| titleOfInvention | Process for improving polyamide, acrylic, aramid, cellulosic and polyester properties, and modified polymers produced thereby |
| abstract | Methods are provided for treating polyester, polyamide, acrylic, aramid or cellulosic substrates to improve the uniformity of dyeing and to improve the hydrophilic, soil-release, odor-, mildew-, bacterial- and fungal- resistant properties of these substrates. A process for improving the fiber surface properties of polyester polymers, comprising the steps of: (a) contacting a polyester substrate with an aqueous monomer or monomer mixture; (b) slowly adding a polymerization initiator to said contacted polyester substrate heated to a temperature suitable for polymerization over a time period of greater than 3 minutes; and (c) polymerizing said monomers on said contacted polyester substrate to form a surface modified polyester substrate, wherein said monomer mixture comprises a water-soluble vinyl monomer and a cross-linking hydrophobic vinyl monomer, wherein said water-soluble vinyl monomer is selected from the group consisting of N,N'-methylenebisacrylamide, N,N'-(1,2-dihydroxyethylene)bisacrylamide, acrylamine, acrylic acid, 2-propyl-1-ol, crotonic acid, tetraethylene glycol diacrylate, vinylpyridine, methacrylic acid, methacrylamide, 4-methylolacrylamide, N-methyl-N-vinyl formamide, N-vinyl pyrrolidone, 3-methyl-N-vinyl pyrrolidone, 4-methyl-N-vinyl pyrrolidone, 5-methyl-N-vinyl pyrrolidone, maleic acid, vinyl oxyethylformamide, acrylonitrile, methacrylonitrile, methallylalcohol, acrylyl cyanide, styrene sulfonic acid and water-soluble salts of styrene sulfonic acid, wherein said cross-linking hydrophobic vinyl monomer is selected from the group consisting of bisphenol A dimethacrylate, ethylene glycol dimethacrylate, ethoxylated bisphenol A dimethacrylate, allyl acrylate, allyl methacrylate, 1,3-butylene glycol diacrylate, 1,3-butylene glycol dimethacrylate, 1,4-butanediol diacrylate, diallyl fumarate, diethylen glycol diacrylate, 2,2-dimethylpropane 1,3-diacrylate, 2,2-dimethylpropane 1,3-dimethacrylate, dipentaerythritol monohydroxypentaacrylate, ethoxylated bisphenol A diacrylate, 1,6-hexanediol diacrylate, 1,6-hexanediol dimethacrylate, pentaerythritol tetraacrylate, pentaerythritol triacrylate, pentaerythritol tetramethacrylate, trimethylolpropane triacrylate, tri-methylolpropane trimethacrylate, and tripropylene glycol diacrylate, wherein said polymerization initiator is added continuously or portion-wise over a time period ranging from 5 minutes to about 30 minutes, wherein said polymerization initiator is added to an aqueous solution of said water-soluble vinyl monomer in contact with said polyester substrate at a temperature of 80-100 DEG C, wherein said polymerizing is conducted at a pH of about 2-4, and wherein said polymerization initiator is a cationic initiator selected from the group consisting of 2,2'-azobis(N,N'-dimethyleneisobutyrylamidine) dihydrochloride, 2,2'-azobis(2-amidinopropane) dihydrochloride and 2,2'-azobis(N,N'-dimethylenebisisobutyrylamidine). |
