Detailed Description
In order to facilitate understanding for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples. The method comprises the following specific steps: implementation mode one
The method for knitting the seamless flat-inserted rib-stitch bag opening by the double-needle bed flat knitting machine is characterized in that a shirt piece, a bag sticker and a rib-stitch bag opening sticker are formed by one-time knitting, the bag is pasted on the bottom surface of the shirt piece, the rib-stitch bag opening sticker is pasted on the front surface of the shirt piece, and the following knitting procedures are carried out:
1. and (3) region setting, namely dividing the shirt piece into regions and dividing the positions where the bag sticker and the rib pocket mouth sticker are to be set, as shown in figure 2. In the figure, the ACDF area is of a double-layer structure, the CD is the opening part of the plain-insert pocket, and the front side of the BCDE is of a rib structure.
2. In order to achieve seamless knitting molding, 2 yarn guides are used for knitting in the a '-D' range, and one yarn guide is provided on the left side (not set to No. 1 for convenience of description) and the other is provided on the right side (not set to No. 4 for convenience of description). The face of the a → A, A → F site is knitted with the front needle bed of the No. 1 carrier, the bottom of the a → F site is knitted with the back needle bed of the No. 4 carrier, the F → F site is knitted with the front needle bed of the No. 4 carrier, the No. 1 carrier is knitted one course from left a' to right F, and then, one course is knitted one course from right F to left a ″, and so on; the No. 4 yarn carrier weaves a course from right F 'to left a, and then weaves a course from left a to right F', and so on; thus, the a 'B' BA region is knitted with the front needle bed by the No. 1 yarn guide, the ABEF region is knitted with the front needle bed (pocket front) by the No. 1 yarn guide, and the back needle bed (pocket bottom) is knitted by the No. 4 yarn guide, forming a double-layer structure, and the FEE 'F' region is knitted with the front needle bed by the No. 4 yarn guide.
3. And (3) when the yarn guide No. 1 is woven from the right F to the left, the front needle bed is hung, and when the yarn guide No. 4 is woven from the left A to the right, the front needle bed is hung, so that the circulation is performed, so that A 'B' BA and ABEF regions and ABEF and FEE 'F' regions are connected in an interlaced hanging manner, and the closure of AB, FE and shirt slices is ensured.
4, the front face of the BCDE area is of a rib structure and needs to be knitted on the front needle bed and the back needle bed, and the No. 4 yarn carrier is knitted by separating needles on the back needle bed and has a needle position, so that the loops of the front needle bed can be turned over to the needle position on the back needle bed by separating needles to knit the rib, and then the needle is moved back to the original position. The specific technical method of this embodiment is as follows:
4.1 before yarn finger No. 1 is knitted from left B 'to right E, stitches on the B → E site forward needle bed are turned over with needles to the empty needle site of the back needle bed, then, the B → B site is knitted by the yarn finger No. 1 forward needle bed, the B → E site is knitted by the yarn finger No. 1 on both the front and back needle beds (rib formation), and then, the yarn finger No. 1 is knitted again from E to left B', thereby circulating;
4.2 after the loops on the empty needle position of the back needle bed on which the B → E position front needle bed is turned over with alternate needles before the 4 th carrier is knitted from right E 'to left B are moved back to the original position, then the E → E position is knitted by the 4 th carrier front needle bed, the E → B position back needle bed is knitted with alternate needles, and then the 4 th carrier is knitted again from B to right E', and so on;
and 4.3B 'C' CB and BCDE regions and BCDE and EDD 'E' regions are connected in an interlaced hanging mode, so that the BC and the ED are closed with the shirt pieces. Thus, the B ' C ' CB region is knitted by the yarn guide No. 1, the BCDE region is knitted by both the front and rear needle beds of the yarn guide No. 1 (insert pocket face rib), the rear needle bed (insert pocket bottom surface) is knitted by the yarn guide No. 4, forming a double-layer structure, and the EDD ' E region is knitted by the yarn guide No. 4.
The CD part is a flat position of a pocket opening, cannot be connected with a shirt piece, and the front needle bed coil of the C → D part needs to be flatly closed, but the flat closing of the flat knitting machine is realized by the transfer of the coil on the front needle bed and the back needle bed and the transverse movement of the needle beds, and at this time, the knitting needle of the back needle bed is provided with the knitted coil, so the coil which influences the flat closing on the back needle bed needs to be transferred, and the needle position is vacated for the flat closing. In this embodiment, the split knitting of the pocket insertion at the C → D portion is realized by moving the needle bed stitches. The specific technical method of this embodiment is as follows:
5.1, integrally moving the coil on the front needle bed at the C → C position by a needle pitch to the left, and reserving a needle position for flat narrowing;
the No. 5.21 yarn guide weaves a coil from the left C to the right, and then the coil on the back needle bed corresponding to the coil moves left by a stitch pitch to turn over the needle to the empty needle position of the front needle bed; the No. 1 yarn guide kicks back leftwards, moves a newly knitted loop on the front needle bed to the rear needle bed (at the moment, the loop at the needle position of the rear needle bed is moved to the front needle bed), the needle bed moves transversely, and moves the loop to the right on an adjacent knitting, thereby completing the flat narrowing of the loop. (when the stitch on the back needle bed moves one stitch distance to the left to turn over to the empty needle position of the front needle bed, the direction of the No. 1 yarn guide must be right, otherwise, the part C → D will be connected with the shirt piece to form a closed opening). By this circulation, the front needle bed stitch at the C → D position can be folded flat. And flat narrowing of the screw thread bag opening is realized.
5.3 finally the left-shifted one-gauge stitch loop of the C → C region on the front needle bed is reset.
6. To realize the knitting operation in the flat knitting machine, the present embodiment (self-defines) the following code:
6.1 as shown in fig. 3, defining 120 as a 'B' BA region code, 121 as an a → B region-to-sequin engagement code, 122 as an ABEF region code, 123 as an F → E region-to-sequin engagement code, and 124 as an fe 'F' region code, wherein 215
6.2 in FIG. 5, the
6.3 as shown in FIG. 4, the code for the 128-B 'C' CB region is defined; 129 is a connection code of the B → C part and the shirt piece, and 130 is a BCDE area code; 131 is the connection code of the E → D part and the shirt piece. 132 is the EDD 'E' region code.
Setting the codes according to the step 6, and then preparing before weaving: the left yarn guide on the left guide rail of the flat knitting machine threads yarns, the right yarn guide on the right side threads yarns, and the colors of the yarns are the same. Then, fig. 3, 4 and 5 are specific weaving instructions in the custom code, and the custom code in the figures, including the functional lines, is all copied and pasted in the platemaking software. According to actual production, the size of each area of the product is determined, and the custom code is pasted in each area respectively, as shown in fig. 6. The row before the
