含大量相变物质的调温纺织纤维

将相变物质（PCM）结合到纺织纤维内是获得调温性能的一种方法。在体温升高时，PCM熔化，以潜热的形式从人体吸收热量（冷却效应）；温度降低时，PCM结晶，再释放储存的热量（加热效应）。通过熔纺皮芯结构的双组分纤维，将PCM结合进纺织纤维并将其封闭在纤维内，便可成功生产出以PA6和PET为皮层的双组分纤维。PCM最高含40...

Temperature regulating textile fibers containing large amounts of phase change material

Integration of phase change materials （ PCM＇ s） in textile fibers is a means to achieve thermo-regulating properties. When the body temperature goes up, the PCM melts and absorbs the heat from the body in the form of latent heat （cooling effect）. When the temperature drops, the PCM crystallizes and the stored heat is released again （warming effect）. PCM＇s can be integrated into textile fibers by means of melt spun bi- component fibers with a sheath/core structure. In this way PCM is trapped inside the fibers. Bi-component fibers with PA 6 and PET sheaths were in this way successfully produced. Fibers containing up to about 40% PCM were produced showing heat of fusions up to about 80 J/g and tenacities above 15 cN/tex. The loss of PCM during use and repeated washing cycles was shown to be low.
