Thermo-physical effects of tumble drying on the delivery of fabric care benefits: Fabric drying and treatment models

滚筒式烘干机片用于提供织物护理益处，包括在家用衣物干燥期间减少静电、软化、去毛刺和清新。大约2克的活性材料从基底转移以提供这些益处而不会明显地污染织物。为了使效率最大化，高比例的活性物质必须在干燥循环的时间尺度上均匀地沉积到织物的孔结构中。该过程受每个转筒式干燥机的设计和操作、洗涤织物的数量、成分和含水量以及干燥纸的活性和基质性质的影响。织物干燥和处理模型模拟干燥动力学和活性材料转移将开发，以优化通过干燥机的好处时，使用干燥机片。这些将使用实验技术进行验证，包括正电子发射粒子跟踪，在洗衣机动力学以前所做的工作的扩展。

Tumble dryer sheets are used to deliver fabric care benefits including static reduction, softening, de-wrinkling and freshening during domestic clothes drying. Approximately 2 grams of active material is transferred from a substrate to deliver these benefits without visibly staining the fabrics. To maximise efficiency a high proportion of the active must be deposited homogeneously into the pore structure of the fabric over the time scale of the drying cycle. The process is affected by the design and operation of each tumble dryer, the quantity, composition and moisture content of the washed fabric and the active and substrate properties of the dryer sheet. Fabric drying and treatment models simulating drying kinetics and active material transfer will be developed to optimise through the dryer benefits when using dryer sheets. These will be validated using experimental techniques including Positron Emission Particle Tracking, extending on the previous work done for washing machine dynamics.
