Patent number: 11920268Abstract: A system for preparing a polylactic acid (PLA) spunbond nonwoven fabric is provided. In particular, the system includes a first PLA source configured to provide a stream of molten or semi-molten PLA resin; a spin beam in fluid communication with the first PLA source, the spin beam configured to extrude and draw a plurality of PLA continuous filaments; a collection surface disposed below an outlet of the spin beam onto which the PLA continuous filaments are deposited to form the PLA spunbond nonwoven fabric; a first ionization source positioned and arranged to expose the PLA continuous filaments to ions; and a calender positioned downstream of the first ionization source.Type: GrantFiled: May 18, 2022Date of Patent: March 5, 2024Assignees: Fitesa Simpsonville, Inc., Fitesa Germany GMBHInventors: Gary Drews, Elena Novarino, Jason Hamilton, Alfredo Izzo, David Dudley Newkirk

Patent number: 11623427Abstract: A method of preparing a cleaning wipe having a high sustainable polymer content is provided. The cleaning wipe includes a fibrous layer having fibers of a melt spinnable sustainable polymer; and an abrasive layer having meltblown fibers of a melt spinnable sustainable polymer. The abrasive layer defining an outer surface of the cleaning wipe, and includes a plurality of abrasive structures formed thereon in which the abrasive structures are formed from conglomerated fibers, meltblown shot, fibers having average diameters greater than 4 micrometers and fibers having a tortuous geometry. The melt spinnable sustainable polymer content of the cleaning wipe is at least 50 weight % by weight of the cleaning wipe. A method of preparing the cleaning wipe is also provided.Type: GrantFiled: June 28, 2022Date of Patent: April 11, 2023Assignees: FITESA GERMANY GMBH, FITESA SIMPSONVILLE, INC.Inventors: Gary Drews, Elena Novarino, Stefanie Streich, Jason Hamilton, Stephen Chester, Alfredo Izzo, David Newkirk
