    IPC: B24D11/00

    Abstract: A coated abrasive belt (100) includes a belt backing (110) and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements (160) secured to at least a portion of a major surface of the belt backing (110) by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal (192) and vertical lines (194) of a rectangular grid pattern. Each abrasive element has at least two triangular abrasive platelets (130), 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 belt backing A first portion of the abrasive elements is arranged in alternating first rows (16) wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines (194). A second portion of the abrasive elements is arranged in alternating second rows (168) wherein the triangular abrasive platelets (130) are disposed lengthwise aligned with the horizontal lines (194). The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive belt are also disclosed.

    Abstract: Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. When the thermoplastic polyester is selected to include aliphatic and aromatic polyesters, a spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. When the thermoplastic polyester is selected from aliphatic polyesters, a meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

    Abstract translation: 尺寸稳定的非织造纤维幅材包括由一种或多种热塑性聚酯和聚丙烯形成的多种连续纤维，其量大于纸幅重量的0％且不大于10％。 当幅材加热至高于纤维的玻璃化转变温度的温度时，幅材具有至少一个尺寸，其在幅材的平面中减小不超过10％。 当选择热塑性聚酯包括脂族和芳族聚酯时，可以使用纺粘方法来生产显示分子取向的基本连续的纤维。 当热塑性聚酯选自脂肪族聚酯时，可以使用熔喷法制造不显示分子取向的不连续纤维。 纤维网可以用作过滤，吸声，隔热，表面清洁，细胞生长支持，药物递送，个人卫生，医疗服装或伤口敷料的制品。
