“…[21] , [34] Additionally, agitation during drying would be more crucial to the wrinkling process because agitation is easy to cause unevenness in fabric stress and unevenness of deformation. At this moment, molecular chains fracture and recombine continuously as the tumbling action keeps going on during the drying process.…”

“…As drying proceeds, migration of moisture within the fabric cannot compensate for the evaporation of free water on fabric surface, and the free moisture inside fabric gradually declines to the critical moisture content. [21] Subsequently, the drying rate decreases and this indicates the start of stage 3. In our case, the critical moisture content of fabric decreased from around 55% to around 17%.…”

“…During the drying process, fabric continuously absorbs heat from the heated air, while moisture in the fabric is also continuously removed to the drying air, and thus, temperature and moisture content of fabric, temperature and humidity of air are all variable in the drying process. [21] , [28] Monitoring key process parameters during fabric drying are important to understanding the heat and moisture transfer mechanism of the drying process.…”

“…[16] , [21][22][23] Since fabric is the object served by dryers, the appearance of fabric after drying should be considered as well as energy consumption. [24] Therefore, it is reasonable to adjust key drying parameters by stages based on the drying characteristics in each stage, and then achieve the purposes of better appearance of drying loads and understanding of woven cotton fabric wrinkling mechanism during domestic tumble drying.…”

The domestic tumble dryers are becoming indispensable household appliances and responsible for up to 10% of the total residential energy use in developed countries. However, their energy efficiency is low. In this paper, the development of a multi-sensor computer-controlled prototype platform for fabric drying is described for improving the efficiency of dryers. The prototype platform enables the real-time control and recording of key drying parameters including heater power, air flow velocity, rotating speed of drying drum and drying cycle time. These parameters are automatically adjusted according to the exhaust air humidity instead of the temperature which is used traditionally. Additionally, a new drying model of dividing the drying process into 4 stages based on the humidity of the exhaust air has been investigated in order to further increase the energy saving. The performance of this staged drying model is experimentally evaluated in respect to energy consumption, drying time, and the smoothness of fabric after drying. The results clearly indicate that the staged controlling of heating power input not only decreases energy consumption by 21.5% but also improves the fabric smoothness by 0.9 grade compared to using a single heating power input for the whole drying process. The research outcome can enable the design and production of new dryers that are more energy efficient and lead to dried clothes that require less ironing, which in turn further reduces energy consumption.

To evaluate the performance degradation of fabric drying in domestic air-vented dryer, the appearance, mechanical, and microscopic properties of the wool fabric after different drying cycles were studied. Pilling and dimensional stability tests were performed according to established international standards. Microscopic studies were carried out by Scanning Electron Microscopy (SEM) and X-ray (XRD). The results show that pilling is the dominant damage mechanism and gradually increased during lower number of drying cycles (0-10 cycles). The results of dimensional stability showed that the highest dimensional shrinkage of knit wool fabric was first five drying cycles, and then increased at a relatively slow rate with the increase in drying cycles. And fabric shrinkage takes place mainly in the warp direction. The SEM images of wool fiber showed that the scales on the fiber surface were intact in the first 15 drying cycles but start to flake after 20 drying cycles. In the drying process, fabrics can suffer several fractures such as cut fracture, split fracture, partial fracture and distortion and even scale flaking and interior structural distortion of fiber. The damages occur quite randomly, but complexity and severity of damages increased with increase in drying cycles. XRD analysis showed that drying had little effect on fiber crystallinity, indicating that drying only leads to changes in the physical properties of wool fabrics instead of changes in the chemical composition of the fiber. And found SEM analysis is not only an effective method to characterize the change in the surface morphology of the fibers resulting from the drying treatments, but also explain the cause of fabric performance degradation such as pilling and strength reduction during drying.
