Publication number: 20250129544Abstract: A carpet tile, includes a pile fabric layer, a primary backing coupled with the pile fabric layer, a secondary backing coupled with the primary backing, and a nonwoven mat. The nonwoven mat includes a glass fiber rich layer having at least 80 weight percent of the glass fibers and a synthetic fiber rich layer having at least 80 weight percent of the synthetic fibers. The nonwoven mat also includes an emulsion binder that is applied to the glass fiber rich layer and the synthetic fiber rich layer to bind the glass fibers and synthetic fibers in said layers together. The nonwoven mat includes at least 10 weight percent of the binder and the binder is curable at a maximum temperature of below 330 degrees Fahrenheit. A total weight percent of glass fibers in the glass fiber rich layer and the synthetic fiber rich layer is at least 48 percent.Type: ApplicationFiled: November 4, 2024Publication date: April 24, 2025Inventors: Zhihua Guo, Philip Christopher Sharpe, Richard T.

Publication number: 20240057801Abstract: A carpet tile includes a textile top member and a cushion mat that is coupled with the textile top member via a thermoplastic material. The textile top member includes carpet yarns and a backing that is coupled with the carpet yarns so that the backing structurally supports the carpet yarns. The cushion mat includes a polymeric material component having polymer fibers that are randomly oriented and entangled together and a scrim reinforcement that is disposed within the polymeric material component. The scrim reinforcement reinforces and stabilizes the polymeric material component and is entirely covered and concealed by the intermeshed polymer fibers.Type: ApplicationFiled: November 2, 2023Publication date: February 22, 2024Inventors: Heath H. Himstedt, Souvik Nandi, Katelyn Grace Horn, Philip Christopher Sharpe

Patent number: 11814785Abstract: A carpet tile includes a textile top member and a carrier mat that is coupled with the textile top member via a thermoplastic material. The textile top member includes carpet yarns and a backing that is coupled with the carpet yarns so that the backing structurally supports the carpet yarns. The carrier mat includes a polymeric material component, a reinforcement, and a binder that is uniformly distributed throughout the polymeric material component and reinforcement component. The polymeric material component includes polymer fibers that are randomly oriented and entangled together. The reinforcement is disposed within the polymeric material component so that the reinforcement is entirely covered and concealed by the entangled polymer fibers to prevent exposure to a user. The reinforcement mechanically reinforces and stabilizes the polymeric material component and carpet tile.Type: GrantFiled: January 20, 2023Date of Patent: November 14, 2023Assignee: Johns ManvilleInventors: Heath H Himstedt, Souvik Nandi, Philip Christopher Sharpe
