in all directions, elastic band, foretredesvis intended to anvendas like bandages, and still for its framstellning

摘要

A fully elastic dressing material, that is a fabric band which is elastic in all directions, is knitted on a Raschel machine and comprises warps knitted into chains, and connected by elastic wefts. The fabric may comprise only chains knitted from elastic yarns 1 and laid-in elastic wefts 2 but may also include additional chains of non elastic yarns 3. The elastic yarns may be elastomeric and wrapped with textile yarns and the non-elastic yarn may be cotton or viscose staple. The elastic yarns are knitted under tension and, when the fabric is released, these retract while the non- elastic yarns form loops. The needles of the machine are passed through the bands undergoing formation while omitting periodically at least one needle between two chain warps in the interlacings which form the chain warps and the bindings of the transversal weft yarns with the chain warps in order to provide a retraction space. The bands thereby produced have selvages which are uniform and flat. IMAGE
