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.
Claims6
A fabric conditioning means adapted for use in a clothes dryer to allow substantially unrestricted hot airflow to the dryer exhaust duct in all positions of said means in the dryer, said means comprising
- (a) a continuous and interstitially impregnatable air-permeable carrier sheet,
- (b) a fabric conditioner composition on the sheet,
- (c) said conditioner defining local substantially regularly distributed concentrations thereof impregnating and occluding interior interstitial spaces in certain regions of the sheet interior to block airflow therethrough, the sheet with said conditioner characterized as having greater air permeability at other sheet interior regions located adjacent to and between said concentrations than at said concentrations, said other regions of the sheet characterized by interstitially open spaces,
- (d) said interstitially open spaces in said other sheet regions characterized as relatively larger spaces from which said conditioner has been removed by fluid streams, there being additional interstitial spaces in said other regions which are relatively smaller and which contain remanent conditioner.

- (d) the permeability of said sheet resulting in a maximum of 15% to 18% reduction of dryer vent airflow velocity therethrough as compared with unimpeded dryer vent airflow velocity,
- (e) said interstitially open spaces in said other sheet regions characterized as relatively larger spaces from which said conditioner has been removed by fluid streams, there being additional interstitial spaces in said other regions which are relatively smaller and which contain remanent conditioner.
