摘要 |
A spinneret having tri-arc holes may be used to produce tri-arc filaments. In some instances, tri-arc holes have a Y-shape with three prongs and each prong having an arc at the end of the prong that tapers from the end of the arc to a connection point of an adjacent arc, and tri-arc filaments have a generally-Y shape cross-section with bulbous or arcing tips. Further, tri-arc filaments may be useful in a plurality of applications including, but not limited to, filters, filters comprising particulate additives, and smoking device filters. |
