“…Akcabay et al (2014) carried out simulation work to quantify various flows and shear stresses during conventional laundering. Various studies have confirmed the critical importance of hydrodynamic action, working together with detergent components, in bringing about effective washing (Li and Hardin 1998;Caparrós et al 2012;Muir et al 2013;Han et al 2015;Bueno et al 2019). Notably, hydrodynamic shear can be expected to provide the energy input that is required by such detachment mechanisms as roll-up and snap-off (Dillan et al 1979;Miller and Raney 1993).…”

“…Stains can be defined as persistent, undesired colorants (Kert and Simoncić 2008;Ponnusamy et al 2008;Pukale et al 2017;Bueno et al 2019). Many of them are organic compounds having strong ability to absorb light (Luxbacher et al 2008).…”

“…Detergent action takes time. Several articles have considered the duration of exposure to detergent solution needed to achieve suitable washing results (Dillan et al 1980;Fujii et al 1986;Burkinshaw and Anthoulias 1996;Herrera 1996;Hoshino et al 2000;Komaki et al 2002;Kaewpukpa et al 2008;Yun and Park 2015b;Pukale et al 2017;Bueno et al 2019;Isaka et al 2021). It is well known that processes such as enzymatic hydrolysis take time to reach sufficient completion to reach desired goals (Hoshino et al 2000).…”

“…Release of solid particles can be much more difficult when they are physically entrapped within the structure of fibrils or lumens within a textile material (Schott 1969;Kissa 1981;Obendorf 2004). In addition to the mechanical entrapment, such locations also may be protected from the influence of hydrodynamic forces (Bueno et al 2019). Thus, Obendorf (2004) observed that the physically entrapped dirt was likely to remain in the textiles after laundering.…”

The release of soils and impurities from cellulosic surfaces plays a critical role in such processes as the laundering of clothes and the deinking of wastepaper pulps. This article reviews publications that provide evidence about factors that affect such release and the mechanisms by which such factors operate. In general, cellulosic substrates provide advantages for the release of contaminants due to their hydrophilic nature and due to their permeability, allowing the transport of surfactants to contact interfaces with dirt. However, the same permeability of cellulosic material also provides opportunities for contaminants to work themselves into internal crevices and pores, from which they are difficult to remove. The article also reviews aspects of theory related to detergency and how those theories relate to the laundering, deinking, and purifying of substrates based on cellulose and related plant materials. Cellulose and some of its derivatives also can play a role in detergent formulation, especially as builders or as finishes placed on textile surfaces, which sometimes aid in the release of dirt.

“…Research on the mechanical force of washing machines has been conducted from the viewpoint of simulating the movement of clothes by rotation (Cho et al, 2017; Lee et al, 2008; Yun et al, 2013), kinetics of the washing stain removal process discussing separately for the inside and outside of the thread (Bueno et al, 2019), and analyzing frictional action on washing on fabric dye loss (Cai et al, 2016). The effects of liquid flow on alternating flow cleaning with fine bubbles (Ushida et al, 2012) and the effects of mechanical forces on CO 2 dry cleaning of clothes (van Roosmalen et al, 2003) were also studied.…”

Probability density functional method was used to determine whether interaction between mechanical force and chemical action in cleaning was an additive effect, a synergistic effect, or an offsetting effect. As a soiled sample, iron (III) oxide soiled fabric, Sudan IV soiled fabric, commercially available artificial soiled fabric containing mixed stains, etc. were used and washed with a tergotometer. Mean value μ rl and standard deviation σ rl of the cleaning force distribution were calculated by using probability density functional method, and the interaction was judged using Δμ rl which is the difference between μ rl obtained under the two conditions. As results, additive effects between the mechanical force and the pH effect were confirmed in the cleaning of iron (III) oxide soiled fabric and commercially available artificially soiled fabric, and an additive effect between the mechanical force and the effect of the surfactant concentration was confirmed in the cleaning of Sudan IV soiled fabric. Therefore, it was presumed that an additive effect is often established between the mechanical action and the chemical action in cleaning, rather than a synergistic effect or an offsetting effect.
