Mechanistic understanding and design of sustainable solid fabric enhancer

该项目将调查干燥板涂料的配方和作用，这是宝洁公司的主要业务，销售额为120亿美元。烘干机既有助于干燥过程，又通过在滚筒烘干机内将配方固体材料从床单转移到衣服上，赋予织物吸引人的质地和香气。然而，配方设计与传递效率之间的关系尚不清楚；更好的理解将导致更少的浪费和更有效的干燥，节省材料和能源。伯明翰和宝洁之前的研究工作是通过测量干燥机中的流量来研究干燥[干燥技术，2021doi.org/10.1080/07373937.2021.1918706]]，并通过研究大气和纳米尺度的转移过程，使用原子力显微镜和微操作探针，但仅限于目前的配方，以建立产品作用的基础。新项目将利用已建立的测量能力、基础知识和可能的行动模式来调查产品配方、产品制造过程和床单和衣服之间的传递效率之间的关系。将研究不同的配方，以更好地了解每种成分在混合物中的作用。目的是确定制造工艺和产品性能之间的关系，例如，更好地理解如何控制产品粘性、附着力和转移轮廓。支持产品性能的基础工程科学将使用领先的界面设备进行识别，包括AFM， DVS，纳米识别，微操作和高光谱SWIR成像系统。

The project will investigate the formulation and action of dryer sheet coatings thatis a major P&G business with sales in the region of $12 Billion Pa. Dryer sheetsboth assist the drying process and impart attractive texture and aromas to fabricsby transferring a formulated solid material from sheet to clothes within a tumbledryer.The governing relationship between formulation design and transfer efficiency isnot however well understood; better understanding would lead to less waste andmore efficient drying, saving both material and energy.Previous work between Birmingham and P&G studied drying both by measuringflows in working dryers [Drying Technology, 2021doi.org/10.1080/07373937.2021.1918706] and by studying the transfer process atmeso- and nano- scales, using AFM and micromanipulation probes, but wasconstrained to the current formulation to establish the basis of product action.The new project will capitalize on the established measurement capabilities,fundamental knowledge, and possible Mode of Actions to investigate therelationship between product formulation, product manufacturing processes, andtransfer efficiency between sheet and clothes. Different formulations will bestudied to better understand the role of each component in the mixture.The aim is to identify the relationship between manufacturing processes andproduct performance, leading for example to better understanding of how tocontrol product tackiness, adhesion, and transfer profile. The fundamentalengineering science that underpins product performance will be identified usingleading-edge interfacial equipment, including AFM, DVS, nanoidentation,micromanipulation, and hyperspectral SWIR imaging system.
