A process for treating pantyhose in a cryogenic processor to produce cryogenically treated pantyhose that have enhanced wearing qualities is described. In this regard, one such process, among others, can be broadly summarized by the following steps:reducing the temperature of the pantyhose to between about -80~ C and about -240~ C over about a 1 to 6 hour time period; holding the temperature of the pantyhose between about -80 ~ C and about -240 ~ C for a 6 to 48 hour time period; and allowing the pantyhose to increase in temperature to about 25 ~ C over a 3 to 48 hour time period. The cryogenic treatment of pantyhose results in enhanced wearing qualities.

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.
