The invention aims to provide a weft-flat single-layer braided fabric warp-lining weft-lining braiding method, wherein warp yarns and weft yarns are lined in the single-layer braided fabric, and the structure of the single-layer braided fabric is reinforced.
In order to achieve the above purpose, the technical scheme of the invention is as follows:
the weft knitting method of weft-flat single-layer braided fabric warp lining weft lining comprises the following steps:
(1) Through the warp yarn guide, vertically feeding warps into the middle of the tooth openings of the front needle bed and the rear needle bed, and transversely arranging the warps among the tooth openings along a computerized flat knitting machine;
(2) The knitting machine head of the computerized flat knitting machine transversely moves into a knitting area, knitting yarns of a knitting yarn guide are fed into needle hooks of knitting needles which are fluctuated by a cam system on a front needle bed (also can be a rear needle bed, and are relatively required to be changed later if the rear needle bed is the rear needle bed), and knitting yarns form loops and withdraw the loops to generate knitted fabrics;
(3) Repeatedly executing the step (2), wherein knitting yarn guides on two sides of the warp are crossed (crossed, namely alternated, alternatively converted and used after one traversing knitting or after a plurality of traversing knitting, and the times are not limited), and the warp is lined in; each side of the warp (along the longitudinal direction of the computerized flat knitting machine) is provided with at least one knitting yarn guide, and if the same side is provided with a plurality of knitting yarn guides, the device can be used for using yarns with different colors, types and the like;
(4) After any one of the steps (2), weft insertion is performed:
(4.1) turning the loops of the knitted fabric on the front needle bed into the rest knitting needles at the corresponding positions of the rear needle bed with the spacing needles (one needle can be selected or a plurality of needles can be selected);
(4.2) transversely moving a knitting machine head of the computerized flat knitting machine into a knitting area, guiding the weft yarn on the weft yarn guide into the middle of the tooth openings of the front needle bed and the rear needle bed, and feeding knitting yarn on the other side of the warp yarn when the weft yarn is led in on one side of the warp yarn; thus, each side of the warp (along the longitudinal direction of the computerized flat knitting machine) is provided with at least one weft yarn guide, and if the same side is provided with a plurality of weft yarn guides, the warp yarn guide can be used for yarns with different colors, types and the like;
(4.3) the knitting machine head of the computerized flat knitting machine transversely moves, and the loops on the rear needle bed are turned back to the original needle positions of the front needle bed through the cam system, so that weft insertion is formed after the next transverse movement of the knitting machine head for knitting.
In order to improve the balance of the plane mechanical properties of the single-layer braided fabric, the previous weft is lined in the braiding area at one side of the warp, and the next weft is lined in the braiding area at the other side of the warp.
The method is simple, has low cost, and can insert warp and weft in the single-layer braided fabric to reduce the deformation of the fabric and strengthen the structure of the single-layer braided fabric. By selecting different warp and weft materials, the application field of the single-layer braided fabric is wider.

Detailed Description
A single layer braid (taking weft plain braid as an example) warp and weft lined braiding method:
(1) Through the warp yarn guide, the warp 6 is vertically fed into the middle of the tooth openings of the front needle bed 1 and the rear needle bed 1', and each warp 6 is transversely arranged between the tooth openings along the computerized flat knitting machine; the number of warp thread guides is plural, the specific number being based on the specific warp thread 6 requirements to be fed. The distance between the warp threads 6 in the vertical direction is also subject to specific requirements.
The computerized flat knitting machine adopted in the embodiment is provided with warp yarn guides 3 and 3', and the warp yarn guides 3 and 3' are positioned above the gaps between the front needle bed 1 and the back needle bed 1' of the computerized flat knitting machine. Along the longitudinal direction of the computerized flat knitting machine, one side (front needle bed side) of the warp yarn guides 3 and 3 'is provided with a weft yarn guide 4 and a knitting yarn guide 5, the knitting yarn guide 5 is positioned outside the weft yarn guide 4, and likewise, the other side (back needle bed side) of the warp yarn guides 3 and 3' is provided with a weft yarn guide 4', a knitting yarn guide 5', and the knitting yarn guide 5 'is positioned outside the weft yarn guide 4'.
(2) The knitting head of the computerized flat knitting machine transversely moves into a knitting area, knitting yarns of knitting yarn guides 5 and 5 'are fed into hooks of knitting needles 2 which are fluctuated by a cam system on a front needle bed 1, and the knitting yarns form loops and withdraw the loops to generate single-layer knitted fabrics 8 and 8'. Of course, the back needle bed 1 'may be used in this step, and the subsequent steps should be changed accordingly if the back needle bed 1' is used.
(3) Step (2) is repeatedly performed in which knitting yarn guides 5,5' on both sides of the warp yarn 6 on the computerized flat knitting machine are used alternately to insert the warp yarn 6, as shown in fig. 4. Each side of the warp 6 (along the longitudinal direction of the computerized flat knitting machine) is provided with at least one knitting yarn guide 3, and if the same side is provided with a plurality of knitting yarn guides 5, the device can be used for yarns with different colors, types and the like. The number of times after the cross, i.e., the alternate, transition may be after one traversing weave or after a plurality of traversing weaves is not limited, and generally, one traversing weave changes one yarn carrier (on different sides of warp).
(4) After any one of step (2), weft insertion is performed as shown in fig. 1-3:
(4.1) the stitches of the knitted fabric on the front needle bed 1 are turned over to rest needles at the corresponding positions of the rear needle bed 1'. The specific number of the separated needles is selected according to the requirement, for example, one needle can be separated, so that the loops on the 1 st, 3 rd, 5 th, 7 th and 9 th … … th odd numbered needles 2 on the front needle bed are turned into the back needle bed 1 'to rest the needles 2'. Of course, the needles may be separated from each other, and will not be described in detail.
