Embodiment Construction

[0022] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing, by image 3 , Figure 4 and Figure 5 It can be seen that the multiaxial reinforced weft knitting structure of the present invention includes two weft plain stitches 28, 28', two sets of warp yarns 25, 25', two sets of weft yarns 27, 27', and one set of -45° oblique yarns 26 And a set of +45° diagonal yarn 26'. Warp yarns 25, 25', weft yarns 27, 27' and weft flat stitches 28, 28' are symmetrically configured, oblique yarns 26, 26' are located inside warp yarns 25, 25', and weft yarns 27, 27' are located inside warp yarns 25, 28'. 25' outside; weft yarns 27, 27', warp yarns 25, 25' and oblique yarns 26, 26' are lined into the weft flat stitches 28, 28' in a straight manner, and are respectively covered by their coil posts 29, 29' and the sinker arcs 30, 30' are tied, which enhances the binding ability of the knitting yarn to the warp, weft and obliqu...

Abstract

A multi-axial strengthened weft knitted fabric is composed of two weft flab base stitches, two groups of warp yarns, two groups of weft yarns, a group of +45 deg oblique yarn, and a group of -45-deg oblique yarns. Its knitting method and dedicated apparatus are also disclosed.

Description

Technical field: [0001] The invention relates to a knitted structure, its weaving method and device, in particular to a multiaxial reinforced weft knitted structure, its weaving method and a special flat knitting yarn feeding device. Background technique: [0002] Multi-axial knitted structure is a new type of textile structure in which warp yarn, weft yarn and diagonal yarn are lined in the knitted ground structure. It has excellent plane mechanical properties and is widely used as reinforcement for industrial knitted materials and structural composite materials. . There are currently three types of representative multiaxial knitted structures: the first type is a multiaxial knitted structure woven on a warp knitting machine. In this fabric structure, at least 4 layers of yarn (one layer of weft yarn, One layer of warp yarn, one layer of +45° oblique yarn and one layer of -45° oblique yarn) are lined in parallel into the ground weave. In addition to warp flat weave, the gr...
