4. Conclusion
The chemical protective clothing has been designed and developed to suit the requirements of chemical protection along with comfort. The maximum penetration was in case of acetone and it was 0.4 %, while the no penetration in case of hydrogen peroxide and sodium hydroxide. The maximum permeation was in case of dichloromethane and it was 10.79%, while no permeation in case of sulphuric acid. The maximum degradation was in case of sulphuric acid and the weight loss of the fabric was 18.60%, while no degradation in case of sodium hydroxide, Hydrochloric acid and Dimethyl Formamide. Some of the chemicals were retained by the fabric. The chemical resistance of the fabric has a good resistance towards most of the liquid chemicals and some of the chemicals in vapor form. Thus the developed chemical protective clothing is breathable along with non permeablibility.
5. Future Scope
The fabric was formed using activated carbon granules, fabric can be made of advanced materials such as activated carbon fibres. It can be made using selectively permeable membranes. The toxicity of vapors passing through the fabric can be analyzed using toxic vapor analyzer. The other non woven production technologies can be tried for coating of activated carbon. The bonding of different layers of fabric can be tried with other kinds of resins that provide more flexibility.
