  Abstract

For the first time, an optimized twill ripstop woven structure having an areal density of 70 g/m2 has been introduced as an outer shell protective jacket that shows excellent mechanical strength (tensile, tear, and abrasion). A thorough study of different weave designs and areal densities on the mechanical strength of nylon 6 and nylon 66 woven fabrics was conducted. A new factor “RF” is introduced to predict the mechanical strength of weave designs more accurately than the conventionally reported factors: CFF (cross-over firmness factor) and FYF (floating yarn factor). In addition, the mechanical strengths of twill ripstop woven fabric laminated with PU, PTFE, and Bi-component PTFE membranes were studied. Water vapor transmission and air permeability of all laminated membranes were analyzed to achieve a balance between wearer comfort and foul conditions. The contact or accumulation of the outer fabric with different lubricants (kerosene and grease) was also considered, and tear behavior was studied. Based on the results, an optimized laminating membrane was selected for the outer protective shell.
