Patent number: 11970819Abstract: The present disclosure relates to tissue products comprising crosslinked fibers. The tissue products generally have good formation, such as a Formation Index greater than about 20, strength, such as geometric mean tensile strengths greater than about 700 g/3? and high bulk, such as sheet bulks greater than about 10 cc/g. Unlike many prior art crosslinked fibers, the crosslinked softwood pulps of the present invention, which are preferably prepared using a glyoxal based crosslinking reagent, are readily dispersible in water and have relatively low degrees of kink and curl. As such, the fibers are well suited for forming wet-laid tissue products and more particularly wet-laid tissue products having improved physical properties, such as improved bulk.Type: GrantFiled: January 20, 2021Date of Patent: April 30, 2024Inventors: Stephen M. Lindsay, Richmond R. Cohen, Kenneth R. Schueler, Jr., Kenneth J. Zwick

Patent number: 8506545Abstract: An absorbent pad including a chassis having a first side edge and a second side edge. The chassis includes a liquid pervious topsheet and a liquid impervious backsheet. An absorbent system is disposed between the topsheet and the backsheet. An elastic element is disposed along each of the first and second side edges of the chassis and attached to at least one of the topsheet and the backsheet, the elastic elements generating a cupping action so that the absorbent pad is biased towards a cup-like shape. A first side adhesive element is attached to the chassis inwardly from the first side edge of the chassis. A second side adhesive element is attached to the chassis inwardly from the second side edge of the chassis. A central adhesive element is attached to the chassis between the first and second side adhesive elements.Type: GrantFiled: December 24, 2008Date of Patent: August 13, 2013Assignee: First Quality Products, Inc.Inventor: Richmond R.
