RU2244771C1 - Double-layer warp-knitted fillet fabric - Google Patents

Abstract

FIELD: manufacture of warp fillet fabric for producing of knitted domestic and technical articles, in particular, netted material for trampoline.

SUBSTANCE: double-layer warp-knitted fillet fabric has meshes with sides defined by loop courses of double-layer tricot lines joined to one another by means of binder defined by felt underlaps. Knitted fabric is composed of loops defined by threads of four systems. All thread systems form loops on every other course, with courses of odd thread systems including underlaps of even thread systems. Courses of even thread systems comprise elongated underlaps of odd thread systems.

EFFECT: increased strength of knitted fabric and wider range of usage.

Description

The invention relates to the production of warp knitted sirloin and can be used for knitting household and technical products.

Known warp knitted sirloin knitwear containing cells, the sides of which are formed by looped columns of two-layer chains connected to each other in bundles by cloth broaches, and containing weft threads connecting looped columns of cell sides and knitted into bundles [1].

The disadvantage of this structure is its low strength.

Known warp knitted sirloin knitwear containing cells, the sides of which are formed by soil threads from two or more tricycle chains, and ligaments are formed by cloth broaches. It additionally contains weft threads, which partially replace the soil loops [2].

This knitwear has insufficient strength, since at break, the simultaneous inclusion of all the thread systems in the work is not ensured due to the uneven load distribution.

The technical result of the present invention is to increase the strength of knitwear.

The specified technical result is achieved by the fact that the two-layer warp knitted sirloin knitwear contains cells whose sides are formed by looped columns of two-layer tricot chains and are interconnected by bundles formed by cloth broaches. The knitwear consists of loops of four systems of threads, forming loops through the row so that the rows of threads of odd systems contain elongated broaches of threads of even systems and vice versa, rows of threads of even systems contain elongated broaches of threads of odd systems.

Figure 1 presents a graphic record of weaving. Figure 1 shows that the sides of the cells consist of triple chains of four systems of threads I, II, III, and IV, each of which forms loops 1, 2, 3, and 4 in the facial loop columns, as well as 1a, 2a, 3a, and 4a in the wrong looped posts. The bundle is made of cloth broaches 5, 6, 7 and 8. All thread systems form loops through a row. For example, the odd systems of threads I and III in the odd rows P ₁ , P ₂ , etc. form loops 1, 2, 1a and 2a, and the threads of even systems stretch in the form of elongated broaches 9 and 10. In even rows of P ₂ , P ₄ , etc. loops 3, 4, 3a and 4a form the threads of even systems II and IV, and the threads of odd systems stretch in the form of elongated broaches 11 and 12.

Double-layered fillet knitwear can be obtained on a double-circuit rachel machine with reed needles, having four combs. All combs are seasoned with threads through one ear needle and perform masonry according to the graphic recording shown in figure 1. Knitwear can be knitted from natural, artificial, synthetic or blended yarns, the linear density of which is selected in accordance with the class of the knitting machine.

The knit of the described structure has high strength, since at break all four systems of threads work simultaneously, which allows maximum use of the strength of all threads.

The proposed knitwear can be used for sports equipment, in particular, for a trampoline net.
