Electrically conductive yarn has a stretch core filament, with an electrically conductive and a bonding filament wound around it to restrict the core stretch

摘要

The electrically conductive yarn has a stretch core filament, with an electrically conductive filament wound around it together with a non-conductive bonding filament of natural or synthetic fibers. The bonding filament limits the stretch of the elastic core. The core, of a natural rubber or synthetic elastic material, has a stretch to break of at least 50% and preferably at least 100% and especially at least 200%. The conductive filament is a metal wire, or a synthetic fiber filament or multi-filament yarn with a metal cladding.
