  • A Process for Manufacturing Lyocell Filament Yarn and an Apparatus Thereof
    Publication number: 20220290329
    Abstract: The present invention relates to a process for manufacturing lyocell filament yarn with improved mechanical properties and an apparatus thereof. The process involves washing of filament yarn with sequential decrease in NMMO concentrations and filament yarn drying under relaxed conditions. Additionally, the present invention also provides a compact washing and drying apparatus that uses controlled air gap spinning thereby resulting in production of LFY under relaxed conditions and also having a higher mechanical properties & productivity.
