Description

The proposed technical solution relates to the clothing industry and can be used in the manufacture of outerwear with disconnected insulation, providing a given level of quality of finished products.

The specifics of forming packages with voluminous, disconnected insulation has a significant impact on the calculation of the thermal insulation properties of packages and products in general. In the case of the formation of a heat-shielding package with voluminous, disconnected heaters, these heaters are placed between two layers of shell material, which are divided into compartments by quilting lines, welding or gluing lines.

The formation of the bulk shape of the heat-shielding package is associated with the deformation of the shell materials and the insulation layer. At the same time, shaping of clothing packages cannot be obtained without wrinkles and wrinkles. The negative effect of the presence of wrinkles and wrinkles in the heat-insulating bag is explained not only by the deterioration of the aesthetic properties of the heat-insulating bag, but also by the violation of the thickness of the insulation layer, which can provoke overcooling of the human body.

To eliminate wrinkles and wrinkles, recesses are introduced along the quilting line, the longitudinal deformation of the compartments of heat-insulating bags is taken into account, etc. In the future, the development of elastic shell materials that will allow uniform distribution of deformation along the surface of the part is considered, as a result of which volumetric-spatial heat-insulating bags can be obtained in the form of regular tori (Bekmurzaev L.A. Material research and design of garments based on composite systems [Text], monograph: L.A. Bekmurzaev, T.V. Deni .. Ova EV Nazarenko et al, edited by Prof. L. Bekmurzaev - Mines: VPO "SRSUES", 2009. - 32-33 s).

A known design of a two-layer heat-insulating bag with curvilinear bulkheads in places of bonding layers (Pat. RU 2361491 C2, IPC A41D 31/02. The design of a two-layer heat-insulating bag with curvilinear bulkheads in places of bonding layers [Text] / Authors: Tungusova N.A., Chizhik M. A., Kargapolova T.Yu., Gokhnadel M.V. Patentee of the State Educational Institution of Higher Professional Education “Omsk State Institute of Service.” - 2007133084/12; filed September 3, 2007; publ. July 20, 09). The design contains two layers of shell material: external and internal, a volumetric disjointed filler is located between the layers. The layers are interconnected through bulkheads of a curved configuration. These bulkheads are connected to the layers of the package by means of additional rectilinear parts.

The design disadvantage is a significant increase in material and labor costs due to the curved design of the bulkheads and the presence of additional joints. Such bulkheads during cutting lead to significant loss of materials, the properties of the curved bulkheads vary in length due to a change in the angle between the strands of the bulkhead material and the slices, which determines the uneven stretchability along the length of the bulkhead and, accordingly, the uneven thickness of the heat-shielding package, reducing the quality level of finished products.

A known design of a two-layer heat-insulating bag with bulkheads, which contains the outer and inner layers of the shell, a volumetric incoherent insulation located between them, the places of bonding of the layers (Pat. 2479234 C2 of the Russian Federation, IPC A41D 31/00 / Design of a heat-insulating bag with bulkheads [Text] / Authors : Bekmurzaev L.A., Nazarenko E.V., Denisova T.V., Kuznetsova I.Yu. Applicant and patent holder of Ural State Pedagogical University - No. 20111130349/12; application. 20.07.2011; publ. 04.20.2013). The layers of material of the shells of different lengths are connected by bulkheads consisting of n longitudinal parts of different lengths.

The proposed technical solution requires an accurate mathematical calculation of the size of the bulkheads. The presence of additional seams on the bulkheads increases the complexity of manufacturing a heat-shielding package.

The technical solutions listed above to reduce the deformation of heat-insulating bags during shaping are provided for heat-insulating bags with bulkheads. Unresolved is the problem of reducing or uniform distribution of deformation in two-layer structures of heat-insulating bags without bulkheads.

Closest to the claimed technical solution is a two-layer design of a heat-shielding package containing two layers of sheath material (external and internal), a volumetric incoherent insulation located between them, and places where the layers are fastened with quilting lines (I. Brink. Development of production of down clothes / I. Yu. Brink // University proceedings. Technology of light industry. - 1991. T.34. - No. 1 - p. 77-80).

The disadvantage of this design is the unevenness of the thickness over the area of the heat-shielding package as a result of random accumulation of folds and creases formed as a result of shaping, i.e. envelopes with heat-shielding packages of parts of the body The formation of plots with folds and creases leads to a decrease in the level of quality and heat-shielding properties of finished products.

The objective of the proposed technical solution is to increase the quality level and maintain a given level of thermal resistance over the entire surface of two-layer heat-insulating bags after their formation.

The problem is solved due to the fact that the design of the heat-insulating bag with the inner wings comprises two layers of sheath material: external and internal, volumetric incoherent insulation, places of bonding of the layers, characterized in that on the inner layer of the material of the sheath the curtain is processed for elastic braid located inside the heat-insulating package. At the same time, the design of the heat-shielding package with the inner wings is characterized in that the amount of pulling back the wings should not exceed 1/6 of the length of the wings.

The invention is illustrated in FIG. 1, which shows the design of a heat-shielding bag with an inner wings.

The two-layer design of the heat-insulating bag contains the outer 1 and inner 2 layers of the sheath material, a volumetric incoherent insulation 6 located between them, and the places where the layers are fastened with quilting stitches 3, and the backstage 5 located inside the heat-insulating bag is processed on the inner layer of the sheath material. The drawstring is designed for threading the elastic braid 4, which allows you to evenly distribute the fit on the inner side of the shell that occurs when forming the bulk shape of the heat-protective package. The amount of contraction of the inner wings depends on the thickness of the heat-shielding package and the rigidity of the shell material and should not exceed 1/6 of the length of the wings. At the same time, the proposed design of the seam for bonding shell materials makes it possible to hide through holes from the quilting line on the inner side of the heat-shielding package and reduce the migration of the insulation.

The elastic properties of the elastic braid facilitate the formation of the three-dimensional shape of the shell of the heat-shielding package and make it possible to achieve a uniform distribution of the fit along the quilting lines. In addition, the absence of through holes on the inner side of the heat-shielding package eliminates the migration of insulation through punctures with a needle. Thus, the proposed design of the heat-insulating bag with the inner wings allows you to save a predetermined level of thermal resistance over the entire surface of the heat-insulating bags after their formation and to improve the quality of heat-insulating clothing.
