Title (EN) A TEXTURIZED MULTIFILAMENT YARN WITH VARYING DENIER, APPARATUS AND PROCESS OF PREPARATION THEREOF
(FR) FIL MULTIFILAMENT TEXTURÉ À DENIER VARIABLE, APPAREIL ET SON PROCÉDÉ DE PRÉPARATION
Abstract:
(EN) The present disclosure provides a texturized multifilament yarn comprising a plurality of texturized filaments wherein each filament varies in denier along its length. The present disclosure also provides an apparatus (100) and a process for preparing the yarn comprising varying denier along its length. The process comprises feeding filaments (101) into a processing unit (103) using a feed roller (102) followed by processing and drawing the filaments (101) simultaneously to obtain texturized filaments. A plurality of texturized filaments is obtained and combined to obtain the texturized multifilament yarn (107). The present disclosure uses a simple and direct process to achieve lengthwise variation in denier of the yarn for obtaining improved aesthetic characteristics of the yarn.
(FR) La présente invention concerne un fil multifilament texturé comprenant une pluralité de filaments texturés, chaque filament variant en denier sur sa longueur. La présente invention concerne également un appareil (100) et un procédé de préparation du fil comprenant un denier variable sur sa longueur. Le procédé comprend l'introduction de filaments (101) dans une unité de traitement (103) à l'aide d'un rouleau d'alimentation (102), suivie du traitement et de l'étirage simultanés des filaments (101) pour obtenir des filaments texturés. Une pluralité de filaments texturés est obtenue et combinée pour obtenir le fil multifilament texturé (107). La présente invention utilise un procédé simple et direct pour obtenir une variation en denier du fil, dans le sens de la longueur, pour obtenir des caractéristiques esthétiques améliorées du fil.
