Abstract
Disclosed is a process for making soft tissue paper which includes the steps of wet-laying cellulose fibers to form a web, applying to the wet web, at a fiber consistency level of from about 10% to about 80%, a noncationic surfactant, and then drying and creping the web to form the finished tissue paper. The process may further include the steps of applying an effective quantity of a binder material, such as starch, to the wet web for linting control, and to contribute tensile strength to the tissue paper.
Claims17
A process for making soft tissue paper, said process comprising the steps of:
- (a) wet-laying cellulosic fibers to form a web;
- (b) applying to said web, at a fiber consistency of from about 10% to about 80%, total web weight basis, a sufficient amount of a water-soluble noncationic surfactant such that from about 0.01% to about 2.0% of said noncationic surfactant, based on the dry fiber weight of said tissue paper, is retained by said web;
- (c) applying to said web, at a fiber consistency of from about 10% to about 80%, total web weight basis, a sufficient amount of a starch binder material such that from about 0.01% to about 2.0% of said starch, based on the dry fiber weight of said tissue paper, is retained by said web;
- and
- (d) drying and creping said web;
- wherein said tissue paper has a basis weight of from about 10 to about 65 g/m.sup.2 and a density of less than about 0.60 g/cc.
The process of claim 12 wherein said noncationic surfactant is an alkylglycoside, said alkylglycoside having a melting point of at least about 50.degree. C.;
- and wherein said starch is amioca starch.
