Process for the manufacture of short fibrils and devices for carrying it out |
摘要 |
A process is provided for the manufacture of fibrils of short length by suddenly releasing the pressure acting on a two-phase liquid mixture of molten polymer and solvent and which is at a high pressure and a high temperature. The two-phase liquid mixture is ejected through a pressure release orifice so as to vaporize the solvent instantaneously and solidify the polymer, and the flow path of the two-phase liquid mixture is perturbed at the instant when it enters the pressure release orifice.
