CBRN fabric development for protective clothings

需要新的屏障技术--防止有害化学物质--最终为消防员、化工工人和军事人员提供更好的舒适性。例如，这种化学防护服可用于个人防护、外套、北极军事任务和科学防护服。*最先进的阻隔膜实际上用于制造用于CBRN(化学生物放射性核)防护的3类和4类NFPA(国家消防局)套装和服装。与此类型的防护服相关的，向内渗漏、液体渗透和化学渗透性是重要的要求。此外，这种防护服必须防火、防病毒和耐洗。*鉴于这种防护服的复杂性和众多/严格的要求，这一领域在缓解热压力和改善用户的热生理舒适性方面进展缓慢。*加拿大的纺织业目前对新工艺、技术和材料表现出兴趣，这些新工艺、技术和材料将使他们能够制造更好、更具竞争力的产品，环境影响更低，生产率更高。重要的是投资于与工业纺织行业相关的研发项目，因为我们可以在未来几年帮助加拿大制造业的扩张，包括工业纺织品制造。**

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 Class 3 and Class 4 NFPA (National Fire Protection Agency) 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. In addition, such protective clothing must be fire resistant, virus resistant and wash resistant. ****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.****The textile industry in Canada is currently showing interest in new processes, technologies and materials that would allow them to manufacture better, more competitive products with lower environmental impact and improved productivity. It is important to invest in R&D projects related to the technical textile industry because we could assist in the expansion of the canadian manufacturing sector, including technical textile manufacturing, in the coming years.**
