Claims6
A creping adhesive composition for creping cellulosic webs comprising:
- a) from 5 to 95 weight per-cent of a water soluble acrylamide polymer having sufficient glyoxal-reacted amide substituents and unsubstituted amide groups to be thermosetting with the ratio of the number of said glyoxal reacted amide substituents to unsubstituted amide groups being in excess of 0.06:1, and,
- b) from 5 to 95 per-cent by weight of water soluble polyol having a MW below 3000.
A method for creping cellulosic webs comprising:
- a) applying to a rotating creping cylinder a dilute aqueous solution of a composition comprising:
- 1) from 5 to 95 weight per-cent of a water soluble acrylamide polymer having sufficient glyoxal-reacted amide substituents and unsubstituted amide groups to be thermosetting with the ratio of the number of said glyoxal reacted amide substituents to unsubstituted amide groups being in excess of 0.06:1 and,
- 2) from 5 to 95 per-cent by weight of water soluble polyol having a molecular weight below 3000.
- b) pressing of a cellulosic web against the creping cylinder to effect adhesion of the web to the surface of the cylinder;
- and
- c) dislodging the web from the creping cylinder by contact with a doctor blade.
