Abstract:

In order to study the cotton / mercerized wool / Outlast fiber blended yarns’ thermal properties, DSC was used to test the thermal properties of the blended yarn by varying Outlast fiber content. The results showed that the ffect of Outlast fiber content on the beginning, ending, and peak temperatures of the phase-changing temperature-regulating of is very small, only in the cooling process the ending and peak temperatures slightly decrease with the Outlast fiber content increases. Furthermore, there is a linear relationship between the yarns’ enthalpy values and the Outlast fiber content at the time of cooling, but it is not so prominent during the warming process. When Outlast fiber content is 40%, yarn’s enthalpy value and the starting and ending points of phase-changing are better.
