Abstract

This paper presents an experimental study and proposes an empirical model on the residual water content of a cotton load during the extraction phase of professional washing machines. Literature lacks data about spinning dewatering performances and thus a method is proposed to measure and predict water retention with respect to the main parameters that affect the washing process. The paper first provides a survey about retention models developed for different applications. It then introduces a new methodology to estimate residual moisture content as a function of time and centrifugal parameters, which avoids time consuming measurements. The methodology is proposed with respect to a customised washing cycle, which enables experimental validation with commercial washing machines. A scaling analysis is finally performed to verify the influence of the drum shape on retention performances. Results confirm the validity and versatility of the proposed model on a wide range of professional washing machines.

摘要

本文介绍了一项实验研究，并提出了一个关于专业洗衣机提取阶段棉花负载残留水分的经验模型。文献缺乏关于纺纱脱水性能的数据，因此提出了一种方法来测量和预测关于影响洗涤过程的主要参数的保水性。本文首先对针对不同应用程序开发的保留模型进行了调查。然后，它引入了一种新的方法来估计残留水分含量作为时间和离心参数的函数，从而避免了耗时的测量。该方法是针对定制的洗涤周期提出的，它可以使用商用洗衣机进行实验验证。最后进行缩放分析以验证滚筒形状对保留性能的影响。结果证实了所提出模型在各种专业洗衣机上的有效性和多功能性。
