Abstract
Abstract An article of manufacture is disclosed comprising a mattress edged with a novel heat barrier mattress tape edging. A method is also disclosed for manufacturing a heat barrier fabric containing at least about 50% by weight of filament yarn and, optionally, the balance spun yarn, the filament yarn and spun yarn being made from a synthetic fiber forming polymer such as a poly(ethyleneglycol terephthalate), where the loft of such fabric is the ratio of the average thickness of the fabric to the average combined thickness of such yarn and is from about 2.5 to about 4.5 to one and said fabric is from about 6 to about 20 ounces per square yard based on said poly(ethyleneglycol terephthalate). Spun yarn is used in the preferred embodiment. A process is also disclosed for making combustible mattress filling materials less susceptible to combustion when used adjacent to said fabric. The preferred embodiments comprise such fabric as a substantially woven mattress tape edging article of manufacture and the use of such tape edging in the aforementioned mattresses. In a further embodiment a non-synthetic fiber is used in the spun yarn such as cotton.
