Definitions

  • the present invention relates to a fabric treatment composition and a method of treatment of fabric.
  • cleaning methods are directed towards effective cleaning of soils from the fabrics.
  • Some cleaning formulations include soil release agents that make it easier for oily soils to be cleaned from fabrics.
  • conventional cleaning formulations do not help much in reducing subsequent post-wash soiling of the fabric.
  • One such method is a multi-step method of treating a fabric with a compound of alkaline earth metal, titanium or zinc, with a water-soluble compound of aluminium, and with C8-C24 soap, in presence of an aqueous carrier.
  • the multi-step method disclosed therein is relatively less convenient and relatively less user-friendly.
  • it must be communicated to the end-user to apply the ingredients to the fabric In a stepwise manner. End-users may not have adequate level of education to follow the instructions correctly and there is a need for a single step method for imparting hydrophobicity and reducing subsequent cleaning.
  • EP-A1-0 244 500 discloses a water repellent composition being liquid at room temperature, which comprises a silicone oil and a substantially non-volatile paraffinic oil or low molecular weight hydrocarbon resin, wherein the separation index of the paraffinic oll or low molecular weight hydrocarbon resin to the silicone oil is at most 0.4.
  • One of the objects of the present invention is to provide a method and a composition for treating a fabric to render the fabrics relatively more hydrophobic.
  • Another object of the present invention is to provide a method and a composition for treating a fabric to impart relatively better stain-resistance to the fabric.
  • composition comprising clay, silicone oil and fatty acid when contacted with a fabric in presence of water under specific pH conditions, renders the fabric hydrophobic.
  • a fabric treatment composition comprising clay, silicone oil, and fatty acid, characterized in that
  • a method of treatment of fabric comprising a step of contacting the fabric with the fabric treatment composition of the first aspect in presence of water.
  • the fabric that can be treated includes synthetic as well as natural textiles. Fabrics may be made of cotton, polycotton, polyester, silk or nylon. It is envisaged that the method of the present invention can be used to treat garments and other clothing and apparel materials that form typical wash-load in household laundry.
  • the household materials that can be treated according to the process of the present invention include, but are not limited to, bedspreads, blankets, carpets, curtains and upholstery.
  • the process of the present invention is described primarily for treatment of a fabric, it is envisaged that the process of the present invention can be advantageously used to treat other materials such as jute, denim and canvass. It is envisaged that the process of the present invention can be used to treat articles such as shoes and jackets.
  • the fabric treatment composition comprises at least 30% by weight of clay.
  • the clay is preferably from 30% to 90%, more preferably from 50% to 90% by weight and most preferably from 60% to 85% by weight of the fabric treatment composition.
  • the clay is a 2:1 clay.
  • 1:1 clays that can be used include kaolinite, dickite, halloyside, nacrite, chrysolite, lizardite, and amesite.
  • Preferred 2:1 clays are montmorrilonite, bentonite, and smectite.
  • the silicone oil is preferably from 3% to 50%, more preferably from 3% to 30% by weight and most preferably from 5% to 10% by weight of the fabric treatment composition.
  • Preferred silicone oil is polydimethylsiloxane.
  • silicone oils examples include Q2-1607 (ex Dow Corning), 1107 (ex Dow Corning), SF8417 (ex Dow Corning), Q2-8166 (ex Dow Corning), 2-8630, Q2-8460 (ex Dow Corning), 3-0213 (ex Dow Corning), 2-8040 (ex Dow Corning) and ARA-222 (ex Dyetech, Inc), SM2125 (ex Momentive performance materials), SMW32 (ex Momentive performance materials), SM2059 (ex Momentive performance materials) and AN101 (ex Resil), AE104 (ex Resil) and AE112 (ex Resil).
  • the fatty acid is preferably from 5% to 50%, more preferably from 5% to 30% by weight and most preferably from 5% to 20% by weight of the fabric treatment composition.
  • the number of carbon atoms in the fatty acid is preferably from 8 to 50, more preferably from 10 to 48, most preferably from 12 to 22.
  • the fatty acid is a saturated fatty acid.
  • the saturated fatty acid is preferably selected from lauric acid, myristic acid, stearic acid, palmitic acid, or mixtures thereof.
  • unsaturated fatty acids include oleic acid, linoleic acid, linoleinic acid, ricinoleic acid, elaidic acid, petroselenic acid, erucic acid, palmitoleic acid, myrostoleic acid, and 12-hydroxyoleic acid.
  • Fatty acid may be directly added to the composition, Alternatively, it is envisaged that a corresponding fatty acid soap and an inorganic or organic acid are added to the composition for in situ generation of the fatty acid in the composition.
  • the mass ratio of clay to fatty acid is greater than 1.
  • pH of the fabric treatment composition refers to pH of a mixture obtained by adding 1 part of the fabric treatment composition to 99 parts of water. It is essential that pH of the composition is less than or equal to 6.
  • the fabric treatment composition preferably comprises an acid other than the fatty acid in order to ensure that pH of the fabric treatment composition is less than or equal to 6.
  • the acid other than fatty acid is preferably from 0.1 % to 20%, more preferably 0.5 to 10% and most preferably from 1% to 5% by weight of the fabric treatment composition.
  • the composition may comprise a surfactant.
  • the surfactant if present, is preferably not greater than 5%, more preferably not greater than 2% and most preferably not greater than 1% by weight of said composition.
  • the fabric treatment composition may comprise other optional ingredients including fluorescer, perfume, and preservative.
  • the method of treating fabric comprises a step of contacting the fabric with the fabric treatment composition in presence of water.
  • the step of contacting the fabric with the fabric treatment composition in presence of water is at a pH less than or equal to 6.
  • the pH may be maintained by adding an acid to the fabric treatment composition.
  • an acid may be added during the step of contacting so as to ensure that the pH during the step of contacting the fabric is less than or equal to 6.
  • Fabric treatment compositions were prepared by mixing clay, poydimethylsiloxane (Q2-1607 emulsion from Dow Corning) and fatty acid and adding citric acid solution to adjust pH to 5 unless specified otherwise.
  • the % by weight of polydimethylsiloxane in the composition is given on water-free basis unless specified otherwise.
  • the fabric treatment composition was added to water (1.4 g of the composition in 200 mL of water) to prepare an aqueous suspension.
  • a fabric swatch (size 10 cm X 10 cm) made of desized cotton, polycotton or polyester (all obtained from Bombay Dyeing, India) was dipped in the above suspension. The liquor to cloth ratio of about three was maintained. After 15 minutes of soaking, the fabric swatch was removed from the suspension and dried at 40°C for about 1 hour. The dried swatches were then ironed.
  • the fabric treatment composition comprising at least 30% clay provides hydrophobicity on cotton, polycotton and polyester swatches whilst the fabric treatment composition comprising less than 30% by weight provides hydrophobicity only on polyester swatches. It can be further seen that the hydrophobicity of treated fabrics improves as the mass ratio of clay to fatty acid in the composition exceeds 1.
  • the fabric treatment compositions comprised stearic acid, silicone and sodium bentonite as tabulated below. All the treatments were at pH of 5. The results of evaluation of hydrophobicity are tabulated below.

  • the ompositions comprising at least 5% fatty acid by weight provide hydrophobicity on all substrates including cotton.
