MECHANISM FOR CONTINUOUSLY PRODUCING NONWOVEN FABRIC WEB COMPRISING THERMOPLASTIC SYNTHETIC RESIN FILAMENT

摘要

PROBLEM TO BE SOLVED: To provide a mechanism capable of variably and properly adjusting filament properties and yielded nonwoven fabric properties at high filament speed, much filament feed amount and high filament exquisiteness. SOLUTION: The mechanism for continuously producing nonwoven fabric web comprising thermoplastic synthetic resin filament has a spinning nozzle, a cooling chamber, a drawing unit and an accumulating device accumulating filament on nonwoven fabric. The spinning nozzle can be fed with two or more different polymer melts and the device for collecting different polymer melts is set under a condition that bi-component or multi-component filaments flow out from the spinning nozzle opening of the spinning nozzle. The cooling chamber is divided into at least two cooling chamber parts in which bi-component filament or multi-component filament is contacted with processing air having each different convectively heat-exhausting ability.
