Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the use of self-luminescent materials that are permanent and have multiple ranges, i.e. not only luminosity but also color.
tles) to textile articles (by means of which fabrics are obtained which exhibit surprising effects to a degree that are very distinctive and attractive).

Although many attempts have been made and technical research and practical tests have been carried out to impart luminous decorative effects to fabrics, until now it has not been possible to find suitable luminance characteristics and Characteristics of permanence of effect have not been achieved. Silk-screening and other printing methods with special dyes, colored and/or luminescent pigments have been tried;
However, the maximum that has been achieved so far is to obtain a colored reflective effect that converts and reflects the incident light beam, which cannot be described as self-luminosity properties.

In general, these applications may involve the incorporation of other opaque pigments or other elements to suppress, block, or absorb the original emission that would naturally result in a reduction in the luminance of the emitted light! To avoid scratches, coarse texture paints or dyes are made based on wetting the pigment with a solvent by conventional mixing.

In fact, there are many variations on paint or dye formulations.
! and in their applications @ the proportion of elements that improve the suspension and homogenization of the original pigments, solvents, dyestuffs, texture and finish quality could be described. But all this is printed, printed (impress)
ion), coating, etc. onto fabric or plastic materials.

The method of the invention starts from a completely new and original principle of imparting to fabrics their own luminosity. In the method of the invention, starting from suitably treated filaments which impart the same characteristic properties during the formation of textures, many applications, some of which were hitherto completely unforeseen, are possible. let

The method of the invention preferably consists of a transparent 8AW thermal '5'
It consists of starting from an IA product based on a Jvti material, for example PVC, formulated with luminescent pigments, with or without addition of fluorine. All ingredients are in suitable amounts to prepare a paste that can be extruded at a suitable temperature and pressure.

By extrusion, natural or synthetic basic yarns (b
aaic yarn) is coated with the above preparation.

Once cooled, the yarn is steamed
It imparts moisture and flexibility suitable for the intended texture of the fabric. The obtained yarn is continuously synthesized.
It has the characteristics of

The thermoplastic material with which the pigment is incorporated includes any suitable type, such as methyl methacrylate, polystyrene, cellulose chloride, and vinyl chloride.
There is a vinyl acetate copolymer.

Incorporation of pigments into plastics is preferably carried out during manufacture. Powders are usually added to pasty plastics. physical effort
The luminosity of the luminescent pigment will be even more stable if it is smaller when incorporated into the plastic and when applied to the pigment in the manufacturing process. For this reason, excessive grinding should be avoided during mixing and homogenization.

Thus, for example, pigment and molding powder can be mixed in a rubber layer in a manufacturing process until the temperature reaches the softening point of the resin, and after the mixture has cooled, the desired paste particles can be mixed. Grind to size.

In detailing the process of the present invention, it will be mentioned, by way of example only, that the core material of the basic yarn, natural or synthetic, such as vinyl chloride-vinyl acetate copolymer, luminescent pigments, and whether or not it is blended with It should be pointed out that thermoplastic coatings based on fluorescent mixtures are applied by extrusion.

1lII starting from 5-101 g of pigment and 95-90% of thermoplastic, in extreme cases 70% of pigment.
suitable physical properties, resistance and plasticity (within acceptable limits) during extrusion of the thermoplastic coating of the basic yarn and said mixture.

Mix well! The pigment can be a luminescent pigment alone, to obtain luminosity only, or a large or small amount of a colored fluorescent element, generally a small amount in conjunction with a phosphor substance, for example 1 to 1, to obtain a luminescent coloring effect. It can be mixed with 7 parts of IO.

In order to ensure that the formulation of the pigments does not suppress the luminosity of the phosphate pigments, it will be necessary to ensure that the latter are suitable for the luminosity emitted by them.

suitable size for the texture to be produced by extrusion,
After obtaining a continuous yarn, for example with a diameter of 0.2 mm to 0.3 rm+, the yarn is steamed at a temperature of 40 to 70 υ, which achieves some softening of the yarn, and the production of the desired yarn proceeds in wet conditions. , various amounts of such yarns are incorporated into the desired yarn. The rest of the yarns of the fabric to be produced are suitable for the above-mentioned applications and can be made of natural or synthetic fibers.

The fabrics obtained by the method of the present invention exhibit a remarkable luminous effect, have many varieties and effects, and are used not only for their decorative and attractive effects in the Higan ware and upholstery industry. Rather, it opens up a wide field of application of the fabrics obtained, for example for various applications in photography, signboards and creative and creative works.
