ABSTRACT:
A laundering aid having a core member, such as an elastomeric ball member, that includes a covering comprising an abrasive or brush-like material adapted for engaging and lifting matter, such animal hair, adherent to the surface of fabric articles when the laundering aid is placed into contact with clothing and other fabric articles within an operating tumble-type clothes dryer. The covering may further include a second material comprising a material that substantially lacks characteristics for lifting matter from other fabric, the first material being disposed adjacent to or over the first material to form a series of discrete sections having different properties that facilitate the dislodgement and or removal of the hair or other fine matter. The exemplary elastomeric ball member may be inflated for shape retention, while allowing for expansion when heated during the drying cycle. An exemplary method for using the laundering aid comprises the steps providing a laundering aid comprising a brush-like or abrasive outer covering adapted to engage and lift adherent matter and introducing the device into a tumble-type dryer with one more fabric articles, then operating the dryer until the adherent matter on the fabric articles has been substantially dislodged and vented from the drying chamber.
