Abstract
A skin care fabric for medical, pharmaceutical or cosmetic use includes at least 80% by weight of microfibers that are a mixture of polyamide and polyester and have a diameter of less than 50 microns. Each microfiber is split to produce fine fibers closely packed in a parallel structure having a capillary effect and an abrasive effect. The fabric has a surface weight of less than 180 g/m2 and is loaded with medical, pharmaceutical or cosmetic active agents. The skin care fabric includes a warp-knitted fabric having a first surface and a second surface opposite the first surface, which is mechanically roughened and cut to become fluffy and yet short-haired and compact and resulting in a further surface enlargement of the fabric structure and a water absorbency of at least four times the surface weight of the fabric.
