通过研究微胶囊相变粘胶纤维(MPCM-R纤维)及其混纺织物的应用性能,为智能调温纺织品的开发提供技术支撑。检测MPCM-R纤维及其混纺织物的温控性能、保暖性、安全性、耐久性与力学性能发现,MPCM-R纤维的熔融峰温为28.03℃,结晶峰温为10.82℃,熔融焓值和结晶焓值分别为5.489J/g和5.537J/g,30次洗涤后焓值仍大于5J/g,且相变材料的引入对纤维的干、湿断裂强力影响较小,无皮肤刺激性和经口毒性。此外,此MPCM-R纤维与棉纤维的混纺织物在环境温度急剧变化的情况下表现出较好的温控能力,可以延缓织物本身的温度变化,且具备良好的耐洗涤和保暖性。
To provide the technical support for the development of intelligently temperature-regulating textile,studying the application properties of microencapsulated phase-change viscose fiber and its blend fabric was focused on.The temperature-regulating effect,warm-keeping property,safety,durability and tensile strength of the fiber and its blend fabric were measured.The melting peak temperature and crystallization peak temperature of the fiber were 28.03℃ and 10.82℃.The melting enthalpy and crystallization enthalpy were 5.489J/g and 5.537J/g,and the enthalpies of the fiber after 30 washing cycles was still greater than 5J/g.Introducing the microencapsulated phase-change material had little effect on the tensile strength of the fiber without toxic and skin irritation.Further,the blend fabric of the fiber and cotton fiber presented good temperature-regulating effect and temperature variation was delayed when the surrounding temperature had rapid change.And the blend fabric also presented satisfactory washing durability and warm-keeping performance.
