  • This invention relates to an apparatus for producing filaments by holding together polymers varying as to their properties in side by side relationship.
  • conjugate spinning method contemplated to produce variation in the internal structure of fibers capable of creating crimps simply during the course of spinning and stretching steps or other accompanying steps has been recently developed as a method for conferring crimps to thermoplastic fibers and looks to be taking place of conventional mechanical methods such as false-twisted system or the like.
  • conjugate spinning method lies in the reduction of production cost and the production of novel crimped yarns capable of creating new application field.
