Abstract (en)
[origin: WO9006229A1] The invention resides in a nonlinear aromatic polyamide fiber having a reversible deflection greater than 1.2:1 when measured at ambient temperatures, a variation of fiber diameter not more than 15 percent at the bends or crimps of the fiber, and a bending strain value of less than 50 percent, and the method of preparing said fiber.
Abstract (fr)
On décrit une fibre non linéaire de polyamide aromatique dont la flexion réversible est supérieure à 1,2:1 lorsque mesurée à températures ambiantes, dont le diamètre ne varie pas de plus de 15 pour-cent aux coudes et plis, et dont le taux de déformation en flexion n'excède pas les 50 %; ainsi qu'un procédé de préparation de ladite fibre.
