BLUE DYEING METHOD FOR POLYPROPYLENE FIBER MODIFIED TO HAVE EXCELLENT DYEING FASTNESS

摘要

The present invention relates to a dyeing method for modified polypropylene fiber. More specifically, the present invention: mixes three or more kinds of dye compounds selected from methine-based dye compounds and anthraquinone-based dye compounds at a predetermined combination and content; and attaches the dye to fabric and performs dip dyeing by raising and maintaining the temperature of a salt bath from 108-112C to 128-130C. The blue dyeing method for polypropylene fiber modified to have excellent dyeing fastness is able to: express blue color completely when applied to the polypropylene fiber modified to enable dyeing; and improve washing and friction fastness while having excellent build-up.;COPYRIGHT KIPO 2019
