Abstract
The present invention is generally directed to facial tissues having great softness and strength. The facial tissues are made from a multi-layered paper web containing a middle layer of eucalyptus fibers either alone or in combination with polyester fibers. The paper web is made with a debonding agent for producing a web having reduced levels of fiber bonding. Once formed, the paper web is treated on each side with a bonding agent in a preselected pattern. Both sides of the paper web are also creped. In order to create a smooth low friction surface, the paper web is fed through a calendering machine and treated with a friction reducing composition and subsequently dried.
