Abstract
A cellulosic fiber includes a fiber body including a cellulosic material and non-encapsulated phase change material dispersed within the cellulosic material. The non-encapsulated phase change material forms a plurality of distinct domains dispersed within the cellulosic material. The non-encapsulated phase change material has a latent heat of at least 40 Joules per gram and the cellulosic fiber has a latent heat between 9.8 Joules per gram and 132 Joules per gram and a transition temperature in the range of 0° C. to 100° C., and cellulosic fiber provides thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature.
