Steamer
Printed dyes are usually fixed by steaming processes, the steam providing the moisture and rapid heating that brings about the transfer of dye molecules from the thickener film to the fibre within a reasonable time. Historically, the process of developing printed mordants was known as ‘ageing’ and took a long time, as the term implies. Printed fabric was draped over poles and left in a room with a warm and humid atmosphere for some days, allowing the processes of diffusion and chemical reaction to occur. 
 
Steamer
The time and conditions for fixation in steam vary with the properties of the dyes and fibres used, ranging from 10 s to 60 min in steam at 200 to 100 °C.

Continuous steaming / curing / polymerising machine is the updated and technologically advanced version of a textile processing machine. In textile processing machine the steaming chamber is closed type made completely in stainless steel AISI 316. Fabric feed takes place through an opening on the front side whilst extraction is from the back side. The fabric is placed on rods and transported through the steaming chamber. The rods are rotating on their axis to avoid marking off from the rod itself. Loop formation is done by a dancing roller system.

For low temperature steaming the textile processing machine has a chamber roof which is heated by steam coils preventing condensation and drippings. Steam agers are equipped with special device, a Steam Saturator, which conditions the steam passes through the water before being injected into the steaming chamber. These particular characteristics of steam pre- conditioning which prevent and control the exothermic reaction of the fabrics and of the printing paste, make machine " UNIQUE" of its kind and are the basis of great success achieved all over in textile industries.

For high temperature steaming steam agers are equipped with efficient re-circulation system and heat exchangers using Thermic Fluid which ensures uniform temperature in the chamber. Special system to allow air to re-circulate instead of steam permitting polymerization treatment with hot air upto 160°C.
