Development of a perfluoro-compound-free durable water- and oil-repellent finish for textiles******

目前所有的防水夹克都是用一种被称为持久拒水剂（DWR）处理的。如今的dwr可分为两类：一类是含有全氟碳化合物（pfc）的dwr，另一类是不能驱油的dwr。第一类是有问题的，因为PFCs对人类有毒，暴露会导致出生体重降低、妊娠并发症和儿童免疫功能低下。加拿大已经认识到这一点，并将在2023年之前逐步淘汰全氟化碳。然而，今天只有含pfc的dwr表现出拒油性。这就是为什么存在第二类DWR的原因：一些服装制造商为了提高环境和人体健康而放弃了他们服装的防油性能。不幸的是，防油对于防止汗水进入服装纤维至关重要。没有防油，夹克很容易弄脏，然后失去防水性能。总部位于温哥华的运动服装制造商Arc’teryx认识到这个问题的内在困难：他们的产品既需要防油性，又需要环境可持续性，而目前市场上还没有解决方案。****这个项目的目的是开发一种非pfc的耐油DWR。戈洛文博士在UBC的研究小组与Arc'teryx合作进行这项努力，以开发第一种不含pfc的防油纺织品整理剂。戈洛文的研究小组最近发现，即使典型的有机硅材料完全被油弄湿，纳米有机硅也能排斥油。该项目将探索纳米有机硅如何驱油，如何将这些纳米有机硅应用于纺织品，以及如何使这种新的纺织品整理剂足够耐用，以满足Arc'teryx的性能需求。在这个为期36个月的项目结束时，预计一种基于纳米硅酮技术的无pfc纺织品整理剂将准备好在Arc'teryx的所有纺织厂大规模生产和应用。******

All current waterproof jackets are treated with what is known as a Durable Water Repellent (DWR). DWRs today can be grouped into two categories: those containing perfluorocarbons (PFCs), and those that cannot repel oil. The first category is problematic because PFCs are toxic to humans, with exposure causing lowered birth weight, pregnancy complications, and immunocompromised children. Canada has recognized this, and PFCs will be completed phased out by 2023. However, today only PFC-containing DWRs exhibit oil repellency. That's why the second category of DWR exists: some apparel manufacturers have traded their clothing's oil-repellent properties for increased environmental and human health. Unfortunately, oil repellency is vital to keep sweat out of the fibres of apparel. Without oil repellency, jackets are easily soiled and then loose their waterproof properties. Arc'teryx, the Vancouver-based sportswear apparel manufacturer, recognizes the inherent difficulty in this problem: their products requite both oil repellency and environmental sustainability, for which today there is no solution on the market.****The purpose of this project is to develop a non-PFC DWR that exhibits oil repellency. Dr. Golovin's research group at UBC has teamed with Arc'teryx for this endeavor, in order to develop the first oil-repellent textile finish that is PFC-free. Golovin's group has recently discovered that nano-silicones can repel oil even though typical silicone materials get completely wet by oils. This project will explore how nano-silicones can repel oils, how these nano-silicones can be applied to textiles, and how this new textile finish can be made durable enough to meet Arc'teryx's performance needs. By the end of this 36-month project it is expected that a PFC-free textile finish, based off of nano-silicone technology, will be ready for mass production and application in all of Arc'teryx's textile mills.******
