This research study reports on thermal insulation properties of six samples made from recycled Cotton/Polyester selvedge waste for automotive interior applications. The selvedge waste recycled from cotton/ polyester fibers have a possible source of raw material that can be measured for thermal insulation purposes, but its amounts are limited. In the procedure of different-layer nonwoven sheets are prepared with a chemical bonding method. The entire samples were tested for thermal insulation according to their physical properties as per the ASTM and ISO standard. The thermal insulation properties were measured according to thermal conductive in solids Principle method, thermal insulation values on over six temperatures 0,50,100,150 and 200 (TIV) were calculated. The results showed that the nonwovens were made from recycled Cotton/ polyester selvedge wastes have confirmed more than 75% of the thermal insulation application. The recycled waste cotton/ polyester selvedge nonwoven mats have satisfactory moisture resistance at high humidity situations without disturbing the insulation properties. From this research it is concluded that the nonwovens produced from 100% polyester and 50/50 C/P nonwovens shows that better thermal insulation performance.
