Polyester fabrics coated with polymer dyes show bright colors, excellent color fastness and flame retardant properties.
In order to give water-based polyurethane (WPU) bright colors and improve flame retardant resistance, a series of flame retardant, colored WPU (DOWPU) are synthesized by mixing the cymbal hair group (DV26) and phosphorus-containing flame retardant (OP550). At the same time
.
the migration performance, thermal performance and flame retardant properties of DOWPU through a series of experimental systems, which shows that DOWPU has bright colors and satisfactory flame retardant properties.
excellent color fastness and flame retardant
in addition, chemists coated DOWPU on polyester fabrics to prove their usefulness. The coated fabric not only has bright colors, but also exhibits excellent color fastness and flame retardantness.
the work has been published in March 2020 volume 140 of organic paint progress.
