The invention provides a glass fiber facing sheet for engineered surfaces such as cement boards which reduces the pitting associated with open mesh glass scrims. The glass fiber facing sheet comprises an open mesh glass scrim having a plurality of intersecting continuous multifilament yarns which are bonded at their crossover points to provide dimensional stability to the scrim. A melt blown polymer web is preferably joined to one face of the glass scrim and covers the mesh openings in the scrim. The opposed face of the scrim defines an exposed grid profile surface which is available for mechanical interaction between the scrim and the cementitious slurry used in cement boards. In cement boards, the glass fiber facing sheet of the present invention is preferably mechanically integrated into a surface portion of the cement core along the exposed grid profile of the scrim. A second facing sheet may also be mechanically integrated into an opposed surface portion of the cement core and contain a melt blown polymer web joined to one face. The present invention further includes a method of making the glass fiber facing sheet of the invention and a method of making a smooth cement board containing the glass fiber facing sheet of the invention.

Thin nonwoven fabrics of high resistance to elongation are produced by bonding fibrous webs comprising staple thermoplastic fibers to each face of a spun-bonded web of entangled and interlaced continuous filaments, wherein substantially all of the filaments of the spun-bonded web are in bonding contact with the thermoplastic fibers of the fibrous webs.

Non-woven fabrics

Nonwoven fabrics of improved abrasion resistance are produced by applying to a dry-laid fibrous web an aqueous dispersion of ultra-short fibers of 50 to 300 microns in length, said ultra-short fibers being coated with a polymeric binder and being suspended in an aqueous phase which is substantially free of binder. The dry-laid fibrous web may be bonded in a separate operation, optionally with a different polymeric binder and in a discontinuous pattern.
