Problems solved by technology

[0006] At present, the preparation of tubular composite materials from warp-lined and weft-inlaid fabrics woven by flat knitting machines has the problems of material waste and uneven fabric structure due to cutting and splicing. Due to the limitations of the circular weft machine itself, the weft-inserted tubular fabric has the problem that the number of warp and weft yarns inserted is small and the thickness is thin
[0008] In order to solve at least one of the above-mentioned problems, the present invention improves the yarn feeding mechanism, the weaving mechanism and the transmission mechanism of the existing weft-knitting, warp-inserting and weft-inserting circular machine, so that it can weave a tubular fabric with two layers of warp yarns and three layers of weft yarns. Fabric, which solves the problem of weft-knitted warp-inserted weft-inserted tubular fabric with few layers of warp and weft yarns and thin thickness

Embodiment 1

[0061] A circular weft knitting machine for weft-knitting multi-layer warp-lined and weft-lined tubular fabrics, such as Figure 1-Figure 6 As shown, it includes a yarn feeding mechanism 1, a weaving mechanism 2, a pulling and winding mechanism 3, a transmission mechanism 4, a control mechanism 5, a frame 6, and auxiliary devices;

[0062] Yarn feeding mechanism 1: weaving yarn guide 1-1, rib front plating yarn guide 1-2, rib back plating yarn guide 1-3, the first set of weft insertion yarn guide 1-4, the second The first group of interlining weft yarn guides 1-5, the third group of weft interlining yarn guides 1-6, the first group of interlining warp yarn guide discs 1-7, the second group of interlining warp yarn guide discs 1-8, dial creel 1-9, intermediate creel 1-10, needle cylinder creel 1-11, dial yarn guide frame 1-12. The bobbins of the first group of inserted weft yarns 12, rib front plating 8 and their yarn guides 1-4, 1-2 are arranged sequentially on the cylinder c...

Embodiment 2

[0074] A kind of method utilizing the circular weft machine described in embodiment 1 to weave weft-knitted multi-layer warp-lined and weft-lined tubular fabrics, such as Figure 9 shown, including the following steps:

[0075] (1) Starting position: dial 2-1 and cylinder 2-2 have just completed the knitting process of the previous cycle, and dial needle 2-3 and cylinder needle 2-4 are at the innermost and lowest positions respectively ;

[0076] (2) Knitting back: the dial cam seat 2-5 and the needle cylinder cam seat 2-6 rotate synchronously, driving the dial cam and the needle cylinder cam to rotate synchronously, and the needle disc knitting needles 2-3 and the cylinder knitting needles 2-4 Under the action of the needle triangle on the dial and the needle cylinder, respectively, move from the initial position to the outermost and the highest position, the old loops on the dial knitting needles and cylinder knitting needles (old rib loops and plating yarns) Circle) 7-1',...

Embodiment 3

[0082] The weft-knitted multi-layer warp-lined and weft-lined tubular fabric prepared by a method of embodiment 2, such as Figure 8 to Figure 11 Shown:

[0083] The weft-knitted multi-layer warp-lined and weft-lined tubular fabric structure has a binding system of 1+1 rib weave 7, including rib front loops 7-1 and rib reverse loops 7-2, and rib front loops 7-1 and rib reverse loops. The stitches 7-2 are connected by adjacent rib stitch sinkers 7-7 of each course. Rib front plating 8 is lined in front of the rib front coil 7-1, the front of the fabric shows rib front plating 8, rib front plating sinker arc 8-3 connects two adjacent rib front coils 7-1; rib reverse plating 9 Lined into the back of the rib back stitch 7-2, the back of the fabric shows the rib back plating 9, and the rib back plating sinker arc 9-3 connects two adjacent rib back stitches 7-2. The first group of interlining warp yarns 10 is lined between two adjacent rib front coil posts 7-3, and the second grou...

The circular weft knitting machine comprises a yarn feeding mechanism, a knitting mechanism, a traction and winding mechanism, a transmission mechanism, a control mechanism, a rack and an auxiliary device, wherein the yarn feeding mechanism comprises yarn guides and creels of rib knitting yarns, rib front plaiting yarns, rib back plaiting yarns, a first group of weft insertion yarns, a second group of weft insertion yarns and a third group of weft insertion yarns, a first group of warp insertion yarn guide discs, a second group of warp insertion yarn guide discs and a warp insertion yarn creel; and the transmission mechanism comprises a main transmission shaft, a dial fixed shaft, a middle fixed shaft, a needle cylinder fixed shaft, a dial large gear, a dial fixed shaft sleeve, a middle fixed shaft sleeve, a needle cylinder fixed shaft sleeve, a main transmission shaft sleeve, a dial belt pulley, a middle belt pulley, a needle cylinder belt pulley and the like. According to the invention, the tubular fabric inserted with two layers of warp yarns and three layers of weft yarns can be woven, and the problems that the number of layers of the warp yarns and the weft yarns inserted in the weft-knitted warp-lined and weft-lined tubular fabric is small and the thickness is small are solved.

Description

technical field [0001] The invention relates to a weft-knitted multi-layer warp-inserted and weft-inserted tubular fabric, a weaving method and a special circular weft machine, belonging to the field of textiles. Background technique [0002] With the increasing demand for tubular composite materials with excellent extensibility in the industrial field, the weft-knitting and warp-inserting tubular composite materials have some excellent mechanical properties, such as impact resistance and energy absorption, which make the composite materials suitable for this industry. The research on quasi-tubular fabrics and their composites has been increasing and deepening gradually. The existing weft-knitted and warp-inserted tubular fabrics use plain stitches and ribs as the binding system, and monofilaments or multifilaments arranged in parallel are inserted in a specific direction to form a tubular prefabricated fabric with no curling and good formability. body. The tubular prefabr...
