MELT BLOWING HIGHLY ORIENTED FIBERS
A thermoplastic condensation polymer is melt blown at an initial velocity of 150 to 300 m/s at a temperature which is less than 50 DEG C above its crystalline melting point and at which the molten polymer has an apparent melt viscosity of less than 50 poise. The melt blown fibers are collected to fo...

| Abstract | A thermoplastic condensation polymer is melt blown at an initial velocity of 150 to 300 m/s at a temperature which is less than 50 DEG C above its crystalline melting point and at which the molten polymer has an apparent melt viscosity of less than 50 poise. The melt blown fibers are collected to form a non-woven web, e.g. while being contacted with hot air heating the fibers to 70-265 DEG C. A suitable apparatus is shown. |
