Visually perceivable image-forming dye scavenging article
View Patent ↗The present application relates to a visually perceivable image-forming dye scavenging article capable of absorbing and/or inhibiting transfer of fugitive dyes released during laundering, the article comprising (i) a support substrate with an imprint of an image on at least one surface of the substrate; (ii) at least one dye scavenging compound fixably adhered to the imprinted image; (iii) optionally, a film forming agent; (iv) optionally, a cross-linking agent; (v) optionally, a rheology modifying agent; and (vi) optionally, a catalyst to accelerate the polymerization reaction. Also disclosed is a method of manufacturing the article and use of the same.
1. A visually perceivable image-forming dye scavenging article capable of absorbing and/or inhibiting transfer of fugitive dyes released during laundering, the article comprising:
i. a support substrate comprising a desired imprint of an image on at least one surface of said substrate;
ii. a terpolymer of vinylpyrrolidone/vinylacetate/glycidylmethacrylate fixably adhered on to the imprinted image;
iii. a 3,4-epoxy-cyclohexyl-methyl-3,4-epoxycyclohexane-carboxylate fixably adhered to the imprinted image; and
iv. a quaternized vinylpyrolidone/dimethylaminoethyl methacrylate copolymer fixably adhered to the imprinted image.
2. The dye scavenging article according claim 1 , wherein the support substrate is natural fabric, synthetic fabric, natural non-woven fabric and/or synthetic non-woven fabric.
3. The dye scavenging article according to claim 2 , wherein said fabric is spunlaced, spunbonded, thermobonded and/or airlaided.
4. The dye scavenging article according to claim 1 , wherein the support substrate comprises cellulosic fibers, polyolefins, polyesters, starches, modified starches, and combinations thereof.
5. The dye scavenging article according to claim 1 , wherein the support substrate is continuous ring or rectangular fabric sheet.
6. The dye scavenging article according to claim 1 , wherein the imprinted image is selected from the group consisting of pictures, shapes, symbols, trademark, alphabets of any language numerical letters of any language, and combinations thereof.
7. The dye scavenging article according to claim 1 , wherein the imprinted image is means for communicating a message or carrier for information to its users.
8. The dye scavenging article according claim 1 , wherein said quaternized vinylpyrolidone/dimethylaminoethyl methacrylate copolymer has an average molecular weight of from about 500 to about 200,000.
9. The dye scavenging article according claim 1 , further including a film forming agent wherein the molecular weight of said film forming agent is in the range of about 5,000 to about 5,000,000.
