Texturising or texturizing is the process by which
synthetic fibres are modified to change their texture - the physical appearance of the
fibre
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorpora ...

thermoplastic
A thermoplastic, or thermosoft plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.
Most thermoplastics have a high molecular weight. The polymer chains associat ...
fibres are twisted, heat set and untwisted), 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 (as processes like bulking allow it to trap air better), to minimise a shiny, synthetic-looking appearance, to reduce the silky nature of the fibre, or to create special effects (fancy yarns).
These modifications will also affect the eventual
fabric
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the ...
, and fibres may be folded, looped, coiled or crinkled in order to improve the drape, appearance,
luster, 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.
Texture
Texture in textiles characterises the surface as rough or smooth, which is determined by tactile and visual perception. The texture of textiles is affected by yarn manipulations,
finishing techniques, and fabric structures.

Aesthetics (textile)
Aesthetics in textiles is one of the basic concepts of serviceability of textiles. It is determined by the perception of touch and sight. Aesthetics imply the appearance and attraction of textile products; it includes the color and texture o ...
