    摘要: An open low-density abrasive article comprising in combination:(a) a lofty, open, nonwoven three-dimensional fibrous web formed of a plurality of interentangled randomly-extending polyamide staple fibers including points of intersection and contact between the fibers, the points of intersection and contact between the fibers being bonded together to form a three-dimensionally integrated structure throughout the web, wherein the fibers comprise surfaces and a fiber tenacity of less than 5 g/denier; (b) abrasive particles dispersed throughout the web and securely adhered to the surfaces of the fibers; and (c) resinous material dispersed throughout the web comprising (i) a hard phenolic resin formed as a cured product of a phenolic resin precursor distributed throughout the web and in contact with the fibers, and (ii) a modifier component of the type and in an amount effective to substantially prevent chemical degradation of the fibers while in contact with the phenolic resin precursor. The invention also relates to methods of making such an abrasive article and converted forms of the abrasive article.

    摘要: A method for making a nonwoven a abrasive article. A preferred aspect of the method comprises the steps of: a) providing a nonwoven web having a first side and a second side, the web comprising a plurality of fibers; b) frothing a liquid make coat precursor; c) applying the frothed make coat precursor to at least the first side of the web in such a manner so as to achieve a substantially uniform coating of the make coat precursor along the fibers of the web; d) spraying a plurality of fine abrasive particles onto the first side of the web, wherein the particles are sprayed so as to form a cloud of abrasive particles that deposit onto the fibers of the web in a substantially uniform distribution; and e) curing the make coat precursor to thereby form a hardened make coat which adheres the abrasive particles to the web and wherein the abrasive particles substantially protrude from the outer surface of the hardened make coat.

    摘要: A method for manufacturing a foraminous abrasive article whereby abrasive particles are concentrated in an external surface region of a foraminous substrate. The method includes the steps of: providing a foamable, hardenable, liquid resin composition and a foraminous substrate having an external surface; foaming the resin composition effective to disperse a plurality of gas bubbles throughout the resin composition; applying the foamed resin composition to the external surface of the substrate to form a foam coating layer having an upper surface; applying a plurality of abrasive particles to the upper surface of the foam coating layer; heating the foamed coating layer effective to eliminate the gas bubbles from the foamed coating layer; and hardening the resin composition to attach the abrasive particles to the substrate. The invention also concerns the foraminous abrasive article products of this method.
