(DE) POLYBENZAZOLFASER UND DEREN VERWENDUNG
(EN) POLYBENZAZOLE FIBER AND USE THEREOF
(FR) FIBRE DE POLYBENZAZOLE ET SON UTILISATION
Abstract
(EN)
The present invention relates to polybenzazole fibers or filaments, staple fibers, spun yarns, and woven or knitted fabrics containing in themselves an organic pigment having heat resistance as high as a thermal decomposition temperature of 200 DEG C or higher, and soluble in a mineral acid and having group(s) of -N= and/or NH- in the molecule, such as any of perinones and/or perylenes, any of phthalocyanines, any of quinacridones, and any of dioxazines, wherein they have a strength retention of 50% or higher when exposed to light from a xenon lamp for 100 hours and having a tensile strength retention of 85% or higher after exposed to an atmosphere of a temperature of 80 DEG C and a relative humidity of 80% for 700 hours. The polybenzazole fibers or filaments, staple fibers, spun yarns, and woven or knitted fabrics can be used for cords for reinforcing rubber, sheets and rods for reinforcing cement/concrete, composite materials, sail clothes, ropes, knife proof vests and bullet proof vests.

(FR)
L'invention concerne une fibre de polybenzazole, une fibre discontinue, un filé de fibres, une étoffe tissée ou une étoffe à mailles, contenant un pigment organique présent dans la fibre, ledit pigment organique présentant une structure moléculaire de type -N= et/ou NH-, correspondant par exemple à n'importe quel composé suivant: périnone et/ou pérylènes, phthalocyanines, quinacridones et dioxazines. Ledit pigment organique présente une grande stabilité thermique, sa température de décomposition thermique étant supérieure ou égale à 200 °C, et il est soluble dans un acide minéral. Ladite fibre de polybenzazole, ladite fibre discontinue, ledit filé de fibres, ladite étoffe tissée ou ladite étoffe à mailles, présentent une conservation des propriétés de résistance, mesurée après exposition à rayonnement de xénon pendant 100 heures, supérieure ou égale à 50 %, et une conservation de la résistance à la traction, mesurée après exposition à une atmosphère de 80 °C et une humidité relative de 80 % pendant 700 heures, supérieure ou égale à 85 %. Ladite fibre de polybenzazole, ladite fibre discontinue, ledit filé de fibres, ladite étoffe tissée ou ladite étoffe à mailles, peuvent être utilisés dans un câble de renforcement de caoutchouc, une couche ou une tige pour le renforcement de ciment/béton, un matériau composite, une toile à voile, une corde et un gilet pare-balles et résistant aux objets tranchants.
