Abstract
(EN) Stable, heat-set, helically crimped fibers are economically produced with in-line fabric deposition and heat setting and are uncompacted to retain their loft.
(FR) L'invention concerne des fibres stables thermiquement stabilisées à frisure hélicoïde. Ces fibres sont produites par dépôt de tissu en ligne et par stabilisation thermique. Le fait qu'elles ne sont pas compactées leur permet de conserver leur gonflant.
