Abstract

The invention relates to the knitwear industry, and more specifically to the knitted foundations for knitted products, can be used as rubber support in the manufacture of underwear and sports products and can improve the quality of the band by reducing its stretchability. For this, the webbing has looped interlocking weft non-elastomeric yarns of co-wired loops of a chain and tricot loops of non-elastomeric yarns in which elastomeric yarns are made in the form of longitudinal wefts. The elastomeric yarns have sections, made in the form of longitudinal straight segments, laid outside the said hinge columns, located between the transverse non-elastomeric yarns, which are a combined two-and one-way weft. Loops of chains are periodically closed. 2 Il.

Description

The invention relates to the knitwear industry, and more specifically to the knitted foundations for knitted products and can be used as a rubber support in the manufacture of underwear and sports products.

The purpose of the invention is to improve the quality of the elastic band by reducing its extensibility.

. Fig. 1 shows a diagram of the structure of the looped structure of the claimed tape in Fig. 2, a graphical and analytical record of the operation of the dies to obtain the proposed tape.

One example of a specific implementation of the base of an elastic tape is a loop structure, the structure of which is shown in Fig. 1. The braid has tricot weave loops 1 of an elastomeric yarn, loops of chains 2 of a non-elastomer yarn, transverse weft non-elastomeric yarns 3 and longitudinal weft Elastomeric yarns 4. Loops of tricot 1 and chains 2 are connected together to form looped columns 5 connected by transverse weft yarns 3. Elastomer yarns 4 have sections 6, where they are laid in the form of straight segments outside the columns of the tangled loops of chains and tights. Transverse weft yarns 3 form respectively single-thread weft 7

and double-ended ducks 8. The loops of the chain 2 are periodically closed 9.

Fig. 2 shows a graphical and analticic recording of the work of the knives to obtain the proposed elastic band, the structure of which is shown in Fig. 1. The numbering of the combs begins with the first one, located behind the back of the needles. Comb 1 applies a tricus interlacing of non-elastomeric yarns with the following order and size of shifts for one rapport; 1-0-1 and 1-2-1 two times, 0-0-1 and 2-1-1 four times, 1-0-1 and 1-2-1 two times, 0-1-1 and 2- 1-0 three times. Comb II will lay longitudinal weft elastomer yarns with the following order and shear size for one rapport: 0-0-1 and 1-1-0 three times, 0-0-1, 1-1-1 twice, 0 -0-0, 0-0-1 and 1-1-0 four times, 1-1-0, 0-0-0, 0-0-1, 1-1-0. Comb III will lay the transverse weft non-elastomer yarns with the following order and shear size for one rapport: 0-0-1 and 2-2-1 three times, 0-0-1, 1-1-1 2-2-1 , 1-1-1, 0-0-1 and 2-2-1 four times, 1-1-1, 0-0-1, 1-1-1, 2-2-1. Gre benkl IV performs laying of chains of non-elastomeric thread with the following order and size of shifts for one rapport: 0-1-1 and 1-0-0 four times, 1-0-1, 1-0-0, 0-1-1 and 1 -0-0 three times, 0-1-1, 1-0-1, 1-0-1-, 0-10-1-1, 1-0-0.

Introduction to the tape structure of longitudinal weft elastomeric sections. yarns made in the form of straight segments, laid out outside the loop-: columns, jointly wired tricot loops and chains and placing them between non-elastomeric yarns, representing a combined two and one-way ducks, as well as periodic looping of chains closed, not complicated The process in the yoke allows the creation of bands with an extensibility of the order of 130–160%, which is much lower than the extensibility of the existing structures in the elastic stretch chains.
