  • Patent number: 11946169
    Abstract: 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.

  • Patent number: 11541629
    Abstract: A nonwoven composite fabric including a first nonwoven layer composed substantially of meltblown fibers, the fibers within the first nonwoven layer having diameters that vary in accordance with a first distribution, a second nonwoven layer composed substantially of meltblown fibers, the fibers within the second nonwoven layer having diameters that vary in accordance with a second distribution, and a third nonwoven layer composed substantially of meltblown fibers, the third nonwoven layer disposed between the first and second nonwoven layers, the fibers within the third nonwoven layer having diameters that vary in accordance with a third distribution that is greater than the first and second distributions.

  • Patent number: 11148391
    Abstract: 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.

  • Patent number: 10426671
    Abstract: 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.

  • Patent number: 10259192
    Abstract: 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.
