The invention relates to the technology of knitwear production. The technical result - the creation of the surface of the new textured effect in the form of embossed stripes of alternating in the direction of the bending arcs, while maintaining the shape of the canvas. Double weft knitted openwork weave contains two hinge layer formed by interweaving the surface. Each second hinge bottom hinge layer is stretched at the same time through the loops of his and upper layers, as in the direction of the hinge line, and looped pile. 2 Il.

The invention relates to weft knitting the knits and can be used in the manufacture verhnenemetskih products.

Known weft knitted fabric weave duchesnea surface formed from loops, stretched one over another so that the front and back stitch the rows alternate [1].

On the surface of both sides of this knitted fabric is formed original textured effect in the form of a horizontal embossed stripes of alternating the direction of bending of the needle and the platinum arc. This effect is produced due to the fact that due to the elastic force of the thread, curved in a loop, tenovyh arcs loop sling sticks.

The disadvantage of this structure is the low dimensional stability of knitted fabrics, which limits its use in the production of knitwear.

Double weft knitted openwork weave, two hinge layer which is formed by interweaving the surface, and some loops of one (lower) hinge layer is stretched at the same time through the loop as their own, and the adjacent (upper) hinge layers [2].

The method of obtaining such a Jersey is to separate the knitting stitch layers on two igalnice weft knitting machine with a periodic transfer of the loops from one (front) needle cases on the other (rear).

On the surface of the front hinge layer of such a Jersey (wywiazywania on the front yalniz) is formed textured effect in the form of blind tracery openings formed by embedding transferred hinges on the thickness of knitwear and education under these hinges open loop (sketch). This structure of the knitted fabric provides good dimensional stability of knitted fabrics, which is a permanent structure of the lower hinge layer, but similar textural effect in the form of blind tracery openings limits the range of art is Loten delicate weaves by forming on the surface of the canvas new textured effect in the form of relief strips, consisting of alternating in the direction of the bending arcs, while maintaining the shape of the canvas.

The offered Jersey is a double weft knitted openwork weave, two hinge layer which is formed by interweaving the surface, and part of the hinge bottom hinge layer is stretched at the same time through the loops of his and the upper hinge layers, and simultaneously through both loops looped layers stretched every second loop of the lower layer as in the direction of the hinge line, and looped pile.

The method of obtaining such a Jersey is to separate the knitting stitch layers of knitwear on two igalnice weft knitting machines with constant (each buttonhole row) alternating in adjacent stitch rows of the transfer loops with even and odd needles of the front needle cases on the needles of the rear needle cases.

In Fig.1 given image stitch patterns such double weft knitted openwork weave. In this hinge structure, each second loop P1the lower hinge layer is stretched at the same time through the loop2his and loop P3the upper hinge layer. Resulting loop P3front hinge sink layer on tolsia wrong side loops P1the lower hinge layer.

Thus, on the surface of the upper hinge layer formed hinge bars, “recessed” on the thickness of the Jersey.

In turn, sketches N upper hinge layer that is not connected to the looped structure of the lower hinge layer under the action of elastic threads tend to straighten up, and their vertical sidelines, located in majitele between, take the form of arcs, curved towards each other and protruding on the surface of the upper hinge layer Jersey. The structure of the side cut of this Jersey is given in Fig.2. Chess location sketches and loops in the adjacent stitch rows of the upper hinge layer of this Jersey ensures formation on the surface of the canvas texture effect in the form of longitudinally spaced recessed by the thickness of the knitted stitch columns relief strips, consisting of alternating in the direction of the bending arcs, while the dimensional stability of the fabric is determined by the structure of the lower hinge layer that remains constant.

The practical implementation of the invention was performed on a weft knitting machine with electronic control of the company Steiger, dressed with pure wool and wool blend yarn. the prometida, 1986, S. 143-148.
