Description

[Detailed Description of the Invention] A new method for obtaining a double knitted knitted fabric in which both knitted knitted fabrics without 2. The present invention relates to providing a knitting device.

Various methods of knitting double knitted fabric already exist, but a typical one is, for example, a method in which the front and back fabrics knitted using a plain knitted knitted fabric are partially joined together. Examples include a double-knitted fabric, or a double-knitted fabric with a double-sided stockinette structure. However, it is known that all of these double-knitted fabrics have problems in terms of heat retention and wearability.

Furthermore, knitted fabrics having through-holes are also known for knitted fabrics, but in the conventional method, upper and lower needles for fabric knitting that are common to both the upper and lower hooks are arranged, and upper needles and transfer jacks are respectively arranged on the upper hook side. In order to perform the knitting operation by storing the needles in separate needle grooves, the part with the through hole and the flat knit or rubber knit part iL3 are knitted continuously in the fail direction, and -1 stockinette with a coarse stitch density is knitted continuously in the fail direction. All you can get is the fabric.

The present invention has been made in order to solve the problems with conventional double knitted fabrics and the problems with transparent knitted fabrics. By feeding each yarn separately to the lower needles, knitting a stockinette fabric with through holes on the lower needle side and mrfting a stockinette fabric without holes on the upper needle side, the front and back knitted fabrics can be g-formed at the same time. When placing a transfer jack on the upper hook side to form a transparent hole in the knitted fabric by scooping up the sinker loop part of the lower needle side knitted fabric, the jack is placed together with the upper needle. By housing the needles together in the needle grooves, it is possible to have a pattern of transparent holes, and it is possible to easily obtain a transparent stockinette fabric with a fine stitch density, and the front and back knitted fabrics can be partially removed. By joining the two fabrics with a common binding thread, it is possible to easily obtain a double knitted fabric with excellent breathability, heat retention, and wearability. In a knitting machine consisting of a lower hook and an upper moss, each lower needle for knitting silk fabric, which has a through hole in the lower hook needle groove, is arranged so as to be freely raised and lowered via an elevating cam. The needle grooves are wide and narrow, and the narrow needle groove is used for knitting knitting needles that do not have through-holes, and the wide needle groove is used for transferring a pair of stitches that sandwich the upper needle and the lower needle. The jacks are arranged so as to be freely advanced and retracted via forward and backward cams, and yarn is fed to each of the upper and lower needles to knit the ring bullion, and the sinker loop portion of the knitted fabric on the lower needle side is formed by the transfer jack. The entire through-hole part is formed in the knitted fabric on the lower needle side by scooping it up, and the lower needle side knitted fabric and the knitted fabric on the lower needle side are partially bound together via a binding thread that is commonly supplied to both the upper and lower needles. By doing so, it is possible to obtain a double knitted fabric in which both the knitted fabric with through holes and the knitted fabric without through holes are integrated.

The present invention will be described in detail below with reference to the illustrated embodiments. Figures 1 to 5 show details of each embodiment of the upper needle, lower needle, and transfer jack used in the present invention.

Next, as shown in FIGS. 11 and 16 (5), the lower needle 111 (
21 becomes a cylinder 14 which rises to a tank position lower than the formation position and descends. This is to relax the transfer loop (al(a)) that is locked on the transfer jack (5a x 5b) to allow the next transfer operation to occur smoothly, and therefore to reduce the elasticity. If said loop (a) (a) has sufficient elasticity by using a rich braid,
Since it is not necessary to particularly perform the loosening operation of the loop (a), it is only necessary to perform this operation depending on the properties of the knitting yarn used, and only when the silk yarn is relatively stretchable and tough. Next, as shown in Figures @11 and 12, the transfer jacks (5a) (5b) were advanced by the extrusion cam.

The device of the present invention is not limited to the illustrated embodiment;
Modified embodiments are easily possible, in part due to various design changes. Some of them are described below. In the illustrated embodiment, the front and back fabrics (A

101), the subsequent knitting of the second course (2c) using the second yarn feeder (102), and the transfer operation of the transfer loop are shown in FIG. 11 described above. There are nine instructions. Next, on the lining (Bl side), although not shown, in the upper hook (8) shown in FIG.
), and then, as shown in the same figure, the second yarn feeder (202) knits the lining (the second course (2C) on the chain side), but the corresponding lower hook (7) is knitted.
On the side, as shown in Fig. 20, only the lower needle (2) is raised and lowered to the tuck knitting position by the select cam (+5) previously shown in Fig. 11, and at this time the upper hook (7) Tuck knitting is performed by supplying the second yarn (202) on the side as a binding yarn to the lower needle 12) side. Next, as shown in the figure, on the upper hook (81 side), the lower yarn feeder (203) and the fourth yarn feeder (204) are sequentially supplied to the upper needle +31 [41, and the third course (3c) on the lining fBl side is fed. , 4th course (4

Then, as shown in Fig. 20, the fourth yarn feeding (1o4) is performed on the lower hook (71 side),
The first course (4C) of the outer material (N) shown in the figure is knitted, and by this, the front and back fabrics (A) and (B) are partially bound by the binding loops latched to the outer material (2). is also easily possible.

It is also possible to form a knit loop (105b) as shown in the outer material (3) shown in FIG. 23 and use this as a binding loop. That is, in the case shown in Fig. 20, the lower hook (2) is raised to the tank knitting position by the select cam 71;

The apparatus of the present invention has the following excellent features as a device for obtaining a new double knitted fabric. In other words, it is possible to simultaneously knit the outer material (A), which has a patterned pattern by having through holes (A) and (B), and the lining material (B), which does not have perforations such as flat knitting, and also allows both the front and back surfaces to be knitted. Because it is a double knitted fabric that integrates (A) and (B) by partially binding, the fabric as a whole does not lose its flexibility and has excellent properties such as heat retention, moisture absorption, and water absorption. I will have it. At this time, when forming the through holes (a) and (b) between the fells by scooping out the sinker loop, it is necessary to arrange these through holes (a) and (b) in a pattern. In addition to giving the fabric a nice appearance, the negative side can be an uneven surface and the other side can be a smooth surface, and either of these can be used as a useful surface. At this time, the through holes (a), (b), and S are for the lining that does not have through holes (it is applied without penetrating the lining side, and the through hole 10)
The surrounding area of the outer material has a raised three-dimensional bulge due to the collection of sinker loops, which creates a heat-retaining space and is also advantageous for absorbing moisture and water. Furthermore, the fabric as a whole does not have the disadvantages of inhibiting elasticity or losing flexibility that are seen in conventional double knitted fabrics, and has appropriate flexibility and elasticity and shaping properties, so it does not lose its shape and can be used in various types. It has wide adaptability for use in clothing and underwear, and has the advantage that the length of the through hole can be formed as desired, and that any number of courses of the ground knit portion can be formed above and below the through hole. In particular, in the device of the present invention, by adopting a structure in which the knitting needles and the transfer jack are housed together in the needle groove, it is possible to eliminate the number of sets of stitch density and obtain knitted stockinette fabric with a dense structure. Moreover, the knitting process does not require any particular difficulty or complexity, and a relatively simple cam mechanism suffices, making it an excellent method for obtaining double knitted fabric with new characteristics. .
