Formaldehyde-free durable press finishing agent

Abstract

The present invention relates to a durable press finish composition, which contains a crosslinker for giving wrinkle-free performance to fabrics, a catalyst, and an additive allowing reductions in strength and whiteness of fabrics to be minimized. As the crosslinker, there is used glyoxal containing no formaldehyde. As the catalyst, there is used one selected from aluminum salt, magnesium salt, citric acid and a mixture thereof. As the additive, there is used sodium tetraborate, sodium peroxoborate, sodium chlorite, or sodium hydrogen sulfate.

1 . A durable press finish composition, which comprises: a crosslinker for giving fabrics wrinkle-free performance, which consists of glyoxal dissolved in water at a concentration of 3-10% by weight; an agent for modifying the crosslinker, which is selected from ethylene glycol and diethylene glycol and contained at a molar ratio of 1:1 relative to the glyoxal; a catalyst selected from aluminum sulfate and a mixture of magnesium chloride and citric acid, the aluminum sulfate being contained at a molar ratio of 0.01-0.08 relative to the glyoxal, and the mixture of magnesium chloride and citric acid being contained at a molar ratio of 0.1-0.6 relative to the glyoxal, the citric acid being contained at a molar ratio of 0.1-0.5 relative to the magnesium chloride; and an additive selected from sodium tetraborate, sodium peroxoborate, sodium chlorite and sodium hydrogen sulfate wherein the sodium tetraborate or sodium peroxoborate is contained at a weight ratio of 0.1-0.6% relative to the composition, the sodium chlorite is contained at a weight ratio of 0.01-0.06% relative to the composition, and the sodium hydrogen sulfate is contained at a weight ratio of 0.01-0.08% relative to the composition.
