Industrial textile treatments on garments are generally performed using large washing machines loaded with garments and water. Chemical products are added to perform a variety of treatments, including but not limited to desizing (removal of sizing starch), stonewashing (enzymatic), scouring, cleaning, and finishings. In most cases, the treatments require considerable amounts of water. Typically, the chemical products are dissolved or mixed into a medium, usually water, in order to adequately disperse the substances produced during the process (e.g., the dispersion of the indigo dye released in the water during a stonewashing process) and to promote the interactions between the chemicals and the substrate. Generally, the ratio of weight fabric to water ranges from 1:3 to 1:20. Therefore, a simple treatment, which would include multiple steps, including for instance desizing, stonewashing, cleaning and finishing, where each step may require up to 20 liters of water for each kg of garment treated per cycle, consumes a significant amount of water. Further still, this significant consumption of water is often accompanied by considerable consumption of energy and carbon dioxide emissions if the chemicals require higher temperatures to work properly.
Public awareness of environmental problems is constantly increasing worldwide, and the textile industry is often critiqued for generating major environmental concerns due to the following aspects:
Use of massive resources of water.
Consumption of considerable amount of energy.
Considerable CO2 emissions, thus contributing to climate changes.
Use of chemicals dangerous for health or for the environment.
In order to address this criticism, many chemical manufacturers, such as Kemin Textiles and Auxiliaries, have adopted a strategy of formulating chemicals with the least amount of toxicological and ecotoxicological aspects. Simultaneously, raw materials capable of performing at lower temperatures have been used to reduce energy costs (e.g., cellulases that exhibit their best performance at temperatures lower than 40° C.).
Concerns related to the excessive consumption of water have also been addressed by some manufacturers of equipment for industrial laundries. One solution has been to increase the liquor ratio (ratio of weight of fabric to water weight used in a specific washing step) by decreasing the amount of water introduced into the washing machine as much as possible. This can be obtained by dissolving or dispersing the required chemicals into a limited amount of water, which is subsequently sprayed into the washing machine. These kinds of systems are capable of performing treatments with a roughly 1:1 liquor ratio, for instance, limiting the total amount of water consumed. Further still, a considerable amount of water is still needed during the rinses in order to remove the chemicals and other impurities. Another drawback to this approach is that it poses health and safety risks, including but not limited to the possibility of breathing in the aerosol formed during the treatment.
Concerns are particularly significant if the aerosol contains chemicals that may be detrimental to human health. For example, even micro-droplets of water containing biochemical substances, such as enzymes, represent a potential source of sensitization. For these reasons, some manufacturers require expensive and complex modifications on traditional washing machines. Other manufacturers have developed specially sealed equipment that prevents the leaking of aerosol recognizing the areas of washing machines that are most susceptible to aerosol leaks are the inlets and openings used for manual dosage of products.
An additional drawback of spraying devices is the inability to use suspensions recognizing that nozzles may become blocked, or occlusion may occur, if small solid particles are dispersed in the solution. For instance, pigments and enzymes coated with titanium dioxide or other insoluble materials should be avoided. This poses a limitation in terms of the versatility and usability of these systems.
Moreover, during normal treatments the operators often stop the washing machines to perform visual inspections on garments. This kind of operation is not possible on machines that adopt spraying devices since opening the window would expose the operators to the danger of inhaling the aerosol.
Another relevant drawback of spraying devices coupled with washing machines is the loading time. For instance, to achieve a 1:1 liquor ratio, each kg of garment requires at least one kg of a solution to be sprayed under the form of aerosol through nozzles. Nozzles with great orifice diameter (for instance, approximately or about 1 mm) could be used to reduce spraying time but that would translate into drops that may cause unacceptable spots in garments. For that reason, spraying devices coupled with washing machines are equipped with nozzles having very small orifice diameter (for instance, less than 0.2 mm). An industrial washing machine loaded with 50 Kg of garments typically requires from 30 to 50 minutes of continuous nebulization before the desired liquor ratio is reached and the treatment can start. That poses severe limitations in terms of productivity.
The present invention offers a new approach to the treatment of textiles or garments, including novel compositions and related methods using foam as a carrier of chemical products. For instance, these chemical products may include softeners, finishing agents, enzymes for stone wash or for discolorations, bleaching agents, and others readily known by those in the industrial treatment of garments. The inventions as described herein drastically reduce the amount of water needed. This reduction of water translates into a considerable saving on the cost of energy and a reduction of carbon dioxide emissions. The present invention offers numerous advantages over other systems based on sprays because it eliminates the concerns related to the nebulization of sensitizing agents, such as cellulase and other enzymes. Additionally, compared to other spraying-based systems, the present invention drastically reduces dead times since required solutions can be loaded in significantly lower time. Moreover, unlike conventional spraying-based systems, the present invention is also suitable for applications of suspensions of solid particles such as pigments or enzymes coated with non-soluble materials.
The presently disclosed invention improves on existing laundering processes and compositions, which translates into significant reductions in input and energy costs, as well as reducing the amount of carbon dioxide emissions.
The present invention relates to improved compositions and related methods for laundering or treating garments in the textile industry. The present invention relates to the treatment of textiles or garments, including novel compositions and related methods using foam as a carrier of chemical products. For instance, these chemical products may include softeners, finishing agents, enzymes for stone wash or for discolorations, bleaching agents, and others readily known by those in the industrial treatment of garments. Unlike conventional solutions based on aerosol or micro-bubbles, the presented method relies on foam as a carrier of the chemical products.
One advantage of the present invention is that it greatly reduces the amount of water required, where the required amounts of chemical products are dissolved in a limited volume of water in order to perform various treatments. According to at least one embodiment, the composition is enriched with a specific foaming agent containing a suitable surfactant.
Once the foam has been injected into the washing machine, it is easily spread over the garments by the simple mechanical action of the washing machine. Depending on the rotational speed of the drum and its geometry, it may take less than two minutes to obtain perfect homogenization of the foam on garments.
For instance, a given volume of solution requires less time to be injected as foam into a washing machine than would be necessary for the same volume to be injected utilizing conventional spraying systems.
If a non-homogeneous design on garments (for example, during a bleaching process) is required, this can easily be obtained by adjusting the flow rate of the foam into the washing machine. This element represents another advantage over existing processes that rely on aerosol, which does not have sufficient versatility or flexibility to perform non-homogeneous applications.
Another advantage over aerosol-based systems is the possibility of using solutions incorporating dispersions of non-soluble particles, such as pigments and coated enzymes.
Perhaps the greatest advantage offered by the presented method over systems based on aerosols or sprays is the absence of issues related to inhalation of dangerous substances. For instance, the door of the washing machine can be opened at any time during the process for inspections and to perform checks on garments. Similar inspections are not feasible on systems based on aerosols, since they would expose the operator to inhalation of small droplets of water contaminated with chemical agents.
Another aspect of the present disclosure includes a method of creating foam for textile treatment, including pumping a treatment solution into a first inlet of a T-junction, compressing air and urging the compressed air to a second inlet of the T-junction, combining the treatment solution and the compressed air in the T-junction, and creating a treatment foam by urging the combination of treatment solution and compressed air through an amount of stainless steel sponge contained within a cartridge.

The present invention provides enhanced productivity compared to existing systems based on sprays. The example described below is understood to be exemplary and is provided to emphasize the advantage in terms of productivity compared to existing methods aimed to save water consumption.
The prototype schematized in
(1)Nimbus system is suitable only for small loads of fabric.
Another aspect of the present invention relates to the process for making the foaming composition. According to at least one embodiment, as depicted in
The first inlet includes a liquid mixture that is mechanically pumped to the T-junction. The liquid mixture includes water, a foaming agent, and the chemical treatment intended to treat the textiles. The liquid mixture or solution is held is a vessel such as a flask. The liquid mixture is then pumped from the vessel to the T-junction via a pump. This pump is preferably a peristaltic pump which is more sterile because it does not need extra valves or seals to function. One example of a suitable peristaltic pump is the Digital Peristaltic Pump PV from Bram Dosing Systems. The pump may also be any other pump with or without an adjustable flow rate, a suitable venturi device, or a pulse pump if higher flow rates are needed for larger washing machines.
The second inlet is a line for compressed air. Ambient air is pulled in and compressed in an air compressor. The compressed air is preferably compressed to about 6 bar, and urged through a flow rate regulator. An example of a preferred flow rate regulator is the RFO-346 by Camozzi which has a nominal pressure of 6 bar.
The liquid mixture or solution of the first inlet and the compressed air of the second inlet are introduced in the T-junction. The T-junction may also be replaced by a venturi suction device. In certain applications, both the T-junction and the pump may be replaced by a venturi suction device. The solution and the air are mixed and are then urged out of the outlet of the T-junction by the pressure of the solution from the pump and the pressure of the air from the compressor. The outlet includes a PVC pipe or cartridge filled with stainless steel sponges. The cartridge is preferably about 32 cm long and about 4.5 cm internal diameter. The liquid solution and air mixture are urged through the sterile stainless steel sponges which creates a tremendous amount of turbulence within the mixture as it is urged through the sponges, which then creates the foam that is delivered to the textiles within the wash drum.
The present invention solves the problem of excessive use of water caused by nebulization systems. In nebulization systems, small droplets of water are sprayed inside the washing machines. The water droplets, which act as a carrier of chemicals, can easily escape from the washing machines if they are not adequately sealed, or if operators open the door of the washing machine to perform checks on the textiles. To avoid leaks of fog containing the treatment chemicals, the washing machines require technical modifications to ensure proper sealing. The inventors have addressed these problems through the present invention, which provides for a foam application that can remain inside the washing machine.
Further, the potential inhalation of chemicals by employees remains a serious problem during garment treatment processes, particularly where employees frequently may be exposed to toxic fumes when checking on the garments during the conventional industrial laundering process. This concern can be addressed by the present invention, e.g. through structural modifications on washing machines, as described herein. For instance, the any traditional washing machine could be easily adapted in order to work with the new system and coupled with an external module that has the purpose to produce foam with different densities, in different amounts, and with different amounts of chemicals dispersed, by simply adjusting the pressures of the first or second inlets, and by varying the density and amount of stainless steel sponge. No special or expensive dedicated washing machines (sealed washing machines) are required. The cost of the hardware is consistently lower than other system that have the aim to save water and energy. The module of the present invention may also be designed to fit internally in and integrally with a washing machine.
