Moisture-conducting heat-dissipating cool-feeling fabric and preparation method thereof

Abstract

The invention provides a moisture-conducting heat-dissipating cool-feeling fabric and a preparation method thereof. A single-layer fabric is adopted, and a three-layer structure with a hydrophilic fabric layer, a high-thermal-conductivity layer and a hydrophobic layer is constructed; the hydrophilic fabric layer is a fabric subjected to hydrophilic modification by adopting polydopamine; the high-thermal-conductivity layer is a high-thermal-conductivity cool-feeling microcapsule coating; and the hydrophobic layer is a coating subjected to single-side hydrophobic finishing. According to the moisture-conducting heat-dissipating cool-feeling fabric and the preparation method thereof provided by the invention, the high-thermal-conductivity coating is adopted to realize a contact cool feeling and a uniform and rapid heat conduction function; a one-way moisture guiding function is achieved by constructing the wetting gradient in the thickness direction, and a skin touch layer is kept dry and comfortable; and meanwhile, polydopamine deposited on the outer layer is on the surface of the fiber, so that the specific surface area of sweat evaporation is increased, heat and humidity are further promoted to be discharged to the external environment, and dry and comfortable experience is brought to a human body.

Description

technical field [0001] The invention belongs to the technical field of functional fabrics, in particular to a moisture-conducting, heat-dissipating, cool-feeling fabric and a preparation method thereof. Background technique [0002] When the human body performs outdoor sports or medical workers stand and work for a long time, it is easy to make the human body wet with sweat. This kind of sweat is concentrated in a large amount and is difficult to discharge quickly. Plaguing people, in order to solve the above problems, people increase the sweat evaporation area by increasing the specific surface area, such as fiber cross-section profiled, hollow or porous fibers to increase water conduction; or hydrophilic modification of the surface of hydrophobic fibers to increase moisture absorption, but The discomfort of the next-to-skin surface caused by its bidirectional moisture transfer and the low water evaporation rate still limit its practical application. Therefore, there is a ...

Problems solved by technology

However, this multi-layer structure undoubtedly increases the thickness of the fabric, which affects ventilation and heat dissipation, and also increases the sense of heaviness, and the heat generated by the human body is easy to accumulate, and it is difficult to quickly excrete the body, and the cooling effect is limited to a certain extent.

[0003] According to the survey, the current cool fabrics have the following disadvantages: 1. Some cool fabrics use multi-layer composite fabrics, which bring a heavy feeling and affect ventilation and heat dissipation; 2. Some cool fabrics use uniform raw materials, and pure hydrophilic fabrics cannot Guaranteed dry and comfortable next to the skin surface when sweating a lot, pure hydrophobic fabrics cannot meet the needs of quickly taking away sweat
