Description

The invention relates to the field of protecting human health from exposure to an electrostatic field.

The presence of an electrostatic field is associated with the conversion of the mechanical energy of a moving subject, dressed in synthetic polymeric materials capable of accumulating electric charges, into an electrostatic field, leading to the appearance of excess electric potential.

In [1], the maximum permissible level of electrostatic field strength is indicated.

It is known that a person is exposed not only to natural electrostatic fields, but also to artificial ones, arising from the conversion of human mechanical energy when using synthetic polymer materials, which are used for the manufacture of household items, interior decoration and clothing items. During the mechanical action of such materials, significant uncompensated charges are generated on their surface, both positive and negative, forming electrostatic fields.

People who have been in the electrostatic field for a long time have complaints of irritability, sleep and appetite disturbances, aggravation of allergic reactions, which necessitates protection [2].

A known method of electrochemical protection of textiles from static electricity (RF Patent No. 2535276), which improves the efficiency of individual protection of workers of modern electrostatic and explosive industries during the operation of protective textiles (clothing) due to the continuous removal of accumulated charges of static electricity from a person to the electrodes of an electrochemical cell protection, which is a sealed bag with two electrodes made of carbon cloth with deposited on its surface with an active layer containing nickel oxide / hydroxide, a polymer electrolyte and a separator.

A special anti-electrostatic suit is known (RF Patent No. 2426483), which can be made in the form of a jacket with a hood and semi-overalls or trousers, that is, clothing items from one element. This clothing primarily provides increased effectiveness of individual protection of workers of modern electrostatic and explosive industries and increased resistance to mechanical stress during the use of protective clothing. In general, protective antistatic clothing is a multilayer package: the top layer is made of antistatic fabric, the lining is a material made from natural fibers. The principle of operation of the developed design is the dissipation of static electricity in areas of greatest risk of accumulation of electrostatic charge by a lattice of metal filaments of the material of additional overlays.

The disadvantages of these analogues is that the use of additional pads that are rigidly fixed only in areas of greatest risk of accumulation of electrostatic charge, which include clothing items, the movement of which can reduce the distance between electrified surfaces, creating a risk of spark discharge. The use of the presented solutions causes difficulty in everyday operation, reduces aesthetic characteristics, and the production process of making a costume is complicated. With a different nature of actions (movements) in subjects, the charge can accumulate in different areas. The physiological parameters of the subject may not correspond to the size of the suit and pads. The proposed level of protection may be either insufficient or excessive.

The closest technical solution is an antistatic suit (Patent US 4596053), made of fabric containing electrically conductive threads. The essence of the solution is that for the removal of electrostatic charge from the skin of the employee, a bracelet is provided that is worn on the wrist and connected to the suit using a button. Next, the charge flowing along the conductive threads is discharged through a wire attached to the belt, which is attached with a plug to the grounding equipment.

The disadvantage of the technical solution of the closest analogue is that the worker becomes less mobile when moving around his workplace, as well as when moving from one workplace to another, since he constantly has to disconnect and attach the protective suit to the grounding equipment.

The technical result of the invention is:

1. Periodic reduction in the level of tension of the electrostatic field accumulated on human clothing.

2. Ensuring the optimal microclimate of the clothing area while maintaining hygiene indicators (vapor permeability, breathability, moisture absorption).

3. Increasing the mobility of the worker in electrostatic production.

The technical result is achieved due to the fact that in the claimed method, the suit of which is made of fabric containing electrically conductive filaments, the kit also includes shoes, into the sole of which k gas surge arresters with a given breakdown voltage are integrated, the suit consists of n> 1 partially overlapping elements clothes, the overlapping surfaces of the elements are made in the form of a woven tape with a high content of conductive threads, which are released counter on the overlapping elements of the clothes.

The claimed invention is illustrated by the following drawings:

FIG. 1 is a general view of the claimed antistatic kit;

FIG. 2 is a schematic illustration of shoes included in the claimed antistatic kit.

The claimed solution is implemented as follows.

The proposed antistatic kit consists of n elements, made of overlapping clothing elements, includes specialized shoes (Fig. 1). In each element of clothing integrated into the process of production of threads from conductive materials (1, Fig. 1), ensuring the drainage of electric charges from the elements of clothing.

For periodic contact of one element of clothing with another use a woven tape (2, Fig. 1). For the manufacture of woven ribbons, threads are made of more durable fibers: linen, cotton, less often woolen and natural silk, connected by simple weaves: linen, twill, less often satin. The woven tape is made of a material in which conductive metallized threads are integrated in the production process in a larger quantity than in the material of the elements of clothing, which are woven on the outside when weaving.

The fabric of the kit elements is composite: the top layer is made of any material whose threads contain a conductive material (the diameter of the conductor is approximately 0.1 thickness of the thread), and the lining in contact with the human body is made of material with natural fiber (cotton, linen). The lining may consist of underpants and T-shirts made of cotton (linen) fabric or knitwear [3].

For end-to-end movement of electric charges from one element of the kit to another, a woven tape is used with a high content of conductive threads for periodic contact between clothing elements.

For periodic and normalized reduction of the electrostatic field when in contact with grounding surfaces, gas surge arresters (HF) are introduced in any way into the sole of the shoe (4, Fig. 2) [4].

The hydraulic fracturing can be integrated into the sole of the shoe by any method, for example, by injection molding: a hot alloy of polyurethane, PVC, rubber is poured into a mold in which hydraulic fracturing is in contact with the bottom of the insole (7, Fig. 2) using contact pads [5 ].

Next, the processed sole is attached to the stitched blank of the shoe (3, Fig. 2). In the shoe blank there are contacts united by one conductor for connection with an insole with a conductive pad on the surface of the shoe and hydraulic fracturing. The shoe insole contains conductive material from the bottom and top (5, Fig. 2).

A conductive pad (6, Fig. 2) on the surface of the boot is necessary for electrical contact with the elements of the suit.

Thus, through the use of a suit with overlapping clothing elements made with a high content of metallized conductive threads, with a lining, as well as the addition of shoes with integrated gas surge arresters, the specified technical result is achieved.
