    摘要: A process for making a cellulosic pulp fiber web having increased wet strength comprising the steps of: (1) adding to an aqueous cellulosic pulp fiber slurry a water soluble cationic polymer consisting of polydimethyldiallylammonium chloride to form a first treated slurry; (2) adding to the first treated slurry an aminopolyamide-epichlorohydrin acid salt resin solution having an E/N ratio of from about 0.6 to about 2.0 so that the weight percent of the cationic polymer is from about 1% to about 35% based on the weight of the resin, thus forming a second treated slurry; and (3) forming a cellulosic pulp fiber web by dewatering the second treated slurry.

    摘要: Defoamers are the products of the reaction of epichlorohydrin and compounds having the formula II R3(EO)n(PO)mOH  (II) wherein R3 is an alkyl, alkenyl or arenyl group having from 4 to 22 carbon atoms; a substituted alkyl or alkenyl group having from 4 to 22 carbon atoms wherein; n is a number from 0 to 50 and m is a number from 0 to 10; wherein the mole ratio of epichlorohydrin to (II) is from about 0.60/1 to about 2/1 are extremely efficient defoamers for aqueous surfactant systems. The defoamers are added to a surfactant in an amount sufficient to reduce or eliminate foam and have the advantage of being totally dispersible in water, are readily biodegradable, contain no organic solvents and do not affect the detergency of surfactants with which they are used because they are nonionic surfactants in themselves.
