    Abstract: The present invention pertains to a method to produce a laminated textile product, the product comprising a primary carrier sheet with yarns that form a pile on the front surface thereof, and a secondary carrier sheet adhered to the back surface of the primary carrier sheet, the method comprising providing a lick roller having a mass of molten polymer adhesive at its outer circumference, transporting the primary carrier sheet along the lick roller while its back surface is in contact with the outer circumference of the roller at a contact site, thereby transferring a layer of adhesive to the back surface of the primary carrier sheet, and bringing the secondary sheet in contact with the layer of adhesive to adhere the secondary sheet to the back surface of the primary carrier sheet to produce the laminated textile product, wherein downstream of the contact site between the primary carrier sheet and the lick roller, before the secondary sheet is contacted with the layer of adhesive, cobwebbing of the adhesive between the primary carrier sheet and the lick roller is induced.

    Abstract: There is described a solvent assisted dispersion (SAD) process for preparing an aqueous polycondensate (such as a polyester e.g. uralkyd) dispersion substantially free of solvents, comprising the steps of (a) reacting in a non-protic solvent a mixture of (i) one or more polycondensate monomers, oligomers and/or polymers comprising a plurality of isocyanate-reactive groups; wherein the monomers, oligomers and/or polymers comprises at least 2% by weight (components) of a fully, partially or non-neutralized acid group having a pKa less than 3 (ii) at least one multifunctional isocyanate, to form a mixture of a first (e.g. uralkyd) emulsifier resin and the non-protic solvent; (b) optionally, reacting the first emulsifier resin from step (a) with at least one monomer, oligomer and/or polymer different from component (a) (performance polymer) to form a second (e.g. uralkyd) resin; (c) dispersing the first emulsifier resin from step (a) and/or the second performance resin from step (b) in an aqueous medium to form an aqueous (e.g. uralkyd) dispersion. (d) removing substantially all of the non-protic solvent from the dispersion to form a (e.g. uralkyd) dispersion substantially-free of solvent.

    Abstract translation: 描述了一种溶剂辅助分散体(SAD)方法,用于制备基本上不含溶剂的水性缩聚物(例如聚酯,例如uralkyd)分散体,包括以下步骤:(a)在非质子溶剂中使(i) 包含多个异氰酸酯反应性基团的一种或多种缩聚单体,低聚物和/或聚合物; 其中所述单体,低聚物和/或聚合物包含至少2重量%(组分)的具有pKa小于3的完全,部分或未中和的酸基团(ii)至少一种多官能异氰酸酯,以形成 第一(例如uralkyd)乳化剂树脂和非质子溶剂; (b)任选地使来自步骤(a)的第一乳化剂树脂与至少一种不同于组分(a)(性能聚合物)的单体,低聚物和/或聚合物反应以形成第二(例如uralkyd)树脂; (c)将来自步骤(a)的第一乳化剂树脂和/或来自步骤(b)的第二性能树脂分散在水性介质中以形成水性(例如uralkyd)分散体。 (d)从分散体中基本上除去所有非质子溶剂,以形成基本上不含溶剂的(例如uralkyd)分散体。
