Title:
超高分子量ポリオレフィン糸条とその製造方法及び延伸装置
Document Type and Number:
Japanese Patent JP5001472
Kind Code:
B2
Abstract:
An ultrahigh molecular weight polyolefin yarn of the present invention has been drawn and has a melting point that is determined as a maximum peak temperature measured by a differential scanning calorimeter (DSC) at a temperature rise rate of 20° C./min, and the melting point is higher than a melting point of the yarn before drawing. In a production method of the present invention, a drawing bath (3) that includes a hollow yarn path (14) and a jacket portion (13) in which a heated liquid circulates is placed in a drawing zone, and the yarn is heated and drawn while passing through the yarn path (14) in a non-contact manner. A drawing device of the present invention includes a feeder (1) for feeding a yarn, a drawing bath (3) for heating and drawing the yarn, and a winder (5) for winding up the drawn yarn. The drawing bath (3) includes a hollow yarn path (14) and a jacket portion (13) in which a heated liquid circulates. Thus, the present invention provides a drawing method in which a high strength ultrahigh molecular weight polyolefin yarn can be drawn stably even at a high draw ratio, a drawing device, and a yarn obtained by the drawing method.
