The tensile strength and thickness compressibility of needle punched fabrics are important criteria for their filtration, absorption, and insulation performance. Researchers investigating how the manufacturing parameters of needle punched jute fabrics influence mechanical properties determined the effects of basis weight, needling density, and blend percentage on fabric tenacity, breaking extension, structure anisotropy, and thickness compressibility. An increase in fabric weight reduced the thickness compressibility of needle punched fabrics due to the consolidation of the fabric structure and an increase in the number of fibers per unit volume. Optimal needling density was 200 punches per square centimeter for 517-538 grams per square meter fabric. Beyond optimal density, fabric loops broke and thickness increased. Jute/polypropylene fabrics were thinner than were 100 percent jute nonwoven fabrics at a given needling density and fabric weight. 5 refs.
