Abstract

The morphology of layered NW fabrics has been studied in terms of fabric thickness (tL), packing density coefficient (ØL), fabric hardness (HL), and energy-absorbed index (bL). All these terms are obtained when the fabric is subjected to compression. For multi-layer NW fabric, energy-absorbed index was found to increase as fabric hard ness decreases. The product of fabric hardness and compression energy index for all tested NW fabrics is constant, i.e. Hb = 435. Also it was found that as the no. of layers increase the multi-layered thick ness and/or mass per unit area is increase While the packing density coefficient. of multi-layer NW fabric has minor differences between Øs and ØL .
