    摘要： This invention relates to erodable agglomerates containing abrasive grains, and, more particularly to abrasive products containing the erodable agglomerates. Conventional coated abrasives typically consist of a single layer of abrasive grain adhered to a backing. It has been found that only up to about 15% of the grains in the layer are actually utilized in removing any of the workpiece. It follows then that about 85% of the grains in the layer are wasted. Furthermore, the backing, one of the more expensive components of the coated abrasive, must also be disposed of before the end of its useful life. To overcome this problem of waste, many attempts have been made to distribute the abrasive grains on the backing in such a manner so that a higher percentage of abrasive grains can be utilized, thus leading to extended life of the coated abrasive product. The extended life further leads to fewer belt or disc changes by the operators, thereby saving time and reducing labor costs. It is apparent that merely depositing a thick layer of abrasive grains on the backing will not solve the problem, because the grains lying below the topmost grains are not likely to be used. This invention provides erodable agglomerates containing individual abrasive grains disposed in an erodable matrix comprising hollow bodies and a binder. The agglomerates are useful for coated abrasives and bonded abrasives. Abrasive products containing the agglomerates provide higher stock removal than abrasive products bearing a single layer of abrasive grains, since the erodable character of the agglomerates allows the sloughing off of spent individual abrasive grains during abrading operations and the exposing of new abrasive grains to the workpiece. The invention also provides a method of preparing the agglomerates of this invention.

    摘要翻译： 本发明涉及含有磨粒的可侵蚀团块，更具体地涉及含有可侵蚀附聚物的磨料产品。 常规的涂覆磨料通常由附着在背衬上的单层磨料颗粒组成。 已经发现，实际上仅使用高达约15％的层中的颗粒去除任何工件。 因此，该层中约85％的晶粒被浪费。 此外，背衬，涂层磨料的更昂贵的部件之一也必须在其使用寿命结束之前被处理。 为了克服这个浪费的问题，已经进行了许多尝试，以这样一种方式将磨料颗粒分布在背衬上，使得可以利用更高百分比的磨料颗粒，从而延长涂层磨料产品的使用寿命。 延长的寿命进一步导致操作者减少皮带或碟片的变化，从而节省时间并降低人工成本。 很明显，只有在背衬上沉积厚的磨粒才能解决问题，因为不可能使用位于最上面的颗粒之下的颗粒。 本发明提供了包含设置在包含中空体和粘合剂的可侵蚀基质中的各个磨粒的可侵蚀附聚物。 附聚物可用于涂覆的研磨剂和粘结的研磨剂。 含有附聚物的研磨产品比具有单层磨料颗粒的磨料产品提供更高的原料去除，因为附聚物的可侵蚀特性允许在研磨操作期间消除单独的磨料颗粒，并将新的磨料颗粒暴露于工件。 本发明还提供了制备本发明的附聚物的方法。

    摘要： This invention relates to articles for cleaning, buffing, conditioning, or restoring surfaces.
    Abrasive articles made from nonwoven fibers have long been used for cleaning floors and other surfaces. Although previously known nonwoven abrasive articles are extremely useful for the purposes for which they are intended, they rapidly lose their efficiency as they become saturated with dirt.
    This invention provides an abrasive article comprising an open, lofty nonwoven web comprising helically crimped synthetic organic fibers. The article can optionally contain stuffer box crimped fibers and melt bondable fibers.
    The presence of helically crimped fibers brings about greater durability and greater capacity for absorbing debris.

    摘要： Methods of making an abrasive article. Abrasive particles are loaded to a distribution tool defining a plurality of slots that are open to an exterior of the tool. The loaded particles are distributed from the distribution tool to a major face of a backing web below the lower side and moving relative to the tool. Some of the loaded particles become oriented in a respective one of the slots and are then dispensed on to the major face. In this regard, during the step of distributing, a plurality of the oriented particles is simultaneously at least partially within a first slot and in contact with major face. In some embodiments, the distribution tool includes a plurality of aligned rings; adjacent ones of the rings are attached to, and longitudinally separated from, one another by one or more spacer bodies.
