Problems solved by technology

[0003] 1. There is no interweaving point between warp and weft yarns like woven fabrics. Although they have better plane mechanical properties than woven fabrics, their mechanical properties in the vertical fabric direction are poor, and warp and weft yarns are prone to delamination when impacted Phenomenon
[0004] 2. The warp and weft yarns are easily drawn out from the knitted fabric
[0005] 3. Existing knitting machines and their warp and weft interlacing knitting technology can only interleave warp and weft yarns in layers in parallel, and do not have the function of interweaving warp and weft yarns

Embodiment Construction

[0035] refer to Figure 4 , Figure 5 with Image 6 , a novel biaxial weft knitted fabric structure of the present invention ( Figure 4 ), which consists of weft flat stitch 1, warp 2 and weft 3. The weft yarn 3 is located on the reverse side of the weft flat stitch ground weave 1 and interweaves with the warp yarn 2. The warp yarn 2 alternately appears on the front side 4 and the back side 5 of the sinker arc of the weft flat stitch every two courses, and is connected with the ground weave 1. This is a fabric structure composed of knitted fabrics and woven fabrics.

[0036] The present invention adopts special biaxial flat knitting warp and weft yarn feeding device ( Figure 5 ) to weave the above-mentioned novel biaxial knitted fabric, the weaving process is as follows Image 6 Shown:

[0037] 1. Initial position: eg Image 6 Shown in (1), the knitting needle 2 has just completed the knitting of the previous knitting process and is at the lowest position. This momen...

Abstract

A novel dual-axial filling knitted fabric, which is the combination of woven fabric and knitted fabric, is composed of basic stitch (weft flat stitch), warp and weft on the back of basic stitch. Saidwarp interwoven with weft is alternatively presented on front and back surfaces of weft flat loop arc at intervals of two loop columns. A special warp-weft feeder of flat knitting machine is used. Its advantages are not layer separation of warp and weft, and better drapability.

Description

1. Technical field: [0001] The invention belongs to the textile field and provides a novel biaxial weft-knitted fabric, a weaving method and a warp and weft yarn feeding device for a special flat knitting machine. 2. Background technology: [0002] Biaxially knitted fabric is a fabric structure in which warp and weft yarns are inserted into the weave of knitted loops, and is widely used as a reinforcement structure for composite materials. There are three representative biaxial knitting structures at present: the first is the biaxial warp knitted fabric knitted on a biaxial warp knitting machine, such as figure 1 shown. In the figure, 1 is the weave of warp flat stitches, 2 is warp-lining yarn, and 3 is weft-lining yarn. In this kind of fabric structure, in addition to the warp flat, other organizational structures such as braided chains can also be used. The second is a biaxial weft knitted fabric woven on a circular weft knitting machine, such as figure 2 shown. In t...
