ABSTRACT:
A fabric conditioner composition is distributed on an air permeable sheet in such manner that the conditioner occludes interior interstitial spaces in certain region of the sheet to block airflow therethrough, and other regions of the sheet have interstitially open spaces, there being additional interstitial spaces in those other regions which are relatively smaller and which contain remanent conditioner.
