▎ 摘 要
NOVELTY - Printing and dyeing graphene polyurethane fabric involves performing pre-treatment working fluid for cold reactor, adding 15-25g/L caustic soda, 4-6g/L hydrogen peroxide, 7-9g/L refining agent TF125L, 1.5-2.5g/L chelating agent TF-510T. The fabric is pad-rolled with roll-reduction ratio of 80-90%, then rolled, and then covered with plastic, sealed and stacked for 10-15 hours at a temperature of 40 degrees C, flat drum vibration water washing and shaking water washing working fluid, use 9-11g/L caustic soda, 3-5g/L refining agent TF125L. The fabric is pad-rolled. The pad is washed with shock, washed dry, and then subjected to secondary impregnation, washed with shock water, get off the wet fabric, and then rolled with plastic paper, air-cylinder pre-shrinking and pre-shrinking working fluid by using 4-6g/L caustic soda, 0.6-1.2g/L refining agent. USE - Method for printing and dyeing graphene polyurethane fabric. ADVANTAGE - The method enables to print and dye graphene polyurethane fabric that has has high color fastness. DETAILED DESCRIPTION - Printing and dyeing graphene polyurethane fabric involves performing pre-treatment working fluid for cold reactor, adding 15-25g/L caustic soda, 4-6g/L hydrogen peroxide, 7-9g/L refining agent TF125L, 1.5-2.5g/L chelating agent TF-510T. The fabric is pad-rolled with roll-reduction ratio of 80-90%, then rolled, and then covered with plastic, sealed and stacked for 10-15 hours at a temperature of 40 degrees C, flat drum vibration water washing and shaking water washing working fluid, use 9-11g/L caustic soda, 3-5g/L refining agent TF125L. The fabric is pad-rolled. The pad is washed with shock, washed dry, and then subjected to secondary impregnation, washed with shock water, get off the wet fabric, and then rolled with plastic paper, air-cylinder pre-shrinking and pre-shrinking working fluid by using 4-6g/L caustic soda, 0.6-1.2g/L refining agent. The fabric is immersed in the pre-shrinking treatment working fluid, and raise temperature to 70 degrees C at heating rate of 1 degrees C/minute at cooling rate of 1.5 degrees C/minute, cooling down to 50-60 degrees C. The fabric door width is extended by 2-3 cm, over 5%, and both sides of the fabric and does not wrinkled. The acid 1-2g/L leveling agent TF-217BA, 0.8-1.3g/L dispersing soaping agent TF-2508, 0.8-1.3g/L ammonium sulfate, dye is 5-10% of the fabric weight. The fabric is immersed in weak acid dye solution, heated to 80 degrees C at heating rate of 0.8 degrees C/ minute. The 0.6-1.3g/L of glacial acetic acid is added. then continue to increase the temperature to 0.8 degrees C/minute, increase temperature to 98 degrees C, heat preservation and dyeing for 40 minutes, and then reduce temperature to 50-60 degrees C at decrease rate of 1.5 degrees C/minute, and then drained. The soaping treatment working solution includes 0.5-1.5g/L soaping agent TF-2508. The fabric is subjected to thermal soaping treatment for 5-15 minutes, and drainage. The working liquid is fixed by using 1.5-2.5g/L fixing agent TF-506S. The heat preservation and color fixing treatment is performed on the fabric for 10-20 minutes, and water is drained. The flexible post-treatment post-treatment working fluid is performed by using 15-25g/L hydrophilic softener TF-406. The fabric is subjected to flexible treatment. The stereotype and stereotype working fluid processed by using 45-55g/L fluorine-free waterproof processing agent TF-5016A, 10-20g/L fluorine-free waterproof processing agent TF-569F, 1.5-2.5g/L glacial acetic acid. The fabric is pad-rolled at temperature of 40-50 degrees C and speed of 30-50m/minute, and then dried at temperature of 110-120 degrees C.
