The Special Finishes for Natural Fibers are
given below:
1.
Bio-polishing: Bio-polishing removes the protruding fibers of a fabric
through the action of an enzyme. Enzyme, such as cellulose for cotton,
selectively removes protruding fibers. These enzymes may be deactivated by an
increase in temperature.
2.
Mercerization: Mercerization makes woven cotton fabric stronger, more lustrous,
to have better dye affinity and to be less abrasive.
3.
Raising: Raising lifts the surface fibers to improve the softness and
hand feel properties of the textile materials.
4.
Peach finish: Peach finish subjects the fabric (either cotton on its
synthetic blends) to emery wheels, making the surface velvet-like. This is a
special finish used mostly in garments.
5.
Fulling: Fulling is a method of thickening woolen material to make its
more water-resistant.
6.
Calendaring: Calendaring makes one or both surfaces of the fabric smooth
and shiny. The fabric is passed through hot, fast moving stainless steel
cylinders.
7.
Crease: Resist finish or wash and wear or wrinkle free finishes are
achieved by the addition of a chemical resin finish that makes the fiber take
on a quality similar to that of a synthetic fiber.
