Abstract
A compression stocking having shape memory, heat-shrinkable thermoplastic material, wherein said stocking is configured to establish, in use, a compression contact with at least one of a leg and a foot of a user upon the application of an amount of heat to the shape memory, heat-shrinkable thermoplastic material, wherein the thermoplastic material is a polymer that has a glass transition temperature below −10° C., has crystallinity with a melting temperature (Tm) between 30-50° C. and a heat of fusion of at least 10 J/g, as determined using differential scanning calorimetry (DSC) (−40° C./10.0 (K/min)/100° C.) as set out by the ASTM D3418:2003.
Claims5
A compression stocking, consisting of:
- 1) a nonwoven, shape memory, heat-shrinkable thermoplastic material,
- 2) optionally at least one attachment element, and
- 3) optionally a temperature controlling device,
- wherein said stocking is configured to establish, in use, a compression contact with at least ne of a leg and a foot of a user upon an application of an amount of heat to the shape memory, heat-shrinkable thermoplastic material, wherein the thermoplastic material is a polymer that has a glass transition temperature below −10° C., has crystallinity with a melting temperature (Tm) between 30-50° C. and a heat of fusion of at least 10 Jig, as determined using differential scanning calorimetry (DSC) (−40° C./10.0 (K/min)/100° C.) as set out by the ASTM D3418:2003.
