About Company:

CTT Group is a technology transfer center specialized in the research, development and testing of technical textiles, advanced textile-based materials and geosynthetics. We are committed to advancing technological innovation and assisting industry in the conception, production and marketing of value-added products.

Summary of Project:

There is a need for novel barrier technologies -to protect against harmful chemicals- that will eventually provide better comfort for firefighters, chemical industry workers and military staff. Such chemical protective clothings could be used, for example, in personal protection, outerwear, arctic military missions and scientific protective clothing.

State of the art barrier membranes are actually used in the manufacturing of Ensembles and clothings for CBRN (Chemical Biological Radiological Nuclear) protection. Related to this type of protective clothings, inward leakage, liquid penetration and chemical permeation properties are important requirements. Given the complexity of such protective clothings and numerous/stringent requirements, progress in this area has been slow regarding relief of heat stress and improvement of thermo-physiological comfort for the users.

Research Objectives/Sub-Objectives:

The general objective is to develop barrier membranes used in the manufacturing of Class 3 and Class 4 NFPA (National Fire Protection Agency) Ensembles and clothings for CBRN (Chemical Biological Radiological Nuclear) protection.

Specific objectives are to meet requirements as listed in NFPA 1994: 2013 and 2018 editions:

  • Inward leakage protection and pass the shower test (seams included)
  • Liquid penetration protection
  • Chemical permeation protection 


    • New materials will be developed, studied and implemented in protective clothing prototypes

    Expertise and Skills Needed:

    Knowledge in at least one of these areas: chemical adsorbents, decontamination chemistry, polymers, surface treatments, textile finishing
