RU111404U1 - DESIGN OF A CLOTHING MATERIAL PACKAGE FOR PROTECTION FROM LOW TEMPERATURES - Google Patents

Abstract

 The design of a package of clothing materials for protection against low temperatures, containing two layers of sheath material forming the front and back sides of the package, and an insulation pad located between them, characterized in that the insulation pad combined consists of two layers of a three-dimensional non-woven fabric and a feather insulation fixed between them in separate compartments formed by quilting lines, welding lines or stitched bulkheads, while the feather insulation gives the package the required thickness and volume mnoe fabric, insulating the hard feather insulation - soft to the touch.

Description

The proposed technical solution relates to the technology of manufacturing garments for protection against low temperatures, namely, clothes with feather insulation and can be used in the production of work and special clothes.

The quality of outerwear is influenced not only by the materials of the top and lining, but also by the materials that form the insulation pad - insulation. Packages of materials of clothing intended for protection against low temperatures are classified by the type of material used as an insulating pad:

- bags with bulk non-woven fabrics;

- bags with volumetric disjoint insulation;

- bags with cellular insulation.

In bags with nonwoven fabrics, both traditional batting and synthetic winterizer, as well as new synthetic materials with unique properties of domestic and foreign production are used as insulation pad: “Thinsulate”, “Hollofiber”, “Arctic,“ Fibertek ”,“ PerioTek ”,“ Vitar "," Isosoft "and others.

Packages with disconnected insulation, depending on the layers of shell material directly bonded to the insulation, are divided into two-, three-layer and combined. In addition, these packages can be made with a combined shell forming the front and back sides of the package (Bekmurzaev, L.A. Designing products with bulk materials: Monograph / L.A. Bekmurzaev. - Mines: YURGUES, 2001 - P.49- 51).

In packages with disconnected insulation, fluff and feather of waterfowl are widely used in a percentage of 90% and 10%, respectively. The use of feather mass as an insulating pad of heat-protective clothing can significantly reduce the weight of these products, increase heat-shielding properties, but such a heater has a high cost. The increase in the content of the pen in the insulation in order to reduce the cost practically does not affect the thermal resistance of the package. But the quality of the product is deteriorating, since the rigid stems of the feathers significantly reduce the softness of the package. In addition, the migration of the components of the feather-down insulation increases through the punctures of the material of the sheath of the package with the aid of a pen. This disadvantage has the known design of packages with disconnected insulation (RU 2234843 class A41D 31/02, 2004; RU 2286073 class A41D 31/02, 2006; 2286701 class A41D 31/02, 2006).

Closest to the claimed technical solution are packages with a combined shell forming the front and back sides of the package (Bekmurzaev, L.A. Designing products with bulk materials: Monograph / L.A. Bekmurzaev. - Mines: YURGUES, 2001. - P.50 -51). The design of such bags also does not provide their "soft touch" when using fillers with a high content of the pen.

It is known that the thermal resistance of clothes depends on the thickness of the package (Kolesnik, S.A. Designing of multilayer constructions of children's heat-protective clothing / S.A. Kolesnik, G.P. Beskorovaynaya // Modern problems of service engineering and technology: Technical progress in sewing production: Interuniversity collection of scientific papers. - Mines, SRSUE. - 2006. - P.54-55). The thermal insulation properties of the materials are due to the presence of inert air enclosed in them and are little dependent on the type of fibers.

The objective of the proposed technical solution is a constructive solution of packages of clothing materials for protection against low temperatures with feather insulation, which allows to reduce the cost of products while maintaining a given level of thermal protection and sufficient softness to the touch.

The problem is solved in that the design of the package of clothing materials for protection against low temperatures, contains two layers of sheath material that form the front and back sides of the package, and the insulation pad located between them, and the insulation pad is combined - consists of two layers of bulk non-woven fabric and feather insulation, fixed between them in separate compartments formed by quilting lines, welding lines or stitched bulkheads, while the feather insulation gives the package the required thickness, and the voluminous canvas, isolating the hard feather insulation, softness to the touch.

The essence of the technical solution is illustrated in figure 1, which shows a section of the proposed package of materials of clothing for protection against low temperatures. The package consists of two layers of shell material fastened with lines 1, forming its front 2 and wrong 7 sides and a combined insulation pad. The gasket contains two layers of three-dimensional non-woven fabric 4 and a feather insulation 5, fixed between them in separate compartments formed by quilting lines 6. Compartments for filling with a feather insulation can also be formed by welding or bulkheads. Between the shell materials 2, 7 and the insulating gasket above the lines forming the individual compartments an air-filled space 3 is formed.

The inventive design of the package of materials can be used in work and special clothing to protect against low temperatures, the packages of which must have a significant thickness to ensure the required level of thermal protection.
