Chinlon/the CDP fabrics/dacron one-bath process method

The invention discloses a kind of chinlon/the CDP fabrics/dacron one-bath process method, have steps of: 1. fabric is immersed in pretreatment liquid and processes 20min～60min, then carry out pickling；2. the fabric after pre-treatment is immersed in containing washing in the dye liquor with brightening agent, the dye of positive ion and acid stain, at a temperature of 110 DEG C～130 DEG C, carries out 30min～60min that dye, be then cooled to less than 60 DEG C discharge opeings；3. the fabric after dyeing is first carried out room temperature water to wash, after discharge opeing, then carry out acid fixation.The method of the present invention is by selecting suitably to wash with brightening agent, the dye of positive ion and acid stain, it is thus possible to realize the one-bath process of chinlon/the CDP fabrics/dacron, the flaws such as the colourless flower of fabric after dyeing, mottle, Washing and colorfastness to rubbing are the highest, quality is preferable, and shorten dyeing flow process, decrease the damage to fiber, thus reduce energy consumption.
