    摘要： An abrasive article comprises a porous substrate having openings extending through the porous substrate between first and second opposed major surfaces. An abrasive coating is disposed on only a portion of a first major surface of the porous substrate. The abrasive coating comprises a functional layer disposed on only a portion of a first major surface of the porous substrate, a make layer disposed on at least a portion of the functional layer opposite the porous substrate, and abrasive particles. The functional layer and the make layer independently comprise chemically crosslinked binders. The functional layer fully occludes a first portion the openings and does not fully occlude a second portion of the openings, which permits passage of abraded swarf through the abrasive article. Methods of making the abrasive article are also disclosed.

    摘要： Various embodiments of a filtering face-piece respirator and method of forming such respirator are disclosed. In one or more embodiments, the respirator can include a mask body that includes a first cover web, a second cover web, and filter media disposed between the first cover web and the second cover web. The mask body can also include functional material disposed in a filter region of the mask body, where the functional material can include active particles disposed on an adhesive layer; and a perimeter seal region that defines at least a portion of a perimeter of the mask body. At least two of the first cover web, second cover web, and filter media are connected together in the perimeter seal region. In one or more embodiments, the functional material is not disposed in at least a portion of the perimeter seal region.

    摘要： Various embodiments of a filter cartridge are disclosed. The filter cartridge includes a first filter media layer having first and second major surfaces, a second filter media layer having first and second major surfaces, and a plenum disposed between the first and second filter media layers. The filter cartridge further includes functional material disposed on the first major surface of each of the first and second filter media layers within a filter region of the filter cartridge, where the functional material includes active particles disposed on an adhesive layer; and a perimeter seal region that defines at least a portion of a perimeter of the filter cartridge, where at least the first and second filter media layers are connected together in the perimeter seal region. The functional material is not disposed in at least a portion of the perimeter seal region.
