A lapping material having a knitted fabric constituted by warp knitting or weft knitting, and a resin with which the knitted fabric is impregnated.

An abrasive article includes backing material, binder comprising an anionic water solubilizing material provided on at least a portion of the backing material and abrasive particles provided on at least a portion of the backing material. A method of making such an abrasive article comprises the steps of providing a backing material, applying a first binder containing an anionic water solubilizing material to the backing material, and applying abrasive particles to the backing material.

A polishing tool with a carrier comprising a polishing surface on which a polishing paste is applied at least in some areas, wherein the polishing surface consists of a nonwoven fabric, the polishing paste is in a solid state at room temperature and is applied on the polishing surface to be covered in an amount of 0.08 g/cm.sup.2 to 0.30 g/cm.sup.2.

A probe pin cleaning sheet with cleaning power and a manufacturing method thereof are disclosed, comprising a release layer, a cleaning layer, and a substrate. Thus, in the process that the probe pin pierces the cleaning layer, through the material of cleaning layer, and the cleaning grains of abrasive material contained in the cleaning material in the cleaning layer, the cleaning power is increased to scrape off dirt from the surface of probe pin. In addition, by the negative charges and lipophilic property of the silicone itself, the dirt on the probe pin can be transferred onto the cleaning layer.

Provided are a pressure-sensitive adhesive tape, a polishing pad, a method of manufacturing the same, a polishing device and a method of manufacturing a glass substrate. The illustrative pressure-sensitive adhesive tape may be a pressure-sensitive adhesive tape for a polishing material. The pressure-sensitive adhesive tape may be effectively fixed to a surface plate without bubbles, and have excellent resistance to water and a polishing solution and shear strength applied in a polishing process. In addition, the pressure-sensitive adhesive tape may be easily removed from a carrier or surface plate for a polishing pad without residues after polishing.

Provided are abrasive articles, and related methods, that include a flexible abrasive layer having opposed first and second major surfaces, a foam backing bonded to the second major surface, the foam backing being resiliently compressible, and a plurality of slits disposed on the first major surface and penetrating through the flexible abrasive layer and at least partially through the foam backing. In further disclosed embodiments, the abrasive article includes, a flexible abrasive layer having opposed first and second major surfaces, a structured member extending across the second major surface of the flexible abrasive layer, where the structured member and the flexible abrasive layer have respective three-dimensional patterns of discrete, isolated wells that correspond to each other, and a foam backing extending across a major surface of the structured member opposite the flexible abrasive layer, the foam backing being resiliently compressible.

Provided are multilayered abrasive articles that include an abrasive composite having shaped features, a carrier film, and a nonwoven web, where the nonwoven web and the carrier film have respective patterns of discrete, three-dimensional protrusions that are aligned with each other. A compressible foam backing extending across a major surface of the nonwoven web opposite the carrier film. Further provided are multilayered abrasive articles that include an abrasive composite, a carrier film, and a non-woven web. The nonwoven web and the carrier film have respective patterns of discrete, three-dimensional protrusions that are aligned with each other and the shaped features and the three-dimensional protrusions of the nonwoven web have an average diameter:average diameter ratio ranging from 1:50 to 1:5.

A sanding apparatus includes a flexible base member which includes a base member bottom side and a base member top side. A quantity of abrasive material is attached to the base member bottom side. A flexible handle is positioned above the base member top side, and attachment means are provided for attaching the flexible base member to the flexible handle. The flexible handle includes a pair of parallel (opposing side) finger grip grooves. The flexible handle also includes a plurality of finger grip indentations located on each side of top edge of the flexible handle to provide a more comfortable gripping of the flexible handle.

Abrasive articles including a nonwoven fibrous substrate having a plurality of fibers, and a multiplicity of shaped abrasive particles, each shaped abrasive particle adhered to a corresponding fiber, each shaped abrasive particle having a length (L) and a width (W) determined in a direction substantially orthogonal to the length, the ratio of the length to the width defining an aspect ratio (L/W) of at least 1.1, each abrasive particle is oriented relative to its corresponding fiber, and more than 50% of the abrasive particles are oriented with respect to their corresponding fiber such that the abrasive particle length extends generally outwardly away from a surface of the corresponding fiber as determined visually using the Orientation Test. The shaped abrasive particles may have the geometric shape of a polygonal prism having two faces and at least three sides thereon. Methods of making the abrasive articles are also disclosed.
