Definitions

  • fibrous material with metal coatings there are several known types of fibrous material with metal coatings, amongst which are continuously coated fabrics, needle-punched metallised fibres, metal- coated fibres, and tape-like elements produced from metal-coated film.
  • the film is typically of a linear, substantially non-cross-linked polymer, such as a polyolefin, PVC, polyester, polyamide, polyethersulphone or polyetheretherketone (PEEK).
  • a preferred polymer is a polyolefin, especially a propylene polymer (which may be a homopolymer or an ethylene-propylene copolymer with a minor proportion of ethylene).
  • the ' polyolefin is preferably polypropylene with a melt flow index of approx. 8-10 gms per 10 minutes according to ASTM D1238.
  • the roll of metallised film 20 (which corresponds to wound roll 12 from Figure 1) is unwound, past an inlet trio of rollers 21 ,22,23, over a heated roller 24 and then over a pinned fibrillation drum 25.
  • the fibrillar network leaving drum 25 passes to stretch-breaking station 26 and then to can coiler unit 27 in which tow is laid in a can 28.
  • a 25 K/tex tow was produced as in Example 1 then processed on a stretch- break machine to give a sliver of 20grms per linear metre.

Abstract

On produit des fibres recouvertes de métal en débobinant un rouleau de film polymère orienté de manière uniaxe, en métallisant le film, en l'enroulant puis en déroulant le rouleau de film métallisé obtenu dans une zone de fibrillation dans laquelle le film est déformé et coupé de manière à produire un réseau fibrillaire qu'on peut ensuite ouvrir par cardage ou autre. Le matériau résultant comporte des fibrilles de denier compris entre 1 et 50 présentant chacune des surfaces plates parallèles, dont au moins une peut être métallisée, et dont l'épaisseur et la largeur varient entre 5 et 100 microns, la largeur moyenne ne devant pas excéder quatre fois l'épaisseur.
