PBO (Poly-p-phenylene benzobisoxazole) fiber, short for poly(p-phenylene-2,6-benzobisoxazole), is a high-performance synthetic fiber known as the “super fiber of the 21st century.” As one of the most advanced pbo fiber fabrics, its most outstanding characteristics are its extremely high mechanical strength and modulus, as well as excellent heat resistance and flame retardancy. It has become one of the most sought-after flame retardant fabrics in the flame retardant fabric market.
PBO fiber is usually supplied in filament form. Due to its high modulus and brittleness, spinning and twisting require specialized equipment and techniques to avoid fuzzing and breakage. Sometimes pretreatment, such as applying special sizing agents or oils, is used to improve weavability.
During warping, tension and alignment must be strictly controlled. Weaving is typically carried out on high-speed rapier looms or air-jet looms. Twill structures (e.g., 2/1 right twill or 2/2 balanced twill) form clear twill lines. Parameters like ends per inch and picks per inch are calculated to achieve 200 GSM and the desired twill structure.
