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

滚筒式烘干机床单用于提供织物护理功能，包括在国内衣物烘干过程中减少静电、柔软、去皱和清新。大约2克活性物质从基材转移，以提供这些好处，而不会明显地污染织物。为了最大限度地提高效率，在干燥周期的时间范围内，必须将高比例的活性均匀地沉积到织物的孔隙结构中。这一过程受每个滚筒式干燥机的设计和操作、洗涤织物的数量、组成和水分含量以及干燥机片材的活性和基材性质的影响。将开发模拟干燥动力学和活性物质转移的织物干燥和处理模型，以优化使用烘干机片材时的烘干机效益。这些将使用包括正电子发射粒子跟踪在内的实验技术进行验证，这是对以前对洗衣机动力学所做工作的扩展。

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.
