The present invention relates to fabrics or other textile products, including "educate"fiber, and the product made from this textile product and provided with a light source, running on electric batteries, which can be placed in convenient for the product pocket.

The invention also concerns the method for industrial production of such fabric using a conventional loom.

In this document the term "lit fiber" denotes a light path formed by the elementary fibers and/or optical fibers in a plastic material, for example: emission spectra obtained for pure (polymethylmethacrylat), PEA (politicalit), REM (polimetilmetakrilat), emission spectra obtained for pure/REM (polymethyl/polymethylacrylate), PC (polycarbonate), PS (polystyrene) and other

In the present description fabrics, containing light emitting fiber, it is already known, for example, from U.S. patent No. 4234907, however, because of the impossibility of manufacturing fabrics with such characteristics of their industrial production to date not implemented.

In the tissue according to the mentioned patent, the use of optical fiber illuminated at one end by a light source and provided with several slits in the outer shell, penetrating to the heart, allowing the light to emanate from the optical fiber, thereby giving the fabric I desired illuminating effect.

Unfortunately, the fabric described in U.S. patent No. 4234907, has several drawbacks:

The first drawback is that a large part of the light reaching the first slits in optical fibers, scatters, which does not allow light to reach the more remote slots without the use of a very powerful, consuming large amounts of energy and is characterized by large interference light sources.

The second drawback and, apparently, the most serious is that all these cuts weaken the fibers, making impossible the implementation of textile weaves and further technological operations (washing, friction, and other).

The third disadvantage is that in order to collect the illuminated fiber, it is necessary to make the fabric, a considerable part of the length of the fibers which comes out from the tissue, so that these fibers can be gathered into bundles and connect with the light source. However, the paper does not describe how to obtain the desired result suitable for industrial production method.

It is well known that the "normal" optical fiber used in U.S. patent No. 4234907 consist of "core" and "shell", the refractive index of which is lower than that of the core, in order to get the internal mirror effect, defines rasprostranennye from one end of the fiber to the other, without scattering it in the intermediate areas.

In GB-A-2305848 described to provide a visual alarm, including fabric, consisting of many strands, consisting of optical fibers, at least part of which is modified in such a way that they reject light outside from the sides of the threads.

The first aim of the invention is the creation of fabrics, including "educate fiber", and articles made from such fabrics and is suitable for easy and efficient industrial production.

In particular, products that can be manufactured from a fabric of the present invention, the following:

- articles of apparel and shoes (pants, jackets, skirts, overcoats, raincoats, capes, shirts, sportswear, shoes and other);

- sporting goods;

- accessories (bags, hats, ties, belts, wallets, gloves, umbrellas, etc.);

items for the house (curtains, tents, carpets carpet, cushion, pillows, blankets) and car (upholstery);

- the subject security (form for officers and employees of the rescue services, clothing for employees of technical services, safety signals for vehicles, tents for trucks, capes for hire, the signal strip and the like).

The second objective of the invention is to create industrial-effective method of manufacturing such fabrics.

These goals are achieved p is the creation of the fabric, made of it products and using industrial methods of manufacturing such fabrics, as specified in the independent items of the following claims.

In particular, in accordance with this invention, the desired effect of light scattering inside the product obtained by:

a) light optical fiber and the use of modifications of the surface of the fibers, which consists in changing their structure and application of some other operations (abrasion, crazing, scratches, folds on the surface) to cause local changes of the refractive index and to make possible a partial diffusion of the transmitted light;

b) adding alloying elements, disintegrating in the fiber and is capable of absorbing light within the fiber and re-emit it at an angle diffusion 360° (optical waveguides sparkling and/or iridescent light), so that the light falls at least partially at an angle that is different from the critical angle and therefore may go out;

in a corresponding modification of the refractive index of the sheath fibers in relation to this indicator core optical fibers so as to diffuse the light along the length of the fibers, which must be lit to change the portion of light that is reflected by the shell in the core.

Display the spruce of refraction is selected depending on the function of the product, which claim to produce from this fabric, the length of the fibers, subject coverage, and the characteristics of the light source.

In accordance with the following aspect of the invention, the refractive index of lit fibers can be easily changed by means of mechanical processing of tissue, such as brushing or sandpaper, or treated with chemicals, such as aromatic and aliphatic hydrocarbons; organic acids, aliphatic alcohol; ketones; aldehydes; aromatic and aliphatic chlorine derivatives; aromatic and aliphatic amines; amides; aromatic and aliphatic esters.

A suitable modification of the membrane fibers can be obtained by treating the tissue with a laser beam of appropriate power, capable of destroying a localized part of the membrane fibers without damaging the rest of the fibers.

So get lit fiber, which is essentially different than conventional optical fibers.

The advantages of this invention are evident from the following description and from the accompanying drawings given as a non limiting the scope of invention examples:

Figure 1 - example of a woven weave fabrics according to this invention;

Figure 2 - scheme of articles made from such fabrics;

Figure 3 - scheme of connection is through the power source from the light emitting fiber products made from fabrics according to the present invention;

Figa-4C - further stage of manufacture of the piece of jewelry according to the present invention;

5 is a diagram of another embodiment of a textile product according to the present invention, in which light-emitting fibers are in the form of threads weave fabric.

As shown in the drawings, in a preferred embodiment of the invention, the product according to the present invention consists of a fabric 1, in which the set of warp threads consist of scintillating fibers 2 arranged along the width of the weave 3 tissue.

As shown in the diagram woven weave in figure 1, the warp threads only fiber 2 is not twisted appropriate number m1 of 3 threads weave. Depending on the given number m1 threads loose weave the specified length of fiber 2 should be empty.

An advantage of the invention is the fact that thus you can define the length of the illuminated threads that should be collected into bundles and fasten at one end, so you can light up the light source, which is described in more detail below.

Another advantage is that the rest of the warp threads in the usual manner interwoven threads of the weave, so that the part 6 of the fabric with loose fibers 2, not spliced, and held the underlying part of the fabric, and it can bend and sew around the beam is somemuch fibers, as shown in figa-4C.

The resulting piece of fabric consists of part 5, in which the illuminated fiber 2 is woven in the usual way, and at least a second portion 6, having at least one bent section 8, which may be located the beam illuminated fibers 2.

As shown in figure 2, the product according to the present invention is made from a piece of fabric obtained as described above.

The end of the beam 7, leaving bent slice 8, seal metal ring 9 or other equivalent element, after which the fiber is cut (an angle of about 90° with respect to their axis)to improve the optical connection.

From the free end of the ring 9 is inserted light-emitting diode (LED) and tightly fix it so happened his optical connection with the ends of the fibers 2.

Electrical cable 11 is connected to the terminals of the diode (preferably welded) so that he spoke of them.

Preferably, the electrical connection 13 is protected by a cap 12 with polymeric filling to protect the connection from possible damage during use of the garment by the user.

In figures 4A-4C schematically shows the first phase of the manufacture of cloth with the connection beams free of fibers 2 (figa), the location of the beam along the edge of TKA is the second part of the product (fig.4b) and performing the bent cut to secure bundles of fibers (figs).

In a preferred variant of the invention, the illuminated fiber according to the present invention consists of a polymer optical fibers with chemical additives, also called scintillating fibers.

Components of the additives are, for example, from aromatic polycyclic organic molecules, whether or not containing quinone, amine, cyanine, asalnya groups that are present in the following compounds:

POLYPHENYLENE CONNECTION

Methyl-para-terphenyl(DMT)
Para-terphenyl(RTR)
Tetramethyl-para-quaterphenyl(TMQ)
Dimethyl-para-quaterphenyl(By bmq Wednesday)

and other

OXAZOLONE CONNECTION

Diphenylbutylpiperidines(BUTYL-PBD)
Diphenylquinoxaline(PBD)
Diphenyloxazole(PPO)

and other

COUMARIN COMPOUNDS

Hydroxymethylcytosine

Dimethylaminocarbonylmethyl

Benzothiazolylsulfenamide

and other

RODNIKOVYE CONNECTION

Diethylenetriaminepenta acid

Ester ethyl and ethylenediaminetetra-N-Xanten-benzoic acid

An advantage of the invention is that scintillating fibers capable of receiving light from the light source located at the end of the fiber, and the light that is widespread in the environment, through an intermediate twisted portion of the fibers.

Depending on the additives used, the fibers emit light with a wavelength of preferably from 400 to 700 nm, and more.

Another advantage of the use of scintillating fibers is that they can transmit to their ends of the light taken along their entire length.

Thus, during exposure of tissue to natural or artificial light, one or more light emitting diodes located at the ends of the fibers receive light passing through the fiber, and generate an electrical voltage. This voltage is fed to the DC-to-DC and used to charge the batteries.

Conveniently, these batteries can be the same as those used for illumination fibers.

The advantage is that when the fibers RUB or scratch", you get, as described above, the surface modification of the fibers, which allows you to increase the amount emitted in these places of light that allows you to "draw" the shape onto the fabric, using a small stick, stone, or other tools

Figure 3 schematically shows a few diodes 10 are located in parallel (you can use any combination of parallel and serial arrangement of the diodes 10 and connected by means of electrical cables 11 to the inverter 14 DC, powered by electric batteries 15, which may be replaceable or rechargeable type.

Preferably, the Converter and the battery is packaged in a common housing to reduce the overall size.

Depending on the type of product and the desired aesthetic effect for the manufacture of products you can use one or more pieces of the illuminated tissue.

In any case, it is possible to make pieces of fabric from the free length of the illuminated fibers are wide enough to connect all the beams from the same light source.

Preferably, the housing of the battery and the Converter DC was placed in a suitable pocket on the product, for example, at the waist of the trousers.

Alternatively, you can order from items left only the cables 11, ready for connection with an external power source.

In accordance with the invention description of the method of manufacturing the above fabric is provided below.

As shown in figure 1, on a conventional loom (figure not shown) is the number "n" of the warp(black lines in the figure), which is intertwined with ProBook threads 3 weave (white lines in figure 1), to obtain a continuous piece of fabric the desired length.

Many warp threads consist of fibers f (for clarity the figure shows only one fiber with respect to the weave, preferably one of the four pillars and one of the twelve, even if there are other relationships weave, make up one of the one or one of any other number.

In accordance with the position f of the fiber 2, the loom, which, preferably, is a machine with electronic control, is configured so that galeva healds consistent with the fibers 2, raised to the fiber 2 was released only m1 of ProBook threads weave and remained free from fabric 1, which preserves the continuity of tissue.

After execution of m1 ProBook machine set to maintain normal condition and again twist fiber 2 threads weave for the number of ProBook constituting m2, corresponding to the desired length made of fabric.

The advantage of this method is that changing the number m1, you can easily change the length of the free portion of the fiber 2, which allows to obtain beams illuminated fibers necessary for the manufacture of this product length.

For example, if for manufacturing the compliance of the product must have a length of free fibers 50 cm, during the textile should have a length of 1 m lost weave to get two useful pieces of fabric by cutting it in the middle of the height of the "lost" weave.

In accordance with this invention, if during textile covered fiber 2 behave differently than other warp threads (for example, because of different flexibility or different mechanical properties), you can be provided with some device to control the mechanical tension of the supplied fibers to prevent any problems loom during manufacture of the fabric.

For example, these devices for control of mechanical tension may consist of ordinary or additional Navoi for the supply of the power supply of the illuminating fibers, rotating under the control of independent engine with electronic and/or mechanical control mechanical strain.

Figure 5 shows a half-finished product consisting of a piece of 16 fabric according to the present invention, in which the illuminated fibers 2 are in the form of threads of the weave.

In this case, between the fibers 2 may be only a selected number of warp threads so as to have a certain length portion of the fibers 2 can stay free from the cloth.

The advantage is that these free the part can be located at the ends of the fabric (part P1 figure 5), and in any intermediate position (part P2 figure 5).

Mention should be made of this advantage, that every fiber 2 may be located at various positions in its woven into the fabric and in a separate piece of fabric, which in turn allows to obtain essentially any patterns or designs by combining the desired allocation of parts of the illuminated fibers protruding from the fabric.

More detail on figure 5 schematically shows a piece of fabric made of yarns W basis, the threads T of the weave and the illuminated fibers 2.

The advantage is that as a result of this invention, the piece 16 of the fabric can be cut with a given height H, and the free ends of the fibers 2 can be collected in bundles so they can be easily connected to the source light LS when this piece of fabric will be used for the manufacture of the final product.

In accordance with another advantage of the present invention, at least part of the fibers 2 are not located adjacent to each other, so that the portion 17 of the tissue lying under the free parts of the fibers 2 can essentially be continuous and can be, for example, as a protective layer during processing of the same piece 16 of the fabric.
