Evaluation of Detergency Using Artificially Soiled Multifiber Fabrics

Abstract

The evaluation of textile detergency was carried out using artifi cially soiled multifi ber adjacent fabric (MFF) composed of six different warp regions. The MFF soiled with model water-soluble, oily or particulate contaminant was cleaned in water, water/ethanol (1/1 in volume ratio), ethanol and n-decane with the stirring as a mechanical action. The detergency of the each fi ber region was determined from the change in surface refl ectance of the corresponding region due to cleaning. The soil removal was strongly dependent on contaminant, fi ber and liquid species, indicating that the detergency was dominated by the dissolution of the contaminant into the washing liquid and the affi nity between the contaminant and the fiber surface. The addition of alkali and surfactant to water or the solubilization of water into n-decane considerably increased the soil removal. The experimental results were not in contradiction with common and well-known knowledge about textile washing. Therefore, the artifi cially soiled MFF can be utilized for the detergency evaluation for textiles.

The effect of fabric movement on washing performance in a front-loading washer III: Focus on the optimized movement algorithm

“…Thus, washing effects are considered difficult to explain exactly in respect of the mechanical washing mechanism, such as fabric movements, mechanical action by the washers, water flow dynamics, and so on. It eventually causes difficulties in explaining the overall washing mechanism, such as new washing methods, [6][7][8][9] washing evaluation methods, [10][11][12][13][14] and simulations on washing. [15][16][17][18][19][20] Therefore, there is a need for research on the effects of mechanical action, such as fabric movement on washing efficiency, for better understanding the overall washing mechanism.…”

A Surface Plasmon Resonance Optical Fibre Sensor for Testing Detergent Cleaning Efficiency

“…By using fluorescence measurements the detergency of surfactants has been evaluated quantitatively for actual plant operation [5]. Additionally, another method used surface reflectance for evaluating soiled multifibre fabrics for textile detergency [6]. The lack of sensitivity of these spectroscopic methods results from their inability to distinguish between fluorescent whitening agents and other fluorescent compounds.…”

Experimental Analysis of Detergency Phenomena and Investigation of a Next-generation Detergency System

“…The evaluation of textile detergency was carried out using artificially soiled multifiber adjacent fabrics MFFs composed of six different warp regions 23 . The MFFs soiled with particulate, oily, and water-soluble soils were cleaned by stirring at 600 rpm in water containing NaOH, AS, and n-decane solubilized in water.…”
