Abstract
The present invention is directed to regulating agglomeration of elastic material (e.g., elastic strand) by regulating exposure of the material to water or water vapor. In some versions of the invention, regulating agglomeration in this way decreases, minimizes, or eliminates strand breaks on a production machine using the strand as raw material. Representative embodiments encompass regulating the material's exposure to water or water vapor by regulating temperature, humidity, or both around the elastic material, or containers containing the elastic material, so that the elastic material remains substantially unagglomerated. Other representative embodiments encompass packaging the elastic material in a way that regulates the material's exposure to water or water vapor so that the material remains substantially unagglomerated.
