ABSTRACT:
Hollow fibers are prepared by spray drying a solution of a film-former in a volatile solvent. The viscosity of the solution must be 1.5 to 10 times the viscosity that usually results in spheres or microspheres. The preferred film-forming substance is a combination of sodium silicate and a "polysalt."
