Title: Fiber spinning process and product thereof
Inventor: WENTHOLD RANDAL M
IPC: B29C48/21
Filed: 1992-03-30
Abstract: A significant increase in the rate of production of high quality symmetrical microporous hollow fibers can be obtained by a selection of raw materials, equipment and processing conditions. In particular, selection of polymer concentrates, precipitating solutions and fiber die dimensions are important to attaining production speeds greater than 30 meters per minute. In the processes, a polymer dope solution (12) is filtered through a filter press (16) and delivered to a dry-jet wet spinning spinneret apparatus (20) along with a precipitating solution (22). The solutions (12, 22) are spun from the spinneret apparatus (20) to form a hollow fiber which is quenched and wound on a take-up wheel (40). The product of the processes of the invention is a high quality fiber that can be used in a variety of medical end uses including renal dialysis, blood filtering, etc.
