Abstract:
1. A three-dimensional distance woven fabric including two outer fabrics, at least one inter-layered fabric and a plurality of inter-yarns connected with each of the outer fabrics and the inter-layered fabrics, fabricated by a process comprising the step of: providing and transferring a plurality of warps through a warp let-off mechanism including at least one first warp beam and at least two second warp beams; driving and dividing the warps provided by the first warp beam into at least three warp layers by a plurality of heald frames such that a first shed is formed between two adjacent warp layers, wherein a plurality of vertically arranged heald wires are supported by each of the heald frames, each of the heald wires having a heald eye for the warps passing through; transferring wefts to pass through the first shed along a transferring direction by a picking mechanism; pushing the wefts by a beating-up mechanism such that the wefts and the warps are interwoven to form one of the two outer fabrics and the at least one inter-layered fabric located between the two outer fabrics, wherein the heald frames are located between the warp let-off mechanism and the beating-up mechanism; passing through the first shed along a direction substantially parallel to the transferring direction and raising parts of the warps provided by one of the second warp beams by a yarn raising mechanism, wherein the parts of the warps raised by the yarn raising mechanism functions as the plurality of inter-yarns connected with each of the outer fabrics and the inter-layered fabrics, and the yarn raising mechanism is separate from the heald frames; driving and dividing the warps provided by the first warp beam into at least three warp layers by heald frames such that a second shed is formed between two adjacent warp layers; transferring wefts to pass through the second shed along the transferring direction by the picking mechanism; pushing the wefts by the beating-up mechanism such that the wefts and the warps are interwoven to form another one of the two outer fabrics and the at least one inter-layered fabric located between the two outer fabrics; passing through the second shed along the direction substantially parallel to the transferring direction and raising parts of the warps provided by another one of the second warp beams by the yarn raising mechanism; and adjusting and controlling latitude density of the three-dimensional distance woven fabric by a take-up mechanism, wherein a gap distance between the inter-layered fabrics and each one of the outer fabrics is between 20-300 cm.
