The synthetic multi filament yarn the device null synthetic multi filament yarn

摘要

The present invention relates to an apparatus for upsetting the crimped multifilament yarn a synthetic. The yarn is compressed as the plug thread-like body with a textured device in this case. Then thread the plug-like body is Kai-gu the yarn is crimped and is cooled using a cooling device. Thread plug-like body to pass through the heating section in the transition region between the cooling system and textured devices. This heating interval defines the interval between the yarn plug-like body receiving portion of the cooling device and plug thread-like body-emitting portion of the textured devices primarily. Adjusting means are provided to adjust the spacing between the thread-like body plug and receptacle plug thread-like body emitting portion in accordance with the present invention.
