Technical Specification

Surface Roughness of Spinnerets
Spinneret for spinning is the key component for any type of synthetic fiber spinning. We design and manufacture any kind of spinneret, especially spinneret for POY FDY spinning line with different cross-section shape of capillary hole in any filament yarn count.
