    摘要: A binder composition for nonwoven fabrics which comprises(a) a fugitive base salt of a phosphate ester surfactant or a carboxylate surfactant,(b) a latex comprising a vinyl acetate-ethylene-olefinically unsaturated carboxylic acid interpolymer colloidally suspended in water, the interpolymer containing about 0.5 to 7.0 weight percent olefinically unsaturated carboxylic acid and sufficient ethylene to provide the interpolymer with a glass transition temperature of from about -30.degree. to +20.degree. C., and(c) a polyvalent metal complex compound comprising a polyvalent metal ion and counter ions or ligands which hinder interaction of the polyvalent metal ion with the carboxylate and phosphate groups of the surfactant and interpolymer at room temperature, but at elevated temperature permit such interaction because the counter ions or ligands are expelled or are replaced by the anionic group of the surfactant and interpolymer.Nonwoven fabrics, particularly diaper innerliners, bonded with such binder compositions possess good dry and wet tensile strengths and good low rewet properties.

    摘要: Nonwoven fibrous sheets impregnated with latices of polyvinyl acetate or its copolymers containing polyvinyl alcohol, intended for use in pre-moistened condition as skin cleansing tissues, are folded and packaged in closed containers or in individual sealed water impervious envelopes; said packaged sheets being maintained in contact with a dilute aqueous solution of a precipitating or gelling agent for polyvinyl alcohol, such as boric acid. The agent imparts improved wet tensile strength to the sheet during storage and use by the consumer but permits the sheet to be safely disposed of, after use, by flushing in plain water without danger of clogging the plumbing system.

    摘要: The wet strength of cellulosic paper is improved by adding the combination of an amine-functional poly(vinyl alcohol) and a cellulose reactive size which is a 4 or 5 membered cyclic ester or anhydride having alkyl or alkenyl substituents of 4 or more carbon atoms. The amine-functional polymer is preferably a hydrolyzed copolymer of vinyl acetate and N-vinylformamide in which about 1-25 mole % of the monomer units are incorporated N-vinylformamide, and the cellulose reactive size is preferably an alkyl ketene dimer or an alkenyl succinic anhydride. A paper product is provided having improved wet-strength and containing normally 0.05 to 4.0 wt % based on the dry pulp of the additive amine-functional polymer and cellulose reactive size. The particular compounds which represent the polymer and the size cooperate to provide improvements in wet-tensile strength for paper which could not have been foreseen from the effects of either material acting alone.

    摘要: Nonwoven fibrous sheets bonded with polyvinyl alcohol, intended for use in pre-moistened condition as skin cleansing tissues, are folded and packaged in closed containers or in individual sealed water impervious envelopes; said packaged sheets being maintained in contact with a dilute aqueous solution of boric acid. The boric acid imparts improved wet tensile strength to the sheet during storage and use by the consumer but may be safely disposed of, after use, by flushing in plain water without danger of clogging the plumbing system. Instead of boric acid solution, one may employ for the indicated purpose a non-alkaline aqueous solution of a salt which acts as a precipitating or gelling agent for polyvinyl alcohol, said salt being one having an acid to neutral pH on hydrolysis.

    摘要: Aqueous emulsions containing an ethylene-vinyl chloride (EVCl) copolymer and tetramethylol glycoluril are described for use as binder compositions suitable for application onto nonbonded filter paper. The emulsions are prepared by incorporating 4 to 10 wt % tetramethylol glycoluril, based on the total weight of the emulsion copolymer, into an aqueous dispersion of a copolymer consisting essentially of 65 to 90 wt % vinyl chloride, 5 to 35 wt % ethylene and optionally, up to 10 wt % of a hydroxyalkyl- or carboxylic acid-containing functional comonomer. The polymerization is conducted in the presence of a stabilizing system consisting essentially of 3 to 15 wt % polyvinyl alcohol. Filter paper impregnated with these emulsions maintain tensile strength and flexibility upon being subjected to hot oil.
