Title (EN) MODIFIED VINYLAMINE/VINYLFORMAMIDE POLYMERS FOR USE AS CREPING ADHESIVES
(FR) POLYMERES DE VINYLAMINE/VINYLFORMAMIDE MODIFIES UTILISES COMME ADHESIFS DE CREPAGE
Abstract:
(EN) This invention is method of creping a paper web comprising a) applying to a rotating creping cylinder an adhesive composition having a pH of about 6.5 to about 8 and comprising one or more vinylamine/N-vinyl formamide polymers composed of about 10 to about 99 mole percent vinylamine monomer and about 90 to about 1 mole percent N-vinylformamide monomer; b) pressing the paper web against the creping cylinder to effect adhesion of the paper web to the creping cylinder; and c) dislodging the paper web from the creping cylinder with a doctor blade.
(FR) Cette invention concerne un procédé de crêpage d'une bande de papier consistant: a) à appliquer sur un cylindre à crêper rotatif une composition adhésive dont le pH est compris entre environ 6,5 et environ 8 et qui comprend un ou plusieurs polymères de vinylamine/N-vinyl formamide composés d'environ 10 à environ 99 % en mole de monomère de vinylamine et d'environ 90 à environ 1 % en mole de monomère de N-vinylformamide; b) à presser la bande de papier contre le cylindre à crêper pour que la bande de papier adhère au cylindre à crêper; et c) à retirer la bande de papier du cylindre à crêper à l'aide d'une racle.
