Publication number: 20210140102Abstract: This invention relates to a carpet tile that includes a polyolefin secondary backing layer. In particular, this invention relates to modular carpet tiles having at least one layer of polyolefin-containing thermoplastic polymer in the secondary backing of the carpet tile. By modifying the composition of the carpet tiles in this manner, the carpet tiles are able to withstand the high temperatures associated with surface printing of the tiles, while still maintaining cold temperature flexibility.Type: ApplicationFiled: January 20, 2021Publication date: May 13, 2021Applicant: Milliken & CompanyInventors: Sara A. Arvidson, Xin Li, Walter A. Scrivens, Nathan A. Mehl, Andrew M. Honohan, Dale R. Williams, Brandon T. Roberts, Franklin S. Love, III, Paul A. Rundquist

Patent number: 10792870Abstract: The application relates to a process for forming a nonwoven composite. The process includes forming a lofty nonwoven layer, obtaining a thermoplastic polymer, and applying the thermoplastic polymer to the second surface of the nonwoven layer, where the thermoplastic polymer is in the form of a molten polymer, semi-molten polymer, or solid film. Next, pressure and optionally heat is applied to the nonwoven layer and thermoplastic polymer, where the thermoplastic polymer and the second surface of the nonwoven layer are subjected to a textured surface forming a plurality of peak regions and a plurality of valley regions in the second surface of the nonwoven layer and embedding a portion of the primary fibers from the nonwoven layer into the thermoplastic polymer within the valley regions. The thermoplastic polymer is cooled forming a thermoplastic film and the nonwoven layer which together form the nonwoven composite.Type: GrantFiled: November 29, 2016Date of Patent: October 6, 2020Assignee: Milliken & CompanyInventors: Sara A. Arvidson, Ryan W. Johnson, Randolph S. Kohlman, Patrick A. Petri

Patent number: 10607589Abstract: The application relates to a nonwoven composite containing a lofty nonwoven layer and a film. The lofty nonwoven layer contains a plurality of primary fibers and defines a plurality of peak regions and a plurality of valley regions. The film contains a thermoplastic polymer and has a peak film thickness in the peak regions of the layer. The film is present on at least a majority of the second surface of the nonwoven layer. Within the valley regions, the film encapsulates a plurality of fibers from the nonwoven layer. The cross-sectional area fraction of total fibers in the film within the valley regions is at least about 8% and the cross-sectional area fraction of total fibers in the film within the peak regions is less than about 5%.Type: GrantFiled: November 29, 2016Date of Patent: March 31, 2020Assignee: Milliken & CompanyInventors: Sara A. Arvidson, Ryan W. Johnson, Randolph S. Kohlman, Patrick A. Petri
