摘要： A method of manufacturing zoned webs can include providing a substrate and transferring the substrate in a machine direction. The method can include modifying the substrate to include a plurality of lanes to provide a modified substrate. The plurality of lanes can include a first lane and a second lane. The first lane can include a first zone and a second zone. The first zone can include an open area greater than an open area of the second zone. The second lane can include a third zone and a fourth zone. The third zone can include an open area greater than an open area of the fourth zone. The first lane and the second lane can be formed such that the first zone in the first lane is staggered in the machine direction from the third zone in the second lane. The method can also include slitting the modified substrate between adjacent lanes in the plurality of lanes to provide zoned webs.

摘要： A color-changing polymeric material is provided. The material is formed from a thermoplastic composition containing a continuous phase that includes a matrix polymer, colorant, microinclusion additive, and nanoinclusion additive, wherein the microinclusion additive and nanoinclusion additive are dispersed within the continuous phase in the form of discrete domains. A porous network is formed in the polymeric material when subjected to a deformational strain in a solid state. The polymeric material exhibits a first color prior to being subjected to the deformational strain and a second color after being subjected to the deformational strain, the first color being different than the second color.

摘要： Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a nonwoven material comprising a plurality of fibers can include a first surface and a second surface. The first surface can be opposite from the second surface. The nonwoven material can include a plurality of nodes extending away from a base plane on the first surface. At least a majority of the plurality of nodes have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.

摘要： A method for making a high topography nonwoven substrate includes generating a foam including water and synthetic binder fibers; depositing the foam on a planar surface; disposing a template form on the foam opposite the planar surface to create a foam/form assembly; heating the foam/form assembly to dry the foam and bind the synthetic binder fibers; and removing the template from the substrate after heating the foam/form assembly, wherein the substrate includes a planar base layer having an X-Y surface and a backside surface opposite the X-Y surface; and a plurality of projection elements integral with and protruding in a Z-direction from the X-Y surface, wherein the projection elements are distributed in both the X- and Y-directions, and wherein the density of a projection element is the same as the density of the base layer.

摘要： A method for forming porous fibers is provided. The fibers are formed from a thermoplastic composition containing a continuous phase, which includes a matrix polymer, and a nanoinclusion additive that is at least partially incompatible with the matrix polymer so that it becomes dispersed within the continuous phase as discrete nano-scale phase domains. The method includes traversing a bundle of the fibers through a multi-stage drawing system that includes at least a first fluidic drawing stage and a second fluidic drawing stage. The first drawing stage employs a first fluidic medium having a first temperature and the second drawing stage employs a second fluidic medium having a second temperature. The first and second temperatures are both lower than the melting temperature of the matrix polymer, and the first temperature is greater than the second temperature.

摘要： A method for forming porous fibers is provided. The fibers are formed from a thermoplastic composition containing a continuous phase, which includes a matrix polymer, and a nanoinclusion additive that is at least partially incompatible with the matrix polymer so that it becomes dispersed within the continuous phase as discrete nano-scale phase domains. The method generally includes traversing a bundle of the fibers over one or more draw bars that are in contact with a fluidic medium (e.g., water). In certain embodiments, for example, the draw bar(s) are submerged in the fluidic medium. The fluidic medium is lower than the melting temperature of the matrix polymer.
