  • METHOD FOR PRODUCING LYOCELL STAPLE FIBERS
    Publication number: 20220275537
    Abstract: The invention relates to a method for the production of lyocell staple fibers, comprising the steps in the following order: a) extruding filaments from a solution of cellulose in an organic solvent; b) precipitating the cellulose for the formation of continuous cellulose filaments; c) washing the cellulose filaments; d) contacting the cellulose filaments with a crosslinking agent; e) reacting the cellulose filaments with the crosslinking agent in a reaction chamber; f) washing the treated cellulose filaments; g) cutting the washed cellulose filaments into staple fibers; h) forming a nonwoven fleece from the staple fibers and pressing the nonwoven fleece; and i) finishing the nonwoven fleece and pressing the nonwoven fleece.
