2021-03-18

The desizing, scouring, bleaching and mercerizing of the fabrics are all important processes before the printing and dyeing of the printing and dyeing auxiliaries. 

The printing and dyeing auxiliaries can improve the permeability of the lye, promote the emulsification of waxes, and further remove the impurities from the fiber Dispersed in the scouring liquid, the printing and dyeing auxiliary is a polymer film-forming substance that adheres the coating to the fabric through film formation. 

Therefore, the adhesive is required to have trained adhesion to the fabric and reproducibility, aging resistance, Solvent resistance, acid and alkali resistance, chemical resistance, clear and transparent film formation, does not change color after printing, does not damage the fiber, has certain flexibility, good hand feel, and is easy to remove from the printing machine.
