INDUSTRIAL FABRIC Russian patent published in 1995 - IPC

FIELD: parachute equipment. SUBSTANCE: nondimensional parameter Hredtot

reduced coefficient of total filling characterizing fabric structure with respect to air permeability is established. Relation between reduced coefficient of total filling and parameters of fabric made of complex threads is given in invention description. When Hredtot is not less than 3.5 and warp linear density-to-weft linear density ratio T_o/Y_y is not less than 1.2, industrial fabric features its service characteristics. EFFECT: reduced weft density in fabric with preserved air permeability. 5 dwg
