The invention relates to the technical field of dyeing and especially relates to the one-bath-process dyeing for PPT chinlon mucilage glue. The dyeing method comprises the following steps: pretreatment: adding PPT chinlon mucilage glue and water into a dye vat, adding a degreasing agent, rising temperature to 90 DEG C, keeping temperature for 10min and cleaning; dyeing: rising temperature to 30 DEG C, adding auxiliaries, adding dyestuff and anhydrous sodium sulphate after 10min, rising temperature to 40 DEG C at the speed of 1 DEG C / min, keeping temperature for 10min, and then rising temperature to 98 DEG C at the speed of 0.5 DEG C / min, keeping temperature for 30-60min and reducing temperature to 80 DEG C; adding sodium carbonate, keeping temperature for 30-60min and cleaning; adding glacial acetic acid and soaping agent, quickly rising temperature to 80 DEG C, keeping temperature for 10min and cleaning; adding a softening agent, rising temperature to 40 DEG C, keeping temperature for 20min and then taking out of the vat. The one-bath-process dyeing for PPT chinlon mucilage glue according to the invention can effectively increase color fastness and prevent dyeing defects.
Description
Technical field [0001] The invention relates to the technical field of dyeing, in particular to one-bath dyeing of PPT nylon viscose. Background technique [0002] The existing PPT nylon viscose has poor color fastness after dyeing, and it is easy to produce stains. At the same time, two baths are currently used, causing serious water consumption. Summary of the invention [0003] The purpose of the present invention is to provide a one-bath dyeing of PPT nylon viscose which is simple in process, can effectively improve the color fastness, and avoids the generation of colored flowers in order to solve the above-mentioned technical deficiencies. [0004] In order to achieve the above purpose, a one-bath dyeing of PPT nylon viscose designed by the present invention, pre-treatment: add PPT nylon viscose and water into the dyeing vat, add degreasing agent, heat up to 90°C, keep warm for 10 minutes, and clean. ; Dyeing: increase the temperature to 30°C, add the auxiliary agent, add dye...
