In core-sheath fibre yarn, with/without additional single component fibres, the core and sheath are produced by extrusion of spinning polymers and at least nearly all fibres have a complete sheath. In the yarn the proportion of core-sheath fibres A is expressed below as %, of which each core-sheath fibre is (M +/- 0.1 M) % of the total volume of the particular core-sheath fibre: A max. = 100, M min 0.5, and A min. 30 + (0.1 M power 8. The core fibres can be polyethylene-terephthalate or polyamide 46 and the sheath can be polyamide 66, a mixture of polyamide 66 and poly(m-xylylene-adipamide), polyethylene-terephthalate, or a mixt. of polyethylene-terephthalate and polyvinylidene-fluoride. |
