Technical Abstract: Over the years there has been increasing interest in developing flame retardant (FR) cotton-based nonwovens. Whereas majority of the work has been done with high loft nonwovens, since this has been of interest to bedding and home furnishing industry, the effect of web density on flame retardancy is not studied. To investigate these effects, FR cotton composites were manufactured via, carding and thermal bonding. Carded webs were bonded via two different methods namely through-air bonding and hot calendaring. These webs with similar composition but different web density due to differences in bonding were investigated for their performance characteristics. The limiting oxygen index (LOI) for the samples did not show large differences. However, blend composition, method of bonding and fiber length showed the influence on burning mechanism of samples.
