Texturizing
Texturising or texturizing is the process by which synthetic fibres are modified to change their texture - the physical appearance of the fibre. Texturising techniques can include bulking, crimping and coiling, amongst others. Texturising takes advantage of the thermoplastic nature of synthetic fibres, and uses it to set texturised features in place.
Fibres may be texturised to improve the fibre's insulation properties, to minimise a shiny, synthetic-looking appearance, to reduce the silky nature of the fibre, or to create special effects.
These modifications will also affect the eventual fabric, and fibres may be folded, looped, coiled or crinkled in order to improve the drape, appearance, lustre, warmth, elasticity or handle of the finished fabric. Texturising can reduce the "synthetic" appearance of a finished fabric, bringing its appearance closer to that of a natural fibre fabric.
