1. A compression bandage in the form of a single knit obtained by warp stitch technology, the single knit consisting of synthetic yarns and comprising two textile surfaces of respective textile structures that may be identical or different, the two textile surfaces being interconnected by spacer yarn of the synthetic yarns, each of the two textile surfaces including elastic yarn of the synthetic yarns, said single knit not including adhesive and not including latex, and said single knit having:
a longitudinal stretch measured in compliance with the standard EN 14704-1 lying in the range 30% to 160%, and
a threshold shear stress of greater than or equal to 2800 Pa, wherein the threshold shear stress is a minimum shear stress that causes lateral slipping between two exterior faces of the single knit when pressed against each other with a force of 5.3 kPa, the two exterior faces respectively provided by the two textile surfaces, wherein
the spacer yarn is a monofilament that presents weight lying in the range 20 dtex to 80 dtex,
the single knit presents weight lying in the range 160 g/m2 to 370 g/m2 and a thickness lying in the range 1 mm to 2 mm,
the elastic yarn in one of the two textile surfaces presents weight lying in the range 40 dtex to 80 dtex, and
the two textile surfaces include thermoplastic yarns of the synthetic yarns presenting weights lying in the range 40 dtex to 90 dtex.
