Description

Special flat knitting machine yarn feeding device for biaxially reinforced weft knitting spacer knitting structure

technical field

The utility model belongs to the field of textiles, and in particular relates to a novel yarn feeding device for flat knitting machines special for biaxially reinforced weft knitting interval knitting structures.

Background technique

The flat knitting machine is a flat weft knitting machine, mainly used for knitting woolen sweaters. In addition to the knitting yarn guide, the yarn feeding device on the flat knitting machine can also be configured to weave the warp and weft yarns of the biaxial weft knitting structure. device. Fig. 1 and Fig. 2 show two kinds of existing multilayer warp and weft yarn feeding devices, they comprise two groups of warp yarn guides and three weft yarn guides, wherein the positions of two groups of warp yarn guides are fixed, respectively The two sets of warp yarns are fed into the knitting area from the warp direction, and the three weft yarn guides reciprocate along the needle bed to feed the weft yarns into the needle backs of the weaving area from the weft direction, and the fed weft yarns are respectively located on the two sides and the middle of the two sets of warp yarns . The two devices shown in Figures 1 and 2 differ in the configuration of the knitting yarn guides. The device shown in Figure 1 has only one knitting yarn guide, which is located in the middle of two groups of warp yarns, and knitting yarns are simultaneously placed on the front and rear needle beds to weave a multi-layer biaxial weft knitting structure connected by rib weaves; and as shown in Figure 2 The device has two knitting yarn guides, which are respectively located on the two sides of two sets of warp yarns. The two knitting yarn guides alternately lay yarn on the front and rear needle beds to knit multi-layer biaxial weft knitting with two single jersey weaves connected. structure. Figure 2 shows the situation when the front needle bed is knitting, and the knitting yarn is placed in front of the knitting needles of the front needle bed.

Both warp and weft feeding devices can form up to three layers of weft yarns, and multi-layer biaxial weft knitting structures with two layers of warp yarns can be used as reinforcement structures for sheet-like composites. However, they can only form a planar structure with a certain thickness, and the thickness is limited by the yarn fineness and the number of layers, and cannot be flexibly changed in the third dimension to form a true three-dimensional spaced reinforced structure.
