Abstract

Described herein are compositions useful for infusing color into nonwoven polyester containing product and methods to do so. Such compositions and methods comprise use of a color infusion composition comprising an antimigrant polymer; pigment; ammonium polyphosphate; and an anionic surfactant comprising phosphate. In certain embodiments, thermoplastic polymer having a glass transition temperature (Tg) of 93.0° C. or less is used to enhance color infusion.

First claim

What is claimed is:

1 . A composition comprising:
an antimigrant polymer comprising sodium polyacrylate; pigment; ammonium polyphosphate; and an anionic surfactant comprising polyoxyethylene branched tridecyl phosphate.

2 . The composition of claim 1 , wherein the antimigrant polymer has a viscosity of about 900 cps to about 5000 cps.

3 . The composition of claim 2 , wherein the antimigrant polymer has a pH of between 4.5 to 8.0.

4 . The composition of claim 1 , wherein the pigment is present in an amount from about 0.05% to about 20.0%, based on the weight of the composition.

5 . The composition of claim 1 , wherein the ammonium polyphosphate has a pH of about 6.5.

6 . The composition of claim 1 , wherein the ammonium polyphosphate has a viscosity of about 100 mPa·s at 25° C.

7 . A composition comprising:
an antimigrant polymer; pigment; ammonium polyphosphate; a thermoplastic polymer having a glass transition temperature (Tg) of 93.0° C. or less; and an anionic surfactant comprising polyoxyethylene branched tridecyl phosphate.

8 . The composition of claim 7 , wherein the antimigrant polymer has a viscosity of about 900 cps to about 5000 cps.

9 . The composition of claim 8 , wherein the antimigrant polymer has a pH of between 5.5 to 8.0.

10 . The composition of claim 7 , wherein the pigment is present in an amount from about 0.05% to about 20.0%, based on the weight of the composition.

11 . The composition of claim 7 , wherein the thermoplastic polymer is selected from sulfonated polyester, poly(vinyl acetate), acrylic, and vinyl-acrylic.

12 . The composition of claim 7 , wherein the thermoplastic polymer is present in an amount from about 0.001% to about 60.0%, based on the dry weight of the product.

13 . The composition of claim 7 , wherein the ammonium polyphosphate is present in an amount ranging from about 25% to about 35% based on the total dry weight of the composition and wherein the thermoplastic polymer is present in an amount ranging from about 10.5% to about 36% based on the total dry weight of the composition.

14 . A nonwoven polyester product comprising a composition comprising:
an antimigrant polymer comprising an acrylic copolymer; pigment; ammonium polyphosphate; and an anionic surfactant comprising polyoxyethylene branched tridecyl phosphate.

15 . The nonwoven polyester product of claim 14 , wherein the antimigrant polymer has a viscosity of about 900 cps to about 5000 cps; and wherein the antimigrant polymer has a pH of between 5.5 to 8.0.

16 . The nonwoven polyester product of claim 14 , wherein the antimigrant polymer is present in an amount of about 0.1 to about 3.0%, based on the dry weight of the product.

17 . The nonwoven polyester product of claim 14 , wherein the pigment is selected from phthalocyanines, naphthols, arylides, inorganics, inorganic oxides, carbon black, chromium oxide, or combinations thereof.

18 . The nonwoven polyester product of claim 14 , wherein the pigment is present in an amount from about 0.05% to about 20.0%, based on the dry weight of the product.

19 . The nonwoven polyester product of claim 14 , wherein the ammonium polyphosphate has a pH of about 6.5.

20 . The composition of claim 7 , wherein the antimigrant polymer comprises sodium polyacrylate.
