Description

Technical field

The claimed invention relates to the technology of manufacturing clothing, namely outerwear with synthetic non-woven insulation.

State of the art

The package of materials for insulating outerwear includes the fabric of the top and lining, insulating materials are located between them. One of the most important characteristics of quilted clothing is their thermal insulation ability. Optimizing the insulation efficiency of quilted clothing makes it warmer and more comfortable to wear.

Known from the prior art is the design of a package of special clothing with increased resistance to aerodynamic deformation (see patent RU 2535275 dated 12/10/2014), which contains two layers of shell material: outer and inner. Volumetric incoherent insulation is located between the layers. The layers of the shell material are connected by bulkheads, while one section of the bulkhead is connected to the outer, the other - to the inner layer of the shell. The design contains additional vertical bulkheads made of bulk glued non-woven fabric. The proposed design of the package will increase the ability of the package to maintain and restore its design thermal protection in conditions of increased wind load without increasing the consumption of valuable insulation.

A known design of a package of special clothing with non-cohesive insulation with increased resistance to deformation (see patent RU 2756990 dated 10/08/2021), which has the ability to maintain and restore the calculated thermal protection under conditions of increased wind load and in areas of constant compression of the package. The proposed package contains a cover fabric, a back fabric and an incoherent insulation located between them, while the fastening of the cover and back fabric is carried out by means of main horizontal bulkheads containing additional vertical bulkheads made of bulk glued non-woven material. Vertical bulkheads made of bulk glued non-woven material are two-layer, containing bulk reinforcing elements between layers - an additional elastic element made of bulk non-woven material located longitudinally, and are located along the seams of the vertical connection of clothing parts.

A well-known design of a heat-shielding package with horizontal quilting of variable asymmetry (see patent RU 2387349 dated 04/27/2010), which contains two layers of shell material: external and internal, a bulk insulation located between them, and the bonding points of the layers dividing the package into compartments. The ratio of the lengths of the material of the layers of the shell between the places of fastening of the layers of the compartments varies along the length of the package between adjacent compartments within 0.71<K _def <1.4. EFFECT: invention provides expansion of the model range of heat-protective clothing, a given level of thermal resistance at a lower specific consumption of bulk insulation.

The closest to the claimed technical solution is an alternative quilting according to US patent 20140250575 dated 04/11/2014, used for the manufacture of clothing, which can retain body heat in a low-temperature environment. This invention involves the manufacture of clothing from several layers of quilted fabric. Each layer can be quilted both horizontally and in the form of squares. The thickness of the layers can be different. The thermal insulation material can be one of the following: down, polyfill and fiber ball. In addition, sets of layers can be offset from each other so that the stitches of one set of layers are blocked by an area of another layer heavily filled with insulating material. This quilting option is performed in order to block the flow of cold air through the quilted areas.

The disadvantage of the structures described above is the low dimensional stability and migration of the insulation inside the volume of the package under wind pressure. In addition, the use of a package of these structures limits the possibility of creating silhouette shapes of products, since the material (construction) turns out to be quite voluminous.

Disclosure of invention

The objective of the proposed invention is to create a new design solution for a clothing package with a reduced volume without losing its heat-shielding properties.

The technical result of the proposed invention is the creation of a clothing package design that has the ability to maintain its design thermal protection with a reduced volume (thickness) of the product.

To achieve the set task and the specified technical result, it is proposed to create a design for a package of clothes with a non-woven insulation with quilting, containing two sets of layers, the first of which contains an outer shell material, an additional lining and a synthetic non-woven insulation with a density of 200 g/m ² , quilted together with diagonal stitches in in the form of rhombuses, the second layer contains the inner material of the shell and the second layer of synthetic non-woven insulation with a density of 100 g/m ² quilted together with straight horizontal lines in 2-3 places, depending on the length of the product.

Quilting layers is performed on a sewing machine. Thinsulate, sintepon, sherstepon, isosoft, holofiber can be used as a synthetic non-woven insulation. The diagonal stitch of the first layer is made in the form of diamonds 6x6 cm in size. The second layer is quilted with horizontal lines, the distance between which is 20-25 cm.

Implementation of the invention

In this section of the description, the most preferred embodiment of the invention will be given, which, however, does not limit other possible embodiments explicitly following from the application materials and understandable to a person skilled in the art.

The design of the clothing package is as follows. Take the outer material of the shell, insulation, for example, thinsulate with a density of 200 g/m ² and an additional lining, which is placed between the outer material and the insulation. Quilt this layer with diagonal stitches in the form of rhombuses 6x6 cm in size (see Fig. 1). An additional lining prevents the insulation fibers from crawling out onto the front surface of the product. Next, the second layer of the structure is assembled. They take the inner material and insulation, for example, thinsulate with a density of 100 g/m ² , and quilt together with horizontal lines in 2-3 places, depending on the length of the product, the distance between which is 20-25 cm (see Fig. 2). Thanks to the physical tests of this insulation method (quilting method) in the harsh conditions of the Far North, it is this method that maintains the most comfortable temperature.
