THREE-DIMENSIONAL WOVEN FABRIC HAVING UNUSUAL SHAPED CROSS SECTION

摘要

PURPOSE:To obtain a three-dimensional woven fabric of unusual shaped cross section for a panel material fitted with a rib, by constituting yarn in the width direction between the top and the bottom layers of yarn in the length direction arranged in a shape consisting of a flat part with a given width thickness and plural projected parts protrusively set at one side of the flat part and setting vertical yarn between neighboring layers of the yarn in the width direction. CONSTITUTION:In constituting a three-dimensional woven fabric of modified cross section consisting of yarns in the mutually and perpendicularly intersecting length direction, width direction and vertical direction, comprising a flat part having the thickness extending in the length direction and plural lines of projected parts protrusively set at least one side of the flat part, a great number of yarns in the length direction are arranged in parallel with the unusual cross-section shape. Then the yarn in the width direction is inserted into between the layers of the vertically neighboring yarn in the length direction in the whole width at the flat part and in the whole width of the arranged yarn in the length direction at the protruded part while reciprocating the yarn in the width direction. The yarn in the vertical direction is inserted into between the layers of the yarn in the width direction, adjoining in the length direction and the yarn in the length direction and the yarn in the width direction are fastened so that the flat part and the protruded part are integrated.
