Nonwoven laminated material

 

(57) Abstract:

The invention relates to the textile industry, in particular to non-woven materials, and can be used, for example, as insulating spacers in clothing for low or high temperatures are used, in particular, in construction, for the manufacture of sleeping bags, etc. layered Nonwoven material contains several interconnected layers of different thickness, made of a fibrous mixture of natural and/or synthetic fibers, and at least one frame layer located outside or inside the material, which is made with at least one reflecting or absorbing the radiation layer. Reflecting or absorbing layers can be performed on one or both sides of the frame layer. Frame layer on the one hand can be accomplished with a reflective layer, and on the other hand - with an absorbing layer. The frame layer is made of Kraft paper or plastic films, or woven material and is provided with an adhesive layer applied on one or both of its surfaces. Synthetic fibers are hollow. The technical result - high heat-shielding properties. 5 C.p. f-crystals.

Image is for example, as insulating spacers in clothing for low or high temperatures are used, in particular, in construction, for the manufacture of sleeping bags, etc.

Known multilayer non-woven material containing multiple interconnected layers made of a fibrous mixture of natural and synthetic fibers interconnected (A. C. of the USSR №1806233, IPC D 04 H 1/42, 1993).

Known material has insufficient protective properties and may not be used in products that cannot be used in heat material of greater thickness. In addition, a known material can be easily stretched, losing their flat shape, which complicates its use in the garment industry in the manufacture of insulated clothing, as well as in the manufacture of protective clothing.

The problem is solved in that the nonwoven laminate contains several interconnected layers of different thickness, made of a fibrous mixture of natural and/or synthetic fibers, and at least one frame layer located outside or inside the material, which is made with at least one reflective or tap the Yes fibers, to obtain materials with different thermal conductivity. The use of different frame layers allows to obtain a material with different mechanical properties, such as flexibility, strength, elasticity, plasticity.

Reflecting or absorbing radiation layers can be performed on one or both sides of the frame layer. Alternatively, the frame layer on the one hand can be accomplished with a reflective layer, and on the other hand - with an absorbing layer.

Can be used hollow synthetic fibers.

Frame layer may be made of Kraft paper or plastic films, or woven material with the frame layer may have an adhesive layer applied on one or both of its surfaces.

The possibility of carrying out the invention is illustrated in the following.

Nonwoven laminated material contains several interconnected hypoproteinemia layers. Each layer of material made of a fibrous mixture of natural and/or synthetic fibers, interconnected, and there may be layers, made from a combination of synthetic and natural fibers and consisting only of synthetic or natural filaments is available both on the outside and inside between the layers of material. If the frame layers will be few, they can be located outside and inside the material. To reduce thermal conductivity of synthetic fibers may be hollow.

Frame layer or layers may be made from a polymeric film or Kraft paper, or woven material. Frame layer may be adhesive layers on one or both sides, which simplifies the process of its connection with insulating layers. The polymeric film may be connected with the insulating layer by passing it together with the insulating layer through the calender.

SUBSTANCE: invention relates to an apparatus for colourless patterning of a textile fabric made of mutually interlaced and thus strengthened natural or synthetic fibres, preferably of a nonwoven fabric such as a wadding web, which is also dried in the case of a wet treatment such as hydrodynamic needling. The apparatus comprises a housing and a revolving drum provided therein, whereby the textile fabric is pressed by an overpressure and underpressure against the drum having perforations so that the cross-sectional areas of the perforations generate a picture pattern on the textile fabric, wherein an external peripheral surface of the drum being subject to drawing is provided with perforations depicting an image, which perforations act in diverse pattern-imparting fashions on the textile fabric resting thereon. Moreover, the drum and its external peripheral surface are microperforated as a whole and thus fluid-permeable, and the pattern-imparting perforations are sized larger than the microperforation of the surface supporting the textile fabric, Moreover, the textile fabric is capable of leading the fluid away from the entire surface in a region of the pictorial pattern and also beyond peripheral regions of the pictorial pattern.
