COMBI K13, the multifunction felt calender.
The sublimation printing on synthetic fabrics with transfer paper is a very simple technique, without the use of chemical products, with reduced investments, with the advantage of not requiring specific fabrics preparation and not requiring traditional post-printing treatments, such as steaming, washing and drying.
The process consists in the hot passage (200° C. for about 30 sec.) of fabric and transfer paper between the felt and the hot cylinder of our "Combi" calenders, the disperse sublimation dyes, which form the design on the paper, by the effect of the temperature are transformed into gas which is permanently fixed to the synthetic fibers of the fabric without additional treatments.
The felt calender is the perfect machine for this process due to its characteristic of having a long contact time between felt and cylinder which allows to develop a good production speed even with long permanence times.
The combination of temperature and pressure, with the easy availability of thermo-fusible materials, makes it possible with this machine to laminate two or more fabrics together with the simple passage in the calender of the various materials with excellent results in terms of adhesion, high speed and extreme ease of exercise.
With the "K13" version, an evolution of the previous "K1" and "K3", the "Combi" calenders now have the advantage of exerting a strong pressure (14,500 kg per 70 kg/lcm) obtained from the pressure cylinder, and of permanence in temperature between felt and cylinder which makes it possible to apply metallic and fancy foils on fabrics of any fiber, with excellent production speed and ease of use.
By exploiting the combination of the long contact time of the felt and the strong pressure of the "K13" cylinder, we have achieved the excellent result of transfer printing, coupling two or more fabrics and metallising fabrics at high speed, with high quality and soft hand, with reduced consumption, space and investments and all with a single machine, the “Combi K13”.
Our production program includes calenders with different diameters and different working widths to satisfy any production need of our customers.
