11351065 · 2022-06-07 ·

Two-sided warp-knitted fabrics having perforations possessing elastic qualities are usable in the medical industry for making warming products such as belts, bands, and compression bandages. A fabric includes, in its warp, wales having a closed-chain weave made of synthetic threads with elastomeric threads disposed inside of the wales, and, in its weft, thread systems made of a wool yarn or a yarn including wool, and, for a bandage, thread systems made of a natural yarn and/or an artificial yarn and/or a synthetic yarn. One system forms the front side and the other forms the back side of the fabric. The fabric has sections with weft threads missing in the courses of the fabric, and in the place of the weft threads are perforations, the minimal width of each perforation being equal to the distance between wales. A breathable fabric is produced suitable for making the aforementioned medical products.
