Abstract

The invention provides a moisture-sensitive self-adaptive breathable fabric. A preparation method of the moisture-sensitive self-adaptive breathable fabric comprises the following steps: preparing a functional material monomer from p-chloromethyl styrene, a polymerization inhibitor and hexafluorophosphate; stirring a functional material monomer, copper chloride, 2, 2 '-dipyridyl and cyclohexanone to obtain a second mixed solution; immersing a fabric base material into the second mixed solution, adding an initiator, taking out the fabric base material after the reaction is completed, and drying to obtain the moisture-sensitive self-adaptive breathable fabric. According to the moisture-sensitive self-adaptive breathable fabric, the functional material is grafted and polymerized on the fabric base material, so that the fabric shows hydrophobicity and maintains the moisture stability of a microenvironment when a human body does not sweat in a large amount, namely the human body does not feel sweating, and when the human body feels sweating in a large amount, the functional material and sodium chloride in sweat are subjected to ion exchange, the material become hydrophilic, moisture is quickly absorbed, moisture discharge is promoted, and the wearing comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a moisture-sensitive self-adaptive breathable fabric. Background technique [0002] The heat and humidity comfort of clothing is an important indicator of clothing comfort. It refers to a performance that the human body will not feel uncomfortable when the human body and the environment continue to exchange heat and moisture and gradually reach a balance in different climates after wearing the clothing. [0003] The real demand of the wearer for clothing is that when the human body is in a high-temperature, high-humidity environment or undergoes a lot of exercise, the sweat can quickly pass through the "wet transfer" process of the textile fabric, and the heat and water vapor on the body surface will be exported out of the outerwear to reach the body surface and clothing. In between dry and comfortable state, but in other states will not make the skin too dry. At pr...
