Our Processes for the Pre-treatment of Fabrics
The pre-treatment of fabrics is a critical step on the journey to high-performance textiles, from tensile strength to colour fastness, quality is in everything that we do.
All fabrics, whether from natural or synthetic materials will have impurities. These are classified as either primary impurities or secondary impurities. Primary impurities are naturally occurring within the fibres of the fabric, while secondary impurities are additions that are accidentally added during the processes used to create the fabrics.
The pre-treatment of fabrics is essential for removing both primary and secondary impurities while giving the fabrics in question a number of desirable qualities. All inherent colours are removed, in some cases, the fabrics increase their water absorbency, and the pre-treatment processes ensure that when the fabrics undergo dyeing and printing that the colours are transferred in a uniform manner.
Before dyeing, printing, or finishing can be carried out, it is essential that the fabrics undergo pre-treatment.
Our pre-treatment of fabrics processes include:
Brushing
Is a mechanical process where fine metal brushes rub the face of the fabric to remove lint and fibres, producing a fabric softer handle.
Singeing
During this process, the 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
Is a 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
The process during 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.
We are Pincroft. And the journey towards high-performance textile starts with the pre-treatment of fabrics.
