Waterproof breathable garments typically consist of multi-layer construction, comprising a durable water-repellent-coated outer shell textile, a waterproof breathable membrane, and lining material. These fabrics are bonded together to form the multi-layer structure, with pieces of fabric sewn to produce garments. To prevent leaks along seams, they are sealed with tape. This approach delivers high-performance apparel, but is limited by:* **Use of environmentally damaging chemicals.** High-performance membranes are typically manufactured from expanded polytetrafluoroethylene (ePTFE; Gore-Tex), which is waterproof, windproof, and chemically inert. However, 75% of waterproof fabrics contain toxic PFCs (per-/poly-fluorinated chemicals); "forever" chemicals that persist and bioaccumulate, causing serious health problems including cancer and birth defects(Guardian\_2022,OECD\_2013). Brands are under increasing consumer and government pressure to remove PFCs. Recent UK REACH policy is restricting PFCs(HM\_GOV\_2021), five EU countries are looking to ban PFCs by mid-2022(Chemistry\_World\_2021), and Adidas has committed to being PFC-free(ECHA\_2019).* **No sustainable end-of-life solutions.** Multi-material textiles cannot be separated and face either landfill or incineration at end-of-life, c£400 billion/year in value is lost globally from clothing underutilisation and lack of recycling(Ellen\_MacArthur\_Foundation\_2017). In landfill, plastics break down over time to produce microplastics, which are harmful and persist in the environment(OECD\_2013). During incineration, PTFE membranes used in Waterproof Breathable Textiles(WBTs) produce highly toxic hydrofluoric acid, which is converted to fluorspar in typical municipal incinerators(Aleksandrov\_et\_al\_2019).Amphibio is a London-based micro-SME founded in November 2018 by Jun Kamei, a designer and material scientist developing commercial applications for superhydrophobic porous membranes. With InnovateUK support, we will develop an innovative WBT that delivers on the triple bottom line:* **People**. Our WBT will match the performance of market leading textiles, enabling reliable waterproofing and breathability for end-users. Our WBT will enable end-users to meet their own sustainability goals, through garments that are produced from recycled feedstocks and, crucially, can be recycled at end-of-life (whereas other WBTs cannot).* **Planet**. Our mono-material WBT will be 100% recyclable and PFC-free, as well as utilising recycled and plant-based feedstocks rather than oil-derived virgin polymers, making it the world's first circular and carbon-negative WBT. Our fully-circular textile means fabric wasted during production (c20%,EPRS\_2019) and garments at end-of-life can be used for new textile rather than heading to landfill. Given our novel membrane and lamination process, our WBT will shed 20% fewer microplastics than competitor WBTs.* **Profit**. Working with leading clothing brands, our innovative material will help organisations deliver on their sustainability targets, supporting the clothing industry to reduce its environmental footprint.

防水透气服装通常由多层结构组成，完成了耐用的防水外壳纺织品，防水透气膜和衬里材料。这些织物被粘合在一起，形成多层结构，并配有织物半隔离片以生产服装。为了防止海洋泄漏，它们用胶带密封。这种方法提供了高性能服装，但受到以下方式的限制：**使用环境破坏的化学药品。**高性能膜通常是由扩展的聚氟乙烯（Eptfe; gore-tex）制造的，它是防水，防风和化学惰性的。但是，有75％的防水织物含有有毒的PFC（每/聚氟化学物质）；持续和生物蓄积的“永远”化学物质，导致严重的健康问题，包括癌症和先天缺陷（Guardian \ _2022，OECD \ _2013）。品牌正在越来越多的消费者和政府拆除PFC的压力。最近的英国涉及政策限制了PFC（HM \ _GOV \ _2021），五个欧盟国家正在寻求在2022年中禁止PFC（化学\ _World \ _2021），而阿迪达斯（Adidas）则承诺无pfc pfc for PFC（echa \ _2019）。分离并面对垃圾填埋场或感染，在寿命末，价值4000亿英镑的价值在全球范围内因不足和缺乏回收利用而损失（Ellen \ _macarthur \ _Foundation \ _2017）。在垃圾填埋场中，塑料随着时间的流逝而分解以产生有害和持续存在的微塑料（经合组织\ _2013）。在焚化过程中，用于防水透气纺织品（WBT）中使用的PTFE机制产生了高毒性的氢氟酸，在典型的市政焚化炉中转换为荧光素（Aleksandrov \ _et \ _AL \ _AL \ _2019）。用于超疏水多孔机制。在Innovateuk的支持下，我们将开发一个创新的WBT，该WBT在三重底线上提供：** People **。我们的WBT将与市场领先的纺织品的性能相匹配，为最终用户提供可靠的防水和透气性。我们的WBT将使最终用户能够通过回收原料生产的服装实现自己的可持续性目标，并且至关重要的是，可以在寿命末期回收（而其他WBT不能）。我们的单材料WBT将100％可回收且无PFC，并利用可回收的和植物性的原料，而不是油衍生的原始聚合物，使其成为世界上第一个圆形和碳含量的WBT。我们的全圆形纺织品意味着在生产过程中浪费了织物（C20％，EPRS \ _2019），生产寿命末的服装可用于新的纺织品，而不是前往垃圾填埋场。鉴于我们的新型膜和层压过程，我们的WBT比竞争对手WBT的微塑料少20％。** PROUT **。我们的创新材料与领先的服装品牌合作，将帮助组织实现其可持续性目标，并支持服装行业减少环境足迹。
