Detailed Description
Single layer braided fabric (taking weft flat-woven fabric as an example) warp lining and weft lining weaving method:
(1) The warp yarns 6 are vertically fed into the middle of the tooth openings of the front needle bed 1 and the back needle bed 1' through a warp yarn guide, and all the warp yarns 6 are transversely arranged between the tooth openings along the computerized flat knitting machine; the number of the warp yarn carriers is a plurality, and the specific number is based on the requirement of the warp yarns 6 which need to be lined. The distance between every two vertical warps 6 is subject to specific requirements.
The computerized flat knitting machine adopted in the embodiment is provided with the 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. In the longitudinal direction of the computerized flat knitting machine, one side (front needle bed side) of the warp yarn carrier 3,3 'has a weft yarn carrier 4, one knitting yarn carrier 5, the knitting yarn carrier 5 is located outside the weft yarn carrier 4, and similarly, the other side (back needle bed side) of the warp yarn carrier 3,3' has a weft yarn carrier 4', one knitting yarn carrier 5', and the knitting yarn carrier 5 'is located outside the weft yarn carrier 4'.
(2) The knitting head of the computerized flat knitting machine transversely moves into a knitting area, knitting yarns of the knitting yarn carriers 5 and 5 'are fed into the hooks of knitting needles 2 which are fluctuated by a cam system on the front needle bed 1, and the knitting yarns are looped and looped to generate single-layer knitted fabrics 8 and 8'. Of course, the step may be the back needle bed 1', and if the step is the back needle bed 1', the subsequent steps may be changed accordingly.
(3) The step (2) is repeatedly performed in which the knitting yarn carriers 5,5' at both sides of the warp yarn 6 on the computerized flat knitting machine are used crosswise to insert the warp yarn 6 as shown in fig. 4. At least one knitting yarn carrier 3 is arranged on each side of the warp 6 (along the longitudinal direction of the computerized flat knitting machine), and if a plurality of knitting yarn carriers 5 are arranged on the same side, the knitting yarn carriers can be used for yarns with different colors, types and the like. The number of times of the alternate-over may be not limited after one traverse knitting or after a plurality of traverse knitting, and generally one traverse knitting is changed to one knitting yarn carrier (on different sides of the warp).
(4) After any step (2), weft insertion is performed, as shown in fig. 1-3:
(4.1) turning the loops of the knitted fabric on the front needle bed 1 into rest knitting needles at the corresponding positions of the back needle bed 1' by separating needles. The specific number of the separated needles is selected according to the requirement, for example, the separated needles can be selected, so that the No. 1, 3, 5, 7, 9 \8230onthe front needle bed, the No. 8230on the odd numbered knitting needle 2 and the loops on the back needle bed 1 'rest knitting needle 2' are turned over. And the needles can be separated in number, which is not described in detail.
(4.2) the knitting head of the computerized flat knitting machine moves laterally into the knitting zone to introduce the weft thread of the weft thread guide 4 into the middle of the needle bed gap of the front needle bed and the back needle bed, and when the weft thread 7 is introduced to the side of the front needle bed 1 of the warp thread 6, the knitting yarn is fed to the side of the back needle bed 1 'of the warp thread 6, that is, the knitting yarn is fed to the side of the back needle bed 1' of the warp thread 6, and the weft thread 7 is introduced to the side of the front needle bed of the warp thread 6, as shown in FIGS. 1 and 2. When the weft yarn 7 'is inserted into the back needle bed 1' side of the warp yarn 6, the knitting yarn is fed into the front needle bed 1 side of the warp yarn 6, as shown in FIG. 3. Each side of the warp 6 (along the longitudinal direction of the computerized flat knitting machine) is provided with at least one weft yarn carrier, and if the same side is provided with a plurality of weft yarn carriers, the warp yarn carrier can be used for yarns with different colors, types and the like. The former weft is inserted into the weaving area at one side of the warp, and the next weft is inserted into the weaving area at the other side of the warp.
(4.3) the knitting head of the computer flat knitting machine moves transversely, and the loop on the back needle bed 1' is turned back to the original needle position of the front needle bed 1 through a triangle system. Thus, after the next weaving by the weaving head moving transversely (i.e. performing step (2)), the weft insertion is formed, as shown in fig. 4.
The method mainly uses one needle bed (a front needle bed or a back needle bed) as a knitting needle bed to knit, and if the front needle bed and the back needle bed are respectively knitting needle beds and are used in a staggered mode, the knitting method can be used for knitting the weft plain double-sided knitted fabric.
The above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
