Abstract

The solution is loop single warp knitted fabric of at least one yarn base system in the usual types of laying, from at least one loop system and at least one threading systems serving as temporary working means for shaping loops. The essence of the solution is that the 3-loops (5) of the knit are tied to the base a set of threads by blind laying in each or in any stitch column. The auxiliary system of threads is tied to the base a set of threads by blind laying or laying under the needles or joints with a basic set of threads at least in each second row to create loops (5) and any column of stitches or is longitudinally inserted.

Single-loop warp knit fabric

The subject of the jersey loop warp knitted fabric which is composed of at least one basic set of threads in conventional laying species, of _at least one loop set of threads and at least one auxiliary set of threads serving as temporary means for forming loops. The essence of the solution consists in that the knitting 3 loops (5) are bound in the basic set of threads by blind laying in each or in any stitch column. The ancillary yarn assembly is bound in the base yarn system by blindly laying or placing under the needles or common stitches with the base yarn system in at least every second row to form loops (5) and in any stitch columns or longitudinally inserted.

The invention relates to a loop single-warp knitted fabric, which in the basic embodiment consists of at least one basic set of yarns in direct, alternating or sequential laying, optionally in combination with laying under the needles. The effect component is at least one loop system of threads, firmly bound in the base system or base systems of threads. For forming the loops, at least one auxiliary yarn system with the possibility of forming common loops with at least one basic yarn system is used as part of the basic knitwear design.

Commonly known single-loop warp knits contain, in addition to the basic thread system, a so-called effect component in the form of a loop system of threads. They are made on single warp knitting machines equipped with some of the known types of knitting needles, but using plush sinkers. Loop warp knitted fabrics can be produced on hook or two-piece knitting needles without special equipment, but with constructionally modified discarded sinkers.

Also known from the patent literature and practice is a loop warp knitted fabric which uses an auxiliary assembly as a temporary work tool to allow loops by pulling loops from the fancy loop assembly away from the knit to one side or both sides, the loops are firmly bound by the basic set of threads and form common loops with it. In this case, the threads of the auxiliary system can form common stitches with the basic thread system in at least every second row, or they can be loosely inserted into the knitted fabric in the longitudinal direction. It is also possible to form loops from connecting loops or threads placed under needles of different width and / or height on one or both sides of the knit. The loop knits of this construction are particularly suitable for plain loop footage2

240 and higher weight, for example for thermal insulating inserts in garments.

It is an object of the present invention to achieve a lower weight of knitted fabrics at the same density as compared to known knitted fabrics comprising an auxiliary loop system for forming loops on warp knitting machines of conventional design. Another, no less important object of the invention is to create conditions for processing coarse-type yarns, such as tows, fancy yarns and the like, in a simple manner on fine-knitting machines under economically advantageous conditions and with the possibility of obtaining colored and plastic patterns from loops of different shapes. size and color.

To accomplish these objectives, a single-loop warp knitted fabric comprising at least one base yarn assembly, in addition to at least one loop yarn assembly, is firmly bound in the base yarn assembly. Another technologically necessary component consists of at least one auxiliary thread system serving for forming loops and with the possibility of forming common stitches with at least one basic thread system. SUMMARY OF THE INVENTION The loops are bound in the base thread system by blind laying in each row or in any rows and in each or any stitch column, and the subset is bound in the base thread system by blind laying, needle laying, common stitches a basic set of threads in at least every second row to form loops and arbitrary columns, or is inserted longitudinally.

It is also possible to shape the loops to different lengths. As far as the fabric composition of the knitted fabric is concerned, in addition to the smooth natural and chemical fibers, it is also possible to process coagulation materials into the used thread systems. Combination of loops with significantly coarse thread of the auxiliary system creates a plastic effect on the surface of the knitted fabric.

In addition to the above-mentioned advantages of the knitted fabric of the invention described in the stated objectives of its construction, ie saving material in the loop system item, achieving lower knitwear weight due to blind loop binding and manufacturing possibilities on commonly available machines, other advantages can be mentioned. This is an alternative alternating braiding of two auxiliary threads side by side for separate shaping

240 865 loops by pattern. Coarse yarns can be incorporated because they do not form stitches common to the base system, but are bound to the base system by blind laying.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in detail in the accompanying drawings of exemplary single-loop knitted weave embodiments, showing in FIG. a chain, a needle laying and a loop system with loops of equal height and width, in FIG. 3 two basic sets of yarns in a weave chain, a cloth and a loop set in a densified regularly spaced loop design and in FIG. loop system with one pitch offset.

In FIG. 1, the base of the knitting is formed by stitches 1 from a basic set of threads in a two-line atlas binding in which they are bound by blind laying of the loop 5. These are distributed between rows R2 to R4 to form loops 5 of different width. The yarns 6 of the sub-assembly are also tied in row R3 by blind laying, and the yarns 7 of the sub-assembly are tied in row R7 in a common stitch 1 * with the base yarn assembly.

Referring to FIG. 2, the loops of knitted warp knitting are formed by loops 2 in an open chain, which are interconnected by reciprocating laying 11 under the needles in a manner below three stitch pillars. Loops 5 of the same length and width are bound by blind laying in each row R1 to R4 and in each second / η of the stitch column to form a uniform loop cover. The yarns 8 of the sub-assembly are bound in the row R1 by laying under the needles in every second post and are longitudinally inserted in the remaining rows R2 to R4. The threads 9 of the sub-assembly are bound in the row R4 by laying under the needles also in every second post, while in the rows R1 to R3 they are longitudinally inserted.

FIG. 3 shows three rows of looped, one-face warp knitted fabric, the basis of which is the stitches 2 of the basic set of threads in an open chain together with the stitches 3 of the basic set of threads in a cloth weave. Loops 5 of the same height and width are bound by blind laying in each row in the base cloth weave

3, thereby being. the loops 5 are regularly distributed on the surface of the knit and form a high, dense loop cover. The yarns 10 of the sub-assembly are longitudinally inserted from both sides of the stitches 2 from the base system of threads in the open chain, and from both sides of the stitches 3 from the base system of threads in a weave.

Referring to FIG. 4, the loops of an open leotard form the basis of the looped one-stitch warp knits. The loops 5 are bound by blind laying in rows R1 to R3 alternately one above the other and in rows R4 to R7 offset one pitch alternately one above the other. The yarns 12 of the coarse assembly are interposed between the loops 5 and the loops 4 or their connecting loops from the base yarn assembly. In this case, the thread 12 of the auxiliary assembly helps to form the plastic pattern on the surface of the knitted fabric together with the loops 5 which surround it.

The knitted fabrics according to the invention can be applied in particular in the field of upholstery and home furnishings by virtue of the possibility of a wide range of blind-laying patterns,
