CREPING ADHESIVE COMPOSITIONS AND METHODS OF USING THOSE COMPOSITIONS

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...

Beschreibung
Zusammenfassung:	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. L'invention concerne des améliorations à la fabrication de feuilles absorbantes comprenant la pulvérisation d'un adoucissant sur la bande et le dépôt d'un adhésif de crêpage sur une surface d'un cylindre de séchage chauffé d'un frictionneur de telle sorte qu'un revêtement d'adhésif de crêpage est formé, l'adhésif de crêpage comprenant une résine poly(aminoamide)épihalohydrine (PAE) et un copolymère d'alcool polyvinylique, le copolymère d'alcool polyvinylique comprenant des motifs de répétition fonctionnels choisis parmi des motifs de répétition carboxylate, des motifs de répétition sulfonate ainsi que des combinaisons des comonomères. Une résine PAE préférée est une résine PAE complètement réticulée.
