There is also an increased demand for more accurate and sophisticated experimental as well as theoretical approaches in order to accomplish a balance between them and also to enable the textile engineer to achieve more meaningful and reliable system designs.
Also, impregnation with silica aerogel has been reported to lead to lower thermal conductivity in the case of fibrous ceramics.
