What are the goals of the calendering process?

The definition provided in the presentation outlines calendering as the process of applying controlled temperature and pressure to compress fabric between rollers. The ultimate goals of this procedure are enhancing the fabric's drape, decreasing its thickness, boosting opacity, lowering air permeability, and achieving a lustrous finish. Date: November 6, 2021.

At what thermal level does a calendar roll operate?

A friction calender is capable of functioning at velocities reaching up to 35 yards per minute, featuring a nip loading that can go as high as 2500 PLI, with the typical range being around 1500 PLI. Both rolls, the upper and the lower one, undergo heating processes; specifically, the top roll is heated to temperatures ranging from 175°C to 215°C, whereas the bottom roll is heated to a temperature not exceeding 65°C to 120°C.
