[0049] The present invention first provides a method for preparing a temperature-adaptive humidity-controlling and temperature-regulating fabric, comprising:
[0050] The LCST type polymer material and the UCST type polymer material are respectively cross-linked on both sides of the fabric to form an inner coating layer composed of the LCST type polymer material and an outer coating layer composed of the UCST type polymer material.
[0051] Specifically, the inner coating refers to the side of the fabric that is close to the body when worn after being made into clothing; the outer coating refers to that after the fabric is made into clothing, it is far away from the body when worn. side of the body.
[0052] Specifically, the LCST type polymer material refers to a polymer material with a lower critical phase transition temperature (LCST), and the LCST type polymer material is at a temperature higher than the lower critical phase transition temperature (LCST). Hydrophobic, hyd...
Embodiment 1
[0118] (1) Immerse cotton fabric in solution I for hydrophobic and double bond modification (75°C, 4h);
[0119](2) After the reaction, the material was taken out and treated at high temperature under vacuum (105°C, 24h);
[0120] (3) after the reaction finishes, the material is taken out, a certain amount of solvent II is added for repeated washing and vacuum drying;
[0121] (4) the material obtained in step (3) is fixed on the rotating shaft, and the solution III is sprayed under the assistance of high-speed rotation (2000rpm) and hot air blower;
[0122] (5) After spraying, the material is removed, and the sprayed surface is subjected to ultraviolet light curing treatment (365nm, 200W, 45min) in a nitrogen environment;
[0123] (6) the material obtained in step (5) is added to solvent IV for repeated washing, and vacuum drying;
[0124] (7) the material obtained in step (6) is flipped and fixed on the rotating shaft, and the solution V is sprayed to the other side under ...
