Manufacture of Parachute Fabric with Specified Air Permeability from Aramid Yarns on Shuttleless Looms

Resumo

We have determined the optimal technological parameters for manufacture of parachute aramid fabric on looms of different designs. We have studied the effect of the basic operating parameters of the loom on the physical and mechanical properties of the fabric. We have established that the air permeability of parachute fabric can be considerably reduced due to buckling of the warp yarns when using droppers. We have worked up recommendations for manufacture of fabric with specified air permeability on a high-speed Dornier rapier loom, making it possible to improve the quality of the fabric and the productivity.
