Texturizing is a process that has existed since the middle of the 20th century and is mainly applied to synthetic yarns.
The process consists of modifying the behavior of the filaments (inside the yarn) to change the appearance of the finished yarn, generally giving it a rather fibrous appearance, which is softer and more elastic.
One of the texturizing processes was invented by Billion in the 1940s, and several others were exclusively carried out by Billion for many years: SOFILA is the company with the longest expertise in texturizing.
This deformed thread can then be recovered as it is (FT: False Twist) or it can be put back into an oven to set the twist (FTF: Fixed False Twist). Only synthetic threads are used for these FT and FTF operations
Unlike other processes, this technology does not aim to deform the yarn, but to spread its filaments to give it a more sparkling, flexible and elastic appearance.
The supply yarn generally passes over a heating roller, the temperature of which varies according to the material and the desired effect. It is then subjected to a spray of air and water under pressure, up to 10 bars, in order to modify its structure. Depending on the desired result, the yarn can also be dried or fixed by passing through an oven.
One of the great advantages of this process is that it is not limited to synthetic materials. SOFILA can apply it to various fibers such as polyester and polyamide, but also natural and artificial materials such as viscose, tencel and even silk.
