    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: Aspects of the present disclosure relate to a method of making an abrasive article. The method can include providing a combination of a mesh backing and a fastener. The mesh backing has a first side and a second side and the mesh backing has a fastener disposed on the second side and intertwined through the mesh backing therein. The combination comprises a raised portion on the first side having a first dimension. The method can include calendering the first side of the mesh backing to form a calendered mesh backing such that the raised portion results in a second dimension. The second dimension is less than the first dimension. The method can include depositing a curable make layer precursor on a major surface of the calendered mesh backing, deposing a plurality of abrasive particles onto the curable make layer precursor, and at least partially curing the curable make layer precursor.
