(57) Abstract:

The essence of the invention: at least one outer side of the non-woven material sewn from natural fibers of cotton or other cellulose fibers, applied heavily compacted canvas of biologically decomposable fibers. Non-woven material is intended for use in construction. 9 C.p. f-crystals,4 Il.

The invention relates to the textile industry and can be used in the construction and packaging materials, and relates to a nonwoven fabric made of natural fibers.

Known structural biology insulating materials used in the construction of buildings, especially residential buildings. For reasons of efficiency and to avoid noise loads it is impossible to refuse from reliable heating, cooling and sound insulation.

Typically used necesitaban or laminated metal film felts (Petry) mineral wool, canvas on the basis of glass fiber in the form of insulating plates, as well as paintings from the webs sheep wool, crushed newsprint, protected from damage and destruction by pests and fire boric salts, and made Inoi wool as well as fiberglass product is very fragile. When processing it and it breaks into fragments, whose diameter is smaller than 2, and a length of less than 5 microns. These fine particles will settle in the lungs of man, are not displayed and are not destroyed.

The above biological insulation materials have the disadvantage that they are limited in number, cannot be composted, and also too expensive.

Known non-woven material made from natural fibers of cotton or other cellulose fibers, which are stitched to stabilize the fibrous canvas [1]

A disadvantage of the known materials are also poor insulating properties and material instability.

The objective of the invention is to provide a nonwoven material, while providing an implementation of the invention the technical result consists in the improved insulating properties, ease of recycling and composting of non-woven material, as well as to improve the stability of the material used as packaging material and reducing its cost.

This technical result in non-woven material containing natural fibers, namely algaesia fact, that, at least on one outer side of the nonwoven material used as a heat and/or sound insulation Mat in construction caused compacted canvas of biologically decomposable fibers. In addition, it is preferable that the fibers deposited hydrophobic agent, an anti-rot, anti-fungi or pests, and/or remedy for preventing the ignition.

At least the outer side provided with a layer of biologically readimage material as potato starch, and/or alginate, and/or the like, which is applied by wetting and consistent drying.

Another advantage is that the reinforcing fabric, knitted substrate is introduced into the fibrous layer.

This reinforcing fabric, knitted substrate are connected by a needle, the bonding of biologically decomposable adhesive such as potato starch, stitching, knitting and/or stitch-bonding method.

Non-woven material filled with biologically erodible means such as starch or alginate, and then dried.

It is preferable that the nonwoven material has a surface weight in the range from 300 to 3000 g/is from 50 to 500 g/m2.

Non-woven material, at least one external side can be Kairouan aluminum foil.

Especially, it is preferable that two or more mats of non-woven material superimposed on each other and glued to ensure the manufacture of the material fittings by cutting out from a pile and if necessary with subsequent revision.

Applications of the invention are designated insulation of roofs and walls in the construction sector, outdoor sound and heat insulation, and insulation of pipes, fittings and air ducts.

Cotton, in particular, has all the good properties of the natural material wood. In systems designs using cotton no need to embed any perezagruzila. Cotton protects against structural damage, as it has the ability of wood to absorb and again to give moisture.

According to the invention the non-woven material is made from natural cotton or other cellulose fibers, which are stitched by the needle to stabilize the fibrous canvas. Such non-woven material is biologically completely falling apart and has sufficient strength to be PR is outylook, and in this case, as a filler or insulator commonly used in wrapping the cardboard.

According to one preferred forms of embodiment of the non-woven material, provided that he, at least on one outer side is covered with a layer of biologically erodible agents such as potato starch and/or alginates, and/or the like, caused by wetting and drying. By wetting the surface of the fleece after the drying process becomes continuous, dense. Fiber, thus, may not exude from the clutch of non-woven material.

After applying a layer of nonwoven material becomes very elastic, detects springy properties and features absorbing and insulating effect. Even when exposed to sharp objects or corners and edges that grip nonwoven hardly punched.

In particular, this material has a weight of one square unit within 300 to 3000 g/m2. The material can be manufactured in rolls or already adapted to the relevant requirements not only of heat and sound insulation, as well as packaging.

A further advantage lies in the fact that non-woven material, at measures the biologically decomposable fiber. This form of execution is particularly suitable for heavily used packaging material.

Heavily compacted webs or firming woven, knitted substrate can be at least partially surrounded by a hydrophobic layer to prevent the penetration of water or moisture into the package.

Alternative or additionally, non-woven material can be terminated firming woven textile substrate, the nonwoven material in the form of a Mat, for example, the average surface fleece positioned horizontally surface of the Mat.

Turned out to be advantageous to connect a stabilizing woven, knitted substrate by flashing needles, bonding biologically erodible adhesives, for example, potato starch, stapling, binding, and/or combinations of the latter. For certain applications it may make sense bleaching of cotton fiber or cellulose fiber. Whitening can be performed on a non-woven material to form a fleece or salanoa the fleece.

A particular advantage of non-woven material is that the fibers have very high suction ability. Along with potential uses for packing breakable Escorial suitable as cleaning or cleaning of sconce, in particular, after it has already been used on the package.

Non-woven material for such purposes is made primarily as a lightweight with a weight in the range from 50 to 500 g/m2.

Non-woven materials, as described before, can be used almost everywhere where still used plastic tapes gasket air bags, corrugated cardboard, wrapping paper or similar packing materials. Nonwoven materials are provided to the consumer in rolls or sliced. As to strengthen the structure, coating or impregnation, there may be a variety of combinations.

If non-woven material in any form of execution, as described above, impregnated biodegradable agent, such as starch or alginate, and finally dried, I get relatively rigid fittings that can be cut strictly on the path. They are primarily used as cushioning material for sensitive to damage products and can replace molded from polystyrene foam packing details.

In this case, two or more mats or plates may be dabela cut to the desired shape and, if necessary, completes the revision.

The predominant use of non-woven material, in particular, when he was already once or repeatedly used as the packaging is, to put it into use in crushed or cut form as substitute materials such as shavings, cubes, granules, etc. from plastic (foam polystyrene or other), usually used for packing goods, and in this form the nonwoven material may preferably serve as filler.

Non-woven material according to the invention is a multi-purpose with the possibility of re-production and hassle-free utilization, as it has no toxic fractions and biodegradable. In this case, the material after grinding or cutting can be used as a substitute for peat.

It is advantageous to use non-woven material as blagonamerennogo Mat and, in particular, in horticulture. These mats after they will absorb the water, you can install pot plants or plants transplanted with a clod of earth, thus saving on regular watering.

Non-woven material made in the form of a Mat, can be used to collect (suction) Britanie described in the examples of the attached drawing.
