Jacquard Logo Towel Set Hotel 100% Cotton Bathroom Bath Hand Face Towel

reason:

Dehydration problem: If the towel is not dehydrated thoroughly during washing, it will form residues of alkaline chemicals that remain in the towel fibers, causing the towel to harden and reducing its firmness.

Alkaline chemicals are safe for cotton fibers during the washing process and will not damage towel fibers. But if the dehydration is not thorough, the residue of alkaline detergent will remain in the towel fibers, and drying the towel will make it hard and reduce its softness.

The residue of ammonia bleaching is a strong bleaching agent in detergent products, which can cause some damage to cotton fibers in cotton fabrics. It is necessary to use and control it reasonably during washing. If the temperature, washing time, and concentration are well controlled, it is relatively safe. On the contrary, if the temperature, concentration, and quantity are not well controlled, coupled with incomplete dehydration, residual substances will form in cotton fibers, which can damage the fibers of cotton fabrics. Causing yellowing and hardening of towel fabrics.

Standardized operation of washing towels can reduce yellowing

The use of raw materials should be reasonable and appropriate, and the operation procedure should be followed: the last step of towel washing is to use acid to neutralize. If the acid is not neutralized properly, it can cause the fabric to turn yellow and gray. During the washing process, due to factors such as high water hardness and poor water quality, towels are prone to graying and yellowing. These phenomena often occur when using acid to neutralize and restore the whiteness of towels. When using, it should be noted that cotton fibers are not afraid of acid or alkali. If acid is frequently used for washing, the lifespan of towels can be significantly reduced. Therefore, the dosage should be controlled. The pH adjustment agent for cotton fabrics should be adjusted to 5.5-65, and the pH value of our human skin is basically the same.

terms of settlement:

You can put the towel into the pot and submerge it with water to make it straight. Then sprinkle a handful of alkaline noodles and boil for 5 minutes. Rinse with hot water
