Description

PHOTOLUMINESCENT FABRIC AND METHOD OF MAKING THE PHOTOLUMINESCENT FABRIC
DESCRIPTION
Field of Invention
The invention relates to a photoluminescent fabric and a method of making a photoluminescent fabric, as generally used for making clothing that can capture and emit light to be always visible even in the dark for a given interval of time .
Background art
A number of fabrics are known in the art that can be used to make items of clothing that are visible in the dark, either by themselves or by being directly lit by an external light.
Typically, when these fabrics are required to be spontaneously photoluminescent, they are formed with self'photoluminescent filaments, which form the weave of the fabric that will be used to make items of clothing designed to be visible in the dark .
Other known photoluminescent fabrics are obtained by coating fluid photoluminescent materials on the weave of the fabrics, which are thus wetted thereby and acquire the photoluminescence of these impregnating materials .
Other visible fabrics for making clothing intended to be visible in the dark are made by covering one surface of the fabric with reflective portions of another material , as it happens when making work clothes for public workers, such as road workers, firefighters, health workers.
The above described prior art suffers from certain drawbacks .
A first drawback is that photoluminescent fabrics and items of clothing are obtained by first making photoluminescent yarns , which are later used to form the weave of the fabric, and provide limited photoluminescence, as photoluminescent yarns are woven with a multitude of other non-photoluminescent textile yarns .
A further drawback is that the photoluminescent yarns are required to have substantially the same flexibility and mechanical strength as normal textile yarns, to prevent excessive hardening or relaxation of the fabric or failure thereof as a result of mechanical stresses, such as systematic folding at portions of the item of clothing typically exposed thereto, such as jacket or vest sleeves or pant legs.
A further drawback typically concerning fabrics with strips or portions of other reflective materials applied thereto is that they cannot be visible in the dark unless they are lit by a light source, as they are not able to accumulate light by themselves .
Under certain conditions, this may cause late perception of the person that wears the item of clothing, and hence creates a safety hazard.
Disclosure of the invention
The invention has the object to improve the prior art.
A further object of the invention is to provide a photoluminescent fabric and a method of making a photoluminescent fabric, which provide totally photoluminescent clothing that can capture and accumulate light for a given interval of time and emit it in the dark.
A further object of the invention is to provide a photoluminescent fabric and a method of making a photoluminescent fabric that provide further products made of photoluminescent fabric, in addition to clothing.
In one aspect the invention relates to a photoluminescent fabric as defined by the features of claim 1.
In another aspect the invention relates to a method of making a photoluminescent fabric as defined by the features of claim 4.
The invention achieves the following advantages : obtaining a photoluminescent fabric that exhibits luminescence over its entire extent;
obtaining a photoluminescent fabric using synthetic fibers or natural fibers or a combination thereof.
Brief description of the drawings
Further characteristics and advantages of the invention will be more apparent upon reading of the detailed description of a preferred, non-exclusive embodiment of a photoluminescent fabric and an embodiment of a method of making a photoluminescent fabric, as shown as a non-limiting example in the annexed drawings , in which :
FIG. 1 is a sectional view of a portion of a photoluminescent fabric of the invention;
FIG. 2 is an enlarged view of a portion of the fabric of Figure 1, in a first schematic embodiment;
FIG. 3 is an enlarged view of a portion of the fabric of Figure 1, in a second schematic embodiment;
FIG. 4 is an enlarged view of a portion of the fabric of Figure 1 , in a third schematic embodiment .
Detailed description of a preferred embodiment
Referring now to the above mentioned figures , numeral 1 generally designates a photoluminescent fabric .
The photoluminescent fabric 1 comprises a first layer 2 of fabric, which may be selected from natural and synthetic fabrics , coated membranes , transparent and semitransparent extruded products, pierced or transparent non-woven fabrics , and a second layer 3 of fabric, also selected from natural and synthetic fabrics and also from non-woven fabrics, which are joined together in sandwich arrangement by joining means.4.
According to the invention, these joining means 4 are provided in the form of a layer of adhesive material which has been previously added with photoluminescent pigments 5 for imparting photoluminescence to this layer 4 of adhesive material that becomes visible, at least through the first layer 2.
The method of making the photoluminescent fabric 1 comprises a step of mixing luminescent pigments 5 in an adhesive material, a step of coating this adhesive material with the pigments 5 added thereto on at least one of the layers 2 or 3, and, after coating the layer 4 of adhesive material, a step of joining the first layer 2 to the second layer 3, e.g. using a calendar device, thereby obtaining a luminescent fabric that emits photoluminescence through at least the first layer 2 of fabric, which is designed to face outwards in any manufactured product.
Referring now to Figures 2 to 4, photoluminescence, schematically denoted by arrows "LL" , may be visible from the outside through the first layer 2 only, which in this case may be transparent (see Figure 3) or pierced (see Figure 2) as mentioned above, or the first layer 2 and the second layer 3 may be arranged to be both transparent (or both pierced, or one transparent and the other pierced) , for photoluminescence to be visible from both surfaces of the photoluminescent fabric 1.
The invention has been found to fulfill the intended objects.
The invention so conceived is susceptible to changes and variants within the inventive concept.
Also, all the details may be replaced by other technical equivalent elements .
In its practical implementation, any material, shape and size may be used as needed, without departure from the scope as defined by the following claims .
