A method of manufacturing stabilized, fluffy batts of individualized fibers by treating the surfaces of dense batts of fibers with materials which will react with each other on contact or which can be caused to react with each other by subsequent treatment. The treated dense batt is comminuted or ground to individualize fibers and the fibers collected in the form of a fluffy batt. The materials react with each other on contact or the fluffy batt may thereafter be teated to cause the materials to react. The resulting product is a lightweight, fluffy batt of individualized fibers having reacted materials uniformly distributed throughout the batt to provide the batt with the desired final properties, such as resiliency, absorbency and bulk in a stabilized state.
