Wrinkle free finishing | Anti crease finishing

Causes of crease formation: Wrinkle occurs when the fabric is severely bent, H-bond between the molecular chains in the amorphous region of the fibre breaks allowing the chains to slip past one another. The bonds reform in new places and hold creases the fibre and fabric.

Principle of anti-crease finishing:

Resist to creasing is imparted to cellulosic fibers by resisting the slippage of molecular chains. Chair slippage can be restricted by adding chemical cross links between the molecular chains in amorphous resigns of the fibre or by deposition of polymeric materials in the amorphous regions.

Cross – linking of Cellulose is done at high temperature or dry fabric to impart crease resistance and dimensional stability to the fabric.
