摘要： A through-air bonded nonwoven fabric comprises a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surfaces. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions have a difference in values for an intensive property, wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method, and wherein the second region exhibits a Time to Wick of less than 10 seconds, as measured by the Time to Wick Test Method.

摘要： Fibers can include a polypropylene composition, which can include a metallocene random copolymer of propylene and a comonomer that is an alpha-olefin different from propylene. The metallocene random copolymer can have a comonomer content of from 1.2 wt % to 1.8 wt %, a molecular weight distribution of at least 1.0 and of at most 4.0 obtained without thermal or chemical degradation, and a melting temperature Tmelt of at most 140° C. A nonwoven can include the fibers, and a laminate can include the nonwoven. The fibers can be produced by polymerizing the propylene and comonomer in presence of a metallocene-based polymerization catalyst to obtain the metallocene random copolymer. The polypropylene composition can be melt-extruded to obtain a molten polypropylene stream, which can be extruded from capillaries of a spinneret to obtain filaments. A diameter of the filaments can be rapidly reduced to obtain a final diameter.

摘要： A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, wherein the intensive property is one or more of thickness, basis weight, or volumetric density, and wherein the first surface has a TS7 value different than a TS7 value of the second surface.
