Abstract
A tissue product containing a multi-layered paper web that has at least one outer layer formed from a blend of pulp fibers and synthetic fibers is provided. A polymer latex is also applied to the outer layer of the tissue product. It is believed that the polymer latex and synthetic fibers can fuse together to have a synergistic effect on the strength of the tissue product. In addition, the resulting tissue product can be soft and produce low levels of lint and slough.
Claims46
A method for forming a tissue product, said method comprising;
- forming a multi-layered paper web that includes at least one outer layer, wherein said outer layer comprises a blend of pulp fibers and synthetic fibers in an amount from about 0.1% to about 20% by weight of said layer so that the total amount of synthetic fibers present within said web is from about 0.1% to about 20% by weight;
- drying said multi-layered paper web;
- and
- applying a polymer latex to said outer layer;
- wherein said multi-layered paper web is uncreped.
A method for forming a tissue product, said method comprising;
- forming a multi-layered paper web that includes at least one outer layer, wherein said outer layer comprises a blend of pulp fibers and synthetic multicomponent fibers in an amount from about 0.1% to about 20% by weight of said layer so that the total amount of synthetic multicomponent fibers present within said web is from about 0.1% to about 20% by weight, wherein said synthetic multicomponent fibers have a density imbalance of from about −0.2 to about +0.5 grams per cubic centimeter;
- through-drying said multi-layered paper web;
- and
- thereafter, printing a polymer latex onto said outer layer, said polymer latex having a glass transition temperature of from about −25° C. to about 30° C.;
- wherein said multi-layered paper web is uncreped.
A method for forming a tissue product, said method comprising;
- forming a multi-layered paper web that includes at least one outer layer, wherein said outer layer comprises a blend of pulp fibers and synthetic bicomponent fibers in an amount from about 0.1% to about 10% by weight of said layer so that the total amount of synthetic bicomponent fibers present within said web is from about 0.1% to about 10% by weight, wherein said synthetic bicomponent fibers have a density imbalance of from about −0.2 to about +0.5 grams per cubic centimeter;
- through-drying said multi-layered paper web;
- and
- thereafter, applying a polymer latex to said outer layer, said polymer latex having a glass transition temperature of from about −25° C. to about 30° C.;
- wherein said multi-layered paper web is uncreped.
