Abstract:
A fabric structure comprising:at least a first group of flexible yarn densely covering an area, the yarns within the first group following substantially parallel paths in a first direction;at least a second group of flexible yarn densely covering substantially the same area, the yarns within the second group following substantially parallel paths in a second direction;the yarns in the first group arranged to cross the yarns in the second group;a plurality of subgroups of yarn comprising each group, each subgroup comprising a plurality of yarns spaced apart at a repeating cell distance of three or more yarn widths and sparsely covering said area, and the yarns in any one subgroup of the first group are placed in said cell distance offset from a direct overlapping alignment with the yarns in the other subgroups in the first group, and the yarns in any one subgroup of the second group are placed in said cell distance offset from a direct overlapping alignment with the yarns in the other subgroups in the second group;the yarns in a subgroup of the first group oriented in the first direction are alternately placed with the yarns in a subgroup of the second group oriented in the second direction to form a stack, whereby the yarns in the first direction establish crossing points with the yarns in the second direction, each subgroup placed at a different level within the stack and the outermost subgroups defining a top and bottom subgroup;a plurality of connections between the top subgroup of the stack and the bottom subgroup of the stack either directly or through the yarns in other subgroups such that a connection between crossing points of yarn groups occur at from 0.3% to 80% of the total number of crossing points.
