Trutzschlers newest innovations in the field of Man Made Fibre technology
April 13, 2011 - Germany
Cotton like Fibres:
Trützschler Nonwovens has been able to increase line speeds on the Fleissner Fibre Lines:
• Ready to go for line capacity 300tons/day, with one-side roller suspension
• Line capacities >300t/day, with two-side roller suspension
Compact Tow Drawing consisting of Rollers with individual Torque Motors
The new Fleissner Tow Drawing Unit was recently developed and shows that Trützschler Nonwovens is Innovative on their Fleissner Fibre Line concepts. The advantages of the new system are:
• Less rollers for better performance
• More flexibility in adjusting fibre properties
• No wraps on rollers - higher production efficiency
• No gear boxes
• Compact - half length of conventional line
• Better heat transfer - less energy consumption
• Assembled unit on common platform
• Consistent torque of rollers, speeds up to 500m/min
• Economic for line capacities up to 80 tons/day
Newest innovations in the field of Nonwoven technology:
Double Roller Unit for smoothening and calibrating - Uniform line pressure, in combination with a uniform gap width, ensures optimal results
In our constant efforts to adapt the products of the Trützschler Nonwovens Group to the requirements of the market, the calender, the foam padder and the calibration unit of our production program have been redesigned. The target was to unify the double roller unit to a common constructional base and at the same time adjust the single aggregates to our customer’s needs today.
The result is a machine consisting of two rollers which can be used as a calibration unit, calender, foam padder, squeezing unit or printing unit. Depending on the requirements of the process the rolls can be installed horizontal or vertical. The diameter of the roller is chosen based on standard roll diameters according to the actual pressure needed and the process requirements. The pressure is generated pneumatically; an electro mechanical pressure generation is foreseen only for calibration units with special requirements.
Of course the rolls can be cooled, heated or cooled and heated. Where necessary the machine is equipped with a roller-bending-compensation-system.
Line pressure: 50 – 600 N/cm
Output: < 100 m/min
Working width: < 7,000 mm
Hydro Entangling in new applications
Trützschler Nonwovens have been active in developing new markets for hydro entangling and one of the new products are hot air filters. The mechanically pre-needled webs are finished with the Fleissner AquaJet resulting in better efficiencies and higher filter qualities due to smoother surface of the fabric. Also it is possible to reduce the weight of the filter media keeping the same filtration efficiency, which reduces the cost of the fabric.
There have been further developments with splittable fibers processed via an Erko pre needle loom and a Fleissner AquaJet. Samples will be presented.
Erko Needle Punching Lines
Erko has further advanced their needle looms by a high efficient suction system keeping the stripper plates clean and to improve the uptime especially on recycled fiber materials, which are more and more used in Nonwoven products.
Energy saving in thermal processes (drying & bonding)
Trützschler Nonwovens focuses its development work more and more on the reduction of energy costs. A modern line becomes even more efficient not only through an optimal line layout and by using highly efficient drive systems but in particular by additional energy recovery measures. Trützschler Nonwovens will present concepts for the reduction of the energy consumption in their own production lines.
