Embodiment 1

[0028] Release 8kg of polyurethane-wrapped heat-sensitive material microcapsules of n-eicosane as the heat-sensitive phase change material, 4kg of polyacrylate, and 3kg of softener in the chemical tank to 100L, stir them evenly, and put them into the rolling groove of the setting machine Inside, the pre-treated cloth is dipped through the rolling groove, and the pressure of the roll is 2.5kg / cm 2 , and then baked in a drying room at 110°C for 45 seconds, and then subjected to post-shrinkage treatment to obtain a phase-change polyurethane heat-sensitive material microcapsule two-way temperature-regulating fabric with a phase change temperature of 36.4°C.

Embodiment 2

[0030] The heat-sensitive phase-change material in embodiment 1 is changed to the mixture of n-octadecane 33% (weight percent), n-docosane 67% (weight percent), and all the other ways are unchanged, so that the phase transition temperature is 37.8 ℃ phase-change polyurethane heat-sensitive material microcapsule two-way temperature-regulating fabric.

Embodiment 3

[0032] The heat-sensitive phase-change material in embodiment 1 is changed to the mixture of n-hexadecane 25% (weight percent), n-docosane 75% (weight percent), and all the other ways are unchanged, so that the phase transition temperature is 37 ℃ phase-change polyurethane heat-sensitive material microcapsule two-way temperature-regulating fabric.

Abstract

The phase change polyurethane heat sensitive microcapsule dual thermoregulation material starts with making microcapsules in wrapping heat sensitive material with polyurethane, then sticks the microcapsule to the fiber surface of fabrics, with the heat sensitive materials being mixed by one or more of the tetradecane, octacontane, arachidonic acid, and docosane. It can control body temperature within certain range through dual thermal control. It can be used in the production of any kind of fiber dual thermal control material with less difficulty for manufacturing.

Description

technical field [0001] The invention relates to a fabric, in particular to a preparation method of a two-way temperature-regulating fabric made of microcapsules of phase-change polyurethane heat-sensitive material. It belongs to the field of textile technology. Background technique [0002] There are many varieties of apparel fabrics in the market. According to people's demand for clothing in different seasons, there are cool types and warm types. However, traditional clothing fabrics are nothing more than controlling the conduction, convection and radiation of heat to achieve the purpose of keeping people warm. In recent years, with the improvement of people's living standards, people's demand for clothing fabrics has also undergone great changes, and some "functional" fabrics, "comfortable" fabrics and "smart" fabrics have been developed one after another. "Smart" textiles use heat-sensitive materials wrapped in microcapsules to adjust the temperature of the human body ...
