Calendering for cotton and blended fabrics gives the fabric a flatter, shinier appearance or
a "chinz" effect, exerting pressure on the fabric by passing between two or more cylinders.
The cotton calender is made up of at least one heated cylinder (with diathermic oil or steam) and cylinders that can rotate with variable speeds different from each other.
The appearance obtained on the fabric depends on the material (synthetic, cotton, paper, etc.) that covers the cylinders that work with the rectified tempered steel cylinder or in pairs with each other.
In a three-roll calendering process, the fabric, packaged in large rolls or stacked on pallets, placed at the front center of the machine, passes:
through a fabric tensioner (see figure A, point 1), by a metal detector (fig. A, 2) which, if it detects metal elements in the fabric, stops the machine, between return cylinders, another tensioner (fig. A , 3) and to a fixed expander (fig. A, 4).
Then the fabric arrives at the calendering unit which is made up of a central heatable steel cylinder (fig. A, 5), a lower cylinder (fig. A, 6) and an upper one (fig. A, 7), both coated with different materials depending on the effect to be obtained on the fabric.
The lower and upper cylinders are controlled independently of each other so, during its path, the fabric can undergo two different pressures on the central cylinder.
The fabric is then collected in a large roll (fig. A, 8), but some machines are also equipped with a folding machine.
The duties of the employee are:
set and check the following processing parameters on the control panel:
pressure,
heated cylinder temperature,
rotation speed of the cylinders which can be adjusted differently for the cylinders, up to
create a certain friction on the fabric;
compare the first meters of calendered fabric with the reference sample, and possibly
modify the processing parameters;
check that the incoming fabric is well stretched and does not have any creases.
Creases on the fabric, due to calendering of the overlapping piece and not well expanded.
Areas with small, very dense folds, especially near the lateral areas, due to differences in tension on the piece being worked on.
After the sale of the machinery, we also assist you in logistics and, if desired by the customer, we have technicians capable of reassembling and starting up the machinery.
