发热蓄热保暖舒适性纺织品的制备与性能研究

Study on the Preparation and Performance of Heat-storing Textiles

吸湿发热材料和相变微胶囊是当今发热蓄热调温纺织品研究的重要方向,将相变微胶囊涂覆到吸湿发热面料上制得调温复合面料,对其调温性能(热学性能、吸湿发热性能、升降温性能、带液率、表面形态)和服用性能(透气性、耐水洗性)做了测试研究。结果表明:随着微胶囊浓度和交联剂浓度的增加,复合面料的调温性能逐渐增强,服用性能略微下降,推测其机理可能为相变微胶囊吸收吸湿发热面料产生的热量达到调温效果。

Moisture absorbing and heat-generating materials and phase-change microcapsules are important research directions of temperature regulating textiles.Phase-change microcapsules were coated on the moisture absorbing and heat-generating fabric to produce the temperature-regulating composite fabrics.The temperature-regulating performance(thermal properties,moisture absorption and heat-generating properties,temperature rising and falling,liquid carrying ratio and surface morphology)and wearing performance(air permeability and washing durability)were tested and studied.The results showed that with the increase of microcapsule concentration and crosslinker concentration,the temperature regulating performance of the composite fabric gradually increased but the wearing performance decreased slightly.It was speculated that the mechanism might be that the phase-change microcapsules could absorb the heat generated by the moisture absorbing and heat-generating fabric to achieve the temperature regulation.
