The creped, wet-pressed tissue products have improved physical properties such as high caliper and a low degree of stiffness. The tissue products are manufactured by molding the nascent tissue web to a structuring belt such that the pattern disposed on the fabric is imparted to the web and can be seen by the consumer in the finished product. The molding step occurs immediately prior to creping such that the molded, nascent, web is transferred from the structuring belt to a cylindrical dryer. The dried tissue web is subsequently removed by creping. The structuring belt imparts the tissue web with a plurality of discrete molded elements arranged to form continuous, substantially machine direction (MD) oriented, line elements that provide the products with an aesthetically pleasing appearance and improves certain physical properties of the finished product.
A creped, wet pressed tissue product comprising a first creped, wet pressed tissue ply and a second creped, wet pressed tissue ply, the product having a first and a second surface, the first surface comprising a plurality of discrete molded elements arranged to form continuous, substantially machine direction (MD) oriented, line elements, the product having a basis weight from about 30 to about 60 grams per square meter (gsm), a sheet bulk of about 8.0 cc/g or greater and a Stiffness Index of about 10.0 or less.
A creped, wet pressed tissue product comprising a first creped, wet pressed tissue ply and a second creped, wet pressed tissue ply, the product having a first and a second surface, the first surface comprising a plurality of discrete molded elements arranged to form a plurality of continuous line elements having a sinusoidal wave shape, the plurality of continuous line elements arranged parallel to one another, equally spaced apart in the cross-machine direction (CD) and oriented substantially in the machine direction (MD), the product having a basis weight from about 30 to about 60 grams per square meter (gsm), a sheet bulk of about 8.0 cc/g or greater and a Stiffness Index of about 10.0 or less.
