Preparation Of Hollow Fibers

  1. Use annular hollow, C-shaped or eccentric hollow spinnerets to form fibers through melt spinning (polyester, etc.) or solution spinning;
  2. Use hollow-type (sometimes C-shaped) spinnerets to form fibers through dry-wet spinning or melt spinning. Some centers need to be fed with air or coagulation liquids of different compositions to make a series of products.
