Title:
THREE-DIMENSIONALLY WOVEN FABRIC
Document Type and Number:
Japanese Patent JPH05148735
Kind Code:
A
Abstract:

PURPOSE: To obtain a three-dimensionally woven fabric capable of detecting the change of the form in the woven fabric by sterically arranging continuous fibers containing continuous fibers having excellent light-transmittance and extending both ends of the light-transmitting fiber to the circumferential edges of the woven fabric.

CONSTITUTION: The objective three-dimensionally woven fabric is formed of a warp layers composed of warps Z arranged parallel to the longitudinal direction of the woven fabric, a weft layers composed of wefts X arranged in the direction of the width perpendicular to the warps Z and vertical fibers Y perpendicularly passing through both layers. A part of the warps Z are replaced with plastic optical fibers 1 having excellent light-transmittance and both ends of the optical fiber are extended from the outer circumference of the woven fabric. As an alternative, a part of the warps Z and optical fibers 1 are wound on the outer circumference of a fixing members placed at the end parts of the woven fabric and the optical fibers 1 are extended to the outside of the circumference of the woven fabric. In the case of using the three- dimensionally woven fabric as a filter, the outer circumference of the woven fabric is fixed to a frame, the ends of the optical fibers 1 are connected to a light-projection unit 2 and a light-receiving unit 3 and the strain in the woven fabric is detected by detecting the change of light intensity at the outlet side.
