Abstract

The research evaluates change in heat transfer and relative humidity in a spring type of shape memory alloy (SMA) attached fabrics. Since newly developed SMA is sensitive to temperature, and expands rather quickly when exposed to the low temperature, the SMA can be used to adjust the microclimate volume between layers in a multilayered garment system. Three types of polyester knit fabrics were embedded with SMA springs and microclimate was measured by Human-Clothing-Environment (HCE) simulator. The data shows that microclimate temperature, formed by SMA springs between the fabrics, is obviously different from that of the multilayered system without SMA springs.
