ABSTRACT:
Certain alkylamides and alkylimides, such as hydroxy alkylamides, which ordinarily act as softening agents and substantially reduce the tensile strength of the tissue sheet in accordance with the strength/softness curve, have been found to have a significantly lesser effect on the strength of tissue sheets which have been noncompressively dewatered and dried. As a result, soft uncreped throughdried tissue sheets can be made to have a higher strength:softness ratio by incorporating these chemicals into the furnish.
