Title:

THREE-DIMENSIONAL TEXTILE AND METHOD OF PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/1990/014454

Kind Code:

A1

Abstract:

A three-dimensional textile including a warp layer consisting of a plurality of warp yarns arranged in parallel in the longitudinal direction of the textile, bias yarns arranged obliquely with respect to the longitudinal direction of the textile in a plane parallel to the warp layer, and vertical yarns arranged in the direction of the thickness of the textile while crossing orthogonally the warp. When a composite material is made of such a textile using a resin or the like as a matrix, the deformation by the force in the oblique direction becomes smaller than with the conventional three-axis three-dimensional textile and the range of use as the structural material becomes wider. It is another object of the present invention to provide such a three-dimensional textile having such a yarn arrangement in the bias direction and a method of producing relatively easily the textile. The bias yarn layer consists of a large number of continuous bias yarns arranged in a plane parallel to the warp layer in such a manner as to incline symmetrically with one another with respect to the longitudinal direction of the textile, and two layers form one set. The operation which moves that engagement position of each bias yarn in one set of two layers, in which each bias yarn is in engagement with an engagement portion of a feeding apparatus disposed between a cloth fell position and a bias yarn supply portion, to mutually opposite directions by a specified pitch for each bias yarn layer in the transverse direction of the textile by the action of the feeding apparatus, and insertion of vertical yarns are effected alternately.
