Abstract

The invention discloses a UV-curable electrospun colored micro-nanofiber stranded wire and its preparation method. Micro-nanofiber for being twisted into the stranded wire is colored. The micro-nanofiber contains a photo-curing polymer material and color phototherapy gel. The micro-nanofiber is prepared from a solvent-free electrospinning precursor solution. The electrospinning process is carried out in a mionectic UV-irradiation environment. The electrospinning precursor solution contains a liquid prepolymer of a photo-curing material, a photoinitiator and phototherapy gel, and contains no organic solvent. The stranded wire has rich and full colors, has good color fastness, is not easy to fade and has good tensile mechanical property. Meanwhile, there is no need to add an organic solvent during the electrospinning preparation process. The preparation process is safer and more environmentally-friendly. The preparation method is suitable for large-scale production.

Description

technical field [0001] The invention relates to a UV-cured electrospun colored micro-nano fiber stranded wire and a preparation method thereof, belonging to the field of nano-material preparation. Background technique [0002] All kinds of fibers, whether natural, man-made and synthetic, have their own advantages and disadvantages. Natural fibers are comfortable to wear, and it is relatively easy to print and dye various patterns and colors. However, except for cotton, like wool and silk, the output is not high and the price is relatively expensive; The strength in the state is low, so it is not durable without washing; synthetic fibers such as polyester are generally strong and wear-resistant, but they are not easy to dye and the price is relatively high. The fibers and fiber fabrics desired by people can be breathable, comfortable, washable and wearable, and satisfy the fancy colors. It is difficult for the existing technology to overcome the defect that the background c...
