Abstract: A coated abrasive disc includes an abrasive layer disposed on a major surface of a disc backing. The abrasive layer comprises triangular abrasive platelets secured to a major surface of the disc backing by at least one binder material. The triangular abrasive platelets are outwardly disposed from the major surface at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern, wherein the intersections of the rectangular grid pattern have an areal density defined by C/(LT) where C is a unitless coverage factor having a value between 0.1 and 0.4, L is the average major triangular abrasive platelet side length and T is the average triangular abrasive platelet thickness. At least 70 percent of the intersections have a triangular abrasive platelet disposed thereat. Each one of the triangular abrasive platelets has respective top and bottom surfaces connected to each other, and separated by, three sidewalls, and, on a respective basis, one sidewall facing the disc backing of at least 90 percent of the triangular abrasive platelets has a Z-axis rotational orientation within 10 degrees of the vertical lines. Methods of making and using the coated abrasive discs are also disclosed.

Abstract: The provided articles, assemblies, and methods use a non-woven fibrous web (50) having one or more layers (60) that are densified in situ to provide a layer that is densified relative to one or more adjacent layers, collectively within a unitary non-woven construction. The non-woven web (50) can be made from fibers having a composition and/or structure that resist shrinkage induced by polymer crystallization when subjected to high temperatures. Advantageously, the provided non-woven webs (50) can be molded to form a three-dimensional shaped article that displays dimensional stability.

Abstract: A method of making extensible web laminates comprising a multilayer film and at least one web layer and the use of such extensible web laminates in personal care articles. The method generally includes activating the multilayer film in a first direction by stretching at least a portion of the multilayer film past the elastic deformation limit of the skin layers and recovering the skin layers with the elastomeric core layer to produce a multilayer film that is elastic in the first direction. The activated multilayer film is subsequently stretched beyond the deformation limit of the skin layers in a second direction substantially perpendicular to the first direction. At least one web layer is applied to the multilayer film while in the stretched state. The multilayer film is then recovered to produce an extensible web laminate.
