Definitions

  • the present invention is directed to cloth-like, liquid-impervious, breathable composite barrier fabrics. More particularly, the present invention is directed to cloth-like, liquid-impervious, breathable film-nonwoven composite fabrics having biological liquid barrier capabilities for use as, for example, sterilization wrap, surgical draping, surgical gowns, cover garments, such as over-suits, and the like.
  • Each nonwoven layer 12 and/or 18 may itself comprise a single layer of meltspun fabric, for example a spunbond or meltblown layer, or each nonwoven layer 12 and/or 18 may comprise a plurality of separate nonwoven layers comprising any of identical layers, similar layers, or different layers.
  • each of the nonwoven layers 12 , 18 may comprise a spunbond layer and a meltblown layer, or a first spunbond layer, a meltblown layer, and a second spunbond layer. Additional layers and combinations are possible as well, depending on the intended use of the product.
  • any of the nonwoven layers may be treated with an antistatic agent, a surfactant to impart hydrophilicity, or any other useful surface modifying agents so long as such an agent does not interfere with the intent of the invention.
  • Such multilayer films 20 may be formed by a wide variety of processes well known to those of ordinary skill in the film forming industry. Two particularly advantageous processes are cast film coextrusion processes and blown film coextrusion processes. In such processes, the two or three layers are formed simultaneously and exit the extruder in a multilayer form. Due to the extremely thin nature of the multilayer films according to the present invention such processes will most likely prove to be the most advantageous though it also may be possible to form multilayer films using separate extrusion processes.
