  • Sizing
    Patent number: 4070319
    Abstract: Sizing bath for a non-woven cellulose based substrate in which the bath has a pH of 2 to 12 and contains as sizing agent at least one anionic latex of at least one copolymer of which the vitreous transition temperature is -40.degree. C. to +120.degree. C. and of which the K value is 55 to 130, the copolymer containing in interpolymerised form:A. 35% to 80% by weight of at least one ester of acrylic and/or methacrylic acid with an alcohol containing 1 to 18 carbon atoms and/or at least one vinyl ester of a carboxylic acid containing 1 to 18 carbon atoms,B. 20% to 50% by weight of acrylic, methacrylic, crotonic or itaconic acid, or a mixture thereof,C. 0% to 20% by weight of at least one monomer having an ethylene linkage and at least one polar group or containing several ethylene linkages,D.

  • Pigmentary printing pastes for textiles
    Patent number: 3978016
    Abstract: Aqueous pigmentary printing pastes for textile fibers containing a pigment and a thickener in which the thickener is a latex, having a proportion of dry material of from 30% to 50%, of a water-soluble copolymer having a glass transition temperature of from 20.degree.C to 100.degree.C and containing in interpolymerized form the following components: (a) 40% to 60% by weight of acrylic acid, methacrylic acid, crotonic acid or mixtures thereof; (b) 10% to 30% by weight of a vinyl ester of an organic or mineral acid; (c) 50% to 30% by weight of one or more ethylenic monomers, other than the above-mentioned esters, which form water-insoluble homopolymers; (d) 0% to 5% by weight of one or more monomers containing an ethylenic linkage and one or more polar groups; and (e) 0% to 5% by weight of one or more monomers containing several ethylenic linkages; the proportion of said latex in the pastes being 0.5% to 15% and said copolymers being partially or totally neutralized.
