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.
Claims13
In the method of manufacturing a heat-activatable fabric conditioning product comprising impregnating an absorbent substrate having a thickness of at least 0.05 centimeters with at least 0.3 grams per cubic centimeter of a liquid fabric conditioning chemical followed by solidifying the fabric conditioning chemical on the substrate, the improvement which comprises;
- subjecting the absorbent substrate having the solidified fabric conditioning chemical impregnated therein to a compressive force of sufficient magnitude to reduce the thickness of the impregnated substrate to about 70% or less than 70% of its original thickness followed by relieving the compressive forces.
