantee of high-quality equipment, washing technology, and professional detergents, bath towels are more worry-free to wash.
1. The water used for washing bath towels is hard
One reason for the yellowing of bath towels is that the washing water is hard, and the unsoftened water will contain a lot of organic and inorganic salts. These ionic salts include calcium, magnesium, iron, zinc, and manganese ions. During the washing process, it will deposit on the fabric and even enter the fiber. As the number of washings increases, the amount of deposition will increase. As a result, the bath towels become gray and hard. If groundwater is used, the phenomenon will be more serious.
2. The bath towels are not rinsed cleanly when washing
1. The detergent quality is poor or the amount added is small
This is one of the main reasons. The use of poor detergent can not completely wash the clothes. If the dirt accumulates and the detergent remains, the clothes will turn yellow. Therefore, not only professional detergents are needed, but also laundry workers need to be proficient in the dosage, time, and temperature of detergent.
2. Incomplete rinsing
When washing with a fully automatic industrial washing machine, after washing, there is a rinsing program. If the amount of rinsing water is not enough or the rinsing time is too short, the rinsing will be incomplete and the dirt will be evenly attached to the On the washed fabric, it will also cause the fabric to turn yellow.
3. No dechlorination treatment after using chlorine bleach
Some textile mills use chlorine-containing bleaching agents for bleaching, but if the process of dechlorination is not carried out, the chlorine will remain on the fabric and cause the linen to turn yellow.
