Definitions

  • This design patent application relates to a procedure for decolorizing denim by means of water jets at a high pressure and temperature.
  • pumice stone is in fact highly polluting and consequently it needs to be eliminated according to specific safety procedures which are complicated and costly.
  • the basic principle of the procedure according to the invention involves decolorizing the denim by means of a powerful jet of water at high pressure and at a high temperature; it should be noted in this regard that the item to be treated should be carefully ironed and stretched in front of the jet of water under pressure so that the jet may strike the item directly and uniformly, in order to energetically and easily penetrate all the fibres.
  • the clothing item could, above all in the case of trousers, be fitted on appropriately sized manikins which stretch the fabric of the clothing item completely and uniformly.
  • the method according to the invention it is also possible with respect to the previous technique, to reduce the procedure treatment times drastically in that, as described previously, in order to obtain a higher degree of decolorization, it is not necessary to lengthen the treatment time as in the case of the previous procedures, but simply to increase the pressure and the temperature of the jet of water.
  • the pressure of the water jet which strikes a clothing item stretched on an inflatable manikin must be adjusted not only according to the decolorization requirements but also according to the inflation pressure of the manikin which would otherwise prevent the forced water from penetrating through the fibres of the clothing item being treated.
  • a standard chemical additive could be added to the water in order to attack the dye of the fabric being treated.
  • a further advantage of the working procedure according to the invention is the fact that during the treatment, contrary to previous procedures, the decolorizing procedure can be controlled visually and can be interrupted as necessary, or continued as the case may be, until the fabric being treated is decolorized as necessary.
  • the decolorizing action of the denim may be obtained with water at a pressure varying from one to 120 atms and at a temperature varying from 20°C to 100°C; obviously the selection of the combination of a specific temperature and pressure will depend on the degree of decolorization and the operating times required for the procedure in question.
