Continuous decatizing machines
The DOLLFUS & MULLER felts are used on these machines. The woven woollen fabrics need to be decatized in order to obtain good dimensional stability and handle. The fabric passes between two felts under hot temperature and steam atmosphere. One of them, the product FINROLL, acts as a conveyor which carries the fabric inside the machine. The second is a heat shrinkable sleeve which fits on a perforated steaming drum. Both felts are necessary to improve the handle of the fabric.
The DOLLFUS & MULLER silicone coated felts are used on high pressure continuous decatizing machines. The woven woollen fabric is carried into the machine and strongly pressed against a hot cylinder. This mechanical action creates saturated steam which is necessary for the finishing of the fabric. The silicone layer acts as an impermeable shield, so that the steam is almost completely applied on the fabric. This kind of finishing gives a high dimensional stability and a very good handle to the processed fabric. These felts are used on the following machines : Sperotto Rimar, Kettling & Braun, Hemmer, Bisio, Biella Shrunk Process, M-TEC, Dhall,…

Semi-continuous or discontinuous decatizing machines
The DOLLFUS & MULLER satin wrappers are used on these machines. The woollen fabric is wrapped with the satin around a steam heated drum in lengths from 200 up to 1000 m. In most cases this roll goes into an autoclave for around a 15-20 minute cycle, and is unwrapped afterwards. The combination of the high pressure steam atmosphere and this wrapper gives a good handle to the fabric. These wrappers are used on the following machines : Biella Shrunk Process, TMT, Gessner,…

Steaming machines / Spongers Dryers
The DOLLFUS & MULLER conveyor belts are used in order to convey the woollen fabrics inside these machines. This machine improves handle and creates shrinkage to the woollen fabrics using steam. These belts can also be used at the exit of the discontinuous and continuous decatizing machines, in order to assist the fabric to exit the machine and to be cooled. These conveyor belts are used on the following machines : Sperotto Rimar, Biella Shrunk Process, Stalam, Krantz,…
