SAIL FABRIC Russian patent published in 1996 - IPC

FIELD: textile industry. SUBSTANCE: fabric is made of regularly alternating polyethylene and polyaramide fibers with similar material = 32:1 by warp and (3:2)-(3:1) by weft. Every twisted warp fiber has twisting direction opposite to twisting direction of spun warp and weft polyaramide fibers. Every twisted warp or weft polyaramide fiber is made of two strands - complexed fibers at the diameter ratio of complexed and a single thread in the every strand = (295-300):1. Twisting direction of every spun polyaramide fiber is similar with that of every complexed polyaramide fiber. Slope angle of complexed polyaramide fibers to the axis of spun polyaramide fiber = 43-51 degrees. EFFECT: increased deformation modulus and form-resistance, decreased rupture elongation by warp and at rupture at angle 45 degrees, low water absorption and buoyancy.
