Apparatus for producing multifilaments

摘要

An apparatus for producing multifilaments having high fiber strength is disclosed. A spinneret melt spins a polyolefin at a first temperature into filaments. A cooling duct cools the filaments via convection at a second temperature. A chill roll, disposed downstream from the cooling duct, has a third temperature, and forcibly conductively cools the filaments. Finally, heated drawing rolls, disposed downstream from said chill roll, continuously draw the filaments at a high draw ratio.
