Three methods of rendering upholstery fabrics smolder resistant were evaluated by determining the rate and extent of percent weight loss of a small scale mock-up system when the fabrics, with and without treatment, were tested in combination with F.R. cotton batting, F.R. polyurethane foam and resinated polyester fiber batting. A lit cigarette was placed in the crevice formed by the abutment of vertical and horizontal panels. The three methods of treatment in cluded two types of backcoating and a methyl borate vapor phase treatment of the entire fabric.
In 1981 the Bureau of Home Furnishings began a study to evaluate the potential for cigarette ignition of residential upholstered furniture and to determine the percent of compliance with California's mandatory flammability regulations for materials used in upholstered furniture and the State's labeling requirements. This paper reports the results on the first 450 items of furniture. The presence of labels and compliance with California's Furniture Flamma bility regulations is compared by year. A summary of cigarette ignitions and open flame/smoldering performance of filling material is given. The effect of cover fabric weight and fiber content and type filling material on cigarette igni tion is discussed and the wide variety of material choices for cigarette ignition resistant residential upholstered furniture demonstrated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
