Description

This invention relates to the apparel industry, in particular to double-sided fur garments.

A known method of manufacturing a multi-layer jacket is that the main parts of the jacket are formed from several parts, the thickness of which is equal to the thickness of the corresponding material package. As you move away from the shoulder seam, the number of layers in the package of each subsequent part of the part is reduced compared to the previous one, and parts with the same heat-shielding properties are combined into common layouts.

The disadvantage of this method is the formation of several multi-layer webs, which greatly complicates the process of producing clothes. At the same time, the increase in expenditure is increased: the time for completing the layouts of parts depending on the number of layers in the canvas.

The closest to the technical essence of the invention is a method of making insulated clothing, which consists in pre-making a package of materials from top fabric and bulk insulation, for which a thermoplastic glue is applied in the form of glue dots to the wrong side of the top fabric and is connected to bulk insulation during pressing and heating on a convex cylindrical surface.

However, the bag thus formed performs the functions of a portion of a garment package, since causes the use of another layer - lining. The presence of the lining necessitates its cutting, processing and connection with the top of the product, which complicates the process and increases the consumption of bonding materials.

The purpose of the invention is to reduce the labor intensity of manufacturing and increase exploitation

characteristics of heat-protective clothing while maintaining hygienic properties.

This goal is achieved by the fact that heat resistant clothing is made of a composite material that performs the functions of the entire package of clothing and consists of two layers of artificial fur. One layer of fur is used as the material of the top, and the other layer of fur as a lining and thermal insulation pad. The connection of the two layers is carried out by means of a thermoplastic film, which is at the same time a wind-proof gasket.

FIG. 1 shows a general view of heat-proof clothing; Fig. 1 is a cross section of a composite material that performs the functions of the entire clothing package; in fig. 3 shows patterns of seams used for joining garment details.

A method of manufacturing heat-protective clothing is carried out as follows.

The main material 1, artificial fur, which serves as the material of the top (Fig. 2), is superimposed with a thermoplastic perforated film 3, and the last layer is covered with a layer of artificial fur 2, which serves as a lining and thermal insulation strip. Materials 1, 2, 3 thus complex are directed into a high-temperature field, where, as a result of thermal processes, film 3 is straightened and materials 1 and 2 are combined into a composite. The process of joining materials into a composite is controlled by temperature, compressive force, and material advance rate. The regulation of the heat-shielding properties is carried out by changing the coefficient of the living section of the film, which is the ratio of the hole area to the total area of the film.

The proposed method is implemented as follows.

PRI me R 1. Thermal protective clothing is made of a composite material (FIG. 2) having a front layer 1 and a lining layer 2. For the front layer 1, artificial fur with a pile of polyacrylonitrile fibers is chosen, and for lining layer 2, artificial fur with a pile of a mixture of polyester and polyacrylonitrile fibers. Layers 1 and 2 are interconnected by applying a 0.04 mm thick plastic film between them with a live section coefficient of 0.01. At the same time, the technological parameters of the process of combining the raw materials into the composite are chosen within the range: the temperature of the heating surface is preferably 160-165 ° C, the pressure is mainly 70-80 kgf / cm2, the rate of advancement of materials is 3 m / min to achieve a peeling strength of 507.5 N / m, air permeability of 28.2 dm3 / m2, with.

PRI mme R 2. Thermal protective clothing is made of a composite material having a face layer 1 and a lining layer 2. For the face layer 1, fake fur with a pile of polyacrylonitrile fibers is chosen, and for lining layer 2, faux fur with a pile of polyester and polyacrylonitrile fibers. Layers 1 and 2 are interconnected by applying a 0.04 mm thick polyethylene film between them with a live section coefficient of 0.07. At the same time, the technological parameters are chosen within the range of: the temperature is preferably 160-165 ° C, the pressure is preferably 70-80 kgf / cm2, the rate of advancement of materials is 3 m / min, in order to achieve the strength of delamination of the obtained composite 240.9 N / m and air permeability 60, 5 dm3 / m2.s.

PRI me R 3. Thermal protective clothing is made of a composite material (composite) having a front layer 1 and a lining layer 2. For the front layer 1, an artificial fur with a pile of polyacrylonitrile fibers is chosen, and for a lining layer 2, fur with a pile of blends of polyester and polyacrylonitrile fibers. Layers 1 and 2 are interconnected by means of a polyethylene film with a live section coefficient of 0.05 and a thickness of 0.04 mm. At the same time, the technological parameters are chosen within the range: the temperature is preferably 160-165 ° C, the pressure is preferably 70-80 kgf / cm2, the advancement speed of materials is 3 m / min to achieve a peeling strength of 312.2 N / m and the air permeability of the composite is 51.0 dm / m.

The production of heat-protective clothing made of a composite material with a different coefficient of the living section of a film of various thickness is carried out in the same way. The use of a film with a thickness of less than 0.04 mm leads to a deterioration of the strength properties of the composite. Thus, for example, the use of a film with a thickness of 0.02 mm with a coefficient of the living section K 0 provides a strength during delamination equal to 16.5 N / m, which is significantly below the norm. When using a film more than 0.07 mm thick, the strength properties of clothes from

The composite increases slightly, but there is a sharp increase in stiffness. Thus, the indicated film thicknesses of 0.04-0.07 mm are optimal.

The results of the study of the properties of a composite material with different perforation rates are tabulated.

Thus, it follows from the table that the air permeability of heat-protective clothing can be adjusted through the use of a perforated film. Thus, for the manufacture of warmed clothes (air permeability B 60 dm / m. S), a film with a coefficient of live section K 0.07 is used. To make very warm clothes (air permeability B 10 dm / m. S), the film is chosen with a coefficient of the living section of not more than 0.01. A film with a live cross section ratio in the range of from 0.01 to 0.07 is used to make warm clothing.

Cutting the garment parts consists of cutting one web of the obtained composite. The processing and joining of the cut parts are performed with special stitches, for example, flexing (FIG. 3 a), butt (FIG. 36) or edging (FIG. 3), using the finishing elements 4 (leather, suede, braid, inlay, etc.) .

The use of finishing elements in the processing of parts of clothing and faux fur of various structures and colors in the manufacture of composite material allows you to update and expand the range of outerwear to protect against cold. Exclusion from the technological process of operations for cutting and processing parts of the lining, thermal insulation and

windproof pads reduces labor intensity and increases productivity. The absence of these parts indicates the minimum material intensity of clothing made in this way.

The proposed method can be used in the manufacture of garments from other pile materials.
