Claims15
A laminar structure comprising an expandable microspheres-containing elastomeric skin and a stretchable fabric attached thereto.
A laminar structure comprising an elastomeric skin to which is attached a stretchable fabric by means of an adhesive layer;
- at least one of the skin and the adhesive layer containing expandable microspheres.
A laminar structure comprising an elastomeric skin to which is attached on one side a stretchable fabric and on the other side an elastomeric top coat, at least one of said skin and said top coat containing expandable microspheres.
A laminar structure comprising an elastomeric skin to which is attached on one side a stretchable fabric by means of an adhesive layer and on the other side an elastomeric top coat, at least one of said skin, adhesive layer and top coat containing expandable microspheres.
A process for the production of laminated fabric structures comprising:
- affixing an expandable microsphere-containing elastomeric skin to a stretchable fabric to form a laminate;
- and
- expanding said microspheres in said laminate.
A process for the production of laminated fabric structures comprising:
- affixing an expandable microsphere-containing elastomeric skin to a stretchable fabric to form a laminate;
- and
- heating said laminate to expand said microspheres.
A process for the production of foamed laminated fabric structures comprising:
- affixing an expandable microsphere-containing elastomeric skin to a stretchable fabric to form a laminate;
- heating said laminate to expand said microspheres;
- vacuum forming said microsphere-expanded laminate in a mold;
- introducing liquid foamable composition onto said microsphere-expanded laminate in said mold;
- causing said composition to foam in a controlled manner;
- and
- removing said foamed laminated fabric structure from said mold.
A process for the production of laminated fabric structures comprising:
- affixing an elastomeric skin to a stretchable fabric by means of an adhesive layer to form a laminate wherein at least one of said elastomeric skin and said adhesive layer contains expandable microspheres;
- and
- expanding said microspheres in said laminate.
A process for the production of foamed laminated fabric structures comprising:
- affixing an elastomeric skin to a stretchable fabric by means of an adhesive layer to form a laminate wherein at least one of said elastomeric skin and said adhesive layer contains expandable microspheres;
- heating said laminate to expand said microspheres;
- vacuum forming said microsphere-expanded laminate in a mold;
- introducing liquid foamable composition onto said microsphere-expanded laminate in said mold;
- causing said composition to foam in a controlled manner;
- and
- removing said foamed laminated fabric structure from said mold.
A process for the production of laminated fabric structures comprising:
- affixing an elastomeric top coat to one side of an elastomeric skin;
- affixing a stretchable fabric by means of an adhesive layer to the opposite side of said elastomeric skin to form a laminate wherein at least one of said elastomeric topcoat, said elastomeric skin and said adhesive layer contains expandable microspheres;
- and
- expanding said microspheres in said laminate.
