Abstract
Heat activated, fabric conditioning products comprising a thick, absorbent substrate impregnated with fabric-conditioner chemicals are suitable for use at elevated temperatures encountered in laundry dryers. Prior to being used, such products tend to be stiff and boardy because of the brittle, wax-like properties of the fabric conditioner chemicals at ambient temperature. The stiff, boardy properties are substantially eliminated by temporarily compressing the thick impregnated substrate to less than 70% of its original thickness.
