▎ 摘　　要

NOVELTY - The composite has an upper fiber layer and a lower fiber layer combined with each other on upper and lower parts of a middle fiber layer to form an integrated fiber composite. The intermediate fiber layer is formed of multi-filament single fibers in a sheet form. The upper and the lower fiber layers are made of hollow fiber single fiber. Mixed filament yarns are mixed with short fibers of construction and formed in the sheet form, where the composite utilizes 100 percent by weight of graphene polyester as a melt spinning raw material. USE - Multi-layered fiber composite for fillers containing functional hollow fibers. ADVANTAGE - The multi-layered fiber composite has excellent elasticity restoring power, light weight, heat preservation and heat insulation, antibacterial and deodorizing function due to nature of additive component, and far-infrared ray emission function similar to ocher, and can be used in wide range of applications as a filling material for blankets and bedding, interior materials for automobiles and building materials, as well as various products made of eco-friendly functional fibers. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a multi-layered fiber composite for fillers containing functional hollow fibers. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a multi-layered fiber composite for fillers containing functional hollow fibers(Drawing includes non-English language text). 10Spinning process 20Post-spinning treatment process 30Short fiber manufacturing process 40Carding process 50Mixed fiber process
