摘要
将含有固-液相变材料的调温微胶囊结合水性聚氨酯黏合剂,通过浸轧的后整理方式处理到纯棉织物上,使织物具备一定的调温效果。探讨了调温整理液中调温微胶囊含量占比对织物增重、调温性能、透气性能以及透湿性能的影响。结果表明:经过调温整理后的织物焓值与整理液中调温微胶囊的含量有关,调温微胶囊含量越高,织物焓值越大;将升、降温阶段的实际焓值与理论焓值进行Pearson相关性分析,两者之间呈现较高程度的正相关关系。通过调温整理后织物的升温实验可知,整理液中调温微胶囊含量越高,织物升温速率越慢。在黏合剂浓度一定的条件下,调温微胶囊含量越高,织物增重越明显,织物透气性越差。与原织物比较,经过调温整理后的织物透湿性能下降,但是,比较经过不同调温微胶囊含量整理的织物,浸轧液中调温微胶囊含量越高,织物的透湿性能反而越好。
Pure cotton fabric is treated by means of padding with polyurethane （ PU ） adhesive containing solid-liquid phase change material to make it thermal regulating. The effect of the amount of microcapsules in the concentration on weight gain, thermostat performance, air permeability and water vapor permeability has been investigated. The result indicates that the enthalpy of fabric incorporated with MPCMs shows higher as concentration of microcapsules increased. The actual enthalpy of treated fabric has a better correlation with the theoretical enthalpy. The heating rate of the fabric shows slow as the microcapsule phase change material increased. The weight gain of fabric incorporated with microcapsules increases depending on the amount of microcapsules added to the fabric. The air permeahility is decreased as the concentration of microcapsules increased. Compared to the fabric before finished, the water vapor permeability of the fabric finished is reduced, however the water vapor permeability of the finished fabric increases with more microcapsules treated.
