METHOD AND PRODUCTS FOR REALIZING DECORATIVE ELEMENTS ON A COLOURED FABRIC AND/OR ITEM OF APPAREL, AND A FABRIC OR ITEM OF APPAREL OBTAINABLE BY APPLYING SUCH A METHOD AND PRODUCTS DESCRIPTION
The object of the present invention is a method and a product for realizing decorative elements on a coloured fabric and/or item of apparel. The invention also refers to a fabric and an item of apparel obtainable by using the above method and products. This method and these products are particularly, yet not exclusively, applied in the jeans and denim fabric manufacturing branch and in the confection sector of items of apparel made from these fabrics.
It is known that in the mentioned sectors the jeans and denim fabrics and the items of. apparel confectioned from these fabrics are subjected to a plurality of chemical treatments for realizing decorative elements on their surface. In particular, decorative elements are known that essentially consist of a plurality of surface areas of the fabric and/or item of apparel that have been partially or wholly decoloured. The process known for setting up these decorative elements is described as follows. The method initially consists in a phase of applying to the surface of the fabric and/or the item of apparel a template fitted with a plurality of slits or openings which are in the overall defining a decorative pattern or a plurality of decorative patterns, such as for instance inscriptions, flowers etc. . The method then comprises an intermediate phase of decolouring, in order to decolour the surface of said fabric and/or item of apparel covered by such a template. The mentioned method then involves a final washing phase to eliminate the decolouring substances, which have been deposited on the fabric and/or the item of apparel in the previous treating phases, from the fabric and/or the item of apparel. According to this method, the decolouring affects the surface areas of the fabric and/or of the item of apparel accessible through the slits or openings of the template, in other words the areas not protected by the template. The fabric and/or the item of apparel thus obtained superficially
exhibits a plurality of decorative elements that reproduce the pattern employed.
The main drawback recognizable in this method consists in that the use of the decorative patterns allows realizing decorative elements or a plurality of decorative elements on fabrics and/or items of apparel that are standardized only.
A second drawback recognizable in this method consists in that the available patterns limit the type of decorative elements that can be produced.
A third drawback recognizable in this method consists in that the use of patterns makes executing the decorative elements a rather complex task.
The aim of this invention is to set up a method and products for realizing decorative elements on a fabric and/or on an item of apparel, and a fabric and item of apparel obtainable by the above method and products and able to solve the problems outlined above. Within this aim, an important object of the present invention is to set up a method that allows to personalize the decorative elements that can be produced on a fabric and/or item of apparel.
A further important object of the present invention is to set up a method that allows to execute a practically unlimited variety of decorative elements.
Not the iast object of the present invention is to set up a method for simple industrial implementation.
This aim and these and other objects that will become better apparent in the following, are achieved by a method and products for realizing decorative elements on a coloured fabric and/or item of apparel, as well as by a fabric and/or an item of apparel obtainable by such a method and products, according to the attached claims.
According to first features of the invention, the method essentially comprises the following phases: - An initial phase of realizing an adherent protective layer of the surface of the fabric and/or of the item of apparel;
A subsequent phase of rupturing said layer to create a plurality of rupturing lines in said layer, so as to define an overall pattern of a decorative element or of a plurality of decorative elements;
An intermediate stage of decolouring, to decolour the areas of said surface accessible through the rupturing lines;
A final washing phase to eliminate said layer from the fabric and/or from the item of apparel.
In this way, the appropriately decoloured areas define the decorative element or the plurality of decorative elements determined by the pattern. This solution thus allows realizing personalized fabrics and/or items of apparel characterized by a decorative element or by a plurality of decorative elements so as to constitute items of a unique form.
According to second features of the invention, this plurality of rupturing lines can be realized in a random fashion so as to impress the fabric with one random decorative element or a plurality of random decorative elements, or in a predefined way to impress the fabric with a geometric decorative element or a plurality of geometric decorative elements. This solution thus allows realizing a practically unlimited variety of decorative elements, so as to allow the creative fancy of the designer to express it freely. According to other features of the invention, the method is generally easily implemented in the fabric manufacturing and items of apparel confectioning branches, and in particular in the industry of producing jeans and denim fabrics and of confectioning items of apparel made from these fabrics. Further features and advantages of the invention will be better evident from the description of a method for realizing decorative elements on coloured fabrics and/or on items of apparel, of products applicable in executing such a method and of a fabric and/or an item of apparel realized according to this method and by the application of these products, as illustrated for indicative yet non limiting purposes in the attached drawings, wherein:
Figure 1 represents a detailed view of a first portion of a jeans fabric comprising a decorative surface element of a random type;
Figure 2 represents a detailed view of a second portion of jeans fabric comprising a surface decorative element of a geometric type. The method used for realizing decorative elements on a fabric or an item of apparel is described as follows. This method essentially comprises an initial phase of realizing a protective layer adherent to the surface of the fabric and/or the item of apparel and a subsequent phase of rupturing said layer to create a plurality of rupturing lines that define an overall pattern of a decorative element or of a plurality of decorative elements. The method further comprises an intermediate decolouring phase to decolour the areas of said surface accessible through the rupturing lines and a final washing phase to eliminate said layer from the fabric and/or the item of apparel. The appropriately decoloured zones mentioned above thus define the decorative element or the plurality of decorative elements determined by said pattern. In detail, this initial protective layer realizing phase comprises in a sequence: a phase of preparing a mixture of substances hardening to a solid state; a phase of heating said mixture up to its melting temperature, so as to obtain a molten mixture; a phase of applying said mixture to the surface in a molten state; and a phase of cooling the mixture down to room temperature to form the mentioned protective layer. The Applicant has appropriately verified that the melting temperature of the mixture of hardening substances is approximately equal to 70 0 C. At this temperature the mixture is ready for the phase of application, which preferably occurs by painting the surface of the fabric and/or of the item of apparel. The phase of rupturing the protective layer comprises, according to a first form of embodiment, an operation of rolling up said fabric and/or item of apparel and of pressing said fabric and/or item of apparel in a rolled-up condition. The rolling-up operation appropriately occurs in several rolling-up directions. This way of executing the rupturing phase determines a plurality of rupturing lines with a random distribution which lead to a random decorative element on the fabric and/or on the item of apparel, as shown in Figure 1. The phase of rupturing the protective layer
comprises, according to a second mode of execution, a plurality of incising operations of said layer. Said plurality of incising operations determines a plurality of rupturing lines with a predefined distribution, so as to determine a decorative geometric element or a plurality of decorative geometric elements on the fabric and/or on the item of apparel, as shown in Figure 2. The decolouring phase comprises in turn a phase of spraying a mixture of decolouring substances onto the surface of the fabric and/or of the item of apparel covered by said layer, a phase of penetrating said layer on the part of said mixture of decolouring substances through said rupturing lines, and a phase of absorbing of said mixture of decolouring substances on the part of the fabric and/or of the item of apparel.
The Applicant has advantageously provided for executing the absorption phase in a forced way, so as to highlight the effect generated by the decorative element or by the plurality of decorative elements, or in a natural way. The forced absorption phase involves the retention of the fabric and/or of the item of apparel in a heated environment for an absorption time suitable for accelerating the absorption of the decolouring substances on the part of the fabric and/or of the item of apparel. The heating environment is in this case heated to about 70/80 0 C, and the absorption time is of about 10 minutes. Between the mentioned decolouring and washing phase it is advantageously possible to perform a dyeing phase for the fabric and/or item of apparel, so as to dye the surface areas accessible through said rupturing lines. This makes it possible to achieve fabrics and/or items of apparel with coloured decorative elements and/or a plurality of coloured decorative elements. Finally, the washing phase comprises a first hot washing phase, a second hot washing phase and a final cold water rinsing phase. Said first washing phase is done in water treated with a first mixture of washing substances at a washing temperature of about 70 0 C for a washing time of about 10-15 minutes. The second washing operation is done in water treated with a second mixture of washing substances at a washing temperature of about 50 0 C for a washing time of about 5 minutes.
The products for executing the individual phases of the method are described in the following. The product for executing the realization phase of the layer essentially comprises a mixture of hardening substances preferably based on a plurality of hydrogenated fatty acids and alkylated polyglycolethers. Stearic acid and palmitic acid are preferred in the first case. The product for executing the decolouring phase comprises a mixture of decolouring substances that preferably consists in an aqueous 50% hypochlorite solution. The product for executing the dyeing phase comprises a mixture of organic pigments in an aqueous solution and of binders to bind said pigments at a low temperature, for instance an aqueous acrylic butadienic emulsion. The products for executing the washing phase comprise a mixture of first washing substances to perform the first washing operation and a mixture of second washing substances to perform the second washing operation. Said mixture of first washing substances preferably comprises complex salts and sodium salt of organic polymer, and said mixture of second washing substances preferably comprises alkylated polyglycolethers of fatty acids. Finally, the product for executing the colouring phase comprises organic pigments in an aqueous solution.
With reference to the Figures 1 and 2, the fabric or the item of apparel obtained by applying said method and the above products essentially comprises a uniform colouring area and decoloured/coloured areas defining a decorative element or a plurality of decorative elements. In particular, the decorative element of Figure 1 exhibits a "branched-out" appearance, while the decorative element of Figure 2 exhibits a "geometric" element resembling a grid.
It has in practice been found that the method, the products and the fabric and/or the item of apparel described above achieve their expected aim and objects. The method in fact allows personalizing the decorative elements that can be realized on a fabric and/or an item of apparel. The method also allows realizing a practically unlimited variety of decorative elements. Finally, the method appears to be easily implemented on an industrial scale.
The method, the products and the fabric as well as the item of apparel according to the invention are susceptible of numerous modifications and variants, all of which fall within the range of the same inventive concept.
In a practical embodiment, the materials employed, the shapes, the dimensions, the solution ratios, the temperatures and the executive details may differ from those indicated above but be technically equivalent to them, without thereby abandoning the scope of the invention.
