Why does the hotel linen turn yellow?

There are several reasons for the yellowing of the linen:

1. The water is harder.

One reason for the yellowing is that the water is hard, and that raw water contains lots of organic salts and dietary mineral, including calcium, magnesium, iron, zinc, and manganese. In the process of washing, they build up on the fabric, even into the fibers. As the number of water washes increases, there will be more and more sediment. That causes the linen gray and harden, especially the towel. If you use groundwater, it's going to get worse.

2. Problems of washing and rinsing.

• Poor quality of detergent or less.

This is one of the main reasons. Using bad detergents does not fully wash the cloth, and long-term, the accumulation of dirt, the residue of the detergent, and the grass will turn yellow. So not only do they need professional detergents, they also need to be proficient in the amount, time and temperature of the detergent.

• Rinsing is not enough.

When using automatic industrial washing machine washing, after washing, there is a process of rinse, if there isn't enough water to wash it, or if it is too short to wash it, it will not be thoroughly washed. The stain that is washed and evenly placed on the washing fabric can also cause the fabric to turn yellow.

3. No dechlorination after the use of chlorine bleach

Some textile plants use chlorine bleach to bleach them, but if they don't perform the dechlorination process, the chlorine will be left on the fabric and it will be yellowing of the cloth.

What do we do when the linen turns yellow?

What do we do when the linen turns yellow? The best way to do this is to use a professional cleanser, but with a hot water requirement that requires more than 60 ℃, the washing will be ended with a rinse, which can be heated to the temperature by using steam to heat the cold water if the fully-automatic offline washing is used. If the yellow is serious, it can be treated with a reducer, which is treated at about 60 ℃ or so, and the ratio of 1：20, and then it is rinsed in 5 minutes.
