  • Publication number: 20230098239
    Abstract: An elastomeric bicomponent fiber, including at least one sheath and a core, with non-blocking properties and a garment-like feel is provided. The core includes two or more polypropylene based elastomers and a secondary amide, and the sheath includes a non-elastomeric polyethylene. Further, the sheath can be present as a small portion of the total elastomeric composition, and the secondary amide can be present as a small portion of the core, while forming a bicomponent fiber with non-blocking properties and a garment-like feel, while maintaining good strength characteristics.

  • Publication number: 20230089861
    Abstract: Methods and (articles of manufacture therefrom) including forming an elastic film from a polymer composition; tensioning the elastic film to a stretch ratio of between 2 and 6 in the MD; laminating the elastic film to an extensible facing to provide an elastomeric laminate having a CD hysteresis loss of 70% or less and an MD hysteresis loss of 50% or less.

  • Patent number: 11083816
    Abstract: A nonwoven web that contains a plurality of fibers formed from a polyolefin composition is provided. The polyolefin composition contains a rigid propylene polymer that has a relatively high melting temperature and modulus of elasticity, which can provide good strength and durability to the nonwoven web. The polyolefin composition also contains a ductile propylene polymer that has a relatively high melt flow index, which can help achieve relatively fine fibers that minimize the stiffness of the web. In addition to a rigid and ductile polymer, the polyolefin composition also contains a slip additive (e.g., fatty acid derivative). Among other things, such an additive can even further enhance the overall softness of the composition.

  • Publication number: 20140099469
    Abstract: The present invention provides a nonwoven substrate comprising a fibrous web defining a surface; and a layer of a benefit agent wherein said benefit agent is selected from an additive composition, an enhancement component and combinations thereof; wherein said benefit agent is frothed and bonded to the fibrous web surface through a creping process and wherein said nonwoven substrate demonstrates improvements selected from enhanced tactile feel, enhanced printing, a decrease in hysteresis, an increase in bulk, an increase in elasticity/extensibility, an increase in retractability, a reduction in rugosities and combinations thereof when compared to an untreated substrate.
