The polyurethane fiber has excellent characteristics of excellent rebound resilience and the like, is the reputation of textile monosodium glutamate-like fiber, and can improve the performance of the fabric and the grade of the fabric by only adding a little spandex (the mass fraction is 2-25%). With the development of chemical engineering, chemical fiber and textile technology, the application field of the fiber is continuously widened, and the fiber is one of typical shape memory fibers. Usually, the fiber is prepared by wet spinning or dry spinning, but the preparation process needs a large amount of solvent, and the energy consumption for material conveying is large; the reactive spinning is to prepare polyurethane prepolymer, then add solvent to prepare solution, then carry out chain extension and solidification in a coagulating bath through a spinning nozzle, wherein the coagulating bath is composed of diamine or diol and solvent, and the diamine or diol and silk liquid undergo chemical reaction to accelerate the solidification speed, so as to form the polyurethane elastic fiber with a three-dimensional structure. The diamine or the diol has strong volatility and is easy to cause environmental pollution, so that the application of the diamine or the diol is limited.

In the step S1, the solution B is composed of polyethylene glycol and toluene, and the mass ratio of the polyethylene glycol to the toluene is 1:7-1: 10.
Further, in the step S1, the molar ratio of the diphenylmethane diisocyanate in the solution a to the polyethylene glycol in the solution B is 2:1-2.2: 1. The dripping time of the solution B is 0.5h, and the continuous reaction time is 1.5-2h after the dripping of the solution B is finished.
Further, in the step S1, the molecular weight of the polyethylene glycol is 1000-4000.
In step S2, the water-based reaction medium is prepared from Dimethylformamide (DMF) and NaHCO3Or a mixture of any of ethanol and water, wherein DMF or NaHCO is used3Or the mass mixing ratio of the ethanol to the water is 10:90-15: 85.
Therefore, in the step S2, the prepolymer extruded from the spinneret orifice reacts with the water-based medium at 10-30 ℃ for curing and forming, and the filament is dried and wound by infrared rays to obtain the intelligent responsive fiber.
The invention simultaneously claims the phase-change temperature-regulating functional and temperature-responsive fiber prepared by the method.
In the invention, diphenylmethane diisocyanate is selected as a reaction raw material for synthesizing polyurethane, and mainly has the function of reacting with polyethylene glycol to form a polyurethane prepolymer, and a hard chain segment of a polyurethane macromolecule is formed after chain extension. The function of toluene in the present invention is: as solvent and water-carrying agent in the reaction process. The dibutyltin dilaurate has the functions in the invention: as a catalyst for polyurethane synthesis. Polyethylene glycol is a phase change material, and the polyethylene glycol firstly reacts with diphenylmethane diisocyanate to form a prepolymer, and then a chain is extended to form a soft segment. The phase change enthalpy and the phase change temperature of the phase change polyurethane can be effectively controlled by limiting the molecular mass of the polyethylene glycol to be 1000-4000.
Has the advantages that:
the invention provides a method for preparing an intelligent fiber material with temperature response, shape memory and temperature regulation functions by using an aqueous solution to replace a traditional chain extender diamine or diol as a chain extender and adopting a reaction spinning method. Compared with the prior art, the method has the characteristics of simple operation, energy conservation, environmental friendliness and the like.
