Abstract: A multi-ply absorbent product having a wet scrubbing resistance greater than 120 revolutions and a basis weight of between 30 and 50 grams per square meter. A heated adhesive is applied between two single plies/webs, the multiple plies are embossed according to particular parameters, and the embossed webs are compressed with a marrying roll. The adhesive is heated to a temperature of between approximately 32 degrees C. to 66 degrees C. for application between the multiple plies. For each ply, the embossed area generally occupies between approximately 5 to 15% of the total surface area of a surface of the ply, the depth of embossment of the surface is generally between approximately 0.28 and 0.43 centimeters deep, and the embossment of the surface is generally between approximately 0.04 to 0.08 square centimeters in size.

Abstract: A process for manufacturing tissue including providing a first pulp mix, delivering a wet-end additive to the first pulp mix at a first point in the process, forming a tissue web comprising the first pulp mix after the first point in the process, monitoring the tissue web for breaks and preventing delivery of the wet-end additive to the first pulp mix at the first point in response to detecting a break in the monitoring step. In an exemplary embodiment, a switching valve is used to control delivery of the wet-end additive to the first pulp mix.
