Dial Patents Reusable Antistatic Dryer Products
US Patent No. 8,188,031 B2; The Dial Corporation has patented a dryer product that imparts antistatic properties to textiles. It is comprised of a water-insoluble, moisture-permeable, enclosed container, adapted to be removably placed within the drum of a dryer for contacting with the textiles during a drying cycle; and a compound within the water-insoluble, moisture-permeable, enclosed container. The compound comprises a material that is a desiccant adapted to absorb moisture from textiles during the drying cycle; an antistatic agent; and a material that, after absorbing moisture from the textiles during the drying cycle, solubilizes and evaporates from the water-insoluble, moisture-permeable, enclosed container upon application of heat to the container during the drying cycle. The water-insoluble, moisture-permeable, enclosed container contains a sufficient amount of the compound such that the dryer product can be used for more than one drying cycle while still imparting antistatic properties to the textiles being dried so that static electricity produced during each of the more than one drying cycle is no more than 10 kilovolts.
