SPINNERETS FOR MELT SPINNING

SPINNERETS FOR MELT SPINNING

In melt spinning, the fiber-forming substance is melted for extrusion through the spinneret and then directly solidifed by cooling. Nylon, Olefn, and Polyester are produced in this manner.

Shaped fibers can be made by using spinnerets with non-round holes. Let us know your requirements and we can help you design the spinnerets.
