The needs for better thermal protection exist in various fields of our life, like the better thermal treatment, outside chill sports field and
freezing working condition etc. However, the traditional passive thermal insulated clothing is insufficient, too blocky and heavy to constrain
the movement of wearers and uncomforted to wear. Thus, an innovative light, flexible and active wearable thermal protection needs to be
developed. This article reviews the relevant wearable thermal textile technology by utilizing the latest conductive textile materials in three
developing levels: the fiber level, the yarn level and the fabric level, to provide more possibilities for new products development in various
fields, which will facilitate the transfer from research achievement into mass production to realize its commercial benefits.
