Research progress in preparation technologies of phase-change temperature-regulating fibers
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.
