Abstract
A sized staple fiber product that disperses quickly, thoroughly and uniformly in water is particularly useful in the manufacture of gypsum board by the slurry process. An aqueous chemical size composition on the surface of the fibers contains a high level of surfactant and can contain a polymer film former and a biocide. Preferably, the fiber is chopped glass fiber. Novel sizing composition and methods of making and using the fiber are also disclosed.
