WRAPPING YARN

The utility model relates to the textile industry, in particular, to the production of wrapping yarns intended for the production of fabrics for technical and household purposes, and haberdashery and technical non-woven fabrics.

EQUIPMENT LEVEL

Single yarn or thread is rarely applied directly to any one. Only a small amount is used as a weft for the manufacture of certain types of fabrics. Usually from single yarn

make a twisted straight, which then after several operations,

Improving its quality, they are used in weaving, knitting and other purposes.

The closest in technical essence and the achieved effect is twisted yarn with evenly alternating turns, consisting of 2 components of the same linear density, as a result of which the thread has the form of an elongated spiral (Figure 1): 3otikov VB "The mechanical technology of fibrous materials, M: Gislepfom 1963, p.302.

So, twisted yarn from 2 components 1 and 2 was obtained by joining (trimming) and giving a twist, the direction of which is opposite to the direction of the primary twist of a single yarn.

The process of twisting the yarn consists of two operations: crushing and. The crushing operation is preparatory to torsion and consists in combining (adding) a given number of threads or yarn into one strand called a crushed yarn. Carrying out the trimming, it is necessary to ensure the equality of the tension of the single components to be pressed together and their number to remain constant along the length of the strand.

Shredded yarn is subjected to torsion, in which each single thread, like fibers in the yarn, takes a helical shape and creates radial and tangential pressure on adjacent single threads.

An example of the use of equipment for producing twisted yarn: - a two-stage method:

TV-150 reed machine, K-83-1TM torsion machine;

Md /.

- a one-stage method of torsion involves combining the processes of crushing and torsion on one machine:

TKM-224 reeling and twisting machine; double twisting machine VTS-07/2.

The different tension of the chopped single strands, the inequality of their relative elongation causes non-simultaneous rupture of the component strands of the twisted yarn, reducing its strength.

A significant drawback of twisted yarn is the limited assortment capabilities in the manufacture of technical fabrics, as well as haberdashery and ribbon products.

ESSENCE OF A USEFUL MODEL

The utility model is based on the task of creating a wrapping yarn, which will provide creep of the technical result, which consists in expanding and enriching the assortment of yarn (threads) and products from it.

This technical result is achieved using machines operating on the principle of a hollow spindle. The proposed wrapping yarn consists of a core containing one or more components and a braid, for the formation of which one, two or more components are used.

To obtain a wrapping yarn as a braid and core can be used:

1. Yarn single or twisted with a linear density of 12.5 tex tex, different in raw material composition, containing:

- natural fibers (cotton, linen, wool, etc.) or mixtures thereof;

- chemical fibers of linear density 0.11 tex - 2.2 tex (viscose fiber, polyester, polyamide, polyacrylonitrile, polypropylene, modacrylic, phenylone, arselon, aramid, etc.).

- mixtures of natural and chemical fibers.

2. The threads are viscose, polyester, polyamide, polymer, CBM, phenylone, oxalone, etc., severe and dyed, linear density 5.0 tex 144.4 tex.

3. The combination of single, twisted yarn and yarns in various versions in terms of quantity, raw material composition, linear density, color, or several characteristics at the same time.

A prerequisite for achieving the claimed technical result is the observance of the specified parameters when receiving a wrapping yarn:

-constant and sufficient tension of the core;

- the twist in size should be such that the turns of yarn (or threads) that make up the braid are tightly and evenly located around the core with the goal of completely closing it, creating a loamy effect.

Examples of wrapping yarn are presented in Figure 2 a, b, c. Table 1 shows examples of the raw material composition and linear density of KOMnoHCSHTOB wrapping yarn.

The use of various components as the core allows you to get a wrapping yarn, which combines the strength, protective, special, aesthetic, comfortable properties of nasural fibers with the strength and other specified properties of chemical fibers and threads.

INFORMATION CONFIRMING THE POSSIBILITY OF IMPLEMENTING A USEFUL MODEL

Wrapping yarns using natural and chemical fibers and yarns can be made at textile enterprises using hollow spindle machines, using modernized spinning and spinning machines, provided that the necessary tension and twisting parameters are created and controlled.
