Abstract
A method of manufacturing a water-repellent, fluffy lightweight batt of wood pulp fibers comprising applying a water-repellent material to a surface of a dry wood pulp board so that the water-repellent penetrates through only a portion of the board. The treated board is ground to individualize the fibers, and the ground fibers are collected in a batt with the water-repellent treated fibers distributed uniformly throughout to produce a fluffy, water-repellent batt of wood pulp fibers.
