摘要

Needle punched jute non-woven samples were prepared changing the needle gauge, punch density and depth of needle penetration. Surface appearance or the tracking of the needle punched non-woven fabric was evaluated by visual inspection and grading technique. Tensile properties of the-non-woven fabrics was also measured on an Instron Tensile Testing, Machine. From the results of tensile behaviour and surface appearance of the fabric, it was concluded that almost trackless fabric can be made with 250 punches/cm~2, 8 mm depth of needle penetration using 30 gauge needle Fabric with maximum tracking was noted at 200 punches/cm~2, 12 mm depth of needle penetration and 21 gauge needle.
