Mechanistic understanding and design of sustainable solid fabric enhancer

该项目将调查配方和行动的干燥机板涂料，这是一个主要的宝洁公司的业务，销售额在该地区的12亿美元。干燥纸既有助于干燥过程，又通过在滚筒式干燥机内将配方固体材料从纸转移到衣服上，从而赋予织物有吸引力的质地和香味。更好的理解将导致更少的浪费和更有效的干燥，既节省材料又节省能量。Birmingham和P&G之间的先前工作通过测量工作干燥器中的流量来研究干燥[Drying Technology，2021doi.org/10.1080/07373937.2021.1918706]并通过使用AFM和微操作探针研究中尺度和纳米尺度下的转移过程，但受限于当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，和可能的作用模式，以调查产品配方，产品制造工艺，和床单和衣服之间的转移效率之间的关系。我们将研究不同的配方，以更好地了解混合物中每种成分的作用。目的是确定制造工艺和产品性能之间的关系，例如，更好地了解如何控制产品的粘性、附着力和转移特性。支撑产品性能的基础工程科学将使用前沿的界面设备进行识别，包括AFM、DVS、纳米压痕、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.
