The invention relates to a wound dressing which prevents or at least reduces sticking of the dressing to the surface of the wound due to contact with moisture from the wound and which without the use of over twisted threads has a controllable lifting action and an excellent secretion-absorbing action, whereby cutting of the dressing into strips does not lead to lateral fraying due to the cutting of the mesh as is the case with known knitted fabrics and in which the further use leads to complication. The present wound dressing comprises a knitted fabric formed with a basic stitch construction and with a plurality of inlay threads having a Z or S twist, the yarns of the inlay threads having the same thickness and twist, and being inserted as slightly or greatly displaced wefts.
A warp knitted fabric for use as a surgical bandage and dressing comprising four yarns arranged in a plurality of wales and causes including a first yarn comprising a basic stitch construction (L1) and second, third, and fourth yarns bound in as in-laid threads (L2, L3, L4), said fourth yarn consisting of a thick, roughened binding yarn of high volume bound in warpwise, said second and third yarns consisting of cross filling long looped, highly twisted yarns of sinuous configuration having a twist of one of the Z-twisting direction and S-twisting direction, one of said second and third yarns being bound in between two adjacent wales and the other of said second and third yarns being bound in between three adjacent wales.
