Abstract: Absorbent sheet is manufactured utilizing a low charge density debonder composition comprising an imidazolinium surfactant-containing constituent selected from the group consisting of: (i) cationic imidazolinium surfactants with alkylalkenylhydroxy substitution; (ii) zwitterionic imidazolinium surfactants; and (iii) an ion paired surfactant mixture including a zwitterionic imidazolinium surfactant and a cationic surfactant and, in admixture with the imidazolinium surfactant-containing constituent, (iv) a nonionic surfactant.

Abstract: Improvements to absorbent sheet manufacture include spraying a softener onto the web and providing a creping adhesive to a surface of a heated drying cylinder of a Yankee dryer such that a creping adhesive coating is formed, the creping adhesive comprising a poly(aminoamide)epihalohydrin (PAE) resin and a polyvinyl alcohol copolymer, wherein the polyvinyl alcohol copolymer includes functional repeat units selected from carboxylate repeat units, sulfonate repeat units as well as combinations of the comonomers. A preferred PAE resin is fully crosslinked PAE resin.

Abstract: An improved creping adhesive is prepared by first reacting a dibasic carboxylic acid, or its ester, half-ester, or anhydride derivative, with a polyalkylene polyamine, preferably in aqueous solution, under conditions suitable to produce a water soluble polyamide. The water-soluble polyamide is then reacted with an epihalohydrin until substantially fully cross-linked, and stabilized by acidification with phosphoric acid at the end of the polymerization reaction to form a water-soluble poly(aminoamide)-epihalohydrin creping adhesive that is re-wetable and facilitates water spray removal of buildup so as to lengthen the life of the creping blades, with attendant significant decrease in downtime and maintenance.

Abstract: A method for creping a paper web includes applying, separately or together, to a surface of a rotatable creping cylinder, a creping adhesive and at least one creping adhesive modifier which is a polyoxyalkylene resin possessing repeating oxyalkylene groups containing at least 3 carbon atoms. The method further includes the steps of adhering a paper web to the surface of the creping cylinder and removing the paper web from the creping cylinder with a doctor blade to provide a creped paper product.

Abstract: A thermosetting resin composition particularly suitable for surface coatings, including metals, paper and paperboard, and especially those papers subsequently converted into shaped paperboard products, e.g. paper plates and folded cartons, with a high gloss, water and oil resistant surface coating. The composition is suitable also as both an adhesive and coating in metallizing substrates by the transfer of metallic particles from a transfer agent to the substrate. When formulated without solvents or dispersants it is suitable for use as a casting composition or as a molding material. The composition comprises a polymer or copolymer containing carboxylic acid groups; an epoxy compound containing an average of more than one epoxide group per molecule; an ammonium or phosphonium base or salt thereof; and a monomeric carboxylic acid or inorganic acid which extends the useful working life of the composition and imparts a superior glass to the surface of the finished product.

Abstract: This invention relates to a novel microfiber, to a nonwoven web comprising said microfiber, and to a method of preparing said web. The meltblown microfibers have a diameter of less than 150 micrometers. The microfibers are prepared by meltblowing a liquid crystal polymer such as a wholly aromatic polyester amide of p, p' biphenol, p-hydroxybenzoic acid and terephthalic acid or a wholly aromatic polyester amide of 2-hydroxynaphthoic acid, p-aminophenol and terephthalic acid.
