(54) BASED-ELASTIC STRUCTURE

one

The invention relates to the field of knitwear, a more specifically, to the piece basics of the product and can be used in the manufacture of underwear and sports products.

Known technical solution of the structure of the basics of zanna elastic tape, using the case as a prod 1.

The fundamentals of the elastic band have chains of chains with open loops of inelastic yarn, connected by two systems of transverse weft inelastic yarns, between which are laid in the form of straight segments longitudinal weft elastic yarns placed between the columns of the chains.

Such a looped structure of the prototype braid slightly reduces the possibility of bracing of the braid during its operation in products, because, first, the transverse weft threads connecting the chains of the chains cannot interfere with the unraveling of these bars when the thread of the chain is broken and second, the longitudinal elastic weft yarns are laid in the form of straight segments, therefore, are held in a looped structure only by

friction and during deformation of stretching the elastic band the thread can go out of the looped structure.

The purpose of the invention is to reduce the bandage ability.

The goal is achieved by the fact that the braid contains columns of chains with loops of elastic yarns and columns of a derivative of tric interlacing of inelastic threads, connecting with their spindles the looped columns of two groups of chains, with open loops of chains of non-elastic yarn, loops of the derivative of tricone weave and the loops of the chains of elastic yarn are connected together, and the stitches of the loops of the chains of elastic yarn are made in the form of straight segments.

The loops of the loop of the derived tricot corpus connecting the columns of the chains are located between the cores of the loops of the chains of the non-elastic thread and their broaches. The loops of the tricot 2Q weave derivative and the loops of the chains of elastic thread can be made closed.

The introduction of a tricot derivative into the braid structure makes it possible to drastically reduce its dissolvability when the HHfH chains are broken, since the tricot derived weave is an additional framework.

The presence of loops of chains made of elastic yarn prevents the elastic yarn from leaving the looped structure during tensile deformations.

So that the looped columns of the chains are the containing skeleton of the ribbon structure; The stitches of the stitch derived triangle interlacing, connecting the strings of the chains, are located between the cores of the stitches of the strings of the inelastic thread and their stitches.

Performing the loops of the tricot derivative and the chains of closed elastic yarn contributes to imparting little-spreading properties to the string structure.

FIG. 1 shows the basic structure of a zannaya elastic band; in fig. 2 - graphic and analytical recording of the work of dies.

One example of a specific embodiment of the basics of a knotted elastic band is a loop structure, the structure of which is shown in FIG. 1. The braid has looped columns of chains i with open loops of inelastic yarn, looped columns of the tricycle weave derivative (cloth) 2 with closed loops of inelastic yarn, transverse weft nonelastic yarns 3, and looped bars of chains of 4 of elastic yarn. The open loops of the chains 1 are connected together with the closed loops of cloth 2 and the closed loops of the chains of elastic thread. The stitch posts of the chains I are interconnected by transverse weft yarns 3 and the cloth pulls 2, which are located between the cores of the loops of the chains 1 and their runs. The stitches of the loops of the hinge columns of the chains 4 of elastic thread are made in the form of straight segments.

FIG. Figure 2 shows the graphic and analytical recordings of the operation of the dies to obtain the basics of a stretched elastic band, the structure of which is shown in Fig. 2. 1. Numbering of combs begins with the first of them, located behind the back of the needles. Comb I performs the laying of transverse weft non-elastic threads with the following order and size of shifts for one rapport: 3-3; O-0. Comb H makes an elastic thread with the following order and size.

shifts for one rapport: 1 - 1 p. 1. Comb III makes an interlacing of cloth with the following order and size of shifts for one rapport: 1-0; 2-3. Comb IV carries out 5 laying of chains with the following order and size of shifts for one rapport: O-1, 1-0.

Introduction to the looped structure of the basics of a knitted elastic band of a tricycle derivative and chains of elastic strings, without complicating the manufacture of the band, reduces its dissolvability as compared to the known basics of elastic bands used as prodorgechnyh in underwear and sportswear.
