<p>A fabric intended to serve as an insert in working trousers or trouser legs for power-saw operators. The fabric consists of two layers, viz. a carrier layer or passive layer, wherein the threads (1) interconnect the threads (2) of the active layer, i.e. the layer, wherein on account of the contraction of the passive layer threads (1) caused by suitable treatment of them, the threads (2) of the active layer are forced to take on a sinuous configuration whereby at their contact with the saw chain the sinuous sections will be caught by the chain, and the threads of the active layer (2) be pulled out and thus so heavily oppose the movement of the saw chain that the latter is immobilized.</p> |
