Fabric reinforcement and cementitious boards faced with same

A multifilament yarn-based woven, braided, nonwoven mesh-type, or knitted fabric comprising:

• (a) a plurality of warp yarns having a first twist (turns/inch);
• (b) a plurality of weft yarns having a second twist, said second twist being greater than said first twist;
• and
• (c) a resinous coating applied to said plurality of warp and said plurality of weft yarns while the warp yarns are being pulled in tension in a machine direction, such that the weft yarns absorb less of said resinous coating than said weft yarns would absorb if the second twist of said weft yarns was equal to the first twist of said warp yarns.

A multifilament yarn-based woven, braided, nonwoven mesh-type, or knitted fabric suitable for subsequent use as a matrix reinforcement comprising:

• (a) a plurality of warp yarns containing a glass filament having a first twist of about 0-0.3 turns/inch
• (b) a plurality of weft yarns containing a glass filament having a second twist of about .7-1.0 turns/inch;
• and
• (c) a protective resinous coating applied to said plurality of warp and weft yarns after they have been assembled or laid together, such as to produce a weight distribution ratio (WPUcd /WPUmd) of less than about 2.0:1 before said reinforcement is applied to a matrix, said weight distribution ratio created in substantial part by the difference in twists of said warp and weft yarns.

A multifilament yarn-based woven, braided, non-woven mesh-type, or knitted fabric suitable for subsequent use as a matrix comprising:

• (a) a plurality of warp yarns having a first twist (turns/inch);
• (b) a plurality of weft yarns having a second twist;
• and
• (c) a resinous coating applied to said plurality of warp yarns and said plurality of weft yarns after they have been assembled or laid together, such as to produce a coating weight distribution ratio (WPUcd/WPUmd) of less than about 2.0:1 before said fabric is embedded within, or adhesively or mechanically attached to a matrix.
