Abstract
A network-like woven 3D fabric material (9) comprises select multilayer warp yarns (8) occurring substantially linearly, the remainder multilayer warp yarns (7) occurring in the helical configuration and two orthogonal sets of weft (12c and 12r) and such a network-like fabric construction (9) made possible through a dual-directional shedding operation of the weaving process. Such a fabric may additionally incorporate non-interlacing multi-directionally oriented yarns (n1-n8) across the fabric cross section to improve the fabric's mechanical performance. The produced 3D fabric material, which may be cut into any desired shape without the risk of splitting, may be used wholly or in parts in technical applications.
Claims7
A device for producing woven material with a weaving method incorporating the operation of shedding in two mutually perpendicular directions to form row-wise and columnwise sheds in the multilayer warp disposed according to the cross-sectional profile of the fabric to be produced, said device comprising shedding means, said shedding means including:
- one or more shafts, each shaft being reciprocable linearly along and angularly about a longitudinal axis;
- each of the shafts include a means for supporting warp yarns extending in a length direction of the shafts such that a length direction of each of the included means is oriented perpendicular to the length direction of said shafts;
- and
- wherein said means supports is the warp yarns threaded through an entry port and an exit port of said means in accordance with the cross-sectional profile of the fabric to be produced.
