This invention relates to a layered high loft flame resistant batting comprising a base layer and an outer layer and an article such as a mattress containing such batting. The base layer of the batting comprises 30 to 80 parts by weight heat resistant fibers, 5 to 55 parts by weight of a cellulose fiber that retains at least 10 percent of its fiber weight when heated in air to 700°C at a rate of 20 degrees C per minute, and a first binder material. The outer layer comprises a second binder material and up to 85 parts by weight of a fiber that is either (i) a cellulose fiber that retains at least 10 percent of its fiber weight when heated in air to 700°C at a rate of 20 degrees C per minute, (ii) a modacrylic fiber, or (iii) mixtures including these two fibers. In the high loft batting, the base layer comprises 20 to 70 parts by weight and the outer layer comprises 80 to 30 parts by weight, based on the total weight of those two layers, and the batting has a total thickness of 0.5 inches (1. 25 centimeters) or greater. |
