    Abstract: A melt blowing process comprising: (a) providing a thermoplastic polymer material that includes at least one or a plurality of polyester polymers and at least one or a combination of different meltable metal phosphinates; and (b) melt blowing the thermoplastic polymer material into at least one fiber or a plurality of fibers, with each fiber having a diameter or thickness that is less than about 10 microns. The metal phosphinate is in an amount that (a) reduces the viscosity of the polyester polymer and (b) functions as a crystallizing agent, which at least promotes crystallization of the polyester polymer, when the thermoplastic polymer material is melt blown into the at least one fiber. Non-woven and woven fibrous structures can be made using fibers made from this process.

    Abstract: A coated abrasive disc includes an abrasive layer disposed on a major surface of a 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 from the major surface at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern, wherein the intersections of the rectangular grid pattern have an areal density defined by C/(LT) where C is a unitless coverage factor having a value between 0.1 and 0.4, L is the average major triangular abrasive platelet side length and T is the average triangular abrasive platelet thickness. At least 70 percent of the intersections have a triangular abrasive platelet disposed thereat. Each one of the triangular abrasive platelets has respective top and bottom surfaces connected to each other, and separated by, three sidewalls, and, on a respective basis, one sidewall facing the disc backing of at least 90 percent of the triangular abrasive platelets has a Z-axis rotational orientation within 10 degrees of the vertical lines. Methods of making and using the coated abrasive discs 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.
