摘要织物在滚筒式干燥机中的横向运动对织物的热质传递起着重要的作用。然而，由于缺乏有效和准确的实验方法，很少有人关注这种动态行为。本文介绍了如何利用高速检测系统来跟踪示踪织物染黄，因为它是在其他织物在不同的干燥条件下翻滚，在国内转筒式烘干机的目的是识别织物的横向运动。实验结果表明，织物运动是一个复杂的过程，不仅受织物尺寸的影响，而且受干燥负荷质量的影响。大多数织物主要分布在两个区域，即松散区域和分散区域。增加分散区域的尺寸，其中织物通过旋转滚筒的运动被投射到空气中，也扩大了织物与周围空气之间的接触面积，并增强了纺织品的混合运动。这对传质和传热以及防止结垢有积极的贡献。织物尺寸为80 cm × 80 cm，质量为3 kg时，干燥效率较高，外观平整度较好。高速检测系统发现，织物尺寸和负载质量的特定范围会导致织物混合和空气与织物接触的增加。
Abstract The transverse motion of fabrics in domestic tumble dryers plays an important role in fabric heat and mass transfer using hot air. However, owing to a lack of effective and accurate experimental methods, little attention has been paid to this dynamic behavior. This paper describes how a high-speed detection system was utilized to track a tracer fabric dyed yellow as it was tumbled amongst other fabrics under different drying conditions, with the aim of identifying transverse fabric motion in a domestic tumble dryer. The experimental results demonstrate that fabric motion is complicated and can be affected by the size of fabrics as well as by drying load mass. Most fabrics inhabited two main regions, the bulk region and the disperse region. Increasing the size of the disperse region, where fabrics are projected into the air by the motion of the rotary drum, also expands the contact area between the fabric and the surrounding air, and augments the mixing motions of textiles. This contributes positively to the mass and heat transfer, and to the prevention of wrinkling. A higher drying efficiency together with a better smoothness appearance was observed with a fabric size of 80 cm 80 cm and a mass of 3 kg. The high-speed detection system identified that specific ranges of fabric size and load mass led to increased fabric mixing and air-fabric contact.
