Abstract
The present disclosure relates to a polyethylene fiber and a method for preparing thereof, and more particularly to a polyethylene fiber, a method for preparing thereof, and an apparatus for preparing thereof, which has excellent wearing and touch sensation with processing convenience into woven fabrics and knitted fabrics in use in applied products by reducing the stiffness of fiber having the same physical properties using an enforced necking method in a spinning process.
Claims9
A method of preparing a polyethylene fiber, comprising the steps of:
- melt-extruding a polyethylene resin composition to obtain a polyethylene undrawn yarn;
- and
- passing the polyethylene undrawn yam through a heated collar section with a process of enforced necking the polyethylene undrawn yarn in an enforced necking zone in the heated collar.
An apparatus for preparing a polyethylene fiber, comprising:
- a feeder for providing a polyethylene resin composition;
- an extruder for melt-extruding the polyethylene resin composition supplied from the feeder;
- and
- a heated collar section in which the melt-extruded polyethylene undrawn fiber passes and is maintained at a temperature of 200° C. to 300° C.,
- wherein the heated collar section contains an enforced necking zone maintained at a temperature higher by 50° C. to 100° C. than the surrounding heated collar section
