Continuous pressing, setting and decatizing with the GFP-effect:
softer, more flexible and better shaping
What is decatising?
Decatizing (or decatising) mainly imparts
dimensional stability to the textile fabrics. Also creases are removed and the
fabric is smoothened. Here the principle involved is controlled relaxation of
strains stored in a fabric. Fabric along with a felt are rolled in open width
onto a perforated cylinder and subjected to super heated steam. Here it is
important that the wool felt used should not be so hard that the silk fabric is
not pressed flat.
Use: Wool and wool blends as well as synthetic fibres, e.g. in the automotive field, especially also for blends with viscose and cotton.
This is a continuous decatizer working with the evaporation system. Important is the defined and adjustable moisture application at machine entry. By the action of temperature and pressure the moisture applied is converted into
steam, an impermeable pressure belt prevents escaping of the steam. Fabric run throughout the machine is absolutely at minimum of tension. By heating pressure belt and effect cylinder and through the surface pressure produced by the tensioning
roller, HT conditions are achieved. The higher the pressure, the higher the fabric temperature – up to 140°C.
Conventional continuous decatizers work with the suction principle by which temperatures of only up to 105°C can be achieved. Touch, lustre, volume, degree of fixation and elasticity can be influenced within wide bounds through humidity,
temperature and pressure whereby the height of temperature is a decisive factor.
