Abstract

La protesi viene ottenuta intrecciando un filo di fondo (1) ed almeno un filo di effetto (2). Il filo di fondo (1) presenta un elevato grado di termoretraibilità mentre il filo di effetto (2) è sostanzialmente termostabile. L'intreccio così ottenuto viene quindi riscaldato, ad esempio per immersione in acqua bollente, così da determinare un restringimento del filo di fondo (1), con conseguente riduzione della permeabilità ai liquidi. Il restringimento non interessa in misura apprezzabile il filo di effetto (2). E' quindi possibile ottenere buoni effetti di vellutatura senza ricorrere al tasso di sovralimentazione del filo di effetto (2) molto elevati.(Figura 4).
