The pocket is a three-dimensional arch, concave outwardly, the gasket is made of a non-woven hydrophilic material and is placed in the pocket with the formation of a fold protruding towards the arch and a tubular cavity inside it. 1 C.p. f-ls, 6 ill.

Description

The invention relates to the manufacture of outer, mainly insulating clothing, and can be used in special heat-protective clothing with a water- or air-tight upper layer to increase its heat-protective and hygienic qualities at the same time:

The aim of the invention is to reduce the noted drawbacks, namely, improving the hygienic, heat-shielding and ergonomic properties of clothes while ensuring high manufacturability.

Figure 1 is a perspective view of a multilayer heat-shielding bag for insulating workwear; figure 2 is a section aa in figure 1; in Fig.Z is a variant of the package with a volumetric pocket having an arched bottom (partially bent); Fig. 4 is an embodiment of a bag with a through pocket (without bottom); figure 5 - the inner part of the package and pocket with a gasket forming a central tubular cavity; figure 6 is a variant of the manufacture of insulating

overalls. using a multilayer heat-shielding package.

A multilayer heat-insulating bag consists of an outer 1 and an inner 2 layers of textile material, between which there is a gasket 3 made of a non-woven hydrophilic material (for example, a needle-punched fabric based on wool fibers). The outer (outer) layer of the package is made in the form of a volumetric (arched) pocket formed by longitudinal seams 4, and possibly an arched bottom 5. Between the outer layer 1 and gasket 3 in the pocket, an elastic plate 6 is installed (inserted with tension) along its entire width of foamed waterproof material (for example, foamed polyethylene), which abuts against the side zones of the pocket (at the seams 4), actually forms an arched shape of the bag and ensures its contact with the surface of the material of the outer layer 1. Plate b can be made of several layers (Fig. 4). At the same time, gasket 3 with its sides with a singing XI

by the power of longitudinal seams 7, it is attached to the inner layer 2 of the bag with the formation of a central protruding fold 3 and a tubular cavity 9 between them. The central protruding fold 8, abutting against the elastic plate 6, contributes to the formation of a strong shape of the whole bag. In the manufacture of insulating clothing, multilayer heat-insulating bags are contacted by an external, usually moisture-proof layer of clothing 10 and can form its single internal part, for example, a removable lining (Fig. 6f).

A multilayer heat shield is made and used as follows.

When forming the bag, initially, to its inner layer 2, usually of a hydrophobic material such as a PVC sheet, seams 7 are attached to the gasket 3, made in the form of a strip of hydrophilic material, so that a protruding fold 8 and tubular are formed in its central part cavity 9, dimensions. which are predefined. Then, seams and strips of thin waterproof fabric, such as Bologna, or of film material are attached to the inner layer 2 from the same side to form a cavity in the pocket, in which an arched bottom can be provided 5. In the formed pocket, which due to small bevels, it can also have a trapezoidal shape; elastic plates 3, for example, made of foamed polyethylene, pre-sized in size are installed with a slight tension. This forms an arched pocket shape. Further, by connecting the individual packages together, an internally removable lining of overalls can be formed (Fig. B).

The proposed package works as follows.

In addition to the usual enhanced heat-shielding properties associated with the use of a multilayer heat-insulating material, this package has additional air cavities and has the ability to maintain the heat-insulating material in a relatively dry state, which significantly increases the heat-shielding properties of clothes. In addition, the heat-insulating bag allows sweat-absorbing liquid (sweat) to be absorbed by the bag layer 2 further by the gasket 3 and can be removed through channels 9 through an additional perspiration system (not shown).

The manufacture of the hydrophilic gasket 3 in the form of protruding folds allows

intensify the moisture transfer process: moisture absorbed by the hydrophobic layer accumulates in hydrophilic overlays, which have a zigzag surface, create a wick effect.

The use of an arched form of pockets for the outer layer of the bag reduces the contact area of the heat-insulating gasket with the outer shell of the workwear

which reduces heat transfer through a layer of clothing.

The process of manufacturing a heat-shielding gasket including the proposed multilayer bag is not difficult. The inner hydrophobic shell is made whole, and the shell design should be as similar to the body configuration as possible to ensure close contact of the skin with the inner layer of the napkin.

Hydrophilic pads, represented in the product in zigzag folds, are cut in the form of rectangles and placed in places requiring enhanced thermal protection: shoulders, chest, back, etc.

In areas characterized by increased perspiration, several hydrophilic can be placed in one pocket

longitudinal stripes, with the central fold remaining protruding to maintain the arched shape of the pocket.

The combination of materials different in appearance and structure in a heat-insulating bag gives clothing a number of useful properties.

The textile material of the inner layer has good drapability and the necessary hygiene; the hydrophobicity of such a material provides a dry contact surface of the inner layer.

The hydrophilic material, represented by longitudinal strips, absorbs moisture, but at the same time does not significantly lack construction.
