摘要:
A warming product that contains an exothermic composition configured to generate heat in the presence of oxygen and moisture is provided. The exothermic composition is applied to a thermal composite containing two or more fibrous layers, which are structured to provide enhanced distribution of the exothermic composition through the thermal composite structure. For example, a first fibrous layer may rapidly acquire the exothermic composition and distribute it primarily in the −z direction (direction of thickness) to a second fibrous layer, which may then distribute the exothermic composition primarily in the −x and −y directions. Typically, at least a portion of the exothermic composition is able to flow through the second fibrous layer and contact additional layers. For example, the exothermic composition may contain a moisture-holding layer configured to supply moisture to the exothermic composition. This places the exothermic composition into close contact with the moisture-holding layer, which may provide enhanced heating efficiency. Further, the exothermic composition may also adhere the moisture-holding layer to the composite without the need for additional bonding mechanisms.
