It also enables the manufacturing of disposable cleaning wipes from 100% biodegradable materials. Voith’s HydroFormer has been specifically optimised for the formation of wet-laid nonwovens. With more than 70 successful installations, the HydroFormer has gained worldwide acceptance.
Benefits of the HydroFormer
- Cost effective use of raw materials
- Renewable materials used exclusively
- Considerable minimisation of fibre losses due to re-use
- Simple one step manufacturing of multi-ply products
- Extensive flexibility in raw material use
AquaJet for spunlacing from Truetzschler Nonwovens
After the web is formed in the HydroFormer, it needs to be bonded to add strength and function. It is in this bonding step that the know-how from Truetzschler is applied. Web bonding is performed with the help of the AquaJet. In this field, Truetzschler Nonwovens draws on its extensive experience of more than 100 projects running worldwide.
Compared with other web bonding methods, the AquaJet spunlacing process does not use chemical binding agents or bicomponent fibres but relies only on the momentum of water jets to entangle the fibres with one another. Continuous high-pressure water jets strike the loose nonwoven web, which is moved through on a belt underneath the water bar, while suction fans remove the water used. The bonding increases tensile strength and lends the material the soft feel of a textile. Structures and perforations can also be created, if required.
Benefits of the AquaJet
- Use of environmentally friendly and inexpensive raw materials
- Produces soft nonwovens
- Natural bonding process using water only
- High savings potential – thanks to optimised pump and vacuum performance
- Integrated system for excellent nonwoven quality
In harmony with the environment
Apart from short fibres being used, the Voith-Truetzschler process avoids the use of chemical binders to bond the web formed. This reduces the raw material cost for making nonwovens. Compared to oil-based materials like PET/PP fibres, cellulose fibres do not burden the environment after use. Wipes produced entirely from these degradable fibres in a customised wet-laid spunlacing process can therefore be conveniently flushed down the toilet.
Both the AquaJet and the HydroFormer have been developed with water conservation in mind. The water from the process is filtered via a shared water cycle with downstream production steps, and then treated and returned to the manufacturing process. Flushable products must pass a defined test sequence developed by INDA and EDANA, the North American and European nonwovens associations.
