Why does the towel turn yellow?

Dehydration is not a problem: If the towel is not dehydrated during washing, it will form a residue of alkaline chemicals, which will remain in the towel fiber, causing the towel to be hard and the towel to be weak.

3. Residues of chlorine bleaching
Chlorine bleaching agent is a strong bleaching agent in washing chemicals, which is somewhat damaged by cotton fibers in cotton fabrics. It must be used and controlled reasonably during the washing. If the temperature washing time concentration control is relatively safe, on the contrary, the temperature, concentration, quantity control is not good, coupled with dehydration is not clean, so that the residual material formed in the cotton fiber, the residual material is harmful to the fiber of the cotton fabric. The result is that the towel fabric is yellow and hard.
