Document Type and Number:
WIPO Patent Application WO/2023/286282
Kind Code:
A1
Abstract:
According to the present invention, there is provided a fire retardant and simultaneously dyeing method for polyester-based textiles, the method comprising immersing a polyester-based textile in a processing bath containing a specific quinone red disperse dye and fire retardant phosphoric acid ester amide represented by formula (VII), and heating the textile. According to this method, it is possible to obtain a dyed fire-retardant polyester-based textile having excellent reproducibility because the change in the dyeing speed of the quinone red disperse dye is small despite the presence of the fire retardant.
