Single warp knitted fabric with small plastic and openwork pattern

The knitting fabric consists of a base and a carrier bulging component in the form of embedded length fabrics, wherein all or selected columns comprise, in common eyes, the basic components of the stitches of direct laying. The stitching loops fax the embedded length fabrics of the backing component, for example, cross weft yarns, longitudinal weft yarns or threads placed under the needles alone or together with the stitch loops, at least one other yarn set. The inserted threads may be patterned in the transverse and / or longitudinal direction of the knitted fabric.

The invention relates to a single-faced warp knitted fabric

plastic and openwork pattern. The basic component of this knitted fabric is formed, for example, in a double combined warp weave from two sets of threads, the filling component being incorporated in the form of transverse or longitudinal threads, laying under needles and the like.

The construction of known single-faced warp knits with a plastic and openwork pattern is in most cases based on the principle of forming fillet or openwork weaves and patterns or combinations thereof. For example, in a tricot fillet weave, two and two columns are always contracted by counter-directionally laying two warps with a 1: 1 thread distribution, the size of the opening thus obtained being determined by the number of rows in the staple followed by transition to sequential or cloth laying. The position of the holes depends on the offset size. A similar effect can be achieved by binding using a two-eyed chain, ie from direct laying. The connection in a coherent whole - and thus also the pattern - is possible by offsetting the selected laying over several rows of knitting, thereby creating tiny holes in the weave between the two posts. In a filet cloth weave, the two and two columns are contracted by counter-directionally laying the two warps while splitting the threads 1: 1 that lay the cloth. The resulting holes between the pairs of posts are offset by one loop in the next row. They are based on a similar principle as well

- 2 260 696 atlases, jacquard or tigers with openwork pattern. These types of weaves are suitable for use in the fashion and laundry sector, or after further chemical or thermal treatment, also in the field of technical textiles, due to the use of their characteristic properties, such as airiness, drape, suppleness, color patterns and combinations and the like.

The object of the invention is simple weave structures of monolithic warp knitted fabrics, suitable especially for knitted fabrics for technical purposes, for example for shoe uppers, furniture upholstery, but also for outerwear with limited ductility in all directions and high strength based on chosen base weave in combination and by fixing length fabrics such as yarns, silk, spun yarns, tows, spun bundles. At the same time, the possibility of deleting the subsequent treatment procedures required to achieve this is monitored

Λ desired parameters of the final product. The stated objectives have been achieved according to the invention by the construction of a single-faced warp knit comprising essentially basic and padding components, whereby mainly the double combined warp knitting is applied in the basic component. The principle of the invention consists in that all or selected, for example every second or third column, comprise in the basic component so-called common stitches, composed of at least two partial stitches, at least one of which is formed by direct laying. In this connection, the stitch connecting loops of the stitching hold the inserted length fabrics in particular in the form of transverse or longitudinal weft yarns or laying under the needles, alone or together with the stitching loops of the other knitting element stitches. By this design arrangement, particularly favorable parameters have been achieved for the use of knitted fabrics in other, not yet considered regions, with the possibility of exemplary placement of the inserted lengthwise fabrics in the transverse or longitudinal direction. In addition to the advantages mentioned above, the use of direct laying results in a total reinforcement of the base fabric component and a reliable fastening of the inserted padding components to its ruben

260 698 side. The return loops, together with the direct loops, limit the ductility of the knitted fabric in all directions. The established transverse weft and prolonged placement under the needles or between the posts of the stitches ensure high strength and fullness of the knit. The plastic effect can be emphasized on both sides of the knitted surface by passing a longitudinal weft into the holes of the base component. The reverse side of the knitted fabric is suitable for surface treatment, for example, for combing, due to the substantially longitudinal orientation of the direct laying loops and their position across the inserted lengths. To increase bulkiness and patterning, the reverse side can be provided with a loop effect for improved properties. To achieve the desired physiological properties, a combination of natural and synthetic fiber materials with the possibility of regulating the efficiency of heat and moisture conduction is suitable. The use of knitted fabrics for shoe uppers, in particular sports shoes, is justified by the fact that only one knitted fabric according to the invention can be used in place of two separate, prior to the glued fabric layers, the mechanically produced connecting loops replace the gluing technology, i.e. In particular, the face side of the knitted fabric can be advantageously used as a substrate for printing, for example by transfer printing, which in this embodiment is emphasized by a small openwork and / or plastic pattern of the knitted fabric.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 illustrates the construction of knitting with common stitches from a basic set of threads and direct laying in all stitch columns with longitudinal weft threads inserted under the needles, FIG. 2 another variant with common stitches the stitches from the base system and from the direct laying in every second stitch pillar with the cross weft threads inserted, and in Fig. 3 a longitudinal section of the knitted fabric with the cross weft bundles inserted and the longitudinal weft inserted. FIG. 1 shows one possible embodiment

- 4 single-faced warp knits with a small plastic and openwork pattern, the basic component of which is made up of common stitches 4 »containing a stitching eye 2 ^{2 of} direct laying and a stitching eye 2 * of the base system. The needle arcs of the stitches 4 approach each other with their needle arcs in each other row, forming a tiny openwork and plastically protruding pattern. The direct loops of the stitching eyes 3 hold the threads 5 laid under the needles in the sleeve 1: 1 under the four needles alternately to the left and right in each row of threads 5. Reinforcement of the knitted fabric in the longitudinal direction is provided by inserting the longitudinal weft threads 9 into each second stitch column in the space between the common stitches 1 and the threads 5 laid under the needles. Referring to FIG. 2, the one-face warp knitting in each second, for example even, pillar, consists of common stitches 1 comprising a stitching ring 2 and a stitching ring 2 from one base assembly in a weave of the underlying cloth. All remaining odd knitted columns contain EJ stitches from two other jointly guided base threads, also in a weave cloth, laid in opposite direction to the common stitches JL · The stitch curls of stitches 1 and 8 approach each other with offset stitches . _f at the points of reversal of the laying of the underlying cloth. Each line of knitting interleaves one transverse weft yarn 4, secured against displacement or withdrawal by the connecting loops 3, the stitches 2 from the direct laying, and also by the connecting loops 6 of the stitches 2 of the base assembly and the double connecting loops 7 of the two basic threads. The longitudinal section through a variation of the one-piece knitted fabric according to FIG. 3 shows the possibility of further enhancing the usability of the knitted fabric by using a fiber bundle in the form of transverse weft yarns 4 bound by connecting loops 3, stitching stitches 2. 1, which are shown in the view of FIG. 1 in all the columns and rows of the knitted fabric. The inserted longitudinal weft yarns 9 reinforce the knitted fabric in the longitudinal direction.
