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.

In house extraction of floral base Nano Particle (Al-NPS) was applied on cotton fabric by using padding technique. Zone of inhibition was used to identify the antibacterial property. In this present study, an endeavor was made to finish cotton textiles with herbal based aluminum nanoparticles with different ratios to impart the antimicrobial finishes. Aluminum Nanoparticle synthesized with plant source as core material and variation of concentration of leaf extracts with reducing agents has produced different ratios. The Al-Nps treatment with different percentage (4% & 5%) of herbal (Neem & Guava) base precursor was with different ratio 1:1, 2:1, 5:1 & 10:1 amplifying the antimicrobial & antifungal properties of the treated fabric. Pad dry curing was carried at 140°C for 3 mins. After that evaluated the antibacterial property, wash fastness property, geometrical parameters of the specimen with treated nanoparticles and untreated fabric by using qualitative method AATCC-147, 2004 for the growth of inhibition and AATCC-30, 2004 for antifungal activity. Antibacterial action was found to zero in knitted untreated fabric.
