Method for deregistering crimped multifilament tow and product thereof |
摘要 |
<p>A method and apparatus for deregistering drawn crimped nylon multifilament tow includes the steps of stretching the tow under constant controlled tension at a temperature below the glass transition temperature of the nylon. The apparatus includes means for sensing the tension of the tow between the feed and draw sections of a stretching device and producing a signal representative of the tension sensed and a controller for changing the speed of the raw section actuated by said signal. <IMAGE></p> |
