Abstract
This invention relates to protective, multi-layered, breathable fabric constructs. The constructs which are flexible employ a fabric layer and a breathable coating layer applied to the fabric. Under certain preferred embodiments, the fabric constructs also employ an energy dissipating fiber material disposed opposite the coating layer. Also, the present invention teaches a method of protecting a valuable or sensitive object from damage caused by corrosion, weather, bio mass, or other environmental related conditions using the fabric material. The fabric constructs may be post-formed using heat or other methods to create shaped-to-form covers.
Claims51
A fabric construct comprising:
- a porous fabric layer;
- an adhesive layer applied to said fabric layer;
- a layer of flocked fibers applied to said adhesive;
- and
- a substantially waterproof, moisture vapor permeable polymeric composition applied to the porous fabric on the side opposite said flocked fibers.
A method of manufacturing a substantially waterproof moisture vapor permeable cover material comprising the step of:
- a. providing a fabric layer;
- b. applying an adhesive to the fabric layer;
- c. applying flocked fibers to the adhesive layer;
- and
- d. applying a substantially waterproof, moisture vapor permeable polymeric top layer to the fabric layer on the side opposite the adhesive and flocked fibers.
A fabric construct comprising a stitch reinforced two-stage non-woven entangled fabric and a water vapor permeable polymeric composition applied on a major surface of the non-woven fabric.
