preparation example Construction

[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...

Abstract

The invention provides a temperature-adaptive humidity-controlling and temperature-regulating fabric and a preparation method thereof. The preparation method of the temperature-adaptive humidity-controlling and temperature-regulating fabric includes: in-situ cross-linking the LCST-type polymer material and the UCST-type polymer material on both sides of the fabric, respectively, to form an inner layer composed of the LCST-type polymer material. Coating and outer coating composed of UCST type polymer material. In the present invention, by in-situ cross-linking of two temperature-sensitive polymers with opposite responsiveness on both sides of the fabric, reversible water conduction can be realized when the temperature changes, so as to achieve the effect of humidity control and temperature regulation.

Description

technical field [0001] The invention relates to the field of fabric preparation, in particular to a temperature-adaptive humidity-controlling and temperature-regulating fabric and a preparation method thereof. Background technique [0002] Clothing with the ability to adjust temperature or humidity, as an "air conditioner" material that is in close contact with humans, can adjust the microenvironment and comfort of the body surface in a personalized, small-scale, and flexible manner, replacing the use of large-area air conditioners. Sustainable development is of great significance and is one of the research directions of smart materials with great potential in recent years. Among them, temperature-regulating clothing constructed by combining special thermally conductive materials to enhance heat conduction efficiency, or by adjusting material microstructure to enhance heat radiation or heat convection, has been proven to have good heat dissipation, cooling or thermal insulat...
