PURPOSE:To obtain a rotational rupture strength superiorly high in tensile strength and feeling property by arranging so that a filament or filamentous woven fabric consisting of 100 weight parts of rock fiber, 10-50 weight parts of organic fiber and 5-50 weight parts of fiber glass is made to be a base material. CONSTITUTION:100 weight parts of rock fiber with abt. 1-7mum fiber diameter and having calcareous and siliceous substances as chief elements, 10-50 or preferably 20-40 weight parts of organic fiber of rayon, cotton or the like and 5-50 weight parts of staple or roving fiber glass with abt. 6-13mum fiber diameter and abt. 3-60mm fiber length are used for a base material. A blended filament blended with these or a twisted filament which is a blended filament of rock fiber and organic fiber twisted together with roving fiber glass is arranged. A filamentous woven fabric of plain weave, twilled weave and sateen weave may be also used. Accordingly, a revolutional rupture strength superiorly high in tensile strength can be had, and a superior feeling property can be realized.
