The invention relates to the field of light industry, and is intended for processing tissue to change its qualities and properties.

A method of producing fiber. The essence of the method lies in the fact that perform pre-grinding of mineral pinacoidal crystalline form, and then its fine grinding and mixing with the polymer. Next, the resulting mixture is powdered mineral with spinning a polymer fiber [RF Patent №2208069, IPC(7) D01F 9/18].

The known method is simple and effective, but it does not provide the processing of tissue in rolls.

Also known a method of obtaining a carbon material with biocidal properties, the modified particles of nano-silver [RF Patent №2202400, IPC(7) B01J 20|/20]. For carrying out the process prepare a solution of silver nanoparticles, conducting exposure of the carbon material in a solution of silver nanoparticles. This method is time-consuming, since the production of reactive solution requires the preparation of special solutions, and the shutter speed carbon material in a solution of silver nanoparticles carried out for 9 hours.

There is also known a method of obtaining a fabric of carbon fibers by continuous tissue carbonization of cellulose fibers [RF Patent №2257429, IPC(7) D01F 9/16]. In this way, to reduce the heating temperature, the Cagnes, continuously passing the camera carbonization, is subjected to heat treatment including heating the tissue at the initial stage to a temperature of 250-350 degrees. with some average speed 10-60 deg/min, a further increase in temperature up to 350-500 degrees. with a lesser rate of 2-10 deg/min, and in the third and final stage to increase the temperature of the tissue to 500-750 degrees. third, the average speed is from 5 to 40 deg/min When using this method the fabric of cellulose fibres (viscose). After continuous carbonization of the tissue in the chamber, which incidentally is removed outside the gas phase from recycled pulp, the result is a fabric of carbon fibers. A disadvantage of the known solutions can be seen in the limited use of treated tissue (cellulose or viscose), as well as the impossibility of additional properties, both decorative and has a number of technical characteristics.

The problem to which the present invention is directed, is to provide a process of tissue in a solution containing nanoparticles of carbon, and optionally enter the nanoparticles, such as nanoparticles of noble metals. In addition, the solution can also be injected nanoparticles of precious or semi-precious mineral is s.

Technical result - providing a decorative properties of the treated tissue and the expansion of their technical characteristics.

This technical result in the method of processing tissue, namely, that use a solution with nanoparticles of carbon, which put the fabric and exposed to ultrasound, and nanoparticles of noble metals and/or nanoparticles of precious or semi-precious minerals, and exercise microwave exposure and subsequent drying.

Furthermore, this invention possible special cases of the implementation or use a combination of traits, reflected in the independent claim are that:

- noble metal nanoparticles and/or nanoparticles of precious or semi-precious minerals added to the solution with nanoparticles of carbon, and high-impact exercise at the same time or after exposure to ultrasound;

- the processing of tissue in a solution with nanoparticles of noble metals and/or nanoparticles of precious or semi-precious minerals carried out separately and sequentially in time from the fabric treatment solution with carbon nanoparticles;

as noble metals are used, for example, nanoparticles of gold and/or silver and/or platinum;

as precious or semi-precious miner is fishing use, nanoparticles, for example, diamond, and/or ruby and/or sapphire, and/or malachite;

- use carbon nanoparticles with various modifications;

as a modification of the nanoparticles carbon use ball types;

as modifications of carbon particles using porous tubes;

as modifications of carbon particles using a nanoparticle;

- use different degree of porosity of the carbon nanoparticles;

additionally carry out laser treatment, which is performed by pulses of different duration and intensity over the entire surface of the treated tissue;

- to enhance the properties of the treated tissue, increasing the thickness and combination of properties after drying fabric from the previous processing is carried out it again or repeated handling.

The implementation of the method can be carried out on the installation shown in the drawing and containing the bath 1 with the cover 2, the outer shafts 3 and 4. In the bath 1 set inner shafts 5 and 6, as well as ultrasound unit 7, which, in the course of movement of the processed fabric is microwave installation 8. Over the bath 1 is installed laser apparatus 9 that is driven by the scan drive 10.

The treated fabric 11 from the drive (in the drawing not shown) with the outer shaft 3 is directed into the tub 1. Next TKA is ü 11 in the processing goes on ultrasonic 7 installation, microwave installation 8 along the inner shafts 5 and 6 and is directed to the outer shaft 4, which comes into the drying chamber (drawing does not depicted).

As the treated tissue can be used cotton, linen, wool, silk fabrics, both natural and artificial and synthetic fabrics, non-woven materials, which are preferably in the roll. The width of the tissue during processing in the tub 1 can vary from 0.1 to 1.3 meters Also can be processed cloths custom sizes.

Preparatory actions.

To handle choose the fabric. The stretch fabric 11 from the drive and from the shaft 3 is slid into the tub 1, performed along the shafts 5 and 6 and output shaft 7, and then is directed into the drying chamber, locking the fabric, for example, on tandem drum (in the drawing not shown).

Bath 1 filled with a solution of 12, which is based on pre-purified water or distilled water. The initial water temperature 20-25 grads In the solution 12 is injected carbon nanoparticles. The sizes of these nanoparticles and their structure is selected depending on the type of fabric 11, and also taking into account the desired technical result. The range of the nanoparticles is selected in the range from 10 to 200 nm.

Such dimensions provide, firstly, their uniform distribution over the volume of the solution 12 for the duration of the process, which also increases the action of the ultrasonic installation 7.

Secondly, is alsoe value is the ratio between the size of the cavities in the structure of the processed fabric 11 and the dimensions used in the solution of carbon particles. So, if the size of the cavities of the fabric 11 more sizes are used in the solution of carbon particles, in this case more reliable penetration of such nanoparticles in the fabric structure 11, which leads to increased adhesion of carbon particles with fabric 11.

Can also be used in various modifications of carbon particles cluster type with varying types of porosity. So as modification of carbon particles can be used, for example, ball types. They are used for fabrics with cavities "socket" type. This leads to a General enhancement of the strength characteristics of the tissue and, in particular, increased electrical conductivity, antibacterial and flame-resistant properties. As an example, the fabric of silk, for which it is advisable to use the minimum size of the nanoparticles of the above range.

When using fabrics with fiber structure applied nanostructures cylindrical form or a porous tube subnanomolar size. Treatment leads to the plexus of fibers 11 with elements of these nanostructures from the solution 12, which provides a larger gain strength characteristics of the fabric 11 and its fireproof properties. The operation of the ultrasonic installation 7 enhances the diffusion of nanostructures cylindrical form and the porous carbon tubes into the fabric 11, that increases the chaotic process plexus of fibers 11 and carbon nanotubes.

One of the main parameters affecting the properties of the fabric 11 is the concentration of carbon particles in solution. Increasing the concentration increases and the emergence of new properties of the treated tissue, for example, the adaptation of low-frequency electromagnetic waves and fields.

The range of concentration of carbon particles in a solution of 12 for specific types of processing tissue is selected in the range from 5 to 50 g/L. Power ultrasonic installation 7 is within 200-500 watts. Lower limits are used for plant tissues, and upper limits used for synthetic fabrics.

In addition to the nanoparticles of carbon in the solution 12 in the form of nanopowder in the solution 12 to impose an additional noble metal nanoparticles, also in the form of a nanopowder. They are made from gold, silver, platinum. The introduction of them into the base fabric 11 allows to obtain, in addition to decorative qualities, such as different colors - gold, Golden, green, silver, emerald, and colors, which depend primarily on the concentration of these particles in solution and combination of components. In addition, the fabric 11 new technical properties, such as, for example, the ability to screen high-frequency radiation. Also provide the receive bactericidal properties of the fabric 11. The concentration of the nanoparticles of noble metals is chosen in the range of 0.5-10 mg/l

The effect of microwave leads to heating of the nanoparticles of noble metals, which under the action of ULTRASONIC proplast itself a passage in the thickness of the cloth material 11 and more intensely embedded in its structure. Power microwave installation 8 in this case, choose the minimum and equal to 600 watts.

During processing, the temperature of the solution 12 will increase due to the operation of stations 7 and 8, which speeds up the process, but on the processing quality of the fabric 11 is not reflected. Evaporation of the solution 12 can be compensated in two ways: either by adding to the bath 1 corresponding volume of water and the necessary weight of nano-products, or by adding to the bath 1 ready solution of the required amount with the nano. Similarly, you can compensate for the drift of the solution 12 with the fabric 11 in the drying chamber.

Separately or in combination in the solution 12 can be entered nanoparticles of precious or semi-precious minerals. An example of such minerals: diamond, ruby, sapphire, malachite.

These nanoparticles when processing tissue 11 is also exposed to the ULTRASONIC source 7 and the microwave source 8. Power microwave source 8 for these nanoparticles increased to 900 watts, because these minerals are less conductive. These minerals embodied in the nanostructure and used in the solution 12 p is separately or in any combination, attach fabric 11 corresponding color and provide bright lighting effects.

The treated fabric 11 change not only decorative properties, such as, for example, diamond glitter cover, the play of light and rainbow patterns on the surface, but there are new specifications, for example, decreases thermal conductivity. When processing tissue 11, for example, nanoparticles of diamond, it has, in addition to decorative effect, seen in such as the piezoelectric effect. It occurs for the following reason: nanoparticles of diamond, located in the treated fabric 11, when the load is producing electrical charges.

It should be noted that the processing of the fabric 11 in the solution 12 with nanoparticles of noble metals and/or nanoparticles of precious or semi-precious minerals can be performed separately and sequentially in time from the processing of the fabric 11 in the solution 12 with nanoparticles of carbon.

For this purpose, the fabric 11 is treated in solution with nanoparticles of carbon, introducing a new tub with the prepared solution 12 with nanoparticles of noble metals and/or nanoparticles of precious or semi-precious minerals, with a corresponding concentration.

Additionally, during processing, it is possible to use laser treatment. This action is performed by the laser system 9, the driven scanning the respective drive 10 over the entire surface of the fabric 11. When this occurs, the strengthening of the action of the microwave setup 8 and formation of nanoparticles of various structures, such as layered. Such particles, settling in turn and penetrating into the fabric structure 11, create a layer by layer with the specified technical parameters, for example, with properties photoconductivity or quantizeimage effect.

The parameters of the laser system 9 is chosen based on the properties of the fabric 11, and the specific heat used in the solution of nanopowders. A laser device 9 can operate both in continuous and pulsed mode. The continuous mode is preferred for tissue from material of vegetable or animal origin, and pulse mode - for synthetic fabrics. The power of a laser system 9 in continuous mode up to 50 watts and a pulse of up to 1000 W at a pulse duration of 0.0001-0.001 in s and duty cycle 1:100-1:10000.

The control process is carried out at an intermediate stage, i.e. after the previous processing, and at the end of the whole process, after drying, the fabric 11. Inspection may be visual, in particular, with the help of optical instruments. This looks uniformity of the coating, filling the entire surface of the fabric applied nanostructures, color coating, compared with the standard table, classified the resulting color. Monitored and technology the economic characteristics: strength - on a tensile testing machine, thermal and antibacterial, electromagnetic and photometric characteristics examined on the respective stands and shrug their laboratory tests.

A laser device 9 operates in the mode of constant radiation power of 30 watts. Set the speed of the moving cloth 11 is 3-5 cm/sec. With the passage of cloth 11 ultrasonic installation 7 carbon nanoparticles and mineral oxide of titanium embedded in the fabric 11 and are evenly distributed in it.

After processing and drying conduct laboratory control. Inspection results: the rugged vodoprovodniy fabric. The last characteristic is ensured by the properties of titanium dioxide.

Example 4. Fabric: wool. The nanoparticles used in the solution 12: carbon and diamond. The concentration of diamond in a solution of 12 - 0.05-0.1 g/l, carbon 30-70 g/l Include ultrasonic installation of 7, its power up to 200 W, as the fabric 11 is more susceptible to diffusion due to its loose structure. Microwave installation 8 and the laser installation 9 is disabled.

The fabric 11 is moved with a speed of 1-4 cm/sec. With the passage of ultrasonic installation 7 it is embedded nanoparticles of carbon and diamond. Under the action of ultrasonic installation 7 the nanoparticles are evenly distributed in the structure of the wool fabric 11. After processing and drying conduct visual and technical control. Inspection results: the enhanced fabric with the surface, iridescent, changing the direction of light.

To enhance the properties of the treated fabric 11, increasing its thickness and combination of properties after drying fabric 11 from the previous processing is carried out again. It is also possible, and repeated the process.

The use of this method allows to obtain a fabric with decorative features and specifications.

Note here that vapors of said metals are deposited on the surface of polymer film in amount of 1014-1016 metal atoms per 1 cm2 of the surface. Then, polymer film containing deposited metal is melted, the melt being mixed and granulated. Note here that metal content in produced metal-containing nanocomposites is regulated by repeating deposition and melting and/or varying surface-to-area ratio in initial polymer film.

EFFECT: ruling out agglomeration of separate nanoparticles, uniform sizes and distribution of said particles, simplified procedure and ease of production.

SUBSTANCE: invention relates to powder metallurgy, particularly, to production of heat-resistant nanostructured structural material by granulation metallurgy. Proposed method comprises mixing components containing copper base and carbon nanotubes, a nanostructured material, and compacting produced mix at appropriate pressure and temperature. Prior to compacting, said mix is placed in capsule for mix to be compacted at 0.7-0.95 of copper base melting temperature and 1100-1500 atm for 2-5 hours. In mixing said component, they activated by straining in ball planet mill or by adding surfactants. Besides, prepared mix is subjected to pre-compaction at room temperature at 0.1-0.5% of modulus of elongation.

EFFECT: structural material with good soldering and welding properties and higher heat resistance.
