摘要： There is provided a nonwoven fabric for use in personal care absorbent articles where the fabric is made from single polymer, helically crimped fibers. Such a fabric provides economical production since it uses only one polymer. These fabrics have superior void volume and resilience and are useful in a number of applications, including as outercovers, liners, surge layers and even as an absorbent core.

摘要： The invention provides a sheet filter medium having autogenously bonded uncrimped conjugate fibers which contain a polyolefin and another thermoplastic polymer that have different melting points. The filter medium has a density between about 0.07 g/cm3 and about 0.2 g/cm3. The invention additionally provides a three-dimensionally thermoformed filter medium that has a density between about 0.07 g/cm3 and about 0.5 g/cm3.

摘要： High loft, low density nonwoven webs are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of A/B side by side morphology in an unheated fiber draw unit. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the z-direction and produce a web of loftedmaterial. The resultant material is particularly suitable for use as an insulator. Particulates may be added to the webs if desired.

摘要： A three-dimensional nonwoven web having a regional, bulk density of less than 0.04 grams per cubic centimeter, a top-side base surface that defines an x,y-plane and at least one macroscopic surface feature extending out of the x,y-plane wherein a macroscopic surface feature is characterized as a feature having an apex that extends at least about 1 millimeter above the x,y-plane of the top-side base surface is provided. The macroscopic feature maintains a height of at least 1 millimeter above the x,y-plane of the top-side base surface under a 1.2 kPa load (Pf ) and results in contact of an object resting on the macroscopic feature such that the percent contact area of the nonwoven web with an article resting on the macroscopic surface feature at a 1.2 kPa load (Pf ) is less than 50 percent of the bulk area of the nonwoven web supporting the article.
