THERMOPLASTIC ELASTOMER NONWOVEN FABRIC ROLL, AND METHOD ANDDEVICE FOR PRODUCING THE SAME

摘要

A method of producing a thermoplastic elastomer nonwoven fabric roll, which comprises the steps of forming a nonwoven fabric (131) in sheet form by stacking melt-spun thermoplastic elastomer filaments on a belt conveyor (115 ), stripping the nonwoven fabric (131) by guiding it to a rotational roller (2) disposed above the transfer region of the belt conveyor (115), and winding i t around a paper tube (132), thus forming a nonwoven fabric roll (130). Since the tension acting on the nonwoven fabric (131) substantially directly acts as the stripping force, the nonwoven fabric (131) can be stripped by only applying a necessary minimum tension thereto. As a result, it is possible to produce a nonwoven fabric roll (130) which is subject to less vertical wrink le associated with a draw-out tension of not more than 0.25 g/cm/Metuke (a Japanese unit of weight used in some areas of the textile industry) and subject to less change of shape attending on delayed recovery.
