Definitions

  • the invention relates to colour fading of material, such as coloured denim cloth, e.g. fading blue jeans.
  • material such as coloured denim cloth, e.g. fading blue jeans.
  • a bleaching agent for this purpose, and various bleaching compositions have been proposed for use in fading the jeans either in a water wash or in the absence of a liquid medium.
  • BE-A-905631 and its equivalent EP-A-0238779 to impregnate the bleaching agent into granules of coarse permeable material such as pumice stones.
  • Such material is natural and is of variable properties as a result of which the colour fading cannot be controlled.
  • a method of colour fading a material such as coloured denim, e.g. blue jeans, comprising contacting the material with a bleaching agent therefor, the bleaching agent being present in the pores of a porous carrier, characterised in that the bleaching agent is present in a preformed refractory carrier having a density of less than about 1 and a porosity of about 40% to 65%.
  • the material and the carrier are tumbled together in the absence of a liquid medium. In another preferred method, the material and the carrier are contacted together in a water medium.
  • the invention provides a method of making a preformed carrier for a bleaching agent for use in colour fading a material such as coloured denim characterised by mixing together a refractory material and a temporary filler to form a low density mix, adding a temporary binder, making a shape of the resultant bonded mix, burning off the binder and the temporary filler to form a porous carrier having a density of below about 1 and a porosity of about 40% to about 65%, and then introducing the bleaching agent into the carrier.
  • the mix of refractory material and the temporary filler are mixed with the temporary binder to form a mix which is extruded and/or briquetted.
  • the temporary filler is carbonaceous, e.g. napthalene, coal, coke, walnut stone, olive stone or the like.
  • the refractory material is a clay such as ball clay, or a grog, or the like. A fibrous material such as wollastonite may be present.
  • the temporary binder is water.
  • a mix of ball clay 30 wollastonite 30 napthalene 40 was blended with water to form a moist mix which was extruded and then briquetted.
  • the formed briquettes were fired at 1200°C to form briquettes having a density of about 1 and a porosity as measured by water absorption of 40% to 65%.
  • the briquettes were soaked in bleaching agent, lightly drained and then used to colour fade blue jeans by being tumbled dry until the jeans had a marbled finish. It was observed that the jeans were uniformly coloured i.e. there was no colour streaking. The briquettes could be reloaded with the bleaching agent after all the bleaching agent therein was used up.
  • the briquettes were subjected to a surface abrasive test and it was noted that there was less weight loss in the case of the briquette of Example 1.
