Problems solved by technology

[0005] Although stitch-bonded products have good application prospects in the industry, the traditional stitch-bonded method has the disadvantages of complex and expensive stitch-bonded machines, large investment, and long production process of stitch-bonded products because it is an array weaving method.
Because the existing stitch-bonded fabric is made on a specially designed stitch-bonding machine similar to a warp-knitting machine, its common features mainly contain the following two points: the one is integral, that is, all seam-forming parts, including The movement of needles and guide needles is centralized, just like the movement of warp knitting machines, which makes sewing machines generally specially designed equipment, which is more complicated and expensive; second, the sewing yarns are arranged in parallel, so the number of ends Generally more, and can only be woven on the machine after the warping process, the whole manufacturing process is long, the investment is large, and the production cycle is long

Embodiment Construction

[0011] The present invention weaves the specific implementation mode and the steps of double-sided stitching on weft knitting machine as follows:

[0012] figure 1 It shows the principle diagram of weft knitting and double-sided stitch knitting of the embodiment of the present invention.

[0013] On the flat knitting machine, the stitch-bonded core layer 1 is placed in front of the needle bed 3 in such a way that the knitting needles 2 of the front and rear needle beds do not traverse laterally. All the knitting needles 2 slide up and down in the needle grooves of the respective needle beds 3 sequentially according to the weft knitting mode to complete the knitting process. In the de-knitting stage of the knitting process (figure a, b, c), the respective knitting needles 2 of the front and rear needle beds rise and penetrate through the stitched core layer 1; then the weft yarn 4 (sewing yarn) is sequentially fed The back knitting needle 2 begins to descend again, and at thi...

Abstract

A method for weaving double-sided stitch-bonded fabric on weft knitting machine includes feeding core layer to be stitch-bonded between two needle bed tooth mouths in not left-right moving mode, rising and punching core layer to be stitch-bonded needle bed in clearing stage of stitching course then feeding a stitch-bonding yarn to each own needle bed according to weft-knitting mode, closing latch of each own needle bed by two latch closers separately when two needle needs are lowered down separately, hooking each own stitch-bonding yarn in cross way over core layer to the lowest position for finishing stitching course of double-sided stitch-boned fabric.

Description

Technical field [0001] The invention relates to a stitch-knitting manufacturing method, in particular to a method for weaving double-sided stitch-knitted fabrics on a weft-knitting machine. Background technique [0002] The existing stitch-bonding method originated in Germany, and its main method is to use yarn as stitching yarn to warp-weave and reinforce the fiber web as the core layer, making it a non-woven fabric similar to woven or knitted fabrics. . Since it has warp yarns, and the arrangement, material and linear density of warp yarns can be changed according to different requirements of the product, the strength of stitch-bonded nonwovens is greatly improved, and its application range is also expanded. Combined with appropriate post-finishing process, it can be made into various products for different purposes, which can not only partially replace woven fabrics and knitted fabrics, but also have the application performance of other non-woven fabrics. At the same ti...
