Definitions

  • the invention relates to a process for cleaning fabrics. It particularly relates to a multi-step process for cleaning fabrics.
  • Conventional process of cleaning fabrics is typically a single step process of contacting a fabric with a detergent formulation in presence of water.
  • this process involves soaking fabrics in a soak solution of commercially available detergent formulations in water, followed by washing, and then followed by rinsing to get rid of excess water, dirt and leftover surfactant.
  • the steps of washing and rinsing are usually aided by means of agitation, provided either manually as in hand-wash or mechanically as in machine wash.
  • cleaning performance deteriorates with increase in water hardness, or with decrease in wash temperature.
  • Conventional processes also require longer time and consumption of high quantity of water.
  • GB338121 (1930 ) describes a process of washing by adding together or one after another two components to the wash where the first component comprises saponifiable fatty acids such as oleic acid, palmitic acid, or stearic acid and the second component comprises alkaline saponifying agents such as sodium carbonate, sodium bicarbonate or sodium hydroxide.
  • saponifiable fatty acids such as oleic acid, palmitic acid, or stearic acid
  • alkaline saponifying agents such as sodium carbonate, sodium bicarbonate or sodium hydroxide.
  • the above process involves fatty acids which are not readily soluble in water and solvents are used to solubilize fatty acids to facilitate their uniform application to fabrics.
  • Other approach is use of an emulsifying agent for forming an aqueous emulsion to facilitate uniform application of fatty acids to fabrics.
  • FR1460904 (1966 ) describes a process of washing fabrics in which aqueous emulsion of saponifiable fatty acids is combined with the alkaline wash solution.
  • Fatty acids are preferably selected from oleic acid or low-melting fatty acid mixture and emulsifying agent is a low HLB nonionic surfactant.
  • GB333177 (1930 ) describes a process of washing consisting of successively treating the material to be washed with a dilute emulsion of saponifiable fatty acids and with a dilute alkali to generate soap in-situ.
  • GB501422 (1939 ) describes a process for washing articles with a fatty acid component and an alkali component where the aqueous fatty acid emulsion comprises methyl cyclohexanol.
  • GB2315762 (Procter and Gamble, 1998) describes a detergent composition comprising a detergent surfactant, a dicarboxylic acid source and an alkaline source.
  • Dicarboxylic acid source is selected from fumaric acid, malic acid, maleic acid, tartaric acid, malonic acid, or a salt or ester thereof.
  • EP11767501 (Procter and Gamble, 2002) describes a process of washing a fabric by successively treating the fabric, in any order, with a first component and a second component which are capable of generating heat upon contact.
  • the components are selected such that contact of the components is a part of an exothermic process of either a physical or a chemical nature and results in generation of heat.
  • a list of exothermic processes is given and includes dissolution of organic/inorganic salts, oxidation/reduction, hydration of substantially anhydrous compounds and acid/base reactions.

  • Preferred organic acids include choloro acetic acid, dichloro acetic acid, acetic acid, oxalic acid, formic acid, lactic acid or mixtures thereof.
  • strong acids which are water soluble helps in eliminating problems related to use of insoluble fatty acids as there is no need to use solvents or emulsifying agents.
  • strong acids are difficult to handle, store and keep out of reach of minors. For consumers who prefer hand-wash, it is particularly problematic to handle strong acids and keep them out of reach of children.
  • packaging of strong acids is another issue which may lead to leaking or may require expensive packaging materials.
  • strong acids such as mineral acids may not be compatible with the material of construction of washing machines. Strong acids may also cause damage to expensive and delicate fabrics or textile accessories like buttons and elastic.
  • one of the objectives of the present invention is to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
  • Another object of the present invention is to provide a process for cleaning fabrics which causes relatively less damage to fabrics.

  • the soiled fabric swatches (10 cm x 10 cm) were first treated with the first component comprising organic acid, followed by contacting with the second component comprising alkaline material. Experiments were also carried out where order of contacting was reversed, i.e. the second component was contacted with fabric and the wetted fabric was then contacted with the first component. All experiments were carried out with 5 fabric swatches and the results reported are for 5 replicates, unless specified otherwise.
  • the first component When the acid used was water soluble, the first component was in form of aqueous solution. Water insoluble acids were dissolved in chloroform. The first component was contacted with the fabric swatch by pipetting the solution on to fabric (2 mL per swatch). The wetted fabrics were then soaked in the second component (in form of aqueous solution of alkali). Sodium carbonate, sodium tripolyphosphate and mixtures thereof were used as alkali (0.1-3 g/L sodium carbonate and 0.1 - 3 g/L sodium tripolyphosphate).

Soaking time of 30 minutes was used in the experiments, unless specified otherwise. Wash liquor to cloth ratio (by weight) was maintained at 50 in the tergetometer. In launderometer, the wash liquor to cloth ratio (by weight) was varied from 10 to 50. The wash time duration was 15 minutes.
  • the agitation in the tergetometer was provided by a vertical spindle rotating at an angular speed of 75 RPM and in the launderometer by a tumbling mechanism at a speed of 45 RPM.
  • Reflectance of fabrics was measured as an indicator of cleaning efficacy. Reflectance measurements, at 460 nm wavelength, before and after wash were carried out with the help of Gretag Macbeth reflectometer (Color Eye 7000A). The UV component of the incident light was blocked by appropriate filter devices, built in the system, in order to avoid any possible artifacts on account of fluorescence emitted by fluorescer molecules if present on fabric. Measurements of reflectance are based on 5 swatches, and expressed as: mean ⁇ standard deviation.
  • Breaking strength of fibers was used as a measure of damage to fabrics.
  • Texture analyzer Instron Series IX (TA Instruments, TA-HDi) was used for measurement of strength of fibers. Individual fibers were drawn out from the washed fabrics. A single fiber was attached to the fixture meant for tensile strength measurement and axial tension was applied. A 5 kg load cell was used for the experiment. Care was taken so that the fiber was stretched between the load cell and the bottom fixture prior to the application of axial tension. The load cell was pulled upward at a rate of 1 mm/s till the fiber withstood the applied tension. When the applied tension exceeded that of the tensile strength of the fiber, the fiber snapped and the corresponding tension at the break was noted.
