    Abstract: A process and apparatus for producing a dimensionally stable melt blown nonwoven fibrous web. The process includes forming a multiplicity of melt blown fibers by passing a molten stream including molecules of at least one thermoplastic semi-crystalline (co)polymer through at least one orifice of a melt-blowing die, subjecting at least a portion of the melt blown fibers to a controlled in-flight heat treatment operation at a temperature below a melting temperature of the at least one thermoplastic semi-crystalline (co)polymer immediately upon exiting from the at least one orifice, and collecting at least some of the melt blown fibers subjected to the controlled in-flight heat treatment operation on a collector to form a non-woven fibrous structure. The nonwoven fibrous structure exhibits a Shrinkage less than a Shrinkage measured on an identically-prepared structure including only fibers not subjected to the controlled in-flight heat treatment operation, and generally less than 15%.

    Abstract: A coated abrasive disc includes a disc backing and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements secured to a major surface of the disc backing by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern. Each abrasive element has two triangular abrasive platelets, each having respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of the triangular abrasive platelets is disposed facing and proximate to the disc backing. A first portion of the abrasive elements is arranged in alternating first rows wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines. A second portion of the abrasive elements is arranged in alternating second rows wherein the triangular abrasive platelets are disposed lengthwise aligned with the horizontal lines. The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive disc are also disclosed.

    Abstract: A coated abrasive disc includes a disc backing having an outer circumference. An abrasive layer is disposed on the 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 at regularly-spaced points along a spiral pattern extending outwardly toward the outer circumference. Each triangular abrasive platelet has respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of at least 90 percent of the triangular abrasive platelets is disposed facing and proximate to the disc backing, and at least 70 percent of the triangular abrasive platelets are disposed in a recurring sequential orientation having an oscillating Z-axis rotational orientation of the first respective sidewall relative to the tangents to the spiral pattern at regularly-spaced points. Methods of making and using the coated abrasive disc are also disclosed.
