<p>1415049 Irradiating threads and webs FORSCHUNGSINSTITUT FUR TEXTILTECHNOLOGIE 4 June 1973 [5 June 1972] 26456/73 Addition'to 1341114 Heading B5B Natural or synthetic polymeric threads and webs are homogeneously irradiated with high energy ionizing beams and the reactive species thus formed are partially destroyed by the local application of pressure without the application of heat, and thereafter contacted with a shrinkage medium which may be a polymerizable monomeric substance, hot air, hot water or saturated steam. The pressure is preferably applied by means of an unheated patterned roller. The example shows the treatment of a polyamide knitted fabric.</p> |
