Abstract
This invention relates to filling material composed of crimped fibers joined together at one end with a high density, and having crimps located in mutually deviating phases, while the other ends of the fibers stay free, and a process for manufacturing such filling material. The filling material exhibits superior bulkiness and thermal insulation, since the recovery force or resiliency of the crimps located in mutually deviating phases causes the fibers to spread sufficiently to contain a large quantity of air among themselves.
