The phase change fiber is a heat accumulating and temperature regulating functional fiber developed by utilizing the characteristic of releasing or absorbing latent heat and keeping the temperature unchanged in the phase change process of a substance. The phase change is mainly represented by the transformation between liquid and solid, or the change of crystal-crystal, crystal-liquid and its molecular aggregation structure phase in the solid, and the temperature is kept by the absorption and release energy of the transformation. The phase-change fiber can freely adjust the internal temperature of the textile in a certain temperature range according to the change of the external environment temperature, can store energy when the external environment temperature is increased, and releases energy when the external environment temperature is reduced, so that the internal temperature of the textile has relatively less fluctuation, and people feel more comfortable when wearing and using the textile. Phase change fiber fabrics differ from traditional fiber fabrics in the thermal insulation mechanism. The traditional heat-insulating clothes mainly avoid excessive skin temperature reduction by a heat insulation method, and the heat-insulating mechanism of the phase-change fiber is insensitive to deformation, moisture and air pressure, has no overstrain and heavy feeling, and can provide a comfortable microclimate environment for a human body. The reason for this is that the phase change material provides thermal conditioning rather than thermal isolation. The thermal insulation mechanism is realized by the phase change material in the textile, namely the phase change material absorbs or releases energy when changing between solid-liquid phase state and liquid-liquid phase state. In the textile field, the function of regulating the temperature can be achieved by using phase change materials contained on the textile surface or in the fibers. The material can freely adjust the temperature of the textile in a certain temperature range according to the change of the external environment, and has more comfort than the common conventional textile.
The following table is a graph of the performance parameters of the material for the bedding and clothing made in accordance with example 2 of the present invention tested according to GB/T11048 by Zhejiang certain inspection company compared to the performance parameters of an energy quilt tested by Shandong certain group company.
Conclusion of experiment:
according to the third party detection report data, the thermal insulation performance and compression retraction elastic performance of the invention are better than those of similar products in the market. The wet resistance (air permeability) of the invention is better under the same gram weight of the flocculus. Under the condition of introducing aerogel fibers, antibacterial and anti-mite fibers, anion fibers and low-melting-point fibers, the invention improves the warmth retention property, health care, antibacterial and anti-mite functions, and simultaneously does not reduce the air permeability.
Remarks: the thermal resistance, the Crohn value and the heat preservation rate are indexes of the heat preservation performance of the quilt, and the higher the value is, the better the heat preservation performance is; the compression rate and the recovery rate are indexes of compression rebound resilience performance of the quilt, and the higher the value is, the better the fluffiness and rebound resilience performance of the quilt are.
