Description

This invention relates to knitwear technology and relates to a two-ply knitted knit fabric and a method for its production on a double-support in a filling machine. Numerous versions of a double-layer knit jersey are known, containing in each layer a series of different single weaves, for example, smoothing or smoothing, joined by means of connecting elements, for example, loops, overlap of the stitches from the main or additional threads tli. In order to increase the thickness of these types of knitwear, it is necessary to increase the processing of the threads for the binding elements. . The closest to the invention is a knit fabric containing in each layer a row of single weaves, connected by means of connecting elements-sketches lying on the spans of the joined rows of one and another layer. The thickness of such knitwear depends on the length of the stitches connecting the sketches, and can be relatively large, but it depends on the distance between the needles, the depth of stitching of the sketches with the needles of two needles, which are caused by the design features of the machine. In addition, while simultaneously stitching enlarged binding elements of this type, it is possible to pinch the thread, which also limits the length of the stitch between the sketches, and hence the thickness of the knitwear. A known method for producing a two-layer knit jersey on a double-bottom in a zalinny machine, which in the needle cases of the machine, have layers in the form of single webs, which, according to a predetermined repeat, are connected by connecting threads. The aim of the invention is to increase the volume of knitwear and to create a method for obtaining a new weave structure. The goal is achieved by the fact that in a two-layer knit knit, each layer of which is made of a single weave, and the layers are interconnected by connecting elements, each. the binding element is a looped column, the first loop of which is in the loop of one layer, and the last loop in the loop of another layer, with the looped columns located between the layers connected to each other and form a single single weave. According to the method of manufacturing double-layered knit knitwear on a double-bottom in a filling machine, in which at its needle beds there are layers in the form of single canvases that, according to a predetermined rapport, are connected with connecting threads, after producing a predetermined number of looped p The single needles turn off the needles of the first needle bar without resetting the loops, and at least on each second needle of the second needle bar there is a single interlacing of knitting yarns, the loops of the last row of which are transferred onto the part of the needles of the first needle bar and extend them together with the old loops unary webs, after which single webs are again crooked and, similarly, for a given rapport, single weaving on the needles of the first needle case or again on the needles of the second needle bed. To obtain knitwear of any thickness, up to the present time, as a rule, stitching of cloths superimposed on each other is used, which complicates the technological process and increases the cost of the material. The proposed method allows to obtain a knitwear of increased volume by increasing the thickness of the web, regardless of the density of the layers. and parameters in the boom, without stitching is dense. Figure 1 shows the structure of the double-layer knitwear; in Fig. 2, a graphical record of the stitch of yarns in the knitwear, in which the layers are made by interlacing the surface; Fig. 26 is a graphical record of the clutches of threads when they are understated, in which layers are made by interlacing the surface; Fig. 3 is a graphical record of the stitch of the yarn when knitting is used, in the process of transferring the loops of which the needle case shift is used. The proposed double layer knit knit (Fig. 1) contains in each layer 1 and II, pores 1 and 2 of single weaves, connected by means of connecting elements. Its difference from the known one is that in order to increase the volume by obtaining any thickness of the web, each connecting element is a hinge column 3 and 4 located in a plane perpendicular to the plane of the hinge rows 1 and 2 of the connection e} f1x interlacing, with at least each second loop 5 and 6 of the connected row 1 and 2 of one single interlacing being the first loop of the tie column 3 and, 4 loops 7 and 8, the last of which are fixed in the joined row 1 and 2 opposite single This interlacing is arranged in the form of a sketch on the bars 9 and 10 of loops 11 and 12 of this row. On dvuhfonturnyh machines with platini, producing concentrated loops hinge, the number of rows of the connection of the dineni can be arbitrary, which allows to obtain knitwear of any thickness. In order to manufacture the proposed knitwear, the machine must have mechanisms for transferring the loops from the needles of one needle bed to the needles of another needle bed. The more columns 3 and 4 are located along the length of the knit, the greater the filling and thickness of the knit. The proposed knitwear may contain any single weaves in the layers, it may be produced from two or three types of raw materials — one for the Front layer, the other for the nanoscale, and the third for the connection stub. The sequence of the formation of a series of layers and joints is shown in Fig. 2 by graphical records of the positions of the yarns. When used for strand interlacing layers (Fig. 2a), rows are formed in the following sequence. After working for several rows of ironing, the needles of the front and rear needle beds (1 and P) are joined in rows of joints, for example, on the even needles of the front needle bed (W, IV, Y). The odd needles of the front needle case hold layers of the loop. New loops of the rows of the compound are carried out with platinum. . The loops of the last row of connections are transferred to even, for example, needles of the back needle bar (U1). Then there are several rows of ironing on the needles of the back needle bed (UE, yiTl). . Then, in the loop, the stitches of the incomplete weave on the odd needles of the back needle bar {IX,), XI) This is followed by transferring the loops of the last row of the knit to the odd needles of the front needle bed (XII) and finding several rows of the iron on all the needles of the front needle bed { Xlil, X1U). Then the cycle repeats. When used for interlacing layers, the derived smooth lines of a row are formed in the following sequence (Fig. 26). After producing several rows of the derivative of the smoothing or smoothing at both needle cases (1, P, there are a number of derived smoothing, for example, on the needles of the back needle bed (MZ then they produce rows of connection loops by incomplete weaving, for example, on the odd needles of the back needle bed (Y, U1 , UE). The loops of the last row of the compound are transferred to the odd needles of the front needle bed (UGP). After that, there are a number of rows of the derivative of the ironing needle with the needles of the front hospital (IX, X) and turn the rows of loops of the joint by incomplete weaving on even needles front yoke Flax (XI, XII, Xffl). Then the loops of the last row of connection are transferred to the even needles of the back needle bed (H1U). The cycle is then repeated. This is possible because the needles of the two needle cases do not work together. Other examples of the use of the proposed knitwear are possible. The field of application of this product is made of multi-layer knitted fabrics of increased thickness and detail. such products associated with the contour, frame paintings for technical products and special purposes. The proposed method can be implemented on a flat-flank machine, as well as on dvuhfonturny maishnah, which are equipped with platinum, producing concentrated loops. i A method of manufacturing a two-layer kulir (Fig. 3) knitwear on a flat-footed machine consists of removing single webs on all the needles of opposite needle cases. To connect the single webs, the connecting elements in the form of hinge bars on the odd needles 1 of one needle bar are wound up. After receiving the connecting elements, a shift of one needle relative to the other, for example, two needle steps, and a loop of columns from odd needles 1 of one needle bed to even needles 2 of the opposite needle bed are made. After transferring the hinge columns, one hinge row of the ironing is produced on the needles of both needle beds. Then the process in the underside of the connecting elements is performed on the even needles of the opposite needle bed, followed by their transfer to the odd needles of the other needle bed, and shifting it in the direction opposite to the first shift. After this, a looped stitching on all the needles of both needle beds is lived. P p i. m er Starting, for example, starting with the first row and eraser on all the needles of both needle beds. At the same time receive the earned edge of jersey. But in this case, the thickness of the knitwear of the beginning row is limited by the length of the needle between the needles of the front 3 and the back 4 needles. The second row of knitted fabric, for example, on the front needle bed 3 through the needle on the odd needles 1. The loops with the even needles off 2 are not dropped and left on the needles. The third and subsequent rows are the same as the second. The number of these rows determines the height of the hinge post, the connecting element, and, consequently, the thickness of the knitwear. After knitting, for example, four rows of stitches, the loop is transferred from odd needles 1 to the needles of the opposite needle bed 4 through the needle. To get shape-resistant knitwear, it is better to transfer the loops not to the opposite needle of the back needle needle 4, but to the second or TT ) this needle. Therefore, before transferring the loops, it is necessary to perform an ad-move of the back needle bed by 2-3 needle steps. Gyestoy p d zhut on all the needles of the back and front needle beds. The seventh, eighth, ninth and tenth rows in the quill needles 2 of the rear needle case. 4. After this, the front needle case 3 is moved by 2-3 needle steps and the loops are transferred from the even needles of the rear needle case 4 to the odd needles of the front needle case. 3. The eleventh series in all needles of the front and rear needle beds. The looping process is then repeated. It is not excluded the possibility of a knuckle-knitting boom only on the needles of one needle bed of the machine.
