Abstract
Calendering is programmed finishing technique in the textile industry where the texture is squeezed between two or more rolls with a goal to obtain desired fragile quality, radiance and translucency. The essential guideline of calendering is to open the material to the joined impact of dampness, warmth and weight until the point texture gains an extraordinarily smooth and light reflecting surface. The essential mechanical action of the rolling calender is to cause the fibers of the web to reshape and deform around one another to get the desired smoothness. In this examination, an attempt has been made to develop a non-Hertzian nip mechanics model for finding the contact width of rolling calender and simulate this model to explore the impacts of design and process parameters such as load applied, bulk modulus, bonding time, diameter of the roll and cover thickness on contact width.
