Abstract
A smooth, high density tissue. The tissue has a relatively low caliper, as well as high smoothness and high density. The tissue is calendered from a multidensity, through air dried web.
Claims9
A sheet of tissue comprising a macroscopically monoplanar, through air dried multidensity, cellulosic fibrous structure having two opposed faces, wherein both said faces of said tissue have a smoothness less than or equal to about 800 microns and said tissue has a density of at least about 0.110 grams per cubic centimeter.
A process of making smooth through air dried multidensity tissue paper, said process comprising the steps of:
- providing an aqueous dispersion of papermaking fibers;
- providing a water pervious Fourdrinier wire;
- forming an embryonic web of said papermaking fibers on said wire;
- providing a through air drying belt;
- transferring said embryonic web to said through air drying belt;
- blowing air through said web;
- providing a Yankee drying drum;
- drying said web on said Yankee drying drum to a moisture level of about 1.9 to 3.5 percent;
- providing two axially parallel rolls juxtaposed to form a nip therebetween, said nip being suitable for calendering said embryonic web;
- calendering said embryonic web in said nip at said mean moisture level;
- and
- drying said embryonic web to provide a macroscopically monoplanar multidensity tissue, said tissue having a smoothness less than or equal to about 800 microns.
A sheet of tissue comprising a macroscopicahly monoplanar, multidensity, through air dried cellulosic fibrous structure having two opposed faces, wherein both said faces of said tissue have a smoothness less than or equal to about 900 microns, said tissue having a density of at least about 0.130 grams per cubic centimeter.
