In recent years, as a sway of high pace development in science and technology, people tend to have more aptitude towards using clothing for new functions, which ultimately contributes to opening of opportunities for further development and incorporation of new technologies along with novel materials. In this context, textiles are of fast decalescence or fast heat radiation media as far as comfort accountability of textile articles is concerned. The structure and texture of textiles play a very vital role in determining the thermal comfort level of the human body; hence, people need to obtain various advantages of the functional material design in order to improve the heat–moisture balance of textiles. Thermal comfort depends on the extent to which the clothing influences heat and moisture transport between the human body and environment. In order to come up with solution for this, the use of silica aerogels gains extreme attention due to their surprising properties and their existing potential applications in a wide of variety technological areas. Aerogel basically exhibits nanostructure which offers high porosity, high specific surface area, low density and outstanding heat insulation properties. This paper emphasis on development of thermal insulative PET nonwoven fabric with the application of silica aerogel which gives excellent thermal insulation with reduced bulk and weight which are generally enforced to insulative textile materials to induce functionality. Findings are supported by various analyses and testings followed by STATISTICA 6 software for ensuring statistical significance of all parameters. The developed product shows the potential to be used at various technical textile product ranges.
