Abstract

The invention relates to the knitwear technology, in particular to the production of a two-layer knit fabric, and it allows to increase the productivity and improve the quality of the knitwear. The method of producing a two-layer knit jersey consists of laying synthetic thread on the needles of the cylinder with the formation of loops and on the needles of a disk with the formation of sketches, as well as laying the threads of natural raw materials on the needles of a disk. In this case, in some of the hall systems, the threads of natural raw materials are laid on the even needles of the disk, and in others in the hall systems, on the odd needles of the disk. The loop and sketch formed on the even needles of the disk are held without being bound for a certain time, and the loop and sketch on the odd needles of the disk are bound in the next working system. 1 hp f-ly, 1 ill.

Description

one

The invention relates to the technology of knitwear, namely, to the production of a two-layer knitted fabric, and can be used for knitting the knitted fabric for sports goods.

The purpose of the invention is to increase productivity and improve the quality of knitwear.

The drawing shows a graphical diagram of the laying of threads.

To implement the proposed method, multi-system circular machines are used, having the ability to switch the enclosing wedges in the cylinder and disc locks in at least three positions or with other needle selection mechanisms (drums, discs). By car you must have at least eight in the hall systems.

The proposed method is carried out as follows.

In the first one, in the behind - wall system, the first one is pushed on all the needles of the cylinder and an outline is drawn on the even needles of the disk. In the second, in the hall system, a second thread is stitched on the even needles of the disk, forming the loop of the derived surface. In the third system, the first thread is stitched on all the needles of the cylinder and form sketches again on the even needles of the disk. In the fourth, in the gate system, a second thread is bound on odd needles of a disk. The even needles of the disk are turned off from work, keeping the loop and the sketch formed on them in the second and third, respectively, in the hall systems. In the fifth, in the filing system, the first thread is stitched on all — the needles of the cylinder — and form sketches on the odd needles of the disk. The even needles of the disc continue to hold the loop and sketch. B sixth in the behind-the-door system, lead a second thread on the odd needles of the disk. In this case, the loops and sketches, formed in the fourth and fifth, respectively, in the hall systems, are dropped onto the surface derived loops. In the seventh, in the gate system, the first thread is bound in a manner similar to the fifth system. In the eighth in the hall system include

even needle discs, turned off in the fourth in the gate system, and tie a second thread onto them, which are looped and sketched by the second and third systems. As a result of such a long retention of the loop and the pattern on the needles of the disk, additional Q orientation of these elements of the looped structure of the knitted fabric along the hinge columns occurs, which increases the dimensional stability of the web in this direction. Increasing the dimensional stability by width g is not achieved by the sequential arrangement of the surface smoothing loops on the night - side of the knitwear. In addition, knitwear, obtained by the proposed method, has an increased porosity, which improves hygienic indicators, which are important indicators of the quality of dp sports products.

In comparison with the known method, the proposed method has a higher productivity, since for the formation of one row of knitwear two systems are required instead of three.
