Description

(54) BASED-ELASTIC STRUCTURE

one

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

A technical solution is known for the structure of the basics of a squeezed tape, using it 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 sections longitudinal weft elastic yarns placed between the bars of the chains.

Such a looped structure of the prototype web slightly reduces the possibility of band opening during its operation in the product, since, firstly, the transverse weft threads connecting the columns of the chains cannot prevent the unraveling of these columns when the thread of the chain is broken and, secondly, The longitudinal elastic weft yarns are laid in the form of straight lengths, therefore they are retained in the loop structure only due to the frictional forces.

and upon deformation of the stretching of the braid, the elastic thread may come out of the looped structure.

The aim of the invention is to reduce dissolvability.

It is desirable to have an elastic band, in which the possibility of its dissolving when the chain is broken in the columns of the chains would be significantly reduced, which makes it possible to use it as a holdout in underwear and sportswear.

10 The goal is achieved by the fact that

the braid contains columns of the tricone derivative interlaced, connecting with its ends the looped columns of chains with open loops that are connected together with the loops of the derivative of tricone interlacing. The stitches of the tricuscera derivative are connected between the stitches of the stitches of the chains tied together with the stitches of the tricone weave derivative and their lengths. The loops of the tricot derivative are closed.

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

So that the looped columns of the chains are the restraining frame of the braid structure, the stitches of the knit-knot derivative, connecting the stanchions of the chains, are located between the skeletons of the loops of the strings, connected together with the loops of the knit-knit weave, and their pulls.

Performing the loops of the tricot derivative closed weave contributes to imparting little-dispersed properties to the structure of the braid.

FIG. Figure I 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 webbing has looped columns of chains 1 with open loops of elastic yarn, looped columns of a derivative of tricone interlacing (cloth) 2 with closed loops of inelastic yarn, transverse weft nonelastic yarn 3 and longitudinal weft elastic yarn 4. Open loops of chains 1 together with the closed loops of cloth 2. The looped columns of chains 1 are interconnected by transverse weft yarns 3 and the webs of cloth 2, which are located between the skeletons of the loops of chains 1 and their webs. The longitudinal elastic weft yarns 4 are laid between the transverse weft yarns 3 and in the gaps between the posts of the chains 1 with open loops connected together with the closed loops of the felt 2.

FIG. Figure 2 shows the graphic and analytical recording of the operation of the dies to obtain a basic elastic band, the structure of which is shown in FIG. 1. Numbering of combs begins with the first of them, located behind the back of the needles. Comb I carries out the laying of transverse weft non-elastic threads with the following order and shear size for

one rapport: 3-3; O-0. Comb I also carries out the laying of longitudinal elastic weft threads with the following order and size of shifts for one rapport: I - 1. Comb III carries out the laying of weaving cloth with the following order and size of shifts for one rapport: 1-О 2-3. Comb IV cleaves the 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 derivative of tricone interlacing, without complicating the manufacture of the band, reduces its dissolvability compared with the known basics of these elastic bands,

applied, as prodzhechnyh in underwear and sports products.
