(57) Tissue paper having a soft, silky, flannel-like tactile feel through incorporation
of an effective amount of a chemical additive such as, for example, a polysiloxane.
Preferably, less than about 2% of such a chemical additive on a dry fiber weight basis,
is incorporated in the tissue paper: more preferably, only about 0.3% or less is so
retained. Tissue paper embodiments of the present invention may further comprise a
quantity of surfactant material to enhance softness and/or surface smoothness and/or
wettability control; and/or a quantity of a binder material such as starch for linting
control. For example, embodiments which would otherwise manifest a significant reduction
in wettability due to incorporated chemical additives may further comprise sufficient
surfactant to at least partially offset the reduction of wettability induced by the
chemical additive: e.g., for toilet tissue embodiments to be sufficiently wettable
to be handled in contemporary sewage handling and disposal systems. Additionally,
for example, embodiments which would otherwise manifest a significant exacerbation
of linting due to such incorporation of chemical additives alone or in combination
with surfactant materials, may further comprise an effective amount of a binder such
as starch to at least partially offset the linting exacerbation effects of the chemical
additive and, if present, surfactant materials.
