Benchmark Study
Update september 2014Over the last 2 decades, there have been many technological developments
in the field of alternative cleaning technologies. These developments may be
in the field of new solvents, new or improved machine technology or new or
improved detergents. Today the dry cleaner can choose from siloxane D5, liquid
CO2, professional wetcleaning, dibutoxymethane, iPura siloxane D5, iPura HCS
and other solvents.
This is not without a reason, as the pressure worldwide on the use of
perchloroethylene if the industry is not adopting Best Practices rapidly enough.
At the same time developments of good alternatives for perchloroethylene are
looked for. Wet Cleaning is one of them. Over the last years newly advanced
wet cleaning systems have been introduced.
A study on the cleaning performance of today’s established wet cleaning
systems has been conducted by TKT. The results are presented in this paper
tKt TKT is the Dutch technical knowledge
centre for the textile care industry, for

In Solvetex IV the cleaning performance, the appearances and finishing ability is evaluated for the Wet cleaning systems/chemical
suppliers: Electrolux/Concord Textile, Miele/Kreussler, Girbau/Seitz and Girbau/Büfa to supply up-to-date information on the state of
the art performance of Wet cleaning to the professional textile cleaning industry.
ConclusionGood cleaning performances are obtained with the Wet cleaning systems evaluated for water soluble stains and limited cleaning
performance for non water soluble stains. Some differences in cleaning performances and stain removal are identified between the
different systems. The jacket of synthetic material can be cleaned and finished with a good result. For the woollen jacket, especially
the fused interlining resulted in wrinkles and bubbles for all Wet cleaning systems evaluated. Extra finishing attention is therefore
required to be able to restore the deformation and deliver high quality finishing performance. Differences between the Wet cleaning
systems are noticed in the amount of bubbles and winkles and the ease to remove them. The shrinkage is limited after the drying and
finishing processes for all Wet cleaning systems. Standard finishing procedure can reduce the deformation of the textiles significantly.
An important difference is the drying procedure and the use as complementary to dry cleaning or as replacement of dry cleaning for
the overall productivity and results. The results will be discussed in more detail in this report.
IntroductionIn the previous Solvetex projects, TKT evaluated the performance of alternative solvents. Beside the developments of solvents other
systems are developing as well. One of the major developments the past years are the Wet cleaning systems. Due to changing
legislation in different countries and the different needs of customers Wet cleaning is more and more applied. Wet cleaning systems are
based on water as solvent in combination with chemicals, reduced mechanical action, specialized equipment and specific programs.
Currently many different Wet cleaning systems are on the market, each with their own combination of equipment, chemicals and
programs. One of the most discussed items is the ability of a Wet cleaning system to replace dry cleaning equipment. This question is
difficult to answer due to the many differences in dry cleaning operations. Nevertheless this project will evaluated four different state
of the art Wet cleaning systems on cleaning performance, appearances like shrinking, greying, looks and finishing ability to present
actual results on Wet cleaning.
MaterialsThe cleaning performance is studied under real life conditions, by means of a number of test articles and sample materials, to
determine the effect on appearance like shrinking, greying and stain removal. The test methods in all the Solvetex projects are the
same and therefore comparable. Three model test swatches of each type will be cleaned every cycle and each cleaning cycle will
be carried out three times to obtain representative results. The load exists of the textile package, the test swatches and additional
standardized textiles to meet the required (optimal) load.
Deformation and shrinkageThe textiles cleaned in the wet cleaning systems are sensitive to water. Especially the wool items can be sensitive to deformation or
shrinkage. The test jackets are measured before the test, after the drying steps and after the finishing steps. The lengths of the arms
cleaning cycles for all systems except for the Girbau/Büfa system, probably because no tumble drying was applied.
General remarksThe results of the experiments are valid for the test materials used. The use of other textile materials or quality can result in different
behaviour and results. Except for the Electrolux/Concord system the Wet cleaning systems were used as complementary system to
dry cleaning. The Electrolux/Concord system was used as complete replacement of the solvent system. Based on the textiles and the
soil a choice between Wet cleaning and solvent cleaning was made on the location that used Wet cleaning as complementary system.
All the shops have extensive experience, knowledge and skills of textile materials, stains and the processes. One of the most positive
experienced benefits by the customers is the neutral or pleasant smell of the garments after cleaning.
