AI Technical Summary
Existing technologies make it difficult to achieve efficient atmospheric pressure dyeing of plant dyes on synthetic fibers. Furthermore, traditional synthetic fiber dyeing processes suffer from insufficient environmental friendliness, inadequate biomimicry, difficulty in synergizing dyeing and function, and limitations in the application of plant dyes.
By introducing sulfonated graphene into polyester fibers and combining it with gradient etching, a biomimetic rough surface is constructed to provide binding sites for plant dyes, thereby achieving a synergistic improvement in high-efficiency dyeing under normal pressure and powder-grabbing performance.
It achieves efficient dyeing of plant dyes under normal pressure, improves the powder-grabbing performance and soft touch of the fiber, meets the requirements of green and sustainable development, and is suitable for the large-scale production of high-end cosmetic brushes.
