    • 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.

    • A resilient flexible sanding sponge including a foam backing layer having a layer of abrasive particles distributed along one of its major surfaces that are adhered together and to the backing layer by a layer of flexible adhesive material. That backing layer has about the same flexibility and conformability as the backing layers on prior art sanding sponges, while having a significantly higher tear strength than prior art sanding sponges. That high tear strength backing layer can either be (1) a layer of felted urethane foam; or (2) a layer of foam that encompasses a reinforcing material. When the backing layer is of felted urethane foam the layer of flexible adhesive material can have a major structurally sound portion below the surface along which the layer of abrasive particles is positioned and a minor portion adhering the abrasive particles along that surface to leave large portions of the abrasive particles projecting above the layer of adhesive material where they can effectively abrade a surface over which the sanding sponge is rubbed.
    • 一种弹性柔性砂光海绵,其包括泡沫背衬层,所述泡沫背衬层具有沿着其主要表面之一分布的磨料颗粒层,所述主要表面通过柔性粘合剂材料层粘合在一起,并具有背衬层。 该背衬层具有与现有技术的打磨海绵上的背衬层大致相同的柔性和适应性,同时具有比现有技术的打磨海绵显着更高的撕裂强度。 该高撕裂强度背衬层可以是(1)一层毡状聚氨酯泡沫; 或(2)包围增强材料的泡沫层。 当背衬层是毡状聚氨酯泡沫时,柔性粘合剂材料层可以具有在表面下方的主要结构声音部分,沿着该层的磨料颗粒定位在该表面上,并且次要部分沿着该表面粘附研磨颗粒以留下大部分 磨料颗粒突出在粘合剂材料层的上方,在那里它们可以有效地磨擦砂磨海绵被摩擦的表面。
