Fabric FinishesThe Final Step
What is Finishing?
Rarely is a fabric suitable for making into clothing etc. as soon as it has been woven or knitted. Usually it is subjected to a series of finishing processes, which give it the properties necessary for its purpose.
Finishing processes usually have 3 basic purposes:- To eliminate deficiencies in the fabric- To produce stable dimensions- To include special properties
General P
urpose
• Singeing
• Mercerising
• Carbonising
• Bleaching
• Stentering
Special Purpose
Fire Retardment
Water Repellency/ Waterproofing
Permanent Press
Stain Resistance
Mildrew/Rot-proof
There are hundreds of varieties of finishing techniques used throughout the world:
General Purpose FinishingSingeing – usually applied to cotton where the fabric is passed
over a gas flame to eliminate any loose fibre ends and produce a smooth fabric surface
Mercerising – the straightening of yarns to produce a more effective lustre
Carbonising – careful application of acid to a fabric, drying and then baking it – converts vegetable matter into charcoal which is easier to remove
Bleaching – chemical treatment of natural yarns to produce whiteness
Stentering – passing the fabric through a heated chamber to regulate length and width – this avoids skew and distortion
Special Purpose FinishingFire Retardment - a finish on fabrics to make them less flammable
Water Repelling– coating the fabric with a wax or metallic soap
Water Proofing – coating the fabric in a polymer emulsion that forms a film
Permanent Press – a coating that when cured leaves the fabric with long lasting creases resulting in easy care fabric
Stain Resistance – Scotchguarding protects the fabric from spots and stains
Mildew and rot-proof finish – protection from micro organisms
