CBRN fabric development for protective clothings

我们需要一种新的屏障技术来防止有害化学物质的侵害，这种技术最终将为消防员、化学工业工人和军人提供更好的舒适度。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。最先进的屏障膜实际上用于制造3级和4级NFPA（国家消防局）服装和CBRN（化学生物放射核）防护服。与这类防护服相关，向内泄漏、液体渗透和化学渗透性能是重要的要求。此外，这种防护服必须防火、防病毒、耐洗。鉴于这种防护服的复杂性和众多/严格的要求，在缓解热应激和改善用户热生理舒适度方面，这一领域的进展缓慢。加拿大的纺织业目前对新工艺、新技术和新材料表现出兴趣，这些新工艺、新技术和新材料将使他们能够生产出更好、更有竞争力的产品，同时降低对环境的影响，提高生产率。投资与技术纺织工业相关的研发项目是很重要的，因为我们可以在未来几年帮助加拿大制造业的扩张，包括技术纺织制造业。

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.
