Thermo-regulated textiles is a by low-temperature phase change material bonded to the textile surface or implanted inside the fiber, textile when the ambient temperature change, it can automatically absorb, storage, redistribution and release heat when when the ambient temperature is below the set value, the occurrence of liquid - solid phase transition emit heat, to maintain a high temperature so that the textile internal; absorbs heat solid - liquid phase transition occurs when the ambient temperature is higher than the set value, so that the textile is kept internally lower the temperature to a temperature in a comfortable range. Thermo-regulated textiles is an intelligent textiles, comfort is the most important in the twenty years since the self-waterproof and breathable fabric textile technology. The purpose of this study is developed with near-infrared and visible light absorption at room temperature, and can absorb and emit heat fiber - light-heat conversion thermo-regulated fibers applied basic research. Study infrared light, photographic light, silicon carbide external voltage regulator, infrared thermometer, point Wenyi zirconium carbide, silicon carbide and aluminum oxide, near-infrared, visible light absorption properties on the basis of the 0 - 8% of the zirconium carbide and 4% of the silicon carbide powder is added to the polypropylene melt (composite) spinning, made from fibers of a variety of compositions and structures, and using DSC, TG, infrared thermometer, point temperature meter and strength tester, fiber light and heat absorption properties, thermal stability and mechanical properties were studied systematically. In this study the low temperature phase change material - paraffin as core, urea - melamine - formaldehyde copolymer wall, using the in situ polymerization of the phase change material microcapsules of less than 10 microns in diameter, and using DSC, TG, SEM and LM means of the structure, properties and influencing factors of the microcapsules were studied systematically. The study will also phase change material microcapsules and light-heat conversion ceramic powder plus ingredients, functional fill polypropylene substrate, melting (composite) spinning, spinning out of the light-heat conversion thermo-regulated fiber DSC, TG, SEM, LM, infrared thermometer, point thermometer and powerful instrument, such as a variety of instruments and methods to study the relationship between the manufacturing process and the fiber structure and performance, build applications for the production of fiber development theory foundation. 1, the different wavelengths of infrared rays on the endothermic properties of the ceramic powder has a significant effect, the absorption wavelength of the type of the type of ceramic powder, zirconium carbide, silicon carbide having better than the aluminum oxide by this study, the following conclusions: Infrared absorption performance. 2, plus the amount of ceramic powder filling affect the performance of the photothermal conversion fiber nonwoven fabric, fiber non-woven fabric photothermal conversion capacity increases with increasing the amount of fill added; but the amount of fill added after 4% of the photothermal conversion capability will no longer increase and continue to increase the amount of fill added, the nonwoven fabric surface temperature but declined. 3, the photothermal conversion fiber non-woven fabric and polypropylene fiber non-woven fabric as compared to having a good heat storage performance and insulation performance of up to 7.4 ° C, the maximum temperature difference between the minimum temperature difference of 1.6 ° C. But experiments confirmed that the the photothermal conversion fiber has strong light absorption in the near-infrared and visible wavelengths, easy photothermal conversion occurs. 4, the test results indicate that the type of structure of the photothermal conversion fiber woven fabric, in order to effectively use the photothermal conversion ceramic powder, zirconium carbide powder wood should be placed in the fiber cortex. 5, urea - melamine - formaldehyde as wall material of the microcapsules can be well coated with paraffin hydrocarbons and the formation of the microcapsules, the microcapsules prepared with excellent performance, uniform size, and realize the miniaturization of the (particle size <10 microns) . 6, one of the in situ polymerization is the preferred method of preparing microcapsules, the microcapsules prepared in the active ingredient paraffin content of up to about 57 ~ 69%, the microcapsules had an average particle diameter of 3.3 microns, the microcapsules the heat storage within the range of 140 ~ 170J / g. 7, heat-resistant temperature of the phase change material microcapsules is less than 160 ac to really meet the technology needs of the melt spinning, further improve the heat temperature. 8, containing 4% polypropylene wrong carbide as a skin material, polyethylene containing 0-20% of the phase change material of the microcapsules and developed a thermo-regulated fiber core layer by melt composite spinning method, the phase change material microcapsule accounted for 12% of the total fiber weight, nearly 50% of the United States similar developed more than four times the fiber, Acrylic fiber than the current size of the already high levels of microcapsules. 9, the fineness of the fiber HT3 regenerative thermostat 5.43dtex, rupture strength 2.19oN/dtex, elongation at break of 31.9%; WT the composite fiber fineness sdtex, rupture strength 2.236oN/dtex, fracture elongation 38.5 %. 10, the reference to the fiber sample HTI, the sample HT and WT have the obvious effect of the heat accumulator and thermostat, wherein the sample HT lifting range of temperature within 2 a stone ... 6.5 ° C. 11 in the near-infrared irradiation, the heating rate of the sample HT significantly faster than the rate of temperature rise of the sample WT and pure polypropylene fabric thermostat and has good insulation effect, that the sample HT is not only light-heat conversion function, and also has good temperature regulation.
