ABSTRACT:
Hydraulic substances reinforced with high tenacity acrylonitrile (AN) fibers and a process for production thereof are provided.
The high tenacity AN fibers comprise AN polymers composed mainly of AN having an intrinsic viscosity of at least 2.5 and have an X-ray crystalline orientation of at least 93%, a tensile strength of at least 10 g/d, an initial modulus of at least 180 g/d, a contrast glossiness of at least 10% and a smooth surface.
Hydraulic substances reinforced with the high tenacity AN fiber are produced by uniformly dispersing in water, a hydraulic substance and the high tenacity AN fibers having applied thereto nonionic or cationic high molecular flocculants, adding anionic high molecular flocculants thereto to flocculate and adsorb cement particles onto the surface of the AN fibers and, subjecting the resulting slurry to paper-making.
