Abstract
An efficient and effective method for treating tissue making stock to make soft tissues involves adding a softening agent to a first papermaking furnish of short fibers, such as eucalyptus fibers. A second papermaking furnish of long fibers, such as softwood fibers, is blended with the short fiber furnish. Thereafter, wet strength agents and/or dry strength agents are added to the blended furnish. The treated furnish is then fed to a headbox and processed into soft tissue in any suitable manner.
