Definitions
- the present invention relates to a product for washing and simultaneously capturing colour molecules dispersed in the washing-machine wash waters; in particular it refers to a textile patch (woven and/or non-woven fabric) which has the function of supplying the laundry detergent and of attracting the dye molecules, sequestering them from the wash waters.
- a textile patch woven and/or non-woven fabric
- the problem referred to is of a general character and is known to whoever is involved in washing ordinary coloured items of clothing, both by hand and in the washing machine.
- washing coloured fabrics is often more problematic, especially in warm water (for example at temperatures above 30°C), because it often leads to the dissolution of colours in the wash waters, which hence take on a different colour from the usual clear one.
- An issue is that this loss of dye does not end exclusively in the wash waters and does not only lead to progressive discoloration of the fabric, but in turn leads to the partial dying of other fabrics immersed in the same bath.
- a solution which has been proposed to be able to wash together different-coloured items of clothing without the problems set forth above consists of patch-like supports to which a resin is variously applied, capable of sequestering the dye molecules from the wash waters.
- EP 2 447 412 in the name of Orlandi SpA deals with the problem of avoiding damages to items of clothing from colours coming from other items of clothing and present in the wash waters with a support of textile material, on which a polyamide cationic resin is applied, comprising a copolymer of adipic acid and cloromethyloxythane, diethylenetriamine and epichlorohydrin.
- a polyamide cationic resin comprising a copolymer of adipic acid and cloromethyloxythane, diethylenetriamine and epichlorohydrin.
- the opportunity of integrating such application with the addition of a water softener is also provided, so as to reduce the risk of scale deposits in the washing machine, which deposits may damage it over time.
- Dye removal occurs due to the fact that the dyes which enter into solution during the wash show a greater affinity for the agents present on the support than for the other items of clothing which are being washed: hence, the support according to this known technique sequesters the dye molecules before they reach the other laundry.
- the additive employed for capturing the colour does not dissolve in the wash waters and remains anchored to the support which becomes coloured.
- the number of fabric support pieces to be employed in the single wash varies depending on the type and weight of the load which is to be washed.
- This system performs at the same time its own colour-capturing and anti-scale function. However, it requires a certain capacity for the adjustment of the number of support pieces to be used, an incorrect assessment of such number de facto invalidating the usefulness of the product and an excessive use being polluting for the environment. Moreover, the use of a fabric softener and of a detergent is still required, so that a dosing ability for three different products must be acquired.
- WO2007/088149 describes a proceeding for applying to a textile support a cationic polymer and an acrylic resin which acts synergistically with the polymer for maintaining the dye molecules dispersed and for avoiding that the same adhere again to the fabrics.
- the acrylic resin is applied by printing on the support, using a paste.
- cationic polymer epichlorohydrin-imidazole is employed.
- acrylic resin a resin obtained by copolymerising acrylic acid and/or methacrylic acid and a monomer containing a strongly acidic group, such as a sulphonic group, is generally used.
- WO2009/062865 describes a textile patch made of non-woven fabric (TNT), imbibed with an acrylic polymer, an anionic or cationic surfactant, a mixture of polyvinylpyrrolidone-covinyl-imidazole, an epichlorohydrine polymer, clay particles containing ethoxylated alcohols and ethylene oxide.
- TNT non-woven fabric
- the textile support allows to combine in itself both the colour-sequestering and the deterging functions.
- the embedded product used is a rather complex mixture and is relatively expensive; moreover, it ends up discharging clay into the environment.
- clay could also accumulate in the washing machine, causing problems not unlike those usually caused by scale.
- the complexity of the mixture clearly shows the difficulty which must be faced to obtain a support which allows both to wash and to sequester excess colours.
- the problem at the basis of the invention is to provide a textile support with the following features:
- a support for capturing colour molecules dissolved in the wash waters in the washing machine, consisting of a patch to which a cationic resin and an acrylic polymer are applied, wherein a water-based detergent is also applied to said support, consisting of vegetable extracts, water-soluble and with a neutral pH.
- the present invention also refers to a process for the industrial production of such a support which provides the following steps: a) application by "foulard” impregnation of a patch with an acrylic polymer; b) application by “foulard” impregnation of the patch coming out of step a) with a cationic resin; and c) application by "foulard” impregnation of the patch coming out of step b) with a water-based detergent consisting of vegetable extracts, water-soluble and with a neutral pH.
- a support for a colour-catching product to be used in particular in a washing machine, consists, in a way known per se, of a handkerchief or patch imbibed - according to the way illustrated further on - with a cationic resin and an acrylic polymer.
- the non-woven fabric may be obtained by needle punching or, more preferably, by the spunlace method, that is by interlacing with water jets and without further chemical treatments (with a smooth or "perforated" surface appearance of the material, that is, characterised by a continuous series of small holes obtained by water microjets). It appears very pleasant, soft, light, it can be easily draped. Moreover, it is highly resistant and elastic and, not having undergone further chemical treatments, it is extremely pure and does not bring foreign agents into the wash solutions.
- An advantageous alternative consists of a non-woven fabric obtained with bamboo fibres, which is completely natural - with guessable disposal advantages - and provided with particularly welcome bacteriostatic features.
- the support size is not critical and can be chosen depending on requirements (evidently the wider the surface, the more sequestering product and detergent can be introduced into the wash with a single support).
- a number of supports with mutually different dimensions may also be manufactured, to be sold by dirt categories and load categories to be treated.
- cationic resins resins based on polyamine-epichlorphydrin, adipic acid/epoxypropyl diethylenetriamine copolymer, polymer of propenoic acid or ethyl ester with 1-ethinylpyrrolidone or vinylimidazole-based copolymer are preferably used.
- an acrylic-vinyl copolymer is preferably used, for example the product marketed under the name Appretan ® .
- a water-based detergent comprising only vegetable extracts, water-soluble and with a neutral pH.
- Such detergent in particular, is devoid of oxidants and enzymes, which implies enormous advantages for environmental protection.
- This specific choice is innovative since this detergent, unlike the ones known in the prior art, does not dissolve the two polymer components: by doing so, only the acrylic polymer and the detergent will enter into solution, upon washing, to the benefit of the effectiveness of this product.
- the detergent comprises vegetable extracts, non-ionic surfactants (in amounts below 5% by weight, preferably below 1% by weight) and possibly fragrances.
- the vegetable extracts are water extracts and may contain: Aloe vera, peppermint, rosemary, sage, lavender, marigold, limetree, Valeriana officinalis and/or witch hazel (amamelide).
- An example of detergent which has proven particularly effective has the following formulation: Ingredients (substances) INCI name CAS no. Level % Aqua Aqua 7732-18-5 A 100 Dimethyl glutarate Dimethyl glutarate 1119-40-0 ⁇ 5 - ⁇ 10 % Dimethyl succinate Dimethyl succinate 106-65-0 ⁇ 1 - ⁇ 5 % Dimethyl adipate Dimethyl adipate 627-93-0 ⁇ 1 - ⁇ 5 % Biodac 2-32 (non ionic surfactant) 68154-97-2 ⁇ 1 - ⁇ 5 % Dacol MLS-20 (non ionic surfactant) 9005-64-5 ⁇ 1 - ⁇ 5 % Extract of Aloe Vera Aloe Vera, extract 85507-69-3 ⁇ 0.1 - ⁇ 1 % Argan, Oil Argan, oil 223747-87-3 ⁇ 0.1 - ⁇ 1% Extract of Rosemary Rosemary, extract 84604-14-8 ⁇ 0.1 - ⁇ 1 % Extract of Sage Sage
- additives may also be applied onto the support, such as fragrances, sequestering agents, softeners, optic whiteners. Some of them may be applied by paste printing methods.
- the support according to the present invention may be accomplished as follows.
- the patch base is prepared in the desired size and weight, of course with a size suited to the industrial process, for example a canvas of 300 cm width and indefinite length, which will be subsequently cut to measure.
- the weight of a viscose-based non-woven fabric varies from 40 to 100 g/m 2 , and is preferably of 80 g/m 2 .
- the different products are applied one each, through a "foulard" application process and causing the support to pass in sequence through three stable baths for the three products.
- This way is the one which has proven functional for the specific products to be applied, which do not negatively affect each other and which perfectly adhere to the product.
- the "foulard" impregnation in stenter of the acrylic copolymer takes place.
- the drying temperature following impregnation is of about 170°C.
- 3-10 g/m 2 are applied.
- it is proceeded to foulard impregnation with detergent in the amount of at least 20-40 g/m 2 and drying at about 120°C.
- the product undergoes a weight increase of about 30-65 g/m 2 of active product only. Any other additives may be added by printing subsequently.
- the first impregnation with the acrylic copolymer and subsequent drying imparts to the support also wash-resistance, so that the fabric patch does not get torn to pieces in the washing machine.
- the foulard application provides that the support (to then be cut into patches) is immersed in the impregnation solution and is then caused to pass through two cylinders, one of which pushes onto the other in an adjustable manner, obtaining the squeezing of the excess liquid.
- the application may occur in any known manner, the application by foulard impregnation is preferable, since it allows an optimal distribution of the imbibing material, a greater absorption of the solution by the support, without implying a useless increase of the product to be applied.
- the product of the invention is produced by a single step of foulard impregnation.
- Fig. 1 shows evidence of some comparison tests on the product according to the invention and on a prior-art product.
- the greater absorption capacity of the detergent on the substrate in the presence of the treatment according to the invention compared to a standard product (sample C) must be underlined.
- This last aspect shows a peculiarity of the present invention, deriving from the careful choice and combination of products with which the fabric is imbibed.
- the tests have been carried out selecting a representative sample of fabric with size 15.5 cm x 19.5 cm on which a dying solution has been poured (standard dying agent Hispamin 10BS dissolved in water) and then closed in a container by agitation for 60 seconds. Once the fabric has been removed, the liquid has been left to decanter in a container identical to the ones used for standard solutions and then the colour thereof has been compared against standard solutions. A visual comparison has then been recorded as well as an instrumental colorimetric assessment.
- results of the transmittance and visual analysis (according to the SDLTM8 method) reported in the table represent the average value detected by the tests carried out on 5 samples for each type of detergent.
- a greater transmission % shows greater clearness of the released water; the clearer the released water, the greater the colour captured by the fabric.
- the aspect relating to processability is very important: the lower viscosity of the ER detergent allows an optimal processing of the fabric during the impregnation step, while it was possible to detect that the other detergents, being of a higher viscosity, cause product processability problems during this step.
- the operation of the product according to the invention is simple but highly effective.
- the support of the invention in the form of a patch, is inserted in a dry status into the washing machine, together with the laundry to be washed, without adding any other detergent in the machine.
- the (hot or cold) water enters the basket and begins to dissolve the detergent and the particles of acrylic copolymer.
- the choice of the particular detergent according to the present invention causes said detergent, unlike all other detergents, not to dissolve the cationic resin, so that said resin can continue to sequester the colour molecules which may be found in the wash water, capturing them before they are absorbed or adsorbed on the fabric of the other items of clothing, often of a different colour.
- the cationic resins will have absorbed part of the colour, making evident the effectiveness of the product.
- the dispersion of the copolymer, which has dissolved in the wash water, will also have performed a function of colour attractor, precipitating and then being disposed of with the drain waters.
- the synergy between the two resins is then particularly effective both in preventing the colouring of the items of clothing, and in making evident the absorbing function on the colour-catching patch.
- the detergent used according to the present invention also has a water softening function, so that together with the wash and with the capture of the colour molecules dispersed in the wash waters, a preventative action is also obtained with respect to scale forming, which makes superfluous adding an anti-scale additive to the washing machine.
- this detergent unlike most of the ones normally on the market, is of natural origin and can be disposed of more easily than ordinary detergents currently on the market. As a result it also avoids the possible arising of residues of deterging agents which may with time lead to stoppages and clogging in the drain pipes.
- the support according to the present invention proves better than those according to the state of the art, also from an environmental point of view.
- the support according to the present invention does not require to choose the items of clothing to be washed, allowing them to be introduced into the basket in a purely random way; it does not require to acquire particular abilities for dosing the additives, allowing to dose only the number of supports to be introduced into the basket; it acts effectively washing and avoiding to stain the fabrics of other items of clothing; it has a low environmental impact and is not harmful for washing machines; finally, it has a relatively modest manufacturing cost.
- the support allows to advantageously bring together the washing function, the capturing of the colours dispersed in the washing solution, possibly the softening function and optionally others, all in a single support which acts effectively on dirt, preserving the colours.
