IIT-Delhi develops PPE with adequate level of breathability – Times of India


NEW DELHI: The Indian Institute of Technology Delhi (IIT-D) has developed an affordable personal protective equipment (PPE) that reaches adequate levels of breathability. This PPE according to researchers also has anti-bacterial property, not available in other similar products.

S.M. Ishtiaque, Professor Emeritus, department of Textile and Fibre Engineering, IIT Delhi and his student, Biswa Ranjan Das, scientist at DRDO, Kanpur, has developed this advanced version of PPE.

“The advanced version of PPE coverall that we have developed is set to emerge as an improvised product in the national and international markets, bestowing several special functional features, to meet requirements for added comfort. Breathability and feel of the coverall has been a major challenge and we have ensured we reach adequate levels of breathability and a softer feel, to support extended wearability,” said Ishtiaque.

The salient features of this PPE is special coating and treatment formulation, applied over very light and compact polyester woven fabric.

“This has permitted the PPE weight maintenance to 300 gm against commercially available 400-500 gm. It has an excellent antibacterial property and such feature is not available in most of the commercially available PPE coveralls. There is special grade PU coating, providing very smooth surface feel and adequate clothing breathability, which provide comfort to users,” added Ishtiaque.

The PPE can be reused three times which has led to reduced cost. It is available in four body sizes and shoe cover , which can fit a complete range of users, as opposed to universal/ limited size in commercially available coverall. The researchers have collaborated with G. D. International to produce 1,20,000 coveralls/ month.
