Title
(EN) POLYBENZAZOLE FIBER AND USE THEREOF
(FR) FIBRE DE POLYBENZAZOLE ET SON UTILISATION
(JA) ポリベンザゾール繊維及びその利用
Abstract
(EN)
A polybenzazole fiber, staple fiber, spun yarn or woven or knit fabric, comprising an organic pigment contained in the fiber, the organic pigment being one having -N= and/or NH- in its molecular structure, such as any of perinone and/or perylenes, phthalocyanines, quinacridones and dioxazines, the organic pigment being highly thermally stable one whose thermal decomposition temperature is 200˚C or higher, the organic pigment being soluble in a mineral acid, which polybenzazole fiber, staple fiber, spun yarn or woven or knit fabric exhibits a strength retention, measured after exposure to xenon radiation for 100 hr, of 50% or higher and a tensile strength retention, measured after exposure in an atmosphere of 80˚C and 80% relative humidity for 700 hr, of 85% or higher. The polybenzazole fiber, staple fiber, spun yarn or woven or knit fabric can find application in a code for rubber reinforcement, a sheet or rod for cement/concrete reinforcement, a composite material, a sail cloth, a rope and a bullet and knife proof vest.
(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.
