Description

The utility model relates to the field of garments, namely to gloves that can be used as under-gloves (inserts) for rubber, latex, polyethylene, nitrile and other types of air- and water-impermeable gloves made of synthetic materials used in household activities during cleaning, washing, cleaning, repairing, in medicine, construction, service industry, etc.

From the general level of technology in the indicated field of technology, a variety of technical solutions are known for gloves that perform a protective function against the skin of the hands when a person works in household, chemical, medical, construction spheres, in the service sector, in the food industry, that is, in those areas where the skin of the hands can be exposed to harmful effects as a result of interaction with appropriate aggressive substances and environments, including liquids, and when it is required to protect the health of other people, to prevent contact of the skin of the human hands with materials (for example, with food, when performing operations, etc.)., i.e., ensuring sterility. As such gloves are currently mainly used gloves made of synthetic air and waterproof materials, including rubber, latex, nitrile, polyethylene, polyvinyl chloride, etc. The advantages of these gloves are, of course, their protective properties (water resistance, sterility), ease of production and therefore low cost. However, the known disadvantages of air and water resistant synthetic gloves are:

- the lack of breathable properties of the material of gloves leads to rapid fogging of the hands in them due to the lack of air inside the gloves, as a result of which prolonged use of these gloves becomes uncomfortable, unpleasant and harmful to the skin of human hands;

- synthetic materials of air- and waterproof gloves with direct, especially long-term interaction of the skin of a person's hands with them can cause skin allergic reactions, which in this case cause additional discomfort and inability to use them; especially this disadvantage of synthetic gloves is relevant for people suffering from allergic skin reactions, as well as those who have unhealed lesions on the skin of their hands (wounds, scratches, sores, etc.);

- air and waterproof gloves often fit tightly to the skin of a person's hands to ensure safety when working in them, which makes it time consuming, lengthy and uncomfortable to put them on and off, especially taking them off sweaty hands of a person, as a result of which, after taking off, these gloves, even in the absence of damage to them, it is impossible to reuse.

To solve the problem of the laboriousness of putting on synthetic gloves, powdered gloves are used, which are easier to put on, since the synthetic material of the gloves does not stick together when the powder is applied. However, the powder used in them most often only enhances allergic reactions when using gloves, since it is the powder that is an excellent mediator for the transfer of, for example, natural latex protein to the skin of a person's hands, the patient's skin, as well as to a food product (site "DISPOSABLE PRODUCTS" // Which gloves to choose - powdered or powder-free? // Electronic resource, publication date 04/15/2019 URL: https://dproducts.by/articles/kakie-perchatki-vybrat-opudrennye-ili-neopudrennye/ (accessed 13.08. )).

It is also now known to use powder-free synthetic gloves that are easy to wear, such as latex-free, powder-free disposable surgical gloves made of ultra-thin and soft synthetic polyisoprene. The inner polymer coating makes donning easier. The micro-texture of the surface ensures optimal grip. Highly elastic, non-slip and tear-resistant. Perfect fit, providing high tactile sensitivity (HARTMANN website // Peha®-isoprene latexfree // Peha-isoprene latex free -operating-room / surgical-gloves / latex-powder-free-gloves / peha®-isoprene-latexfree - peha-isoprene-latex-free # products (accessed 13/08/2020)). However, these gloves do not solve the problem of hand fogging in them, and the risk of an allergic reaction of the skin of the hands to synthetic material is not completely eliminated.

Also in the prior art, various solutions of gloves are presented, which are gloves made of natural, breathable ("breathable") fabric, covered in whole or in part with synthetic air and waterproof material (for example, cotton gloves with latex coating - site "ASPECT. The main aspect of your safety "// Cotton gloves with latex coating // Electronic resource URL: https://nsk.aspektsnab.ru/catalog/sredstva-zashhity-ruk/perchatki-trikotajnye/s-lateksom/ (accessed 14.08.2020) However, as the main disadvantages of these gloves, one can single out the laboriousness and expensive nature of their production in comparison with conventional synthetic or cotton gloves, as well as the fact that often the air- and waterproof material in them does not cover the entire surface of the gloves, which makes them insufficiently safe in use, since, obviously, aggressive materials will eventually get on the skin, as well as the fact that high or low temperatures will be clearly felt by humans when using them. That is, these gloves are limited in their field of application. At the same time, in the case of covering the entire surface of the gloves with an air and waterproof material, there will be a lack of lack of air and fogging of hands in them. It is also obvious that they will be disposable, until the first damage to the integrity.

To solve the above problems, the prior art contains solutions for combined (compound gloves), including the use of insert gloves, each layer in which is a separately removable / put on gloves.

Known technical solution for a foreign patent for invention No. JP2005307404 "WATERPROOF GLOVES AND INNER FILM FOR THEM" (priority date 23.04.2004). This technical solution is characterized in that it is a composite glove consisting of an inner layer, which is in direct contact with the back and palm of the hand, and an outer layer, which is formed so as to cover the entire outer side of the inner layer of the glove, and a waterproof layer of film, which is located between the inner and outer layers.

Known technical solution for a foreign patent for invention No. EP0972459A1 "Glove insert" (priority date 07.16.1998). This technical solution is characterized by the fact that it is a textile insert of a glove, consisting of two textile parts and containing elements of fingers, thumb, palm, cuff, hand entrance and peripheral outer edge, on which the first textile part of the glove is connected to the second textile part for formation of a peripheral seam at the peripheral edge. At the same time, the seams, including the peripheral seam, are waterproof, therefore the glove as a whole is waterproof.

Known technical solution for a foreign patent for invention No. KR200485109Y1 "INNER GLOVES FOR RUBBER GLOVES" (priority date 04/26/2016). This technical solution is characterized by the fact that it is a glove for a rubber glove, which is able to smoothly absorb sweat or moisture, easily separates from the rubber glove, is versatile and suitable for single use. The glove consists of fingers, palm and wrist. The outer part of the glove is made of viscose non-woven fabric and has a defined area. The inner part of the glove is composed of a rayon non-woven fabric having the same area as the top of the glove to cover the fingers, palm and wrist. The outer and inner parts of the glove are made of artificial silk non-woven fabric and are excellent at absorbing moisture and sweat. A seam portion for fastening the outer and inner portions of the glove is formed on the outer side of the inner portion of the glove, so that the fit feeling of the upper and lower portions of the glove is improved. The outer and inner parts of the glove can be securely fastened, and an air channel can form between the sewn parts, and the hands on the inside of the glove can remain dry.

The closest technical solution (prototype) in terms of a set of essential features is a technical solution for a foreign utility model patent No. CN205597209U "Protective rubber gloves with a medical combination to prevent irritation" (priority date 04/28/2016). This technical solution is characterized by the fact that it is a combined medical gloves, consisting of three gloves - inner cotton, then a polyethylene lash glove, then rubber. In one embodiment of the invention, all gloves are removed and donned sequentially — first cotton gloves, then plastic film gloves and medical rubber gloves. The inner surface of the cotton glove is in contact with the user's skin, thereby avoiding contact between the rubber and the human body, so that it is suitable for allergy sufferers from medical personnel; more preferably, a cotton glove made of pure fine cotton has a sweat wicking function so that it is comfortable to wear and overcomes the disadvantages of traditional rubber gloves. Due to the use of polyethylene film, not only the waterproof character of the glove is achieved, but also the easy putting on / taking off of the rubber gloves.

The following essential features of the prototype coincide with the claimed technical solution: the use of gloves made of breathable ("breathable") hypoallergenic cotton material as liners for air and waterproof gloves made of synthetic material.

The above patented technical solutions have the following disadvantages:

- in two solutions, the third layer of gloves is necessarily used - polyethylene (patents No. JP2005307404, CN205597209U), which is designed to facilitate putting on / removing the outer layer of the glove from the inner one. The need to use these polyethylene gloves complicates and increases the overall cost of using the corresponding combined gloves, and also creates an additional barrier to air, which makes it difficult for air to access the skin of the hands in gloves; - in patent No. KR200485109Y1, the outer and inner parts of the glove-insert are made of non-woven material made of rayon and rayon, while cotton has advantages over rayon (rayon) in terms of hypoallergenicity, hygroscopicity (moisture absorption), strength. In general, the glove has a rather complex device, which makes the process of their production more expensive; - also according to patent No. KR200485109Y1 (paragraphs [0017]) the seam connecting the palm and the back of the glove is overlock. At the same time, any characteristics of this seam are not indicated, and therefore this seam cannot be guaranteed to be strong and reliable enough to ensure long-term operation of the glove. In addition, the overlock seam of standard parameters creates interference and friction between the fingers of the hand and causes discomfort when using such a glove; - in patent No. CN205597209U, all layers of gloves - cotton, polyethylene, rubber - fit tightly to each other, as a result of which in the space between them and between the skin of the hand and the cotton glove (especially considering that rubber gloves have their own very tight fit to the hand and as if pulling it down) not enough air will get in, the hand will sweat. Also, if the cotton material from which the inner layer of the gloves is made is not sewn tightly enough, the seam will quickly disperse and these gloves will become unusable. At the same time, it is obvious that when using an intermediate polyethylene layer of the glove, the outer rubber glove will slide over the polyethylene and can be involuntarily removed from the hand at any time during operation.

In contrast to the above-mentioned analogs, in the technical solution declared for registration, the gloves made of natural fabric, the palmar and back sides of the gloves made of natural fabric are joined together along the edge by an external zigzag seam of certain parameters.

Accordingly, the technical result of the proposed technical solution "Natural fabric gloves" is that due to the use in the outer zigzag seam connecting the palmar and back sides of the glove, the seam width from 1 mm to 3.5 mm and the stitch density up to 2 mm increases the strength and wear resistance of the outer zigzag seam, as a result of which the service life of the glove is increased.

The technical result is achieved by the fact that a natural cotton glove is a natural cotton fabric used as an insert (glove) for an air and waterproof glove made of synthetic materials, characterized in that the palm and back sides of the natural cotton glove are connected between along the edge with an outer zigzag seam, while the width of the outer zigzag seam is from 1 mm to 3.5 mm, the stitch density of the outer zigzag seam is up to 2 mm.

The claimed technical solution is illustrated by a drawing, where figure 1 shows a schematic representation of a natural fabric underfloor, where the palmar (1) and back (2) sides of a natural fabric underfloor are joined together along the edge by an external zigzag seam (3).

To obtain a technical result, the utility model can be implemented in the following preferred manner, which does not exclude other methods of implementation within the framework of the claimed utility model formula.

The offered glove consists of natural cotton fabric and is made by joining the palmar (1) and back (2) sides with an external zigzag seam (3). In this case, the width of the outer zigzag seam (3) is from 1 mm to 3.5 mm, the stitch density of the outer zigzag seam (3) is up to 2 mm. This glove is used exclusively as a liner for an external air and waterproof glove made of synthetic material: rubber, latex, polyethylene, nitrile, polyvinyl chloride, etc. reaction. Due to the implementation of the under-glove made of natural cotton fabric and the outer zigzag seam of the under-glove, while using the proposed under-glove and the outer air- and waterproof glove made of synthetic material on the hand, better air exchange is provided due to the formation of an air space in the place of tension of the elastic outer glove on the seam protrusion, which ensures breathable ("Breathable") nature of the glove when used with a synthetic glove, there is a healthy heat exchange between the skin of the hands and the air, the skin of the hands does not sweat, as a result of which it is possible to work in this glove for a longer time and without harm to the skin of the hands. Also, the use of an external zigzag seam in the glove allows for a short period of time after using gloves to remove the outer glove made of synthetic material and the glove from the hand due to the fact that the outer glove, when removed from the hand, hooks onto the outer zigzag seam of the glove, as a result of which both gloves are removed straightaway. At the same time, during the operation of gloves, for example, when working with materials, including those that are dangerous or harmful to the skin of human hands, with hard surfaces, with tools, etc., the outer glove made of synthetic material is not removed involuntarily from the glove, since the use of an outer zigzag seam provides a better adhesion of the outer glove to the inner glove due to the tension of the elastic outer glove on the projection of the outer zigzag seam of the glove. Also, the use of a zigzag stitch increases the service life of the overlock, since the proposed zigzag stitch is made with a width of 1 mm to 3.5 mm with a stitch density of up to 2 mm, which makes this stitch, compared, for example, with a standard overlock stitch, more durable and wear-resistant ... In practice, this seam does not diverge from the outer synthetic glove during operation. Also, the use of the outer seam in the glove prevents irritation of the skin of the hands, which would occur when the skin of the hands interacts with the inner seam, and therefore increases the duration of the use of gloves while working in them.

The novelty of the presented utility model lies in the fact that the use of an external zigzag seam of a certain width and stitch length for joining the palmar and the back of the glove of a certain width and stitch length provides an increase in the safe service life of the proposed protective glove made of natural fabric and an external synthetic glove and, in general, an expansion of the arsenal of protective gloves is achieved using glove inserts.

The proposed natural fabric backing is currently being prepared for industrial production.
