Definitions

  • Overspray from paints and other sprayed materials is often present during spraying operations. Despite continuing efforts to transfer 100% of the sprayed material to the workpiece, some amount of the material often ends up as an airborne contaminant that can become attached to other surfaces besides the intended workpiece. There continues to be a need to protect these surfaces from the overspray.
  • a sheet material such as a nonwoven due to its high surface area, can effectively trap airborne contaminates in its undulating surface.
  • An adhesive can be applied to one side of the sheet material enabling it to stick to other surfaces needing protection such as walls, floors, ceilings, and/or the interior of a paint spray booth. Thereafter, the sheet material can be applied as a sacrificial layer to these other surfaces effectively trapping and containing the airborne contaminates that land on the protective material’s surface during spraying operations.
  • An adhesive nonwoven material for surface protection can be obtained from 3M under the name 3MTM Dirt Trap Protection Films and Materials available from 3M Company, St. Paul MN.
  • brackets attached along the length of a wall such that the nonwoven material can be pulled down to the floor and then pushed back into contact with the wall adhering it to the wall greatly simplifying the installation.
  • the brackets are designed to support a flanged core plug of the nonwoven roll and two such core plugs facing opposite directions can fit into one bracket reducing the number of brackets needed.
  • the nonwoven roll is supported by brackets that are attached to a trolley that transverses a track or a rail attached to the wall near its top. Using the track and trolley, the roll can be repeatedly indexed along the wall to apply multiple strips of the nonwoven material to the wall’s surface BRIEF DESCRIPTION OF THE DRAWINGS

Greige cloth, taken directly from the loom, is not processed through any additional finishing operations.” (taken from the website for American Fiber and Finishing Co., Albermarle, N.C.

  • the thread count and fiber denier can be selected such that a proper balance between material reinforcement, tackiness and adhesiveness is met.
  • the scrim is at least partially free from adhesive, if the scrim material has too high a thread count and/or too high fiber denier, then too much of the underlying pressure sensitive adhesive layer is covered by the scrim and the protection sheet is not tacky or adhesive enough to stay in place where desired. Conversely, if the scrim material has too low a thread count and/or too low fiber denier, then lamination to the adhesive surface becomes difficult, the adhesive surface is not reinforced properly, and the adhesive surface can become too tacky for easy positioning and removal.
  • the Dirt Trap material had a low adhesion backsize that provides a surface with a reduced adhesive affinity for the pressure sensitive adhesive. Such reduced adhesion facilitates the separation of layers as the roll is unwinding.

Compounds suitable as a low adhesion backsize are disclosed in U.S. Pat. No. 4,728,571 issued to Clemens et al.
