Abstract

Usage: in the knitting industry with the knitting of high friction yarns. SUMMARY OF THE INVENTION: Rapport of weaving is formed in six hall systems. Loops are formed on the needles of the disk through one in all systems, on the rest - in five out of six systems. On the needles of the cylinder, they form loops and drafts through the system through one, on the remaining needles they form loops in two systems and drafts in four systems. 4 ill.

The invention relates to knitwear production, in particular to the production of double weaving press knitwear on a multi-system circular knitting machine, and can be used to increase the processability of knitting high friction yarns, as well as to increase the heat-protective properties of knitwear by increasing its bulk.

Closest to the technical nature is a method for knitting a double culinary press patterned knitwear by knitting loops of usual sizes on the needle of the disc and making larger loops and drafts on the needles of the cylinder.

The disadvantage of this method is that on the needle of the cylinder, in addition to the usual press loops with indices two and three, they knit jacquard loops, which, located next to the disk loops connected by a pull, worsen the conditions the yarn necessary to perform the operation of closing the loop of the disc from high friction yarns, since it is quite problematic to drag a portion of the yarn from the fully enclosed jacquard loop of the cylinder, and the consumption of yarn from an unbent yarn is very limited. In addition, the knitwear obtained on the basis of the described method is less voluminous, since the presence of elongated jacquard loops reduces the relief of the knit surface and reduces the number of air gaps in the knit. And also press loops of such knitwear have no more than three drafts.

The aim of the invention is to increase the reliability of the knitting process using high friction bulk yarns, as well as to increase the heat-shielding properties of the knit by increasing its bulk.

Fig. 1 is a graphical diagram of the yarn for double weaving press knitwear on a multi-system circular knitting machine.

A method of manufacturing a double cooler press jersey on a multi-system circular knitting machine includes knitting loops (Fig. 1) on the needles of both needle beds in the first 1 in the clamping system, in the second 11 system press drafts H are laid on the cylinder needles through one needle, a shift by one needle the pitch of the sketches H is carried out in the third III and fifth V in the sealing systems, in the fourth IV and sixth VI in the sealing systems, the threads are laid in the form of press skirts Н for all the needles of the cylinder, in the fifth V system the loops Г on the needle of the disk are knitted through one .

When using high friction yarns for knitting on circular knitting machines, as a rule, the operation of closing, pressing and dropping is disturbed. This is due to a change in the conditions for knitting the thread in the loops, and the usual adjustment of the parameters in the knitting does not completely eliminate the defects that arise, which allows us to conclude that it is necessary to create special techniques and methods for making such a knit.

Figures 2 and 3 show diagrams of the operation of closing old hinges and sketches, as well as incomplete closing of old loops on the needles of a double-loop circular stitching machine.

After the end of the previous loop formation cycle, on the needle (Fig. 2) of the Hi4 cylinder, the old loop TWS is looped and H is thrown onto the needle shaft, at this time, the Spd loop is closed on the needle And, while the formation of a part of the thread is pulled into the Spd loop from incompletely enclosed SNS loops on the cylinder needles (Fig. C) (for example, incomplete conclusion of the old SNS loops is performed on all needles of the cylinder in the second II system, on even needles in the third ill system, on odd ones in the fourth IV and sixth V systems) and from the outline of H (in the first I and fifth

In V systems, each cylinder needle has a sketch of Н, in the third III system, a sketch of Н on odd needles, in the fourth IV and sixth

VI systems - on even ones) allow to normalize the process in the knitting and obtain defect-free knitwear from high friction yarns.

At the same time, the calculation of the maximum allowable values of the height of the cylinder needles for incomplete conclusion and the size of the throat of the cylinder needles ensures the reliability of the knitting of press loops with four drafts. For the sake of elastic weaving, it is necessary to use threads or

5 yarns with a low friction coefficient, for example, wool or semi-woolen yarn.

Figure 4 shows a double cooler press jersey containing loops formed by alternating loops 1 of normal size and enlarged loops 2, as well as press loops 3 and 4, 3

5 bb, c-c, dd, dd, and press loops 3 and 4 are located only on the front side of the knitwear. The weave pattern consists of at least six loop stitches I, II; III, IV, Vn VI, the first row of which is formed

0 from loops 1 and press loops 3 with outline aa, the second row is formed by loops 1, outline aa and press loops 4 with four designs of different lengths bb, cc, dd and d- e, the third and fifth rows are formed

5 The positive effect of using this method in a double cooler press jersey is that when using high friction yarns on a multi-system circular knitting machine,

5 on the adjacent needle and hauling part of the thread from the loops on the needles that do not complete the closure, the tension of the thread in the loops is reduced before performing the closing operations on the needle of the disc, which allows defect-free knitting of such a knit. The use of press loops with four drafts alternating with press loops having one sketch causes an increase in volume and

5 heat-protective properties of knitwear from the named threads. Moreover, the use for knitting in the second and fifth loop-forming systems of chemical pneumo-textured yarns, in the rest - wool and semi-woolen yarn, as well as any other combinations of natural and synthetic yarns, allows to produce high-volume knitwear, without compromising consumer properties in comparison with products made from natural raw materials.
