AI Technical Summary
The dense scale layer structure of wool fibers leads to poor dyeing performance. Existing methods have problems such as environmental pollution, low efficiency, and reduced strength. Furthermore, fibers treated with traditional ionic liquids have no antibacterial ability.
An ionic liquid was prepared by reacting a compound X, CH3Br, and an aromatic hydrocarbon solvent in a specific ratio under an inert gas atmosphere. This liquid then formed hydrogen bonds with a bio-derived dye. The dye was then used to dye wool fibers, and the dynamic covalent bonds and other interactions promoted the directional adsorption of the dye.
This technology achieves high dyeing rates, high color fastness, and antibacterial properties in wool fiber dyeing, improving the mechanical properties of the fibers while reducing the risk of environmental pollution.
