Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized by simultaneously knitting both a stockinette knitted fabric with through holes and a stockinette knitted fabric without through holes, and by partially joining the two knitted fabrics. The present invention relates to a new knitting device for obtaining an integrated double knitted fabric.

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. For example, a double knitted fabric with a double-sided stockinette structure, 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. Also, knitted fabrics with perforations are known for knitted fabrics, but in the conventional method, common upper and lower needles for knitting the fabric are arranged in both the upper and lower hooks, and upper needles and a transfer jack are arranged on the upper hook side. In order to perform the knitting operation while being housed in separate needle grooves, the portion with through holes and the plain knit or rubber knit portion are knitted continuously in the wale direction.
Only single-ply knitted fabrics with coarse stitch density can be obtained.

The present invention has been made in order to solve the problems with conventional double knitted fabrics as well as the problems with transparent knitted fabrics. By feeding each yarn to the lower needles separately, knitting a stockinette fabric having through holes on the lower needle side and knitting a stockinette fabric having no through holes on the upper needle side,
When placing a transfer jack on the upper hook side for knitting the front and back fabrics at the same time and scooping out the sinker loop portion of the fabric on the lower needle side to form a transparent hole in the fabric. By housing the jack in the needle groove together with the upper needle, it is possible to have a pattern of transparent holes, and a transparent knitted fabric with a fine stitch density can be easily obtained. By combining the front and back knitted fabrics with a common binding thread, the two knitted fabrics are integrated, resulting in a double knitted fabric with excellent breathability, heat retention, and wearability. Therefore, the feature is that in a knitting machine consisting of a lower hook and an upper hook, each needle groove arranged in a row in the lower hook has a through hole for knitting fabric. of and 1
Three lower needles with high butts for raising and lowering the stages are repeatedly arranged, and one lower needle has high butts for raising and lowering two stages (upper and lower), and the upper hook has a narrow needle groove and a wide needle groove. Needle grooves are arranged in alternating rows, and these needle grooves have one row of high butts for advancing and retracting for three upper needles that are used for knitting fabrics that do not have through holes and have one row of low butts for advancing and retracting. A jack for transferring a specific sinker loop in a knitted fabric having a hole formed by the lower needle is provided on both sides of the upper needle disposed in the wide needle groove. A set of two needles having a high butt for advancing and retracting in one stage are arranged together in the same needle groove on both sides of the same needle so as to be able to move forward and backward independently from the upper needle, and for each needle as above. In addition, the positions of the forward and backward high butts in the set of two transfer jacks are different, and on the lower hook side, facing the rotation direction of the lower hook, all the lower needles have through holes for performing the knitting operation. 1. The second upper and lower cams, the third and fourth upper and lower cams for performing the tuck knitting operation on all the lower needles, and the lower needles having two stages of upper and lower high butts for advancing and retreating, perform the tuck knitting operation. An operating cam is disposed in the order of a select cam for knitting, and a first cam is disposed on the upper hook side toward the rotation direction of the upper hook for causing all the upper needles to knit the fabric without through-holes. , a second advancing/retracting cam, a select cam for performing knitted fabric binding operation on the upper needle which has one stage of high butts for advancing/retracting corresponding to the select cam on the lower hook side, and a select cam for all the upper needles. 3rd and 4th advancing and retracting cams for performing the knitting operation of the knitted fabric; extrusion cams provided in two stages, front and rear, for operating a set of two transfer jacks arranged together with the upper needle in the wide needle groove; The purpose is to arrange the retraction cams in this order.

Next, as shown in FIG. 17, a third course 3c is knitted on the outer material A, and a connecting loop is formed in the third course by the tack knitting of the lower needle 2. Next, as shown in FIG. 4th to
Yarn feeding 104 is carried out to knit the fourth course 4c of the outer material A shown in FIG. It is also easily possible to perform tying.

It is also possible to form a knit loop 105b as shown in the outer material A shown in FIG. 23 and use this as a connecting loop.
That is, in the case illustrated in FIG. 20, instead of raising and lowering the lower needle 2 to the tack knitting position by the select cam of the lower hook 7,
As shown in Fig. 2, the front and back fabrics A and B are joined by using a select cam 15a having a cam slope capable of knitting operation and causing the lower needle 2 to perform the knitting operation. Needless to say, this is easily possible, and the partial joining means for the outer material A and the lining material B in the present invention is not limited to the illustrated example and can be freely designed.

Moreover, what is illustrated in FIG. 24 is both the upper and lower hooks 7, 8, that is, the upper needle 3,

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 shape by having through holes A and B, and the lining material B, which does not have through holes such as plain knitting, and to partially connect both the front and back materials A and B. Since it is a double-knitted fabric integrated by the fabric, the fabric as a whole does not lose its flexibility and has excellent properties such as heat retention, moisture absorption, and water absorption. At this time, when forming through holes A and B between the wales by scooping out sinker loops, these through holes A and B are arranged in a pattern to improve the appearance of the fabric. In addition, one surface can be an uneven surface and the other surface can be a smooth surface, and either of these can be used as a surface. At this time, the hole is
Part (b) is blocked without penetrating by the lining B side which does not have any through holes, and the peripheral part of the outer material surrounding the through holes (a) and (b) is a three-dimensional ridge raised by a collection of sinker loops. In addition to creating a heat-retaining space, it is also advantageous in absorbing moisture and water. Furthermore, the fabric as a whole does not suffer from drawbacks such as inhibition of elasticity or loss of flexibility seen in conventional double knitted fabrics, and does not lose its shape due to its appropriate flexibility and elasticity and shapeability. , various clothing,
It has wide adaptability for underwear applications,
The length of the through hole can be formed arbitrarily, and there is also an advantage that an arbitrary number of courses of ground knit portions 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, coarsening of the stitch density can be eliminated and knitted stockinette fabric with a dense structure can be obtained. Moreover, the knitting work does not require any particular difficulty or complexity, and a relatively simple cam mechanism is sufficient, making it an excellent method for obtaining double knitted fabric with new characteristics.
