Wet-laid technology is based on a nonwoven production process inwhich the textile fibres are suspended in an aqueous medium, and arethen deposited on a conveyor belt that carries the nonwoven sheet tothe consolidation station.

The bonds between the fibers of the nonwoven aregenerated by the action of the temperature inside thedrying module, through the fusion of the thermo-meltingfibres in the veil.

4. CONCLUSIONS
Wet-laid technology allows to obtain technical non-wovens suitable to be implementedin composites manufacturing by means of compression and injection mouldingtechniques.
1
Very short fibres or even powder materials can be processed using wet-laid technologyin order to obtain technical non-wovens.2
Natural wastes find a huge variety of applications in technical non-wovensdevelopment. It is important to identify the optimum binder agent (thermoplasticmaterial to improve the mechanical properties of the non-woven). In addition, chemicaltreatments with compatibilizing agents could enhance the mechanical properties ofnon-wovens and subsequent composites obtained based on them.
3
Non-wovens and composites based on natural wastes can be successfully applied asacoustic insulation systems. Anyway, fire retardant treatments should be implementedin these ecological building products.
