摘要:
The present invention provides a method making glass fiber fabric reinforcements, cement boards, and glass fiber coatings for such reinforcements. The glass fiber fabric reinforcement includes a glass fabric containing multiple yarns containing glass filaments and a polymeric coating disposed onto the multiple yarns to form a coated glass fabric. The polymeric coating comprises a polyolefin based copolymer composition whereby the glass fabric has a Gurley Stiffness measurement of about 100-3000 mg and an ASTM D 638 (2% Secant) modulus of compression of about 1-100 MPa. The reinforcement is sufficiently drapable and lacking in shape memory so as to be curved around the edge of a cement board during the manufacture of same.

摘要:
A reinforcement mesh, an architectural moulding reinforced by the mesh, and methods of making the architectural moulding and the mesh. The mesh is adhered by an adhesive to the architectural moulding. In the mesh, weft yarns bend relative to warp yarns to conform to and against a curved profile of the architectural moulding, and the warp yarns are unbent and adhered against the moulding.
摘要:
A method of making a reinforcement sheet for a cementitious board includes applying a hydrophilic coating material on binder coated glass fibers, the hydrophilic coating material being mobile in slurry water at a surface of a slurry of a cementitious compound to dilute and disperse, and to wet and spread the slurry on the binder coated glass fibers, and the hydrophilic coating material in the slurry water being volatile to dissipate by evaporation at an elevated temperature at which the cementitious compound is dried for the binder coated glass fibers to be essentially free of the hydrophilic coating material.

The present invention provides thickened fabrics and reinforcements for use as a spacer or reinforcement for a matrix system. The fabric includes in a first embodiment a woven fabric comprising weft and warp yarns containing glass fibers. A portion of the weft yarns are undulated into a sinusoidal path forming a generally “C” shaped bridge between adjacent warp yarns which results in an increased thickness for the fabric. The fabric is coated with a polymeric resin or bonding agent, for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making such fabric by increasing the thickness of a woven or non-woven material by such methods as applying tension to warp yarns having opposite twists during weaving operations, or using unbalanced yarns, for example.
