Definitions

  • This invention relates to a process for producing an anti-slip treatment on a porous substrate, namely a nonwoven, textile or carpet substrate, by applying a polymer formulation, having a Tg in the range of -60°C to -40°C, to a porous material by spray, foam or print application.
  • An anti-slip surface is one which allows the treated material to remain in place, without exhibiting tackiness or a peel strength.
  • a non-slip surface is imparted to a porous substrate through the application of a surface treatment.
  • US-A-5,786,077 describes the use of colloidal silicas to produce a non-slip surface on paper.
  • US-A-2 187 659 describes the use of an emulsion polymer as a non-slip coating for a non-woven material.
  • the polymer formulation is applied to a flexible web backing, dried, then the dried formulation is foamed in an added step by exposure to steam or irradiation.
