Abstract

The invention discloses a weft-knitted multi-layer warp-inserted and weft-inserted tubular fabric as well as a knitting method and special circular weft knitting machine thereof, and belongs to the field of spinning. 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...
