Abstract

The present invention relates to the technical field of functional fiber preparation, and provides a functional fiber preparation device and method, the functional fiber preparation device at least comprises: a hot drawing structure suitable for drawing a preform into a to-be-pressed fiber; the pressing structure comprises a pressing roller and a driving device, the surface of the pressing roller is provided with a micro-nano structure, and the feeding end of the pressing roller corresponds to the discharging end of the hot drawing structure; and the driving device is connected with the pressing roller and is suitable for driving the pressing roller to rotate so as to press the to-be-pressed fibers into target fibers with micro-nano structures on the surfaces. According to the preparation device of the functional fiber, the preform is subjected to wire drawing operation through the hot drawing structure, so that the fiber to be pressed is formed; and pressing the to-be-pressed fiber by adopting a pressing roller with a micro-nano structure on the surface so as to form a target fiber with a micro-nano structure on the surface. Waste gas and waste water are not generated in the preparation process, so that the influence on the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of preparation of functional fibers, in particular to a preparation device and method of functional fibers. Background technique [0002] The surface of micro-nano structure can endow materials with many excellent properties, such as hydrophilic and hydrophobic, antibacterial and structural color, etc. Therefore, studying a method to prepare controllable micro-nano structures on the surface of fibers has important practical significance for expanding the application scenarios of fibers and promoting the development of smart fabrics. [0003] In the prior art, when preparing fibers with micro-nano structures on the surface, phase separation methods are generally used, such as solvent evaporation method and solid phase separation method. For example, in the patent CN110528095A "a preparation method and device for porous surface structure fiber", it is proposed that the polymer melt is stretched into superfine...
