RO126082A0 - Multilayered protective gloves - Google Patents

Abstract

The invention relates to some mechanical, thermal and chemical protection gloves having high degree of resistance and dexterity. According to the invention, the gloves comprise a base leather layer (1) carried out by cutting and assembling by some seams (3), which may also be in combination with textile materials (2) covered subsequently, integrally or partially, with a layer of elastomers, with or without inner lining.

Description

The invention relates to multilayer protective gloves having the basic layer executed by cutting and assembling by sewing entirely of leather or in combinations thereof with textile materials, subsequently covered wholly or partially with a layer of elastomers, with or without inner lining.

The current state of the art

Protective gloves made by cutting and assembling by whole leather or leatherette, or in combinations with fabrics or knits, are known as traditional and common use. These gloves are sometimes provided with the lining having the role of increasing comfort, the role of ensuring thermal insulation or mechanical damping. This type of gloves has the disadvantage of not providing protection against moisture and liquid chemicals, being permeable both through the material itself and through seams. In addition to the fact that they do not provide protection, do not withstand or maintain their qualities in contact with moisture or certain chemicals, the skin, the chip or the sewing thread. Another disadvantage of these gloves is the low adhesion of the skin or the glitter on any type of surface, the result being the diminution of the gloves dexterity. These gloves degrade rapidly with the outer seams permanently exposed to abrasion in the contact areas with the manipulated objects.

Also known are protective gloves made of elastomers with or without textile support. The main disadvantage of these gloves is the low mechanical resistance to abrasion, cutting, tearing and drilling. Synthetic fibers with high resistance to abrasion, cutting and tearing can be used for textile support, but their use greatly increases the cost of the product without solving the problem of puncture resistance. Certain synthetic fibers used for textile support cause discomfort in contact with the user's skin. This type of gloves also has a low thermal resistance.

Purpose of the invention

The object of the invention is to make multilayer protective gloves that combine the mechanical and thermal protection and resistance of leather gloves with the impermeability, dexterity, protection and chemical resistance of elastomeric gloves.

Exposure of the invention

The problem solved by the invention is to create high-dexterity multilayer protective gloves that are resistant and provide protection against moisture, mechanical, chemical and thermal risks in low price conditions. These gloves contain a basic layer made entirely of leather or its combination with textile materials, made by cutting and assembling by sewing. This base layer is subsequently completely or partially covered with an elastomer layer. The base layer can be provided partially or totally with the inner lining with the role of increasing comfort, ensuring thermal insulation or mechanical damping.

Advantages of the invention

The multilayer protective gloves that are the subject of the present invention have the following advantages over the leather gloves:

are moisture resistant ensures moisture protection are chemically resistant

- ensures the chemical protection have the seams protected against contact with the manipulated objects have a high level of dexterity

Simultaneously, compared to elastomeric gloves with or without textile support, they have the following advantages: they are resistant to perforation, they provide protection against perforation, they have a higher degree of resistance to abrasion, breakage and tearing, they provide a higher level of protection against abrasion, breakage and tearing. have a higher degree of thermal resistance ensures a higher level of thermal protection

An embodiment of the invention

The following is an example of an embodiment of the invention in connection with Figure I, which shows a multilayered glove made of leather markings (1) in combination with fabric markings (2) assembled by seams (3). The base layer thus executed is subsequently partially covered with a PVC layer (4). The PVC layer (4) is represented in the drawing through hatched areas. Detail (a) represents the longitudinal section through the tip of the glove's index finger.
