Nepco technology

Composite nonwoven structures composed of two parallel layers kept at a distance apart can be made by the 3D Web Linker from Laroche, France. This is based on the Nepco Technology shown in Figure 8.12. The two feed webs are linked by vertical fibres generated through needling. The final product is essentially a spacer fabric with a largely hollow centre between the two face webs. This can be further processed to make a variety of composites (Le Roy, 1995 Poillet and Le Roy, 2003). The hollow space may also be filled with other filling materials. Nonwoven spacer fabrics can also...
