IMPROVEMENTS IN AND RELATING TO HOLLOW FIBER IDENTIFICATION |
摘要 |
<p>Hollow fibers are differentiated by their void being partially filled with a differentiating characteristic that is a protuberance of characterizing polymer material. This material may be the same or different from that of the rest of the fiber. The protuberance is provided by appropriate adjustment of the spinning capillary, i.e., during extrusion to form the fiber.</p> |
