Description

The invention relates to hosiery, in particular to shielding socks, and can be used as part of a set of special clothing to protect personnel from electromagnetic fields of the radio frequency range (RF EMF).

Known conductive socks, made with the possibility of use with conductive shoes. Socks contain intersecting conductive threads included in the structure of the material, and consist of upper and lower conductive parts. In this case, the upper and lower conductive parts of the socks are separated by an insert made of a material without electrically conductive threads and are not galvanically connected (RU 2206252 C2, class А41В 11/00, 06/20/2003).

These socks provide equalization of the total free potential of a person’s charge with a negative potential of the earth’s charge due to the electrical contact of biologically active points located on the foot with the ground and due to the possibility of electric exchange processes with a positive charge of the atmosphere from the skin located under the upper part of the sock.

A disadvantage of the known socks is that they do not protect the user from EMF RF, in addition, they are used only in conjunction with conductive shoes.

Known socks that are shielded from electromagnetic waves, made of bamboo, polyester and linen fibers in combination with stainless steel wire, followed by ultraviolet treatment (CN 103876306 A, class A41B 11/00, 06/25/2014).

Socks that are shielded from electromagnetic radiation are also known, obtained from yarn based on copper wire and Korean cotton fiber with a mass ratio of 1: 6, respectively (KR 20150130067 A, class A41B 11/00; D02G 3/04; D02G 3/44; D04B 1/26; D04B 9/46, 11/23/2015).

The disadvantage of the above socks is their relatively low shielding and operational properties, which does not allow their use in sets of special clothing for protection against EMF RF.

The technical result of the invention is to increase the shielding effect and operational properties of socks designed to protect against electromagnetic fields of the radio frequency range.

This result is achieved by the fact that the shielding socks consist of a bead, a pagolenka 13-15 cm high, a trace, a heel and a toe, the outer layer of which is made of tinsel yarn of linear density 38-40 tex, consisting of a multifilament polyamide yarn wrapped in a silver-plated copper-plated flattened wire with a diameter of at least 0.06 mm, with their content in tinsel yarn (15.0-20.0) and (80.0-85.0) wt. %, respectively, and a composite filament with a linear density of 9.0-9.2 tex, consisting of a polyurethane filament spun with a polyamide filament, and the inner insulating layer of the socks is made of cotton yarn.

At the same time, tinsel thread, combined thread, and cotton yarn are used in a ratio of 54.0: (12.0-13.0) :( 33.0-34.0) wt. % respectively.

At the same time, a polyamide thread with a filament number of 24, a linear density of 6.7 tex with a twist of at least 200 cr / m was used as a multifilament polyamide yarn.

A distinctive feature of the proposed invention is that when using in the outer layer of socks a tinsel yarn of linear density 38-40 tex, consisting of a multifilament polyamide yarn, wrapped in a copper silvered flattened wire with a diameter of at least 0.06 mm, when they are contained in tinsel yarn (15 , 0-20.0) and (80.0-85.0) wt. %, respectively, in combination with a combined thread of linear density 9.0-9.2 tex, consisting of a polyurethane thread, wound with a polyamide thread, as well as performing an inner layer of cotton yarn with the stated ratios of raw materials and their technical characteristics, a synergistic effect of increasing operational properties of socks and degree of protection against EMF RF.

It has been established experimentally that the use of other synthetic, natural and metallic threads and yarns with other technical characteristics and in other mass ratios than those stated does not allow socks with high shielding and performance properties to be obtained.

The claimed invention is illustrated in the drawing.

The drawing shows a General view of the shielding sock.

The toe consists of a side 1, an elongated pagolenka 2 13-15 cm high, a trace 3, a heel 4 and a toe 5.

Socks are made on single-cylinder circular hosiery machines mod. ANGE 19, 15 class, Uniplet company (Czech Republic).

In their production, the following types of yarn and threads are used:

for the outer (facial) layer:

- tinsel thread of linear density 38-40 tex according to TU 14.12.30-004-00302178-2017;

- a combined thread of linear density 9.0-9.2 tex, consisting of a polyurethane thread, wrapped with polyamide thread, imported (Malaysia, China and others),

for the inner insulating (back) layer:

- cotton (cotton) yarn of linear density 25 tex according to GOST 9092;

for laying on board 1 and pagolenok 2:

- latex thread with a diameter of 0.28-0.3 mm, wrapped with polyester textured thread with a linear density of 8.4 tex, a total linear density of 100 tex according to TU 8147-003-00321945-99.

In the manufacture of tinsel yarn, a polyamide thread of linear density 6.7 tex, multifilament (the number of filaments is 24) with a twist of at least 200 cr / m in accordance with GOST 10063-93 and a copper wire with a diameter of at least 0.06 mm in accordance with GOST 2112-79 were used.

To obtain a flat section, the copper wire is flattened by drawing. When applying a thin layer of silver, the galvanic method is used: the wire is passed through an electrolyte saturated with silver. The silver content is 5% (about 3 microns of silver on the surface of the wire).

The content of raw materials in the tinsel yarn is, wt. %: multifilament polyamide (PA) thread - 15.0-20.0, copper-plated silver-plated flattened wire - 80.0-85.0.

Tinsel thread, combined thread and cotton yarn are used in the ratio, wt. %: 54.0: (12.0-13.0) :( 33.0-34.0), respectively.

The manufacturing technology of shielding socks includes the following operations: 1) preparation of raw materials for knitting; 2) knitting and quality control; 3) sewing on toes and turning socks on the front side; 4) formation; 5) technical grading.

Toes are sewn on the thinned section of the workout with a polyamide textured thread of linear density 3.3 tex × 2 on a sewing machine mod. Rosso 025Е.

Socks are formed on electrical forms mounted on a forming machine. The size of the shapes corresponds to the size of the socks. After the formation of the product is placed on the trays for tracking during the day.

Shielding socks are made elongated, laying 1 and pagolenok 2 twisted latex threads in each row of knitting, with knitted heel 4 and toe 5.

The socks are knitted with smooth plating, which ensures the formation of loops of tinsel on the front side in combination with a highly extensible polyurethane thread, braided with textured polyamide thread, and on the wrong side - loops of cotton yarn.

Knitting sites is made by the following weaves:

bead 1 and pagolenka 2 - smooth plating on the basis of false elastic weave with rapport 2: 1 with the laying of a twisted elastomeric thread in each row of knitting;

trace 3, pre-calcaneal and pre-arterial sections, heel 4 and toe 5 - interlacing smooth plating on the basis of the smooth surface.

Socks are made in the following sizes: 27-29, 31-33.

The table shows the technical and operational characteristics of the experimental samples by examples.

Examples 4 and 5 are control.

Tests of experimental samples of socks were carried out as part of a shielding set of protective clothing in accordance with GOST 12.4.172-2014 and GOST 12.4.141-99.

Using the proposed invention will provide shielding socks with high performance properties and reliable protection against EMF RF.
