摘要
介绍了相变材料的分类及各自的性能特点,综述了目前相变微胶囊及相变调温纤维的制备方法,并指出了不同制备方法存在的优缺点及应用范围.目前,适用于纺织领域的相变材料主要为有机相变材料石蜡;相变微胶囊的制备主要采用化学法,该方法在纺织领域应用较多,关键技术是乳化工艺;相变调温纤维的制备多采用复合纺丝法和后整理法,但存在相变微胶囊的制备工艺较复杂、加入相变材料损伤纤维机械性能、相变调温纤维经过纺纱及织造等流程后调温能力减弱等问题.指出相变微胶囊的制备技术、相变调温纤维的制备工艺、相变材料的保持率及温度调节能力的稳定性等是相变调温纤维未来发展的重点研究方向.
Abstract
The types and performance characteristics of phase-change materials were introduced.The preparation technologies of phase-change microcapsules and phase-change temperature-regulating fibers were reviewed.The advantages,disadvantages and application of different preparation methods were described.The phase-change material suitable for the textile field is mainly or-ganic phase change material paraffin wax.The preparation of phase-change microcapsule dominantly adopts chemical method which is widely used in the textile field and the key technology is emulsification process.The preparation method of phase-change temperature-regulating fiber mostly adopts composite spinning method and finishing method,which has the main problems such as the complex preparation process of phase-change microcapsule,the damage to the mechanical properties of the fiber resulting from the addition of phase-change material,and the declination of temperature-regulating ability of phase-change temperature-regula-ting fiber after spinning,weaving and other processes.It was pointed out that the key development directions of phase-change temperature-regulating fibers should be focused on the preparation technology of phase-change microcapsules,the preparation process of phase-change temperature-regulating fibers,the retention rate of phase-change materials and the stability of tempera-ture-regulating ability.
