A compression bandage that is formed by the assembling of a self-adhesive nonwoven based on short conjugate fibers which have been crimped and of an elastic material, the effectiveness of which increases over time. The bandage can be used, alone or in a bilayer compression system, for the prevention or treatment of venous pathologies or lymphedema.

A compression bandage formed by the assembling of a nonwoven based on short conjugate fibers which have been crimped and of a nonelastic material. The compression bandage can be used in a bilayer compression system, in particular for the prevention or treatment of venous pathologies.

A multilayer fabric includes a first fabric and a second fabric superimposed onto each other. The first fabric is a non-woven fabric comprising a plurality of crimped filaments, the crimped filaments including a plurality of crimps. The first and second fabrics are constrained to each other at a plurality of constraining points or zones, wherein the surface of the second fabric has an area greater than the area of the first fabric. At least one portion of the second fabric disposed between adjacent constraining points or zones, has a plurality of bulgy zones, the bulgy zones protruding outward from the surface of the multilayer fabric.

A thermally adhesive fiber web implemented by including the steps of: (1) preparing respectively a first spinning solution in which a support component and a second spinning solution in which a thermally adhesive component; (2) performing electrospinning such that the first spinning solution is discharged to a portion of the end surface of a discharge port and the second spinning solution is discharged to the remaining portion, thereby accumulating side-by-side type thermally adhesive composite fibers having a diameter of less than 1 m; and (3) applying heat to the accumulated side-by-side type thermally adhesive composite fibers. The thermally adhesive fiber web enables easy interfacial bonding to a heterogeneous material with a different material and structural specification and prevents pores formed in an initial stage from being closed during thermal bonding.
