Abstract

The invention relates to the production of knitted fabrics of increased thickness, namely the multi-layered bases of knitted fabrics and allows for the expansion of the range. The outer and inner layers of multi-layer knitted fabric are connected by double bases of these weaves, of at least three threads, and the looped rows of cover-cross-weave alternately drawn to one another at certain intervals on both sides of the knitted fabric are interconnected along the outer a layer of knitwear with the coverslip thread, and the looped rows located between them are bent inward to form an internal filling. 2 sec. f-ly, 2 ill.

Description

The invention relates to the production of knitted fabrics of increased thickness.

The purpose of the invention is to expand the range.

FIG. 1 shows the structure of layered knitwear; in fig. 2 - a graphic record of the filaments in the case of multi-layered knitwear.

The proposed multi-layer knit (Fig. 1) contains outer layers I and II, double weaves 1 and connected by connecting elements III, forming the inner filling, consisting of looped columns, which are connected to one another with the formation of a single interlacing, the extreme loops of which 2 and 3 cc are in loops 4 and 5 of the opposite layers I and II. In order to reduce dissolvability, the outer layers I and II and connecting elements III

double bases are made with these interlacings 1 of at least three systems H, H and H, and they are made after a certain interval, on each side of knit I and II, looped rows of cover-throw weave with loops 4 and 6, 5 and 7, alternately attracted to one another (4 to 6 and b to 7), are interconnected along the outer layer of knitwear I or II with the covering thread 8 or 9, and located between the cover rows with loops 4 and The 5 looped rows with loops 2,3,10 are curved inward, forming the internal filling of the knitwear III.

The use in the outer and inner layers of the two-foundation foundations of knitted weaves that have a lower dissolvability reduces the dissolution of the multilayered foundations of knitted jersey as compared to the culinary ones.

Knitwear can be obtained on a double-base warp with a three-die gate machine and equipped with a mechanism for keeping old loops from lifting when being closed, for example, with platinum, as with modern Rachel machines. The sequence of formation of a series of layers and a joint is shown in FIG. 2 graphic records of the laying of threads. It is assumed that the needles are placed in the back of the head to each other and there are old loops on them. Comb IV, V and VI. First, there are rows of a cover-weave interlacing of the combs IV and V (Fig. 2A, 2B), where the comb IV is the cover coat and the comb V is unpaved for the front side of the knitwear. Comb VI thread on the needle does not lay and it comes in the form of a vertical thread.

Then the rows of double interlacing of the comb V (Fig. 2B, 2D) continue to be pressed, and the comb IV and VI are not laid on the needles. Thereafter, rows of cover-cross over weave from the combs V and VI (Fig. 2D, 2E), where comb VI is the cover coat and V comb, for the back side of the knitted fabric. Comb IV does not lay the thread on the needles and it goes in the form of a vertical thread. The process is then repeated (Fig. 2G-20).

In order to tighten one row of coverslip to another (Fig. 2I), it is necessary that the tension of the cover thread be greater than the tension of the soil thread and the pull-out force of the knitwear. Moreover, it can be constant or increase only at the moment of attracting one row of cover covers to another, i.e., at the moment in the next rows of rapport R with combs IV or VI. The thickness of the knitwear depends on the number of rows of main weaves connected between the two rapports of the cover weave formed by the threads of different combs IV and VI. The frequency of the binding elements depends on the number of rows of coverslip bound, connected without a perekidki in one repeat. The knitwear of the yarns may contain in the outer layers and connecting elements any single and double bases knotted, interlaced, be produced from several types of raw materials,

have any weft inserts in horizontal and vertical directions.

The connecting elements VI can be joined together with one another to form a single weave or consist of one or more looped columns that are not connected to each other.

For the outer layers and connecting elements, any number of filament systems of more than three can be used. The proposed multi-layer knitted knit is used in the manufacture of cloths of increased thickness for technical purposes.

The main object of the present invention is a material sewn from several knitted fabrics of limited thickness superimposed on one another. The proposed knitwear is more durable, does not dissolve when underlaying and does not stratify during operation, is less labor-intensive to manufacture, its cost is lower, and the consumption of raw materials per unit of production is less.

The method can be implemented on a double-foundation warping machine, which has three combs and is equipped with a mechanism for keeping old loops from rising when they are closed, for example, with platinum.

A method of making a multi-layered knitted jersey consists in that at certain intervals R (Fig. 2)} shifted by half the rapport R / 2 on both sides of the knitwear alternately in rows of cover-fold weave (Fig. 2A, 2B, 2D, 2B, 2K, 2K, 2H, 20), which pull one to the other (2B to 2I, 2E to 2H) along the outer side of the knitwear due to the fact that the tension of the thread of the covering combs IV and VI exceeds the tension of the soil comb V and strength jersey knitwear.

The method is carried out as follows.

All the needles are assumed to have old loops. The needle placement can be either interlock (Fig. 2) or elastic. Three combs IV, V, and U1 are used for the undercarriage; First, a series of cover-reversible weaves from combs IV and V (Fig. 2A, 2B), where comb IV is a cover coat, and

comb V dirt, for the front side of the knitwear. Comb VI thread on the needle does not lay, and it comes in the form of a vertical thread. Then the rows of double interlacing of the comb V (Fig. 23, 2D) continue to be pressed, and the comb IV and VI are not laid on the needles. After producing half of the rapport R, there are rows of cover-throw weaves made from the comb V and VI (fig.2D, 2E), where the comb V is soil and comb VI the cover for the back side of the knitwear. Comb IV does not thread the needle, and it goes in the form of a vertical thread. After this, the process in the underreport is repeated.

To push one row of coverswinding (Fig. 2B) to another (Figs. 2I), it is necessary that the tension of the cover thread is much greater than the tension of the soil thread and the knit strength. Moreover, it can be constant or increase only at the moment of attraction of one row of cover covers to another, i.e. before declaring row 2I for comb IV or row 2H for comb VI.
