This invention relates to a knitwear industry and relates to a method for making knitted velvet.

There is a known method of making knitted velvet, with a trombone on a two-fountain mantle, they are stuffed with a plush jersey, forming a soil on the first needle bed, and a second loop pile, and a knitted knit fabric is trimmed under the velvet by mowing pile loops, which are preliminarily lifted on a speeder. The times, how many times the pile is cut (as a rule, at least two cuttings) 1.

Multiple operations on and. Steril) with a pile reduces the performance of the method.

The purpose of the invention is to increase the productivity of the method by performing a high-quality shearing in one pass.

The goal is achieved by the fact that, when stitching knit knit knitting is done, a loop is drawn on the second needle bed with an additional thread that forms a single crosshair, which sticks the pile loops to the ground plane.

In this case, knitwear is supplied to the tensioning zone, ensuring sequential dissolution of the loops from the additional thread and release from it of the pile loops to be trimmed.

An additional thread is threaded with a curly satin from a thread with the lowest coefficient of friction and linear density.

Stable orientation of the looped pile ensures high quality of the haircut eliminates the operation of raising the pile with a special finish of the fabric and eliminates the presence of the cut loops of the pile on the fabric with a single pass cutting and, therefore, improves the quality of the fabric.

FIG. 1-7 shows block diagrams of variants of velvet nap knitted fabric; in fig. 8-14 - graphic records of the layouts of yarn variants of velvet-like knitted knitwear; in fig. 15 is a diagram of the process of cutting haired loops with simultaneous

the dissolution of additional W / S.

Of the figures, the following designations are accepted: A - first, B - second, C - third, D - fourth, D - pa, E - poles, loop-forming systems; ground thread 1, pile thread 2, additional 1 sewing 3, knife 4 with a spiral blade, underlay 5.

The pre-fabricated method of making velvet-like knitted fabric is carried out on an estimated 1X round dressing machines.

Examples of velvet-like knitwear are shown in FIG. 1-7 and.

FIG. 1 and 8 pile knit fabricated on two loop-forming systems A and B with elastic knitting. In the first system A, at the same time, the ground thread 1 and the pile thread 2 are threaded on all the needles of the first needle, and the pile needle 2 is laid as a draft on all the needles of the second needle bed. In the second system B, the second needle is added to all the needles. 3

FIG. 2 and 9, Zi 10 and 4 and 11 pile knit fabrication is made on a circular filling machine with three loop-forming systems A, B and B. In the elastic form (Fig. 2 and 9), the first A and the second B-loop-forming systems simultaneously smudge the ground with 1 and the pile 2 threads per the first needle bar through the needle is in a staggered manner, and the pile spike 2 is laid in the form of sketches only on the needles of the second needle bar through the needle. The third system B stitches the additional thread 3 on the same needles of the second needle bed as the pile thread 2.

In the weave of FIG. 3 and 10, the pile thread 2 is laid as a draft for all, the needles of the first and second needles in the first loop-forming system A, and the ground one-piece 1 is laid on all the needles of the second needle bed of the second loop-forming system. B. An additional thread 3 is bound on all the needles of the first needle bar of the third loop-forming system B.

In the interlock pattern in FIG. 4 and 11 in the first A and second B systems simultaneously thread the ground 1 and pile 2 threads on the first needle bed through the needle in a staggered order, and on the needles of the second needle No. 1, pile the threads

2 through the needle in a checkerboard pattern. Third System B Tires an Extra Thread

3 on all needles of the second needle case.

In elastic interlacing in FIG. 5 and 12, the pile thread 2 is laid in the form of tailings on the needles of the first needle bed through the needle in a checkerboard pattern in the first loop-forming system A. Ground wire 1 is drawn in a checkerboard pattern on the first needle bed through the needle in the second B and fourth D loop-forming systems. An additional thread 3 is stitched on the same needles of the second needle case, “along the pile thread 2.

In the interlock weave (Fig. 6 and 13), the pile thread 2 is laid out in the form of sketches on the needles of the first and second needle cases through the needle in a staggered order of the first A and fourth G of loop-forming systems. A ground thread is threaded through a needle in a staggered 31 order on the first needle of the second B and fifth D loop-forming systems. Additional thread 3 is stitched through a needle in a staggered order on the second needle bed of the third B and sixth E loop-forming systems. In la, stichny weave (Fig. 7 and 14), the first A and fourth G of the system lay a pile thread 2 on all the needles of the first and second needle cases. The second B and p ta D systems fasten a ground thread 1 on all the needles of the second needle bed. The third B and the pole E of the system conduct an additional thread 3 on the needles of the first needle bar through the needle in a checkerboard pattern. Thus, when nap knitted fabric type velvet on the proposed method rpyiiTOBoe canvas in zhut kulirnuyu satin or derived satin. The pile thread can be either laid in the form of a footer on all the needles of the first and second needle cases (Fig. 3 and 10) or through the needle of the first and through the needle of the second needle cases (Fig. 5, 12 and 6, 13), or carried out together with the ground one. thread on one of the needle cases on all the needles and at the same time laid in the form of sketches also on all the needles of the second needle bed (Fig. 1 and 8) or similarly, but through a needle (Fig. 2, 9 and 4, I). An additional thread is stitched with a kulir satin or a derivative satin, i.e., an easy-to-bead weave. The process of shearing the pile loops with simultaneous dissolution of the additional filament is carried out as follows. Before dressing the shearing machine, the knitted fabrics are stitched with an overlock stitch, with the result that the loop structure of the additional yarn is broken. When refueling with a shearing machine (Fig. 15), the web has a longitudinal tension. During the shearing, under the action of the longitudinal tension of the web in zone 5, the previous one and immediately adjacent to the shearing zone 4, the additional dissolution occurs. Noah 3 in the opposite direction to the web. As a result, the tufts 8 are aligned and released for direct shearing. The coupling of the shearing and dissolving rates of the additional yarn 3 is controlled by the tension of the web.

FIG. 14 The knowledge of velvet nap knitwear using the proposed method with a large number of systems is impractical because it reduces labor productivity. Example. This elastic nose in the center of the round-shaped two-bridge 48-system machine Multicommet 18 class. Polyamide textured elastic thread No. 300x2 is used as a ground yarn, No. 45 viscose thread is used as a pile thread, MOHoifflTb No. 300 polyamide thread is used as a pile yarn. shearing machine During the shearing, in the zone immediately adjacent to the strizhi zone, the additional thread, the loop structure of which is broken during sewing, is broken up under the action of longitudinal tension. Pile loops are spread out for shearing. The gap between the clipper table and the cutting element (knife) is 1.3 mm. Moreover, even when shearing in one pass, the fabric is of high quality. After strizhi, the cloth is subjected to decoction and then stabilization. as a pile thread, acetate threads, cotton can also be used; - yarn, etc. The high-shrinkage thread is used as a ground thread, i.e. polypropylene thread, polyester of high extensibility can also be used. The advantage of the proposed method is that it allows you to shorten the production process of pile knitwear by eliminating laborious opphias, as an additional finish to lift the pile and pre-cut. The method makes it possible to use limestone circular machiniples) with two needle beds with both elastic and interlocking needle placement without existing accessories. For shearing, blades are also used by well-known shear maplets without any of their mods.
