Texturization is a textile process designed to confer specific characteristics to continuous threads. Being a thermo-mechanical process, it is particularly suitable for chemical fibers which, due to their thermoplastic properties, assume a permanent deformation of the single component burrs. It can modify the hand giving bulk, elasticity or structural modification to the threads, the amount of the modification is adjusted at will, according to the need.
The false twist is a continuous process performed on machines with multiple positions where the wires, individually fed, undergo a torsion, a thermofixing and a distortion. The thermal memory of the fastening in high torsion condition gives the single burrs a wavy structure (FT wires). A second fixing between adjustable speed feeders, is able to reduce to the desired degree, elasticity, volume and tendency to twist the threads (FTF threads). A device, once a spindle, today mostly friction is able to impart the twist. The texturing process in its three phases: torsion, fixation and distortion, was once performed in three successive steps.
