Title:
MULTI-AXIALLY ORIENTED THREE-DIMENSIONAL WOVEN FABRIC AND WEAVING THEREOF
Document Type and Number:
Japanese Patent JPH0345746
Kind Code:
A
Abstract:

PURPOSE: To obtain a three-dimensional woven fabric having uniform quality by forming a horizontal weft layer in the lateral direction of gaps between longitudinal core warps arranged in multiple steps and multiple rows and forming an inclined weft layer in the direction of the step and the direction of the row, thereby achieving multi-axial orientation and further improving the isotropy.

CONSTITUTION: The opening motion of longitudinal core warps arranged in multiple steps and multiple rows is controlled by a jacquard machine while opening the bonding warps arranged between the rows of said core warps. Said core warps are lifted or lowered step by step and a weft is horizontally inserted in the direction of step from the top of the uppermost step to the bottom of the lowermost step in a meandering state to form a horizontal weft layer. At the same time, an inclined weft layer is formed by inserting a weft while successively lifting or lowering, one by one, the layer inclined against the directions of step and row of said core warp. The bonding warps are subjected to the next opening to exchange the upper and lower positions and, at the same time, said bonding warps are arranged in parallel along a plane perpendicular to the core warp to form a vertical yarn layer.
