Abstract

FIELD: textile industry, in particular, manufacture of knitted fabric.

SUBSTANCE: weft-knitted fabric has open loops or closed loops, and is provided with additional coil in needle arcs of each loop. Additional coil is formed by winding of thread around needle during laying operation.

EFFECT: improved operating characteristics of knitted fabric, that is, reduced edge curling and filament relaxing.

Description

The invention relates to the technology of knitwear production.

Known weave smoothness - the most common single weave of knitwear, formed from the same shape and size of open loops, stretched one through the other in the same order, produced on knit-knitting single-loop machines [1].

The disadvantages of this interweaving are the curl from the edges of the knit, caused by the elasticity of the threads bent in the loops and tending to straighten, as well as the increased openness of the knit both in the direction of knitting and in the direction opposite to knitting, which leads to a certain difficulty when cutting and sewing.

The prior art is known for knitwear consisting of loops with open and closed loops and containing additional turns formed by wrapping needles with a thread (patent SU 55662, IPC D 04 B 1/00, 12/31/1939).

The technical result of the invention is to obtain improved performance properties of knitted fabrics.

The technical result is achieved in that the knitwear contains loops with open or closed loops, as well as additional turns formed by wrapping the needles with a thread during the laying operation, and the additional turn contains a needle arc of each loop.

The test samples have minimal twist. In the hinge column, the twist is practically absent due to the influence of the internal forces of the main loop and the turn with the opposite direction, which suppress each other and are expressed in the non-twist of the edges. In the hinge row, the curl is minimal from the wrong side to the face due to the closedness of the coil and its location in a perpendicular plane to the canvas. The forces concentrated in the coil to a lesser extent impede curl on the hinge column.

The loosening of the culinary weave with the turns is significantly less than that of the surface, since the presence of a turn causes additional contact points between the threads.

The invention is illustrated by drawings.

Figure 1 presents a diagram of a loop structure and a graphical record of weaving with open loops.

Figure 2 presents a diagram of the loop structure and a graphical record of weaving with closed loops.

For the drawings, the following designations are accepted: 12 - broach, 23 - loop stitch, 343 - turn, 35 - needle arc, 56 - loop stitch, 678 - broach, • - needle.

Cool knitwear was worked out at the stand of the Simak flat knitting machine.

During the closing operation, the needle rises. Next, the operation of laying the thread and the formation of a loop. At the first stage, upon receipt of open loops (FIG. 3a), the thread is laid over the back of the needle, and upon receipt of closed loops (FIG. 3b), the thread is laid on the needle. In the second stage (figure 4), the thread wraps around the needle, thereby forming a turn. In this case, the thread guide performs a complex movement: along the needle bar in front of and behind the needles, and also crosses the needle plane.

Thus, the proposed knitwear due to the presence in its loop structure of an additional turn has less curl from the edges and loose, which improves the operational properties of the knitted fabric.
