Description

The present invention relates to a method for

  provide a manufactured textile product with luminous qualities

  its own, of permanent character and with multiple ranges, not only of luminosity but also of colors, with which one obtains fabrics comprising very characteristic, attractive effects, and, up to

a certain point, surprising.

  We have tried on numerous occasions and carried out technical studies and practical tests to provide fabrics with luminous decorative effects, but we have not so far found characteristics of-, natural luminosity and having permanent effects. has tried and produced serigraphic or other prints with special dyes, colored and / or phosphorescent pigments, but the maximum that has been obtained so far has been the obtaining of reflective effects

  that transform and reflect the luminous incidence

  but cannot be classified as characteristics

ticks of clean light.

  As a general rule, these applications are carried out with a thick textured paint or ink based on moistening pigments with solvents by simple mixing, ensuring that the incorporation of any other opaque pigment, or of any other element, cannot sift , obstruct or absorb the emission of light, which makes

  naturally decrease the phosphorescent luminosity.

  In reality we can describe very diverse variants for the preparation of paints or dyes, as well as their application, about the proportions of the phosphorescent pigments, solvents, elements

  to improve the suspension and homogeneous properties

  neisation of the inks, texture and perfection in the finish; but it all relates to the application on the

  fabric or plastic by printing, painting or the like

  re. The method according to the invention starts from a completely new and original principle for endowing the tissues with

  natural luminosity based on appropriately treated wires

  required which, by forming the texture of the fabric, give said fabric characteristic properties and allow multiple applications, some of them totally

unpredictable until now.

  The process according to the invention consists essentially-

  based on a preparation based on thermo-materials

  plastics, preferably of transparent type, such as polyvinyl chloride, and phosphorescent pigments,

  with or without addition of fluorine, all in proportions

  suitable for forming granules or particles which can be extruded at the appropriate temperature and pressure. By means of extrusion, a basic thread, natural or synthetic, of the above-mentioned preparation is covered which, once cooled, is vaporized to create a state of humidity and flexibility adapted to the texture of the fabric. obtained is characterized in that

that it is continuous and synthetic.

  As for the thermoplastic materials in which the pigments are incorporated, it is considered that they can be of any suitable type, such as methyl methacrylate, polystyrene, cellulose acetate and copolymers of vinyl and acetate.

polyvinyl chloride.

  The incorporation of pigments in plas-

  tick is preferably made at the time of manufacture,

  the powder being normally added to the plas-

  tick in its granular form The luminosity of the phosphorescent pigments is more stable when the physical effort to which they are subjected during their manufacturing process by incorporating them into the plastic material is less, since grinding should be avoided

  excessive by performing mixing and homogenization.

  So for example, in the manufacturing process

  tion, pigment and molding powder can be mixed

  dipped in a rubber mixing mill until the temperature rises to the softening point of the resin and, after cooling, the mixture is ground until granules having a size are obtained

particle size required.

  To concretize the details of the process according to the invention, it can be indicated, although only by way of example, that the core of the base thread, natural or synthetic, is subjected by extrusion to a thermoplastic covering based on a mixture of, for example, copolymers and polyvinyl chloride acetate with

  phosphorescent pigments, with or without fluorescent substance-

  according to a proportion of 5 to 10% of pigments for 90 to 95% of thermoplastic mass, which can range in extreme cases up to 70% of pigments for 30% of

  thermoplastic with all intermediate proportions

  possible, always within the permissible limits

  for adequate physical properties, resistance

  tance and plasticity to extrude said mixture and

  carry out the thermoplastic covering of the base wire.

  The pigments to be mixed can be only phosphorescent to obtain only luminosity or else mixed, in greater or lesser proportion, with coloring fluorescent elements to obtain

  color light effects, usually in pro-

  reduced portions of fluoride dye compared to

  phosphoric material, for example 10% So that the information

  dyes corporation is not detrimental to the brightness of the phosphor pigments, it should be noted that said dyes will be suitable for the brightness

emitted by said pigments.

  When the continuous wire is obtained by extrusion, in a size suitable for the texture to be produced, for example between 0.2 mm and 3 mm in diameter, the wire is vaporized at a temperature of the order of at 70 '' to obtain a certain softening of the thread and we proceed, while the thread is wet, to the manufacture of the desired fabric in which are incorporated in more or less quantity of threads of this nature The rest of the threads of the fabric to be manufactured are suitable the use of this fabric, which may be made of natural or synthetic fibers.

  The fabrics obtained by the process according to the invention

  tion possess extraordinary luminous effects, with multiple possibilities of variations and effects, so that vast possibilities open to the application of said fabrics obtained, not only by their decorative effect and shine in the confection and coatings , but also for their varied applications, for example in the

  photography, signage and imaginary achievements

native and fancy.
