Definitions

  • 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).
  • 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.
  • 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.
  • the present invention drastically reduces dead times since required solutions can be loaded in significantly lower time.
  • 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.
  • 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 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.
  • the composition is enriched with a specific foaming agent containing a suitable surfactant.
  • 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.
  • 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.
  • FIG. 1 depicts a schematic representation of a foaming generator module.
  • FIGS. 2-3 depict the foam application and ease of visual inspection during the dyeing process of a garment.
  • FIGS. 4-10 depict the appearance of the garment following treatment.
  • FIGS. 11-12 depict one embodiment of the foaming generator module.
  • 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.
  • 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.
  • Another aspect of the present invention relates to a module and related processes for generating these foam treatments for textiles or garments, as generally depicted in FIG. 1.
  • the present invention comprises at least one foaming agent that is used as a carrier of other chemicals used during the treatment of garments. As described in greater detail in Table 2, depending on the desired treatment, certain foaming agents may be more desirable than others. Persons of ordinary skill in the art would understand that a variety of foaming agents would be suitable and fall within the scope of the present invention.
  • the foaming agent is present in an amount of at least 1 g/L per kilogram of garment. For instance, according to at least one embodiment, the foaming agent is present in an amount ranging from about 6 to 100 g/L per kilogram of garment. Depending on the treatment or application, more than one foaming agent may be used.
  • the composition of the present invention further comprises at least one booster, which can be used to enhance the chemicals present in the composition and/or provide other benefits to the overall treatment process, for instance by shortening the treatment time.
  • Another aspect of the present invention relates to a foam composition that can be safely used to treat garments, where industrial laundry personnel can visually inspect the garment during the dyeing process without posing the safety issues present in known spraying applications.
  • the foam composition allows for the door of the washing machine to be opened at any time during the process for inspections and to check on the garments. (See FIG. 2, 3). Similar inspections are not feasible on systems based on aerosols, where personnel could be exposed to toxic chemicals through inhalation of small droplets of water contaminated with the chemical agents.
  • Another advantage of the present invention is the versatility it affords in terms of possible treatments on garments.
  • the examples described in greater detail below are understood to be exemplary and are provided to emphasize the variety of images and treatments achievable using the present method.
