  • Publication number: 20220341072
    Abstract: The present invention provides a method of making a nonwoven fabric of continuous fibers that includes forming a nonwoven web on a highly porous woven or knitted forming fabric that defines a pattern of recesses that are bordered by spaced apart filaments extending between the outer surfaces of the fabric and that allows air to pass both downwardly and sidewardly through the forming fabric. Bonded nonwoven webs are formed having protrusions with very low density and high surface area.

  • Publication number: 20220096283
    Abstract: A hollow fiber that extending along at least a portion of the fiber along a longitudinal axis thereof and is defined by an interior wall is provided. Through selective control over the manner in which it is formed, the present inventors have discovered that the hollow fiber can exhibit a unique combination of a high void fraction and small fiber size that makes it particularly suitable for use in certain applications, such as in nonwoven webs for absorbent articles.

  • 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: 20180228659
    Abstract: The present invention relates to a SMS nonwoven laminate having a basis weight of less than about 20 gsm, said nonwoven laminate comprising outer layers of continuous spunbond filaments and an internal layer of from about 18% to about 43%, by weight of the nonwoven laminate of meltblown fibers, said nonwoven laminate having been hydroentangled to create visibly distinct patterns on the surface of at least one of the outer layers of said nonwoven laminate; and wherein prior to said hydroentangling, the content of meltblown fibers in the nonwoven laminate was from about 20% to about 45%, by weight of the nonwoven laminate.

  • Patent number: 8524144
    Abstract: A method and associated apparatus for melt extruding a nonwoven web includes providing a plurality of fibers from an extrusion device. The fibers are conveyed through a diverging profile portion of a fiber drawing unit (FDU) that causes the fibers to spread and expand in the machine direction within the FDU. The fibers are then conveyed through a diverging diffusion chamber spaced from the outlet of the FDU to reduce the velocity of the fibers and further spread the fibers in the machine direction. The fibers may be subjected to an applied electrostatic charge in either the diffusion chamber or the FDU. From the outlet of the diffusion chamber, the fibers are laid onto a forming surface as a nonwoven web.
