Abstract

The invention provides a device for compensating a warp tension based on stereo loom fabric weave. A stereo loom comprises warp beams, warp yarns from the warp beams penetrate through a heald frame to be interwoven with weft yarns through a layering frame so as to form a fabric. The device for compensating the warp tension comprises tension rollers for vertically moving to perform synchronous compensation on warp extension or shrinkage caused by vertical movement of the heald frame and driving devices of the tension rollers. Each warp beam is correspondingly provided with one tension roller, the warp yarns from the warp beams bypass the tension rollers in a U-shaped mode and then penetrate through the heald frame to be interwoven with weft yarns through the layering frame. The invention further provides a method for compensating the warp tension based on the stereo loom fabric weave. The active compensating method is simple in structure and reliable in performance, can very well adapt to weaving of high performance fiber such as poor-elasticity carbon fiber and can meet the compensating requirement that the stereo loom provided with multiple opening and one heald frame needs frequent stroke change, the loom efficiency and fabric quality are improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a device and method for actively compensating warp tension based on the fabric structure of a three-dimensional loom. Background technique [0002] Carbon fiber textile composites have become an important material because of their light weight, high specific stiffness, excellent fatigue properties, and higher corrosion resistance than common metal alloys. Textile composites are widely used in advanced engineering structures such as aerospace, marine, construction, sports, and automobiles. Three-dimensional textile composites overcome the weaknesses of laminated composites such as poor out-of-plane properties, low interlaminar shear strength and low fracture toughness. The monolithic structure of the 3D fabric improves damage tolerance, eliminates delamination that occurs on laminated 2D structures, and can withstand multiaxial mechanical stress. The three-dimensional ...
