Title:
POLYESTER/NYLON/CATIONIC DYEABLE POLYESTER/SPANDEX FABRIC DYEING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/010357
Kind Code:
A1
Abstract:
A polyester/nylon/cationic dyeable polyester/spandex fabric dyeing method, having the following steps: (1) immersing the fabric in a first dye liquor containing refining emulsifier and disperse dye, adding acid to adjust the pH value to 4.0-5.0, and then treating for 20-60 minutes at 120° C to 135° C temperature; (2) implementing in sequence hot water washing, reduction cleaning, and acid neutralisation of the fabric treated in step (1); (3) immersing the fabric treated in step (2) in a second dye liquor containing cationic dye and acidic dye, adding acid to adjust the pH value to 4.0-6.5, and then treating 30-60 minutes at 110° C to 120° C temperature; (4) implementing room temperature water washing of the fabric treated in step (3), draining away the liquid, and then implementing acidic colour fixation. The present dyeing method has good dyeing fastness and quality, shortens the dyeing time, and reduces the amount of water used, thereby greatly saving energy.
