Pre-treatment

WHERE THE JOURNEY FOR A GREAT PERFORMING FABRIC STARTS

In pre-treatment the fabrics are carefully prepared for following processes including dyeing, printing or finishing.

At this stage impurities and natural accompanying substances are removed to continue with processing of the textile. By changing the fibre structure, new properties can be obtained.

Pre-treatment includes:

Brushing
It’s a mechanical process where fine metal brushes rub the face of the fabric to remove lint and fibres, producing a fabric softer handle.

Singeing
The process where a fabric is passed through a gas flame to burn off any projecting fibres, yarn ends and fuzz.

Desizing
Is the process of removing a matter called ‘size’ added to the grey fabric to facilitate weaving. Once this is removed fabric becomes hydrophilic and suitable for dyeing.

Scouring
Chemical process in which the fabric is treated to remove oil, fat, wax and other natural and added impurities, in order to help accelerate dye and chemical absorption of the fabric, improve handle and remove natural colour.

Bleaching
Process in which the grey fabric is decolourised by removing inherent and or acquired colouring components from the fibre to provide base whiteness to the textile material.

Mercerising
Is the chemical treatment of raw material where fibres are made to swell in order to increase the lustre and dyeability the textile.
