The Impact of Liquid Surface Tension on Fabric Drying Efficiency

Abstract

This study presents an experimental investigation of the relationship between liquid surface tension and fabrics water retention in dehydration processes such as centrifuging, line drying and heat drying. Selected surfactants were used to prepare wash baths with different surface tension, and dehydrating experiments of cotton fabric after immersion in above bath were conducted. The results showed that lower surface tension is beneficial to reducing fabrics water retention by centrifuging and improving line drying efficiency and heat drying efficiency. It was assumed that water with low surface tension is easy to drop down or separate from fabric, thus improving the de-watering and drying efficiency.

The Impact of In‐situ Fabric Surface Energy on Dehydration of Fabrics

“…After dripping for 1 min, the fabric was centrifuged. The parameters of centrifugation are as follows: rotational speed (510 rpm), time of centrifugal (1 min), rate (9). Finally, the weight was taken to determine the RMC [RMC = 100 % 9 (weight centrifuged -…”

“…Recently, we investigated the influence of fabric surface properties on the dehydration of fabrics. With the treatment of cotton fabric with water repellent reagents, the dehydration efficiency as well as the drying rate increased correspondingly [9]. Usually, the surface energy in air cannot reflect the real situation in surfactant solutions.…”
