Abstract
The compressional properties of needle punched non-woven fabric could be predicted from the thickness-pressure relation ship. The thickness-pressure equations found by Bogaty and Solove'ev for woven fabrics. were also found suitable for needle punched non-woven fabrics, for pressure ranges between 0.2 and 104.2 g/cm2. The final incompressibility coefficient B and the compression energy coefficient obtained from Solovele's and Bogaty's equations are well related to fabric hardness. A new equation in the form of; t = 1.167 t0.6 -0.167 t104.2 , could be used to calculate the thickness at zero pressure. Also it was found that fabric softness and fabric compressibility are well related to each other.
Keywords
