Title (EN) HYDROPHILIC POLYESTER FIBERS
(FR) FIBRES POLYESTER HYDROPHILES
Abstract:
(EN) The present disclosure provides a process for preparing hydrophilic polyester fibers, said process comprising the steps of treating polyester fibers with a mixture comprising pre-determined weight proportions of at least one alkali and at least one hydrophilic polymer for a pre-determined period of time to obtain treated polyester fibers and curing the treated polyester fibers in an heated environment to obtain hydrophilic polyester fibers. The hydrophilic polyester fibers thus prepared demonstrate a wicking height of at least 2 cm in 30 minutes.
(FR) La présente divulgation porte sur un procédé de préparation de fibres polyester hydrophiles, ledit procédé comprenant les étapes de traitement des fibres polyester avec un mélange comprenant des proportions en poids prédéfinies d'au moins un alcali et d'au moins un polymère hydrophile pendant une période de temps prédéfinie pour obtenir des fibres polyester traitées et de durcissement des fibres polyester traitées dans un environnement chauffé pour obtenir des fibres polyester hydrophiles. Les fibres polyester hydrophiles ainsi préparées démontrent une hauteur de méchage d'au moins 2 cm en 30 minutes.
