摘要： A method of producing lyocell filaments employs a steam heatable spinneret having a rectangular shape with an aspect ratio of more than 2 and comprising at least a top housing and a nozzle frame. The spinneret is heated and used for spinning cellulosic filaments from a cellulose solution in a solvent. A lyocell process employs the spinneret.
