Kind Code:
A1
Abstract:
The present invention provides: an inorganic-fiber woven fabric for construction film material, said inorganic-fiber woven fabric having excellent resistance to heat damage and excellent weavability and being highly suitable for construction film material purposes; and a construction film material. The average Al2O3 percent content At in the warp constituting the inorganic-fiber woven fabric and the average Al2O3 percent content Ay in the weft constituting the inorganic-fiber woven fabric are 17.5 mass% or more, the mass Tt per unit length of the warp and the mass Ty per unit length of the weft are in the range between 100-600 g/1000 m inclusive, the weave density Wt of the warp and the weave density Wy of the weft are in the range between 10.0-55.0 threads/25 mm inclusive, the ratio of Tt to Ty (Tt/Ty) is in the range between 0.66-1.50 inclusive, and At, Ay, Tt, Ty, Wt, and Wy satisfy expression (1-1). (1-1): 316.5≤Wt1/3×Tt1/2/(At/100)+Wy1/3×Ty1/2/(Ay/100)≤550.0
