Watermarking refers to the dripping or splashing of water droplets on the dyed semi-product before dyeing, dyeing fixing process and dyeing after dyeing, resulting in the dilution and destruction of the dye and chemical additives on the fabric of the dripping, causing local light color, and even white in serious cases, or the dye color of the dyed fabric is not destroyed, but due to the reason of containing water droplets, resulting in watermark stains on the fabric.

cause

The dyeing and finishing process is characterized by more water, more steam and more condensate

1Water dripping from factory roof

2The water vapor evaporating from the drying machine, the cover shell of the pre-drying machine and the frame condenses into water droplets when drying

3The transversal water pipe closure door on the drying machine is not tightly closed, resulting in water leakage

4Steam leakage, water leakage or sand holes in the drying cylinder at both ends of the steam inlet and outlet

5Upper steam splint is not open

Overcoming method

1, before mercerizing water droplets can be eliminated by mercerizing, fabric mercerizing and dyeing process and not complete color fixation should avoid water droplets, after finishing water droplets affect the appearance, but can be eliminated.

2, factory design should pay attention to anti-fog, waterproof drop generation;

3, strengthen the management of cloth;

4. Prevent water leakage and steam leakage.
