    Abstract: A process for treating wool and other proteinaceous material to render it shrinkproof which comprises treating the proteinaceous material with a polymerizable treating solution which contains the reaction product of a diol and a polyisocyanate or a urethane-polyisocyanate, and, thereafter, curing the thus-treated material with water. The reaction product produced contains at least three free NCO groups per molecule. Preferably, the polyisocyanate or urethane-polyisocyanate used contains three isocyanate groups. These isocyanates may be of the polymethylene polyphenyl type, as well as of the type formed by reacting a polyhydroxy compound containing from three to six OH groups with a diisocyanate and, additionally, may also contain from about 0.05 to 3 percent by weight of tertiary nitrogen. The solutions used to treat the proteinaceous material typically contain from about 0.5 to 50 percent by weight of the above compositions. The proteinaceous materials treated with these compositions are found to have an improved hand over those materials which are treated with similar solutions but which contain polyisocyanates or urethane polyisocyanates which have not been reacted with a diol.

    Abstract translation: 一种处理羊毛和其他蛋白质材料以使其收缩的方法，其包括用含有二醇和多异氰酸酯或氨基甲酸酯 - 多异氰酸酯的反应产物的可聚合处理溶液处理蛋白质物质，然后固化如此处理 材料用水。 产生的反应产物每分子含有至少三个游离的NCO基团。 优选使用的多异氰酸酯或聚氨酯聚异氰酸酯含有三个异氰酸酯基团。 这些异氰酸酯可以是聚亚甲基多苯基型，以及通过使含有三个至六个OH基团的多羟基化合物与二异氰酸酯反应而形成的类型，另外还可含有约0.05-3重量％的叔氮 。 用于处理蛋白质材料的溶液通常含有约0.5至50重量％的上述组合物。 发现用这些组合物处理的蛋白质材料比用类似溶液处理但含有未与二醇反应的多异氰酸酯或氨基甲酸酯多异氰酸酯的那些材料具有改进之处。

    Abstract: A PROCESS FOR PREPARING WET-STRENGTH PAPER WHEREIN THE PAPER IS TREATED WITH A CATIONIC THERMOSETTING RESIN COMPRISES OF A WATER-SOLUBLE REACTION PRODUCT OF EPICHLOROHYDRIN AND A POLYAMIDE. THE POLYAMIDE IS THE REACTION PRODUCT OF A NITRILOTRIACETIC ACID AND A POLYALKYLENE POLYAMINE CONTAINING TWO PRIMARY AMINE GROUPS AND AT LEAST ONE SECONDARY AMINE GROUP, THE AMOUNT OF REACTANTS AND TEMPERATURE AND TIME OF REACTION BEING AS FOLLOWS: AN AMOUNT OF NITRILOTRIACETIC ACID SUFFICIENT TO REACT COMPLETELY WITH THE PRIMARY AMINE GROUPS OF THE POLYALKYLENE POLYAMINE REACTANT, BUT INSUFFICIENT TO REACT SUBSTANTIALLY WITH THE SECONDARY AMINE GROUPS; THE REACTION CARRIED OUT AT 25*-50*C. AND FOR 1-3 HOURS WHEN CARRIED OUT AT ATMOSPHERIC PRESSURE.
