Definitions

  • the present invention relates to a process and a composition for the laundering of textile fabrics.
  • the inventors have conjectured that the clay exerts its effect by remaining on the clothes after they have dried and acts as a sacrificial layer, to which dirt adheres and so is more easily removed during subsequent washing the next time. This avoids a build-up of particulate soil on the fabric.
