相变调温纺织品制备方法的研究进展

为明晰制备工艺对调温纺织品性能的影响,综述了相变调温纺织品的2种制备方法:即在中空纤维中填充相变材料或将相变材料加入纺丝液制备相变纤维,再经织造形成相变织物;或者通过直接填充、表面整理、表面接枝改性等直接复合方式获得相变织物.分析认为:中空纤维填充法对选用的纤维材料要求较高;直接填充法工艺简单、操作方便,但会使纺织品舒...

Recent advance in preparation of thermo-regulating textiles based on phase change materials

In order to clarify the effect of preparation process on the properties of temperature adjusted textiles,the paper reviewed recent reports dealing with preparation of thermo-regulating textiles using phase change materials(PCMs).Two strategies could be used to incorporate PCMs:they could be introduced either to filling hollow filaments or after the spinning stage,or to fabrics by direct filling,surface grafting,or coating of phase change microcapsules.Fabrication of phase-changing yarns via filling hollow filaments with PCMs is applicable only to a limited amount of fiber materials.Direct filling of woven fabrics is simple and convenient,yet at the cost of handle and comfortableness of the finished fabric.Spinning of or finishing with PCM microcapsules have been industrialized.However,the amount of PCMs incorporated tends to be low.The electrospinning method is not easy to be industrialized.The surface grafting method yielded textiles with good and durable temperature regulating properties,yet suffered from complicated processing.Finally,the future development of temperature regulating textiles with phase change materials is prospected.
