Patent number: 11946169Abstract: A process for making a spunmelt nonwoven web including the steps of providing a mixture of recycled polypropylene, extruding the recycled polypropylene mixture to form a molten recycled polypropylene mixture, filtering the molten recycled polypropylene mixture through a filter to form recycled polypropylene filtrate, dosing the recycled polypropylene filtrate into the spunmelt production line by an amount of 80% to 100% by weight, passing the recycled polypropylene filtrate through at least one spinneret of the spunmelt production line to form filaments at a spinning speed of greater than 1200 meters per minute, cooling and drawing the filaments, and depositing the filaments on a moving belt to form at least one layer of the spunmelt nonwoven web made up of 80% by 100% by weight of recycled polypropylene fibers.Type: GrantFiled: June 10, 2021Date of Patent: April 2, 2024Assignee: PFNONWOVENS LLCInventors: Karthik Ramaratnam, John C. Parsons, David John Pung, Anna Elizabeth Macura, Eric Bryan Bond

Patent number: 11148391Abstract: An abrasive wipe includes a spunbond layer that forms a first outer surface of the wipe, a meltblown layer positioned over the spunbond layer so as to form an inner layer of the wipe and an abrasive layer positioned over the meltblown layer so as to form a second outer surface of the wipe. The spunbond layer, the meltblown layer and the abrasive layer are bonded together in a single bonding step, and, in an exemplary embodiment, the abrasive wipe has an MD tensile strength of at least 700 g/cm and a CD tensile strength of at least 500 g/cm.Type: GrantFiled: February 20, 2018Date of Patent: October 19, 2021Assignee: PFNONWOVENS LLCInventors: Paul DeNoia, Karthik Ramaratnam, Michael Kauschke, Peter Zajaczkowski

Patent number: 10426671Abstract: A method of manufacturing a nonwoven including the steps of: forming a nonwoven web substantially comprised of continuous fibers; applying a bonding pattern to said nonwoven web using a smooth roll and a calender roll wherein said bonding pattern comprises a pattern having unbonded areas; and subjecting the side of said nonwoven web contacted by said smooth roll to a hydraulic treatment at a pressure of between 25 and 75 bars and a total energy of about 0.01-0.04 kwhr/kg., wherein said continuous fibers are comprised of between 97% and 98.5% by weight of an olefin resin comprising substantially of polypropylene and between 1.5% and 3% by weight of a whitener.Type: GrantFiled: August 30, 2016Date of Patent: October 1, 2019Assignees: PFNonwovens LLC, The Procter & Gamble CompanyInventors: W. Andrew Coslett, John C. Parsons, Kevin Ronald Kanya

Patent number: 10259192Abstract: The present invention is directed to a nonwoven fabric made from a composite of nonwoven and pulp where the nonwoven has a high loft derived from a heat set three-dimensional relief structure and/or hydroengorged fiber structure. A nonwoven web is hydraulically treated to create a hydroengorged material having an increased loft. Alternatively a nonwoven web is treated to have a heat set three-dimensional relief structure. The treated web is then hydroentangled with pulp to form a cotendered nonwoven/pulp composite fabric.Type: GrantFiled: March 5, 2018Date of Patent: April 16, 2019Assignee: PFNONWOVENS LLCInventors: Michael Kauschke, Mordechai Turi
