Nonwoven Semi-finished Products and Nonwoven Production Technology

The properties of nonwoven-based semi-finished products are influenced much more significantly by their production methods than any yarn-based semi-finished products. Due to the multitude of available production methods, nonwoven semi-finished products offer a comparably specific and diversified property profile. In order to fully utilize this property potential of nonwoven-based semi-finished products for the characteristics of the composite material, basic knowledge of the combination between the structure and the characteristics of the nonwoven fabrics, in relation to various manufacturing methods is absolutely necessary. This chapter, beginning with the basic technological principles, reviews the combination of construction and structural as well as processing properties of the nonwoven semi-finished products in interaction with the manufacturing process. Conclusively, selected nonwoven-based lightweight construction solutions will be presented.
