RU2299283C1 - Method for producing of knitted fabric with relief effects and free of openwork holes - Google Patents

Abstract

FIELD: manufacture of knitted fabrics, in particular, flat mesh fabric.

SUBSTANCE: method involves forming closed transfer loop in course; on forming of the given course, knitting loops through up to closed transfer loop; laying transfer thread during back stroke of lock system; knitting-through remaining course loops in initial direction; overlapping openwork hole by closed transfer loop during transfer of next group. Method allows flat fabric to be produced, said fabric being characterized by relief structural effects and being formed from system of inclined loops provided according to repeat pattern and straight loops. There is no openwork hole at inclined loop and straight loop boundary site since it is overlapped by closed transfer loop.

EFFECT: increased efficiency of equipment for producing of flat fabric free of openwork hole.

Description

The invention relates to the technology of knitwear production, in particular to double weaving knitwear of openwork weaves.

Known double culinary knitwear with a relief structural effect, formed from a system of inclined loops made according to the report of the pattern, and straight loops, at the border of inclined and straight loops there is no openwork hole overlapped by a loop from the previous loop series. The standard technology for the production of patterned effect is presented in figure 1, requires several cycles of loop transfer.

Figure 1 presents the following conventions:

0 - shift of needle bar I2 to the zero position;

1 ← - shift of needle bar I2 to the left by one needle step;

2 → - shift of needle bar I2 to the right by two needle steps;

↓ - transfer of loops to the front needle bar I1;

↑ - transfer of loops to the rear needle bar I2;

ο - the loop is knitted, located on the needle;

• - the loop is not knitted, located on the needle;

⇒ is the direction of the formation of loops.

In figure 1. The following looping cycles are shown:

1) Knitting according to the report of the pattern of loops located on the needle boxes I1 and I2 ⇐.

2) Sewing according to the pattern with a loop "a" skipped. The loop stays on the needle untied ⇒.

3) Transfer the untied loop “a” from the rear needle bar I2 to the front needle bar I1.

4) The shift of the rear needle bar I2 by two needle steps to the right. Transfer the untied loop “a” from the front needle bar I1 to the rear needle bar I2.

5) The shift of the rear needle bar I2 one needle step to the left. Transferring stitches “b”, “c” according to the figure from the front needle bar I1 to the rear needle bar I2.

6) The shift of the needle bar I2 to the zero position. Transferring stitches “b”, “c” according to the figure from the rear needle bar I2 to the front needle bar I1.

7) Knitting according to the report of the pattern of loops located on the needle boxes I1 and I2 ⇐.

The shift is carried out by the rear needle bar. A report of the magnitude of the shift comes from the zero position of the needle bar. Loop transfer occurs after the needle bar shift.

The disadvantages of this method of producing knitwear with a relief effect without forming an openwork hole are that the method is complex, multi-cycle, the loop is pulled, thereby reducing equipment performance. The structure of the knitwear, taken as a prototype, is shown in figure 2. The figure shows: a - an elongated loop from the loop series, overlapping the openwork hole; b - an inclined loop; in - an inclined loop forming a structural pattern; d - direct loops of soil (background).

EFFECT: obtaining a new method for the production of knitwear with embossed effects without forming an openwork hole, which allows to simplify the production of knitwear and increase the productivity of equipment.

The technical result is achieved by the fact that the method of knitting a double knitwear with a relief structural effect, which consists in the fact that a closed sketch is formed in the previous stitch row, so that when this loop is formed, the stitches are knitted before the stitch, then the yarn is laid back sketch, after which the knitting of the remaining loops of the row in the original direction, and the openwork hole during the subsequent group transfer is closed with a closed sketch.

The production scheme of the proposed knitwear is presented in figure 3.

The production process consists of three rows of knitting 1, 2, 3 and two portable rows 1.1, 1.2, the second row of knitting is divided into three stages a, b, c.

In the first row, the thread is laid from left to right on the needles: 2 - the rear needle bar, 3, 5 - the front needle bar, 8 - the rear needle bar. In the second row: a - the thread is laid from right to left on the needle: 8 - the rear needle bar, 3, 5 - the front needle bar; b - the thread is laid from left to right on the needle of the 4 - rear needle bar; c - the thread is laid from right to left on the needle of the 2 - rear needle bar. Thus, a closed sketch is formed on the needle of the 4-posterior needle bed. In the third row, the thread is laid from left to right on the needles: 2 - the rear needle bar, 3, 5 - the front needle bar, 8 - the rear needle bar. Then comes the first portable row 1.1. In it, the rear needle bar is shifted to the left by one needle step, then the loops located on the needles 3, 5 of the front needle bar are transferred to the needles 6, 8 of the rear needle bar, respectively. In the second portable row 1.2, the rear needle bar is shifted to the zero position and the loops located on the needles 6, 8 - the rear needle bar are transferred to the needles 5, 7 - of the front needle bar.

The structure of this knitwear is presented in figure 4. The figure shows: a - a closed sketch overlapping an openwork hole; b - an inclined loop; in - an inclined loop forming a structural pattern; d - direct loops of soil (background).

Thus, the proposed method has a smaller number of loops transfer cycles, while transfers the loops do not stretch, which leads to an increase in equipment productivity.
