Hybrid fabric

An immobilisation device for immobilizing a body part in a certain position, the immobilization device comprising:

• a hybrid woven or knitted fabric, comprising at least one structural fiber having a first melting temperature range and at least one thermo-formable fiber having a second melting temperature range which is lower than the first melting temperature range to such an extent that the structural fiber does not melt in the second melting temperature range of the thermo-formable fiber, wherein the hybrid fabric comprises:
• (1) a first network comprising the structural fibers,
• (2) a second network consisting of the thermo-formable fibers, and
• (3) a plurality of openings between the fibers of the first and second network, wherein the structural and thermo-formable fibers of respectively the first and second network interpenetrate one another and are connected to each other over at least part of the first and second network at a plurality of subsequent loops,
• wherein the hybrid fabric has a density of between 0.5 and 0.8 g/cm3 after thermoforming at a temperature of between 60-65° C., and
• wherein the at least one thermo-formable fiber is a non-relaxed monofilament fiber of partially cross-linked poly-ε-caprolactone being moldable at temperatures up to 40-45° C.
