Nippon Nozzle Spinnerettes

Spinnerettes (aka Spinnerets)

This page features information and images for Spinnerettes by Nippon Nozzle. Below are links to the Nippon Nozzle website, where there are detailed specifications for each product.

Nippon Nozzle was the first company to produce commercial Spinnerets (aka Spinnerettes) and today is one of the world-leaders in Spinneret manufacturing. They stand apart from the competition by their patented technology which allows them to create Spinnerets with holes considerably smaller than 100 microns.

Dry Spinning Spinnerettes

In dry spinning, the fiber-forming substance is melted for extrusion through the Spinnerette. Solidification is then achieved by evaporating the solvent in a stream of air or inert gas. Acetate, acrylic and spandex can be produced by this method.

Wet Spinning Spinnerettes

Wet spinning is used for polymers that need to be dissolved in a solvent first. The Spinnerette is immersed in tanks containing the solvent into which the filaments are extruded. Acrylic, vinyl, and rayon are produced by this method. Furthermore, Carbon Fiber can also be produced by this process. Carbon Fiber is a fibrous carbon material and can be classified into PAN-based, pitch-based and rayon-based. We also feature Carbon Fiber and PAN Polymerization plants, pilot plants, and equipment.

Melt Spinning Spinnerettes

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