Description

Field of technology

The utility model refers to protective clothing, which is a personal protective equipment and is used in extreme and emergency situations, and in particular in accidents, chemical attacks and biological pollution.

BACKGROUND OF THE INVENTION

Protective clothing is known in the art to serve as personal protective equipment, characterized by resistance to the penetration of contaminated liquids under hydrostatic pressure, resistance to the penetration of infectious agents due to mechanical contact with substances containing contaminated liquids and resistance to the penetration of contaminated liquid aerosols, resistance to penetration of contaminated solids. The clothing is made of fabric lined with a membrane.

From utility model CN 2629475 is known medical protective clothing, including left upper part with sleeves, right upper part with sleeves, left trouser leg, right trouser leg and hood, connected by seams, forming a complete garment in the form of overalls. The front left upper part and the front right upper part are connected by a longitudinally located zipper. The garment material is multi-layered, containing an outer polyester layer and an inner membrane layer, fixedly connected by an adhesive layer, which is a polyurethane adhesive. The multilayer material combines a nonwoven layer of fabric treated with a fabric coating technology and a thin membrane layer representing a microcellular membrane. The non-woven fabric layer is made of polyester fibers or non-woven polypropylene textile. Protective clothing has an antitoxic tape that connects each piece of clothing. The inner and outer layers are glued so that when exposed to external influences, they provide double resistance.

The known protective clothing is not elastic enough and does not provide enough comfort to the user, and the membrane is not breathable.

Technical essence of the utility model

The task of the utility model is to create protective clothing that is reliable, functional, creates security in protection from various external physical and chemical influences, including the causes of viruses and infections, and has a free ergonomic appearance. and to create freedom of movement.

The problem is solved by creating a protective clothing, which consists of a left upper part with a sleeve, a right upper part with a sleeve, a left trouser leg, a right trouser leg and a hood, connected by seams forming a complete garment in the form of an overall, such as the front left upper part. and the front right upper part are connected by a longitudinal zipper. The garment material is multi-layered, containing an outer polyester layer and an inner membrane layer fixedly connected by an adhesive layer, which is a polyurethane adhesive.

According to the utility model, the outer polyester layer is made of a knitted polyester elastic fabric, which is pre-treated with silver ions, whereby a protective surface film is formed.

The inner membrane layer is a polyurethane membrane that allows air to pass freely through it.

The outer surface of the faucet is laminated and covered with polyurethane coating, which makes it waterproof.

Around the opening of the hood, the ends of the sleeves and the legs there is an elastic band, which is a multi-core rubber with a polyester braid. The seams connecting the parts of the garment are double and are additionally glued with polyurethane tape.

The outer polyester layer after its adhesion to the inner membrane layer is unilaterally additionally hydrophobized with fluorocarbon, forming a secondary protective layer.

In this embodiment of the protective clothing made of multilayer material, with glued seams and waterproof zipper, resistance to penetration of contaminated liquids under hydrostatic

3693 Descriptions to utility registration certificates № 08.1 / 17.08.2020 pressure, resistance to penetration of infectious agents due to mechanical contact with substances containing contaminated liquids, resistance to penetration of contaminated liquid aerosols, resistance to penetration of contaminated solid fragments.

Protective clothing provides better functionality and comfort in operation, due to its elastic and stretchy construction due to the elastic knitted structure of the outer polyester layer, achieving a strong chemical and mechanical bond, which allows the clothing to be used repeatedly. The polyurethane membrane makes the clothing breathable, and the hydrophobicity with fluorocarbon, as well as its treatment with silver ions provide antibacterial and antiviral protection.

Also, the protective clothing is made wide enough around the body in order to create freedom of movement without having to create a weight to move and create effort and tension and fatigue from users during use.

Examples of implementation of the utility model

As shown in the attached figures, the protective clothing includes a left upper part A with sleeve 2, a right upper part B with sleeve 4, a left leg 11, a right leg 12 and a hood 13 connected by seams 5 forming a complete garment in the form of an overall. The front left upper part 1 and the front right upper part 2 are connected by a longitudinally located zipper 6. The clothing material is multilayer, consisting of an outer polyester layer 7 and an inner membrane layer 8, which are fixedly connected by an adhesive layer 9, which is a polyurethane adhesive. .

The outer polyester layer 7 is made of a knitted polyester elastic fabric, which is pre-treated with silver ions, whereby a surface protective film 16 is formed.

The inner membrane layer 8 is a polyurethane membrane. The outer surface of the zipper is laminated and covered with polyurethane coating 10, where the zipper 6 is waterproof.

Around the opening of the hood, the ends of the sleeves 2, 4 and the legs 11,12 there is an elastic 14, which is a multi-core rubber with a polyester braid.

The seams 5 connecting the parts of the garment are made double, and are additionally glued with polyurethane tape 15.

The outer polyester knitted layer 7, after being glued to the inner membrane layer 8, is unilaterally additionally hydrophobized with fluorocarbon, forming a secondary protective layer 17.

Application of the utility model

The composition of the materials used for the manufacture of protective clothing includes only products that are absolutely harmless to the user chemicals and raw materials.

The outer polyester knitted fabric 7 is made on knitted machines from textured polyester multifilament silk. Then chemical bleaching and application of silver ions is performed to obtain the surface protective film 16. Drying and heat fixing, followed by lamination of the outer polyester knitted fabric 7 with the inner membrane layer 8, by connecting a polyethylene adhesive layer 9. After cutting of the product and sewing with double seams, they are glued with double adhesive tape in warm air, as 100% of the seams are covered with tape. The last operation of the production of the multilayer material is also hydrophobicity.
