Abstract: A method that includes coextruding two or more thermoplastic resin streams through a profiled die plate, which die plate is shaped to form a nonplanar film (three dimensional) preferably with a regularly oscillating peak and valley structure that oscillates from a top surface to a bottom surface forming longitudinally extending ridges on both faces of the film. The film is formed by coextruding the film through the oscillating die plate opening causing partitioning of the resins in different zones in the width direction of the film. Flattening of the film results in a film with side-by-side zones formed of different polymers or relative proportions of polymers.

Abstract: A unitary fastener of a thermoplastic resin comprising a base film layer having generally parallel upper and lower major surfaces, arranged in a first direction the base film layer being oriented at least in the first direction. The backing layer having on at least one surface separated surface elements extending at an angle to said first direction. The invention is also related to a method of forming a unitary fastener. The method includes the steps of extruding a thermoplastic resin in a machine direction through a die plate having a continuous base portion cavity and one or more rib cavities extending from the base portion cavity, forming a strip having a base layer and one or more continuous ribs. Scoring or cutting the ribs and at least a surface layer of the base layer forms predetermined separable elements. Inelastically stretching the strip forms separated projections and separated separable surface elements across the strip.

Abstract: The present invention concerns a polymeric film hook netting comprising a continuous film backing having a net section formed of plurality of a first set of thermoplastic strands extending in a first direction and a second set of integral strands extending in a second direction at least one of which strands has upstanding hook elements and a second integral non-net film section.

Abstract: There is provided a fastening tab or side panel for a disposable diaper (herein below sometimes referred to simply as a “fastening tab”) with an opening formed in the fastening tab or side panel base member or a notch on the terminal end of the fastening tab or side panel base member. When an invention fastening tab or side panel of an adult or baby disposable diaper (herein below sometimes referred to simply as a “diaper”) is pulled outward, the fastening tab or side panel in some embodiments can be pulled out by hooking the fastening tab or side panel at an opening (the “opening” formed by a discrete opening or a notch) with a finger. The opening helps the fastening tab to have good handleability on the diaper when the diaper is fixed to a user. A fastening tab having openings or notches, with the side having the notches being attached to the diaper such that the notch forms an “opening”, also distributes forces at the side of the diaper.

Abstract: The present invention concerns a polymeric film hook netting comprising a continuous film backing having a net section formed of plurality of a first set of thermoplastic strands extending in a first direction and a second set of integral strands extending in a second direction at least one of which strands has upstanding hook elements and a second integral non-net film section.

Abstract: Aerogel composites and bonded aerogel composites are described. The aerogel composites include monolithic aerogel material located in cavities between a base layer and a structured layer that is bonded to the base layer. Additional layers may be bonded to the base layer and/or the structured layer to form bonded aerogel composites.

Abstract: The present invention relates to an improved disposable cleaning sheet for removing debris, especially hair from a non-smooth or rough surface, especially fibrous type surfaces such as carpeting or upholstery. The cleaning sheets comprise a fibrous substrate and a plurality of protrusions extending from strand elements embedded within fibrous substrate. The cleaning sheets use the protrusions to dislodge the debris from the surface being cleaned, and the fibrous substrate captures the dislodged debris without a backing for the protrusions interfering with the particle capture of the fibrous substrate. Further, the protrusions are firmly embedded within the fibrous substrate such that they cannot be dislodged from the substrate in use.

Methods of forming the same are also disclosed.
