Various embodiments disclosed relate to an abrasive sheet. The abrasive sheet includes a first layer including an abrasive major surface and an opposite second layer defining a second major surface. The second major surface includes a plurality of protrusions extending outwardly from the second major surface. The protrusions include a first polymer component having at least one of a Shore A hardness ranging from about 5 to about 100 and a Shore D hardness ranging from about 1 to about 70. The first layer and the second layer are directly joined to each other.

Abrasive sheet including a plurality of protrusions

There is provided an article comprising at least a first surface having: (a) a first binder layer; (b) a plurality of transparent microspheres partially embedded in the first binder layer wherein the transparent microspheres have refractive indices that are less than a refractive index of the first binder layer and wherein the plurality of transparent microspheres consist of microspheres having a refractive index of no more than 1.490. There is also provided a transfer article comprising: (a) a transfer carrier, the transfer carrier comprising: (i) a support layer; and (ii) a thermoplastic release layer bonded to the support layer; (b) a layer of a plurality of transparent microspheres, formed on a side of the thermoplastic transparent microsphere release layer opposite the support layer, wherein the plurality of transparent microspheres consist of microspheres having a refractive index of no more than 1.490.

Microsphere articles and transfer articles

An abrasive article is provided that has a backing having opposed first and second major surfaces, an abrasive layer disposed on the first major surface, and a plurality of protrusions extending outwardly from the second major surface. The protrusions comprise a polymer having a Shore A hardness ranging from 5 to 90. These articles provide an alternative sanding solution enabling abrasive articles lacking an attachment layer to be handled effectively and efficiently, providing for a technically superior abrasive sheet on the marketplace that does not use or require an attachment layer.

Abrasive articles, assemblies, and methods with gripping material

Systems and methods for optimizing body and object interactions are provided. Based on obtained contact pressure maps and coefficient of friction (COF) maps at a contact interface where at least a portion of a body is in physical contact with a surface of an object, friction force maps can be determined, which can be used to optimize body and object interactions.

System and method for optimizing body and object interactions

A polymeric netting includes polymeric strands and first and second polymeric ribbons. The first and second ribbons each independently have a height-to-width aspect ratio of at least three to one and a major surface that is intermittently bonded to a polymeric strand, with first and second edges symmetrically disposed on opposite sides of a center line bisecting the major surface. The netting has first and second opposing major surfaces transverse to the major surfaces of the first and second ribbons. The first major surface of the netting includes the first edges of the first ribbons, and the second major surface includes the second edges of the second ribbons. The first ribbons do not extend to the second major surface, and the second ribbons do not extend to the first major surface. Articles including the netting, an extrusion die, and a method useful for making the netting are also disclosed.

Polymeric netting of strands and first and second ribbons and methods of making the same

A polymeric netting including polymeric ribbons and polymeric strands. Each of the polymeric ribbons and strands has a length and width, with the length being the longest dimension and the width being the shortest dimension. The polymeric ribbons have a height-to-width aspect ratio of at least five to one, a major surface that is intermittently bonded to only one polymeric strand, and a height greater than the height of the one polymeric strand. An extrusion die and method useful for making the polymeric netting are also disclosed.
