Abstract
Fibrous support intended to be impregnated, the fibers of which are formed 100% of cellulose fibers, characterized in that it presents, before creping or embossing, a wet traction strength of over 2.4 N/15 mm in the cross-machine direction, a water absorption capacity of at least 300% and contains less than 2% dry wet strength 10 agent in comparison with the dry weight of the fibers.
Claims22
A fibrous support intended to be impregnated with liquid, the fibrous support comprising a fibrous part comprising cellulose fibers or, in addition to cellulose fibers, cellulose-based fibers, and wherein the support has, without creping, a wet tensile strength above 2.4 N/15 mm in the cross-machine direction, a water absorption capacity of at least 300%, a klemm index (10 minutes) of above 100 mm, and containing a wet strength agent less than 2% as dry matter compared to the dry weight of the fibers.
