A tube for difficult yarns
One of the most common problems that occurs during the dyeing process is the collapse of the tube, due to an elevated reentry of the thread.
The RETRAFLEX patented design comes from the need to have a tube able to control the thread's reentry in a gradual way.
Collaborating with our most important clients we have been able to verify through test of laboratory and especially through the direct experience in job, the exceptional resistance qualities of this tube.
The particular geometry of the circular elements that forms the structural grate of the tube, allows an easy shrinkage of the thread package that maintains a constant density. As soon as the thread reenters, the tube becomes stiff and opposes more resistance. We attach a file in Word format with the account of one of the resistance tests that we made on the RETRAFLEX for texturisation.
