India is making progress in the development of indigenous protective clothing designed to improve safety and comfort in extreme heat conditions. Research at the Indian Institute of Technology (IIT) Delhi, supported by the Defence Research and Development Organisation (DRDO) through its research collaboration, highlights the country’s growing capabilities in advanced technical textiles and protective equipment.
According to IIT Delhi’s Department of Textile and Fibre Engineering, a lightweight heat-protective jacket weighing approximately 2.2 kg has been developed under the SITEX 05 project. The project focuses on protective clothing for defence personnel who operate in high-temperature environments. The jacket features a four-layer construction designed to provide thermal insulation, flame resistance and wearer comfort.
Its outer shell uses aramid woven fabric, known for its flame-retardant and heat-resistant properties. The other layers include a moisture barrier, thermal liner and inner face fabric. Together, these components are designed to protect personnel against heat exposure while maintaining comfort during demanding operations. IIT Delhi reports that the jacket achieved a Thermal Protective Performance (TPP) rating of 38 under the specified NFPA testing conditions.
Separately, DRDO’s Centre for Fire, Explosive and Environment Safety (CFEES) has developed a lightweight structural firefighting suit. According to DRDO’s published technology-transfer document, the complete suit, including its coat and trousers, weighs less than 2.8 kg. It provides a Thermal Protective Performance rating exceeding 44 under NFPA 1971 requirements.
The DRDO-developed firefighting ensemble incorporates three protective layers: an outer shell, a moisture barrier and a thermal barrier. The outer layer protects against flames, heat, water, chemicals and physical damage, while the inner layers help reduce heat transfer and improve moisture management and wearer comfort.
These developments address an important requirement in protective equipment: providing reliable thermal protection without placing unnecessary physical strain on personnel. Heavy protective clothing can restrict movement and increase fatigue, particularly during prolonged operations in challenging environments.
Indigenous development of advanced protective textiles also offers opportunities to strengthen domestic manufacturing capabilities and reduce dependence on imported specialist materials. The research conducted by IIT Delhi and DRDO demonstrates India’s continuing efforts to develop homegrown solutions for defence and emergency-response requirements.
Although the two developments involve different protective applications, both reflect the importance of lightweight, high-performance materials in improving personnel safety. Further industrial adoption and technology development could help expand the availability of domestically developed protective clothing in India.
