摘要： A polishing pad having a body comprising fibers embedded in a matrix polymer formed by a reaction of polymer precursors. The fibers define interstices, and the precursors fill these interstices substantially completely before completion of the reaction. The pad may include a thin layer of free fibers at its polishing surface. A segment of at least a portion of the free fibers are embedded in the adjacent body of the polymer and fibers. The fibers may be separate, or in the form of a woven or non-woven web.

摘要： A fire blocking non-woven needlepunched textile structure, comprising a first fiber component containing polyacrylonitrile copolymer with a halogen containing monomer and a second fiber component. The second fiber component is selected such that it supports the first fiber component during burning, optionally including an inorganic filler as a coating for the first and second fiber components. In alternative embodiment, the present invention provides a fire blocking non-woven textile structure containing the above first and second fiber components, blended with a third binder fiber component in the form of a vertically lapped nonwoven structure.
