Abstract

BASED KNITTED KNITTING, in which each loop stitch contains tricot loops alternating with loops of chains, two of which are open and one is closed, characterized by the fact that, in order to expand the assortment possibilities by obtaining a round braid, it is made of double weave from three systems yarns, one of which contains elastomeric yarns, wound into each loop of the column, with this, the length of each loop of the non-spun thread is longer than the length of the loop of the sudrome string by 15-20%. moreover, in each hinge post closed loop of the wire chain Zai with a shift by one needle step.

Description

The invention relates to the manufacture of knitted fabrics, in particular, to the basics of elastic bridges and can be used as an elastic structural element, for example, for the SL-10 headset.

Known for the basics of a combined jersey, in which each loop stitch contains tricot loops alternating with loops of a chain, two of which are open and one is closed i.

A disadvantage of the known knit fabric is that it cannot be obtained in a round section.

The purpose of the invention is to expand the range of possibilities by obtaining a round band.

The goal is achieved by the fact that the basis of a combined jersey, in which each loop of the column contains tricot loops, alternating with loops of the chain, two of which are open and one closed, is made of double weave from three systems of threads, one of which contains elastomeric n, iti The length of each loop of the non-elastomeric thread is more than the length of the loop of the elastomer thread by 15-20%, and in each loop column there are closed flying chains that are twisted with a single needle shift

step.

FIG. 1 shows a graphical record of the fundamentals of a closed elastic band in FIG. 2, an analytical record of masonry filaments on needles; in fig. 3 is a diagram of the transfer of the comb; in fig. 4 - installation of navoy with thread mi on the machine.

Each structural element consists of double loops, including a loop of two textured yarns and a loop of elastomeric yarn, which are depicted by a single line 1 (figure 1). FIG. 4 are marked with two spandex yarns and 3 with a textured yarn. Understanding different yarn systems provides round section, and with different lengths of the loop, specified elongation and doubleness. Alternating the closed loops of tricot face-wrong side ensures reliable fixing of the elastomeric thread in the structure tapes.

Example. Elastic braid on the basis of a 24-class Raschel-class car with two needle beds and two ear combs. At the same time, two polyamide textured yarns with a thickness of 3.33 teksu 2 and an elastomeric spandex thread 50 tex are simultaneously bonded. Rapport weave vertically.ali consists of two alternating sections.

The first section has a closed loop of a single leotard formed on the needles of the first needle bed and open loops of a double chain (the first loop of the double chain being formed on the needles of the second needle bed and the second on the needles of the first needle bed)

The second section includes a closed loop of a single leotard formed on the needles of the second needle bed, and open loops of the double chain (the first double loop of the chain being formed on the needles of the first needle bed and the second on the needles of the second needle bed).

The length of the loop is from a textured thread 7.5 mm, from an elastomeric thread 6.5 mm.

Samples of an elastic band of the proposed weave are made of textured yarns of various thickness p (combined with one-dimensional yarns

spandex 50 tex.

Sample I is made of textured ntexi 10 texX2 and with BT-Ex ep more than ne 20%. Sample I was made of two textured yarns 3.33 Tex 2 .eu (.8, n by 15%).

Sample III is made as proposed. Characteristics of the samples are presented in the table.

As indicated in the table, the first sample has an enlarged diameter and increased extensibility, which does not satisfy the requirements.

The second sample, although it has a uniform plush closure, however, has insufficient stretchability, which also does not satisfy the requirements.

The third sample, as can be seen from the table, satisfies the requirements, namely it has a circular cross section with a diameter of 2 mm, a good

uniform stuck with plush loops and 300 extensibility

As a result of the experiment, it was determined that the braid has a good, uniform covering with plush loops while wounding two textured yarns 3, 33 tex l X2 iodine nitispandex 50 tex.

Thus, a pre-elastic elastic band meets all the requirements placed on it as a structural element of the headset, 5 In addition, the surface with the effect makes it possible not to create painful sensations (during the operation of SL-10 products).
