WHAT IS A TEXTIL CALENDER?

A textile calender is a machine that performs the function of printing a special paper for sublimation onto a fabric. What the sublimation calender does is do the sublimation process. This process is done by means of heat and pressure, in this way the ink that is in the paper, by means of the heat evaporates and goes from a solid to a gaseous state, generating the sublimation process and penetrating the white fabric.

The calender consists of three rollers, which drag the fabric and make it pass at a constant pressure, through a heated mat by means of a cylinder filled with hot oil (+/- 200ºC). As the fabric and paper pass together between these rollers, the sublimation process happens.
The sublimation calenders can work in two different ways:

Roll to roll or cut garment
When what we are going to sublimate is a roll of fabric, we will use the system called roll to roll, this system is widely used by manufacturers of clothing, curtains, flags, etc.

The design created on the computer passes to the paper roll by means of a printing plotter and once the entire paper roll is printed, we can take it to the calender to transfer it to the fabric roll and ready to be cut and sewn.

Cut garment

The cut garment calenders have a built-in work table, the system is the same. A roll of paper with the drawings of the patterns made, but in this case it will be a worker who will position the pieces of white cloth on top of the drawing of the paper so that together they pass through the roller and are sublimated. This method is used by manufacturers of sportswear, masks, etc. Once sublimated, only the stitching of the garment remains.

There are two types of calender: roll-to-roll calender or multi-function calender that allows both roll-to-roll and cut garment work.
