Abstract
A ball-shaped light heat generating fiber aggregate and a method for producing the same include a light heat generating material that is sprayed and applied to any one filament or a mixture of two or more filaments selected from the group consisting of a polyamide-based filament, a polyester-based filament, and a polypropylene-based filament, opening and mixing the same to separate the filaments, and producing a ball-shaped fiber aggregate.
