Inorganic-fiber woven fabric for construction film material, and construction film material
Abstract
Provided are an inorganic-fiber fabric for a construction membrane material and construction membrane material having excellent resistance to heat damage, great ease of weaving, and high applicability for use in a construction membrane material. An average Al 2 O 3 content of a warp, At, and an average Al 2 O 3 content of a weft, Ay, are 17.5 mass % or more; a mass per unit length of the warp, Tt, and a mass per unit length of the weft, Ty, are within a range of 100 to 600 g/1000 m; a weave density of the warp, Wt, and a weave density of the weft, Wy, are within a range of 10.0 to 55.0 filaments/25 mm; a ratio of Tt to Ty, Tt/Ty, is within a range of 0.66 to 1.50; and At, Ay, Tt, Ty, Wt, and Wy satisfy the following formula (1-1). 316.5 ≤ Wt 1 / 3 × Tt 1 / 2 / ( At / 100 ) + Wy 1 / 3 × Ty 1 / 2 / ( Ay / 100 ) ≤ 550. 0 ( 1 - 1 )
Claims
exact text as granted — not AI-modified1 . An inorganic-fiber fabric for a construction membrane material, wherein
