AFC integrates graphene into the spinning process through advanced modification techniques, successfully developing graphene composite filament yarns with antibacterial and far-infrared heating properties. These yarns are widely applicable in home textiles, health care, performance apparel, and safety protection. They provide fabrics with functions such as far-infrared thermal insulation, moisture regulation, and enhanced blood circulation. Using a physical exfoliation method, the original characteristics of graphene are preserved, ensuring greater stability and long-lasting performance.
