    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention recommends a dyeing or dyeing medium for textile dyeing and printing by applying dye materials of natural origin and a resin of recycled origin of post-consumed products, whose function is to fix the dye materials to the textile.
    [0007]
    [0008] The object of the invention is to offer a low environmental impact coloring medium, substantially reducing the contaminating residues that are produced in textile dyeing and pigmentation processes. Thus, the coloring medium of the present invention allows to achieve a stable and lasting fixation of the dyeing and textile printing.
    [0009]
    [0010] BACKGROUND OF THE INVENTION
    [0011]
    [0012] In the current state of the art, textile dyeing and printing processes of yarns, fabrics and garments among others are well known.
    [0013]
    [0014] The mentioned procedures are based on the impregnation of a textile with a solution or dispersion of a pigment, by means of a fixative that maintains the coloration and / or pigmentation of the textiles.
    [0015]
    [0016] Thus, during dyeing and printing, textiles have a certain rejection of the absorbed dye. This rejection is diminished by the pigments and fixatives used in the preparation of dyeing mixtures for dyeing and textile printing through different procedures such as textile dyeing by impregnation and depletion, or the method of stamping by means of equipment diverse.
    [0017] The pigments and fixatives currently used include toxic components and contaminants, such as acrylic resins from polymethylmethacrylate (PMMA).
    [0018]
    [0019] That is to say, traditional fixatives and mordants are toxic chemical components that have a negative environmental impact and generate wastewater flows with significant pollutant load and for emitting volatile organic compounds during use.
    [0020]
    [0021] The present invention offers an alternative solution to the use of toxic and contaminating materials in the coloring media applied in textile dyeing and printing processes, being a sustainable and innovative coloring medium.
    [0022]
    [0023] DESCRIPTION OF THE INVENTION
    [0024]
    [0025] The present invention recommends a medium or mixture of dyeing and textile printing of low environmental impact that incorporates at least one dye material of natural origin and a resin of recycled origin from the PVB (polyvinyl butadiene or butyral) allowing a solid fixation of coloring materials to textiles, such as threads, fabrics or garments and thus offering a sustainable and innovative coloring.
    [0026]
    [0027] The recycled PVB resin comes from materials that have been previously used for other purposes, specifically this resin comes from discarded glass or safety glass, thus passing the material back into the production cycle.
    [0028]
    [0029] The recycled PVB resin is preferably obtained as a powder or as a dispersion, allowing the dye material of natural origin to adhere more easily to textiles.
    [0030]
    [0031] On the other hand, the dye material of natural origin is a pigment of mineral origin or a dye.
    [0032]
    [0033] Additionally, the resin of recycled origin from the PVB has properties of greater interest than the virgin PVB resin for use in applications textiles
    [0034]
    [0035] In this sense, we must emphasize that the resin of recycled PVB origin has a lower glass transition temperature and a elongation of breakage greater than the virgin PVB resin.
    [0036]
    [0037] Therefore, the resin of recycled origin from the PVB, compared to the virgin PVB resin is elastic enough, offering a touch and fixing properties suitable for use in textile dyeing and printing processes.
    [0038]
    [0039] The properties associated with the resin of recycled origin from the PVB offer an advantageous behavior compared to the use of other synthetic fixatives, such as traditional acrylic resins. The following table shows the values determined for the recycled PVB resin and for the PMMA acrylic resin in order to support the advantageous behavior of the recycled PVB resin.
    [0040]
    [0041] Table 1: Properties of the recycled PVB resin and the PMMA acrylic resin.
    [0042]
    [0043]
    [0044]
    [0045]
    [0046] The resin of recycled origin from the PVB has a glass transition temperature between 15 ° C and 22 ° C - specifically 19.26 ° C - compared to the 100 ° C glass transition temperature of the PMMA. That is, the low glass transition temperature of the recycled PVB allows it to offer an elastic and flexible behavior, rather than the rigid and brittle behavior offered by the PMMA because of its high glass transition temperature.
    [0047]
    [0048] On the other hand, the resin of recycled origin from the PVB has an elongation at break of between 200 and 250% - specifically 230% - compared to low elongation at break (less than 40%) presented by the PMMA. Therefore, the elongation at break of the PVB Recycling is far superior to what PMMA experienced.
    [0049]
    [0050] Finally, from the parameters shown in the table, we observe that the recycled PVB facilitates the fixation of the coloring materials of natural origin due to the elongation of the rupture and the tensile strength it offers, thus allowing a wide durability of the textile dyeing despite the influence of external agents.
    [0051]
    [0052] For all the above, it is concluded that the recycled PVB resin has qualities that allow its use as a sustainable and innovative substitute for acrylic resins, such as PMMA.
    [0053]
    [0054] In this way, the coloring medium prepared using the recycled PVB resin offers an improved fixation for textile dyeing and printing, avoiding the use of toxic and contaminating coloring materials and fixatives, such as traditional synthetic fixatives.
    [0055]
    [0056] On the other hand, it should be noted that the mixture or dyeing dye and textile printing object of the present invention can be used in the following textile dyeing and printing processes.
    [0057]
    [0058] Specifically, the coloring medium developed by dyeing will be applied: of fabrics, in garment and dyeing in thread, as detailed below:
    [0059]
    [0060] - Fabric dyeing (flat, knit and non-woven):
    [0061] By impregnation or foulardado.
    [0062] Due to exhaustion in manipulation or Jigger (atmospheric / pressure).
    [0063] By exhaustion in jet (atmospheric / pressure).
    [0064] Due to excess exhaustion or overflow (atmospheric / pressure).
    [0065] - Tincture on garment:
    [0066] Tincture from exhaustion in "washing machine" or tumbler.
    [0067] - Dyeing in thread:
    [0068] For exhaustion in hank.
    [0069] By exhaustion in cone.
    [0070] By foulardado to the continuous one.
    [0071] Additionally, the coloring medium developed by stamping will be applied by: - Flat stamping equipment (lionesa).
    [0072] - Rotary stamping equipment.
    [0073] - Flat stamping equipment on table.
    [0074] - Digital stamping.
    [0075]
    [0076] Depending on the desired textile application, the coloring medium is prepared in the form of a bath, ink or coloring paste made in an aqueous medium in which the material of natural origin that will be fixed to the textile by means of the resin of recycled origin is incorporated from the PVB.
    [0077]
    [0078] Advantageously, the resin of recycled origin from the PVB offers a fixation of the pigments or dyes of natural origin to the very stable and durable textile, even to rub.
    [0079]
    [0080] In this sense, it has been proven that the fast washing and dry and wet rubs offered by textile dyes or prints obtained by using the coloring medium prepared with the resin of recycled origin from the PVB are excellent. This aspect is difficult to obtain if we use the natural dyes currently known
    [0081]
    [0082] In the case at hand, we understand the strength of the dye on the textile, the ability of the dye material of natural origin to remain fixed to the textile by means of the resin of recycled origin from the PVB when a certain external agent affects it.
    [0083]
    [0084] Next, the results of the fastnesses are exposed to washing and rubbing a dye on a 100% cotton fabric, using the dye material of natural origin fixed with the resin of recycled origin from the PVB.
    [0085]
    [0086] The 100% cotton fabric is subjected to two tests in which the solidity of the color of the mentioned fabric is determined in two different cases, namely: washing fastness and rub fastness, both dry and wet.
    [0087]
    [0088] In the tests the solidity for the discharge and for the degradation was determined. Where he degradation level is defined as the change in hue or intensity of the initial dye when an external agent affects it. On the other hand, the discharge is defined as the staining or dyeing intensity of a multi-fiber control when washed together with the colored tissue to be analyzed.
    [0089]
    [0090] The determination of wash fastness is based on the UNE-EN ISO 105-C08: 2010 standard. To do this, first, the level of color degradation is examined by household washing and commercial washing using a phosphate-free reference detergent that incorporates a low temperature bleach activator in order to test the initial dye.
    [0091]
    [0092] Secondly, the level of discharge in domestic and commercial laundering is examined, in which a multi-fiber token is introduced.
    [0093]
    [0094] The determination of rub fastness is based on the UNE-EN ISO 105-X 12: 2016 standard. Specifically, in the dry rub the degradation of the initial dye is tested first by rubbing with a dry white cotton baton.
    [0095]
    [0096] Secondly, the discharge of the color of the sampled tissue is tested by rubbing a dry white cotton baton.
    [0097]
    [0098] On the other hand, in wet scrubbing, the degradation of the initial dye is first tested by rubbing with a wet white cotton baton.
    [0099]
    [0100] Secondly, the discharge of the coloration of the tissue is tested by rubbing a damp white cotton baton.
    [0101]
    [0102] The results obtained are compared on a standardized gray scale, with values between 1 and 5, where the value of 1 corresponds to the minimum solidity and the value of 5 corresponds to maximum solidity.
    [0103]
    [0104] The results obtained from the tests carried out are very favorable since the analyzed samples of cotton textile dyeing with a dye of natural origin fixed with a recycled PVB resin offer maximum washing and dry rub fastness, obtaining in the four tests a rating of 5 out of 5. On the other hand, in the tests of wet rub fastness a rating of 4 out of 5 has been obtained, being also a data indicating a remarkable strength.
    [0105]
    [0106] Therefore, the fastnesses obtained that indicate the fixation on the 100% cotton fabric of the natural coloring matter by means of the PVB recycled resin are maximum.
    [0107]
    [0108] On the contrary, when performing analogous tests to determine the solidities of the natural coloring matter applied to textiles by means of acrylic resins, such as PMMA, we verify that the values obtained are below the results offered when using the recycled PVB resin as a fixative. .
    [0109]
    [0110] PREFERRED EMBODIMENT
    [0111]
    [0112] As detailed above, the coloring medium object of the invention can be embodied in a bath, an ink or a coloring paste.
    [0113]
    [0114] In a non-limiting embodiment of the invention, an example of preparing a coloring bath is detailed in this section.
    [0115]
    [0116] The dye bath is prepared from a solution of the fixative or binder obtained by dispersing the resin of recycled origin from the PVB, preferably in a concentration of between 5 and 250 g / L, in a liquid, preferably water.
    [0117]
    [0118] The dye material of natural origin, either a pigment of mineral origin or a dye, has a concentration of between 0.005 g / L and 50 g / L, which is added to the previously prepared dispersion of resin of recycled origin from the PVB. The chosen concentration of the pigment or dye, within the indicated range, allows to obtain the desired shades and intensities of color.
    [0119]
    [0120] Once the pigment or dye has been added to the previous dispersion of resin of recycled origin from the PVB, it is homogenized, before its application on the textile, in order to obtain a perfectly dispersed and homogeneous coloring bath.
    [0121] Finally, the coloring bath containing the resin of recycled origin from the PVB and the coloring material of natural origin is adsorbed by the textile by any of the applications mentioned in the previous section, such as dyeing of fabrics by impregnation.
