Abstract
A process and product of making a tissue product is provided. For example, the method can comprise (a) providing a first papermaking furnish containing refined softwood fibers; (b) providing a second papermaking furnish containing hardwood fibers; (c) incorporating the first and second papermaking furnishes into a tissue web such that the tissue web has a hardwood layer and a softwood layer; (d) contacting the tissue web with a drying surface so that the hardwood layer is disposed adjacent thereto; and (e) removing the tissue web from the drying surface with a creping blade at a creping pocket angle of less than about 82 degrees.
Claims22
A method of manufacturing a tissue product comprising the following steps:
- (a) providing a first papermaking furnish containing softwood fibers refined with an energy of greater than about 1.5 horsepower-day per ton;
- (b) providing a second papermaking furnish containing hardwood fibers;
- (c) incorporating the first and second papermaking furnishes into a tissue web such that the tissue web has a hardwood layer and a softwood layer;
- (d) contacting the tissue web with a drying surface so that the hardwood layer is disposed adjacent thereto;
- and
- (e) removing the tissue web from the drying surface with a creping blade at a creping pocket angle of less than about 82 degrees.
A method of manufacturing a tissue product comprising the following steps:
- (a) providing a papermaking furnish containing softwood fibers, wherein said softwood fibers are refined with an energy of greater than about 3.0 horsepower-day per ton;
- (b) providing a papermaking furnish containing hardwood fibers;
- (c) depositing the softwood and hardwood furnishes onto a forming surface using a multi-layered headbox box to form a tissue web having a hardwood layer and a softwood layer;
- (d) contacting the tissue web with a drying surface so that the hardwood layer is disposed adjacent thereto;
- and
- (e) removing the tissue web from the drying surface with a creping blade at a creping pocket angle of less than about 80 degrees, wherein the hardwood layer defines an outer surface of the resulting tissue product.
A tissue product formed by the process of:
- (a) providing a first papermaking furnish containing softwood fibers, wherein said softwood fibers are refined with an energy greater than about 1.5 horsepower-day per ton;
- (b) providing a second papermaking furnish containing hardwood fibers;
- (c) incorporating the first and second papermaking furnishes into a tissue web such that the tissue web has a hardwood layer and a softwood layer, wherein said hardwood layer comprises a debonder;
- (d) contacting the tissue web with a drying surface so that the hardwood layer is disposed adjacent thereto;
- and
- (e) removing the tissue web from the drying surface with a creping blade at a creping pocket angle of less than about 82 degrees, wherein the hardwood layer defines an outer surface of the resulting tissue product.
