Abstract

Фильера, содержащая трехарочные отверстия, может быть использована для изготовления элементарных нитей с трехарочным поперечным сечением. В некоторых примерах трехарочные отверстия имеют Y-образную форму с тремя зубцами, где каждый зубец содержит дугу на конце зубца, который сужается от конца дуги к месту соединения соседней дуги, а трехарочные элементарные нити имеют, в общем, Y-образное поперечное сечение, содержащее кончики дугообразной формы или в виде луковиц. Кроме того, трехарочные элементарные нити могут быть пригодны во множестве применений, включающих (но их состав не ограничен данным перечнем) фильтры, фильтры, содержащие добавки в виде макрочастиц, и фильтры для курительных устройств.
