A heat treatment process for fiber feedstock, comprises repeatedly subjecting the bale to a reduced pressure atmosphere followed by the introduction of steam which permeates the bale. The interior of the bale may ultimately reach a temperature of about 80° C., which conditions and sanitizes the cotton fibers. Reduced pressure in the range of 20-200 mbar and steam treatment time in the order of 5 minutes can be employed.
