Patent number: 6610619Abstract: A method of imparting bulk and/or visual aesthetics to a tissue basesheet involves pressing the basesheet with a felt having a raised pattern on it so that the pattern becomes inherent in the sheet. A pattern is stitched into a carrier layer which is joined to a substrate to form the felt. As the basesheet is pressed into the felt, the raised pattern displaces fibers in the sheet, effectively inducing the pattern in the basesheet. The novel felt with a raised patterned layer is also disclosed.Type: GrantFiled: December 28, 2000Date of Patent: August 26, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Charles E.

Patent number: 6524980Abstract: A composite substrate (10) is prepared for reinforcing a bituminous roofing material by securing together a carrier web (12) with a first set (14) of fiberglass rovings bundles and a second set (16) of fiberglass rovings bundles. The carrier web will have a pair of opposed planar surfaces. The web will define a machine direction and a cross machine direction for the substrate, with the first and second sets of rovings bundles each positioned in parallel relationship, with the longitudinal axes defined by the individual rovings of the two sets being in non-parallel relationship to each other when viewed normal to the plane of the web. The bundle sets are maintained in the spaced apart parallel relationships and the non-parallel angular relationship by the adhesive, stitching or other conventional method of securing which holds the substrate together. If a stitching machine is used, the preferred yarn (18) would be a polyester yarn.Type: GrantFiled: October 1, 1999Date of Patent: February 25, 2003Assignee: The Garland Company, Inc.Inventors: Fred A.

Patent number: 6497954Abstract: This invention relates to a method of promoting the adhesion of textiles to rubber compounds through a vinyl compound plasma pre-treatment procedure and a subsequent application of resorcinol-formaldehyde latex (RFL) to the textile surface. The inventive method encompasses a process through which free radicals of compounds comprising strong carbon-carbon bonds form a film over textile films and then covalently bonded to the resin component of the RFL. Such a method thus produces an extremely strong and versatile adhesive that facilitates adhesion between rubber compounds and heretofore unusable or difficult-to-use textiles. The resultant textile/rubber composites are utilized as reinforcements within such materials as automobile tires, fan belts, conveyor belts, and the like. Such materials and composites are also contemplated within this invention.Type: GrantFiled: April 28, 2000Date of Patent: December 24, 2002Assignee: Milliken & CompanyInventors: Brian G. Morin, Dany Felix Maria Michiels, Brenda D. Wentz
