Abstract
A short fiber-containing down-feather wadding in which the short fibers are entangled in barbs of the down-feathers. In this wadding, the short fibers are uniformly mixed with the down-feathers, and the properties of the down-feathers, and the short fibers are effectively imparted to the wadding.
Claims6
A filling material comprising down-feathers mixed with short fibers, wherein the short fibers are entangled in barbs of the down-feathers and the short fibers are curled by heat-setting, obtained by
- (1) stirring short fibers and washed down-feathers in a mixing bath containing a surfactant-type softener to entangle the short fibers into barbs of the down-feathers, and
- (2) dehydrating and drying the entangled mixture, and then heat-setting the resultant mixture.
A filling material comprising down-feathers mixed with short fibers, wherein the short fibers are entangled in barbs of the down-feathers and the short fibers are curled by heat-setting, obtained by
- (1) stirring short fibers and washed wet down-feathers in a closed-type mixing bath containing a surfactant-type softener to entangle the short fibers into barbs of the down-feathers, and
- (2) dehydrating and drying the entangled mixture, and then heat-setting the resulting mixture.
