Abstract

L'invention concerne un procédé permettant de traiter un collant dans un processeur cryogénique pour produire des collants cryogéniquement traités présentant des qualités de port améliorées. Un tel procédé, peut entre autres, être généralement résumé par les étapes suivantes consistant à : réduire la température du collant à une température comprise entre -80 °C environ et -240 °C environ, pendant une période de 1 heure à 6 heures environ ; maintenir la température du collant entre -80 °C environ et -240 °C environ pendant 6 à 48 heures ; et permettre aux collants de se réchauffer pour atteindre une température d'environ 25 °C pendant 3 à 48 heures. Le traitement cryogénique du collant permet d'obtenir des qualités de port de collants améliorées.
