PREPARATION
Singeing
Some raw fabrics may show small fibrils on their surface due to friction during the weaving process. They can be easily removed by means of this process. The final fabric gets a better optical and tactile aspect. This process is mainly used for fabrics containing cotton.
Our singeing-machine is equipped with 2 distinctive flames; it’s possible to singe the fabric in 2 different ways: the flame can either lick the fabric directly or indirectly. Only one side of the raw material may be treated on request. The power of the flame is controlled at the exact temperature thanks to a laser sensor.
Mercerisiation
This process consists in the impregnation of the fabric in caustic soda, maintaining some tension in the fabric. The intern structure is modified.
The primary wall of the cotton fibre gets a rounder shape. As a result, the surface is cleaner and therefore shows a better reflection and brightness. The fabric’s tension during this process improves the tearing resistance and removes the permanent folds of the material.
