Abstract
Creping adhesives can include one or more crosslinked resins having the chemical formula (O), (P), or (Q), where RX can be a crosslinking moiety, each RY can independently be a substituted or unsubstituted organic diyl moiety, and each A− can independently be an anion. The creping adhesive can have a cylinder probe adhesion of about 100 gram-force to about 300 gram-force. The creping adhesive can have a peel adhesion of about 20 g/cm to about 110 g/cm.
Claims20
A creping adhesive, comprising:
- a functionalized crosslinked resin comprising azetidinium moieties and pendent halohydrin moieties disposed on polyamidoamine backbones, wherein:
- the polyamidoamine backbones are crosslinked by primary crosslinking moieties and propanediyl crosslinking moieties,
- the primary crosslinking moieties are derived from a functionally-symmetric crosslinker, and
- the functionalized crosslinked resin has an azetidinium ratio of 0.3 or less.
