Calendering Textiles may be defined as the modification of surface of fabric by the action of time, temperature, pressure and dampness. The finish is obtained by passing fabric between heated rotating rollers, when both speed of rotation and pressure applied are the variables.
There are different types of textile finishes. Among them calendaring is a mechanical finishing process. You can definitely beautify your fabric by calendaring.
Without any further due, let’s find out the calendaring process. Wanna know how is it done?

The effect of calendering is achieved by ironing. Ironing makes the fabric crease free. Not only calendaring process makes the fabric crease-free but also it does a lot-
Provides highly lustrous appearance on the fabric surface.
Provides smooth, glossy and silky touch to the fabric.
Increases fabric cover factor
Compress fabric and reduce thickness
Causes a closing to-gather of the threads by flattening them & thus tending to fill up the inter stiches between warp and weft.
Reduce air permeability by changing its porosity
Increase opacity of fabric
Reduce yarn slippage
Consolidation of non-woven
When wet process is carried out on fabrics, the fabric loses its luster and remains at creased form. To compensate this problem, calendering is carried out.
