In recent years, there has been a growing interest in the application of ultrasonic cleaning techniques to textiles. However, the impact of textile properties on the cleaning performance has not been studied yet. This paper addresses this gap by systematically investigating the influence of different factors including fabric type, dirt type, and ultrasonic frequency, on the cleaning efficacy of textiles. To this end, four distinct fabric types, characterized by variations in texture, fiber material, and area density, were selected for experimentation. Additionally, two distinct dirt types, derived from chocolate milk and a carbon black-paraffin mixture, were introduced to assess their specific effects on ultrasonic cleaning. To analyze the impact of ultrasonic frequency, two transducers operating at frequencies of 19.5 Hz and 32.5 Hz were designed and fabricated. The quality of cleaning on the fabric samples, stained with the aforementioned dirt types, was evaluated using a full factorial experimental design. Measurement of washing quality was carried out employing a spectrophotometer. The findings of this investigation reveal that an increase in frequency is associated with a reduction in cleaning performance. Furthermore, the type of fabric texture directly influences the extent to which dirt stains are removed from the fabric. The choice of fiber material plays a crucial role in determining the textile's hydrophilic or hydrophobic characteristics, which, in turn, significantly impacts the bonding between textile yarn and various types of dirt. Consequently, the overall cleaning efficiency of the textile is affected by these interrelated factors. [ABSTRACT FROM AUTHOR] |
