摘要

Spherical microcapsules with a 49 wt % of Rubitherm ~? RT31 were successfully synthesized by means of suspension-like polymerization to be used for textile applications in summer conditions. Microcapsules were fixed into seven fabric substrates for different textile applications by a coating technique without deteriorating original functionalities of the textiles. Thermal performance of different coated textiles with 35 wt % of microcapsules was evaluated by differential scanning calorimetry (DSC) and infrared thermography (IR) techniques and the physical characteristics of textiles with thermo-regulating properties were examined by environmental scanning electron microscopy (ESEM). It was observed that all treated textile substrates allow to obtain thermo-regulating properties with acceptable latent heat storage capacities. Results also indicated that the presence of microcapsules containing Rubitherm ~? RT31 produces a significant thermal insulation effect during a cold to warm transition (20-45°C). Thus, this kind of microcapsules can be used to obtain textiles with thermal comfort-related properties.

RT31是通过悬浮样聚合成功合成的,可用于夏季条件下的纺织品应用。通过涂覆技术将微囊固定到用于不同纺织品应用的七个织物基质中,而不会降低纺织品的原始功能。通过差示扫描量热法(DSC)和红外热成像(IR)技术评估具有35 wt%微胶囊的不同涂层纺织品的热性能,并通过环境扫描电子显微镜(ESEM)检查具有调温性能的纺织品的物理特性。观察到,所有处理过的纺织品基材都可以以可接受的潜热存储能力获得调温性能。结果还表明,存在含有茜草素微胶囊的微胶囊。在从冷到热的过渡过程中(20-45°C),RT31产生显着的隔热效果。因此,这种微胶囊可用于获得具有与热舒适性有关的性质的纺织品。
