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 made of a fibrous mixture of natural and/or synthetic fibers, and at least one frame layer located outside or inside the material. The layers of material can be made of different thickness, and synthetic fibers may be hollow. Frame layer may be made of Kraft paper, which can be provided with an adhesive layer, a polymeric film, which, in particular, can be metallized, or woven material. The technical result - high thermal insulation characteristics and mechanical properties at small thickness. 7 C.p. f-crystals.

The invention relates to the textile industry, in particular to non-woven materials, and can be used, for example, as the insulating procline 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 poor thermal properties, which does not allow to use it 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 objective of the invention is to create a material with high insulating properties and mechanical properties with a small thickness.

The objective of the invention is solved in that the nonwoven laminate contains several interconnected layers made of a fibrous mixture of natural and/or synthetic fibers, and at least one frame layer located outside or inside the material. Multiple layers increases the heat swistgroup.com.

The layers of material can be made of different thickness, and synthetic fibers may be hollow. The use of hollow synthetic fibers leads to the reduction of thermal conductivity of the material.

Frame layer may be made of Kraft paper, with Kraft paper can be provided with an adhesive layer applied on one or both of its surfaces. Sticky layers simplify the connection process Kraft paper with heat-insulating layers.

Frame layer may be made of polymer film, which, in particular, can be metallized. The execution frame of the layer of polymer film enhances the reflective properties of the material, which are reinforced with the use of metallized film.

Frame layer may be made of woven material.

With the popularity of thermal conductivity of each type of fiber can be pre-set conductivity of each layer and material in General. The use of different frame layers allows to obtain a material with different mechanical properties, such as flexibility, strength, elasticity, plasticity.

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

To impart the necessary mechanical properties (flexibility, strength, and so on, the material contains at least one frame layer. If there is only one frame layer, it can be placed both outside and inside between the layers of material. If the frame of several layers, they can be located both inside and outside of the material.

Frame layer or layers may be made from a polymeric film or Kraft paper, or woven material. The polymer film is joined to the layer of material by passing it together with the layer through the calender. Can be used metallized polymer film.

To simplify the process of connecting the Kraft paper with the adjacent layer of material she supplied adhesive layer applied on one or both of its surfaces. The adhesive before bonding a protective film.

Example 1. The material consists of superimposed and 30% bicomponent synthetic fibers, or in the ratio of 50: 50% synthetic hollow and flax. The frame is located between the fibrous canvases. As the frame layer is Kraft paper coated on its surface an adhesive layer.

Example 2. The material consists of superimposed on each fleece (layers) made of 100% polyester fiber, or including 80% synthetic hollow fiber, or 30% bicomponent synthetic fibers, or in the ratio of 50: 50% synthetic hollow and flax. The frame layer is located on the outer side of the material, which is used Kraft paper printed on one side of the adhesive layer, which frame layer bonded to a layer of fibrous material.

Example 3. The material consists of superimposed on each fleece (layers) made of 100% polyester fiber, or including 80% synthetic hollow fiber, or 30% bicomponent synthetic fibers, or in the ratio of 50: 50% synthetic hollow and flax. The frame layer is located between the fibrous canvases or on the outer side of the material. As a frame layer polymer film is used.

Example 4. The material consists of superimposed on the% of bicomponent synthetic fibers, or in the ratio of 50: 50% synthetic hollow and flax. Frame layers are located between the three fiber canvases. As a frame layer is Kraft paper, and the other in a linen cloth.

Example 5. The material consists of superimposed on each fleece (layers) made of 100% polyester fiber, or including 80% synthetic hollow fiber, or 30% bicomponent synthetic fibers, or in the ratio of 50: 50% synthetic hollow and flax. The first frame layer is located between the fiber canvas, which is Kraft paper. On the outer side of the material is the second frame layer of the metallized polymer film having a reflecting radiation effect.

Example 6. The material consists of a mixture of fibers: polyester, linen and wool in the ratio of 50:30:20 respectively. The frame is located between the fibrous canvases. As the frame layer is Kraft paper, metallized on one side and black on the other hand, to provide respectively the reflection and absorption of radiation.

Example 7. The material consists of superimposed on each of the canvases (layers) of flax and the costs imposed on each other fleece (layers), one of which is made of 100% polyester fiber, or including 80% synthetic hollow fiber, or 30% bicomponent synthetic fibers, or in the ratio of 50: 50% synthetic hollow and flax fibers and the second fibers of wool. The frame layer is located on the outer side of the material, which is cotton fabric.
