Solve the reason why the cloth becomes yellow:

▼

One reason for the yellowing is that the water quality of the washing is hard. Unsoftened water will contain a large amount of organic and inorganic salts. These salts in the ionic state include calcium, magnesium, iron, zinc and manganese ions, which will deposit on the fabric during the washing process and may even enter the fiber interior. .

As the number of washings increases, the amount of deposition will increase. As a result, the cloth, especially the towel cloth, is grayed and hardened. If washed with ground water, the phenomenon will be more serious.

Uncleaning is one of the main reasons. The use of poor detergent does not completely wash the linen. In the long run, the accumulation of dirt, the residue of the detergent, and the linen will turn yellow.

Therefore, not only professional detergents are required, but also laundry workers are required to master the amount, time and temperature of detergents.

When washing with a fully automatic industrial washing machine, after washing, there are three rinsing procedures. If the amount of rinsing is insufficient, or the rinsing time is too short, the rinsing is not thorough, and the washed dirt is evenly attached to the washing. On the fabric, it also causes the fabric to turn yellow.
