Description

technical field [0001] The invention relates to a segmented-pie-shaped temperature-regulating energy-storage fiber, which belongs to the technical field of functional materials, in particular to a segmented-pie-shaped temperature-regulating energy-storing phase-change fiber and a preparation method thereof. Background technique [0002] Phase change fiber is a kind of heat storage and temperature regulating functional fiber developed by utilizing the characteristics of releasing or absorbing latent heat and keeping temperature unchanged during the phase change of matter. In the process of phase transition, substances absorb and release energy to form their own microclimate. In this microclimate environment, the temperature is relatively constant and the external environment changes have little effect on it. Deeply affected by the energy crisis, reducing energy consumption and saving energy has become an urgent problem to be solved. The research on phase change fibers with te...

[0003] Conventional phase change fibers usually have shortcomings such as slow heat transfer and slow temperature adjustment rate. In order to improve similar problems, a Chinese invention patent application (application publication number: CN106801266A, application publication date: 2017-06-06) discloses phase change energy storage fibers The phase change energy storage fiber has a skin-core structure, the skin-core structure includes a skin layer and a core layer, the raw material of the skin layer is thermoplastic polymer, and the raw material of the core layer is a mixture of thermoplastic polymer, clay mineral powder and phase change material

The phase change energy storage fiber is a composite phase change material prepared by phase change material, clay mineral powder and thermoplastic polymer uniformly prepared to obtain a core layer raw material, and the core layer raw material is then compounded with a skin layer made of thermoplastic polymer The spinning machine is melt spun and spun into a phase change energy storage fiber with a skin-core structure. The phase change energy storage fiber with a skin-core structure of the present invention can prevent the leakage of the phase change material and improve the temperature adjustment rate to a certain extent. The disadvantages It is the sensitivity to temperature that needs to be further improved
