Plasma treatments for coloration of textiles, fibers and other substrates

Abstract

A construct, for use in articles like apparel, footwear, backpacks, etc., the construct including a substrate, e.g., a textile, foam, leather or rubber material, having a surface of plasma transformed textile material; colorant set in the plasma transformed textile material, providing a change to the color of the underlying substrate material; and wherein the colorant and the plasma transformed substrate material are chemically bonded together.

         3 . The construct of  claim 1  wherein the colorant is selected from the group of: acid dyes, basic dyes, disperse dyes, direct or substantive, mordant and chrome, pigment, organic, solvent, azoic, sulfur, acetate rayon dyes, nylon dyes, cellulose acetate dyes, and vat dyes. 
     
     
         4 . The construct of  claim 1  wherein the colorant is selected from the group of: azo dyes, anthraquinone dyes, benzodifuranone dyes, polycyclic aromatic carbonyl dyes, indigoid dyes, polymethine and related dyes, styryl dyes, di- and tri-aryl carbonium dyes, phthalocyanine dyes, quinophthalone dyes, sulfur dyes, nitro and nitroso dyes, and miscellaneous dyes. 
     
     
         5 . The construct of  claim 1  wherein the colorant comprises a layer of polymer material. 
     
     
         6 . An item of apparel or footwear, comprising:
 a construct according to  claim 1 .   
     
     
         7 . A construct, comprising;
 a plasma transformed substrate material;   colorant set in the plasma transformed substrate material, providing a color change to the underlying substrate material; and   wherein the colorant and the plasma transformed substrate material are chemically, permanently bonded together such that the affixing of the colorant to the substrate provides a wash durable coating on the substrate without the affixed colorant negatively affecting the bulk properties of the substrate.   
     
     
         8 . The construct of  claim 7  wherein the colorant is selected from the group of: acid dyes, basic dyes, disperse dyes, direct or substantive, mordant and chrome, pigment, organic, solvent, azoic, sulfur, acetate rayon dyes, nylon dyes, cellulose acetate dyes, and vat dyes. 
     
     
         9 . The construct of  claim 7  wherein the colorant is selected from the group of: azo dyes, anthraquinone dyes, benzodifuranone dyes, polycyclic aromatic carbonyl dyes, indigoid dyes, polymethine and related dyes, styryl dyes, di- and tri-aryl carbonium dyes, phthalocyanine dyes, quinophthalone dyes, sulfur dyes, nitro and nitroso dyes. 
     
     
         10 . The construct of  claim 7  wherein the substrate comprises a textile; and the colorant comprises a polymer coating set at the surface of the textile. 
     
     
         11 . The construct of  claim 1  wherein the substrate comprises a three-dimensional object 
     
     
         12 . The construct of  claim 11  wherein the three-dimensional object comprises at least a portion of an article of footwear, apparel, backpack or other carrier or personal items. 
     
     
         13 . The construct of  claim 1  wherein the substrate comprises a foamed material 
     
     
         14 . The construct of  claim 13  wherein the substrate comprises EVA or PU. 
     
     
         15 . The construct of  claim 1  wherein the substrate comprises natural or synthetic leathers or rubbers. 
     
     
         16 . The construct of  claim 1  wherein the colorant is applied as coating having variable topology. 
     
     
         17 . The construct of  claim 16  wherein the thickness of the coating varies between 1 nm and 1 mm 
     
     
         18 . The construct of  claim 10  wherein the coating has variable topology. 
     
     
         19 . The construct of  claim 1  wherein the colorant is affixed to the surface of the substrate as a polymer coating, and the coating has a variable topology patterns that is generally coextensive with the coated surface, the variable topology comprising a web, a porous membrane, a network of regularly spaced perforations, or other such non-solid patterns. 
     
     
         20 . The construct of  claim 1  wherein one or more other colorants are affixed to the surface of the plasma transformed textile. 
     
     
         21 . The construct of  claim 10  wherein one or more other colorants are affixed to the surface of the plasma transformed substrate.
