Description

technical field [0001] The invention relates to the technical field of fiber preparation, in particular to a circulating fluid dynamic spinning device and method. Background technique [0002] Hydrogel fiber is a new type of fiber with swelling performance, stimuli response performance, slow release performance and immobilization performance. It has a good application prospect in the fields of tissue engineering, biomedicine, textile and polymer materials. At present, the spinning methods of hydrogel fibers include microfluidic spinning, electrospinning, wet spinning and so on. [0003] Microfluidic spinning means that the fiber-forming solution uses its laminar flow characteristics to flow along the direction of liquid flow in the microchannel of the microfluidic chip without contacting the inner wall of the microchannel, and then extruded in the microfluidic chip to solidify into fibers. , and its curing methods include photopolymerization, double diffusion, etc. Compare...
