Under projektarbejdet blev det kendt, at tilsætningen af de rene rensevæsker ofte er meget begrænset, fordi genvindingen fra renseforstærkerne i forbindelse med destillationsprocessen, erstatter tilsætning af yderligere rensevæske.
During the project work, it became known that addition of pure cleaning fluids is often very limited and that the distillates function as cleaning fluid in practice.
5.2 Analyseprogram og -metoder
5.2 Analysis programme and methods
De udvalgte produkter er analyseret for indhold af følgende stoffer og stofgrupper:
The selected products have been analysed for the following chemicals and groups of chemicals:
1. Flygtige organiske forbindelser
1. Volatile organic compounds
Der er foretaget en screening for indhold af flygtige organiske forbindelser i produkterne.
A screening has been carried out for volatile organic compounds in the products.
Der er for alle produkter foretaget kvantitativ bestemmelse af indhold af kulbrinteblandinger, glycolethere (Rynex) og chlorerede opløsningsmidler.
For all products, a quantitative determination of the content of hydrocarbon compounds, glycolether (Rynex) and chlorinated solvents has been made.
Analyserne er foretaget ved gaskromatografisk analyse på fortyndede opløsninger af de indhentede produktprøver.
The analyses were made as gas chromatographical analyses of solutions of the product samples.
Det fremgår af sikkerhedsdatabladene for flere af produkterne, at produkterne indeholder nonioniske tensider.
It appears from the safety data sheets for several of the products that the products contain non-ionic tensides.
Disse nonioniske tensider kan omfatte octyl- og nonylphenolpolyethoxylater.
These non-ionic tensides can include octyl and nonylphenolpolyethoxylates.
Da octyl- og nonylphenolpolyethoxylater kan nedbrydes til nonylphenol, som er svært nedbrydeligt og har vist hormonlignende effekter, er det valgt at medtage disse i analyseprogrammet.
As octyl and nonylphenolpolyethoxylates can be decomposed to nonylphenol, which cannot degrade easily and has shown harmone-like effects, it was decided to include these in the analysis programme.
Prøverne er analyseret for indhold af nonyl- og octylphenolpolyethoxylater ved specifik analyse.
It was analysed if the samples contained nonyl and octylphenolethoxylates, using a specific analysis.
Kemiske rensevæsker med indhold af tetrachlorethylen angives at kunne indeholde stabilisatorer i form af alkylaminer (Kemikalier og Sikkerhed, 2002).
Chemical cleaning fluids containing tetrachlorethylen may contain stabilizers in the form of alkyl amines (Kemikalier og Sikkerhed, 2002).
Der findes ingen tilsvarende oplysninger for kulbrinte- eller glycoletherbaserede rensevæsker.
No corresponding information is available for hydrocarbon or glycolether-based cleaning fluids.
For at undersøge om tilsætning af denne type stabilisatorer også kan være tilfældet for de alternative rensevæsker er der foretaget en screening for alkylaminer.
To investigate if this kind of stabilizers is also added to the alternative cleaning fluids, a screening for alkyl amines has been carried out.
Der er medtaget referencer for en række glycolethere, n-octan, n-triacontan samt tetrachlorethylen.
Internal standards have been included for glycolether, n-octane, n-triacontane and tetrachlorethylen.
For alkylaminer medtager metoden flygtige og semiflygtige forbindelser.
For alkyl amines, the method includes volatile and semi volatile compounds.
I bilag 7 er vedlagt en detaljeret beskrivelse af de anvendte metoder.
Please see appendix 7 for a detailed description of the methods used.

6.1 Introduktion til residualindhold
6.1 Introduction to residual content
Restmængden i tøj efter rensning kaldes også residualindholdet og kan består af en blanding af flygtige og ikke-flygtige komponenter.
Dry-cleaned clothes contain chemical residues that were not removed during the drying process of the dry-cleaning machine.
De flygtige komponenter kan afgives til den omgivende luft, og ad denne vej udgøre en risiko for eksponering.
These residues are also called the residual content and can consist of volatile and non-volatile components.
De ikke-flygtige komponenter kan via hudkontakt og indånding af tekstilstøv blive optaget i organismen.
The volatile components can be liberated to the surrounding air and in this way constitute a risk of exposure.
Sammensætning og størrelse af residualindholdet i renset tekstil er bl.
The non-volatile components can be absorbed by the organismn via skin contact and by breathing in textile dust.
En eventuel efterbehandling har også vist sig at kunne påvirke residualindholdet.
The volume of clothes and the textile type apparently also have an influence on the residual content.
6.1.1 Bestemmelse af residualindhold
6.1.1 Determination of residual content
Miljøstyrelsen har i forbindelse med Miljøprojekt 686/2002 foretaget bestemmelse af residualindholdet af udvalgte komponenter fra hhv. kulbrinte- og Rynex-rensevæske (Miljøstyrelsen 2002a).
In connection with Environmental Project 686/2002, the Danish Environmental Protection Agency has determined the residual content of selected components from hydrocarbon and Rynex cleaning fluid respectively (the Danish Environmental Agency, 2002a).
Ved klimakammerforsøgene blev det konstateret, at emissionen udviste et forløb, der kunne modelleres ved en eksponentiel henfaldskurve.
During the tests in the climatic chambers, the emission showed a progress that could be modelled by a curve of exponential decay.
Dette kurveforløb er tilsvarende kurveforløbet fundet i et andet Miljøprojekt for emissionen for tetrachlorethylen-renset tekstil (Miljøstyrelsen 2001).
This curve is identical to the curve of the emission for tetrachlorethylen dry-cleaned textile (the Danish Environmental Protection Agency, 2001).
Emissionen som funktion af tiden kan således angives som:
The emission as a function of time can be stated as:
Initial emissionsrate, mg/m 2h
Initial emission rate, mg/m 2h
De emissionsbestemmende parametre kan bestemmes ved klimakammerforsøg på rensede tekstiler.
The emission determinative parameters can be determined by testing drycleaned textiles in a climatic chamber.
Residualindholdet på starttidspunktet fås ved at integrere ovennævnte funktion fra t=0 til uendelig og kan beregnes som vægt/vægt%.
The residual content at the starting time is obtained by integrating the above function from t=0 to infinite and can be calculated as weight/weight%.
Residualindholdet af ikke-flygtige komponenter kan bestemmes ved forskellige ekstraktion af tekstilprøver efter rensning.
The residual content of non-volatile components can be determined by different types of extraction and analysis of textile samples after dry-cleaning.
Ved disse metoder bestemmes alene residualindholdet som vægt/vægt%.
Using these methods, the residual content is determined as weight/weight%.
De nedenfor refererede residualindhold er residualindhold efter rensning og formbehandling, dvs. presning.
The below residual content is residual content after chemical dry-cleaning and shaping, i.e. pressing.
I et projekt under Miljøstyrelsen blev der foretaget klimakammerforsøg for forskellige tekstiler renset i Rynex- eller kulbrinte-renseri (Miljøstyrelsen, 2002a).
In a project made by the Danish Environmental Protection Agency, different textiles dry-cleaned in Rynex or hydrocarbon dry-cleaning shops were tested in climatic chambers (the Danish Environmental Protection Agency, 2002a).
Det beregnede residualindhold er angivet som % af vægten.
The calculated residual content is stated as % of the weight.
Arealet er beregnet som arealet af en enkeltside af hhv. frakke og habit.
The area is calculated as the area of one side of a coat and suit respectively.
6.2.1 Udvælgelse af rensemetoder og tekstiler
6.2.1 Selection of dry-cleaning methods and textiles
Renseriejerne har givet et skøn over den andel af kilorens, som foretages som rensning.
the dry-cleaning shops have estimated the part of dry-cleaning per kilo that is carried out as chemical dry-cleaning.
Flere af renseriejerne oplyser, at de generelt fraråder kunderne at anvende kilorens som rensning, grundet det forholds, at tekstilerne kan lugte, såfremt det ikke formbehandles (presses).
Several of the owners of the dry-cleaning shops inform that they generally dissuade the customers from using cleaning per kilo as chemical dry-cleaning as the textiles may smell if they are not shaped (pressed).
dre renseriejere påpeger, at behovet for kilorens er meget begrænset, idet størstedelen af det indleverede tøj er garderobe, som naturligt kræver en presning.
Other dry-cleaning shop owners point out that the need for dry-cleaning per kilo is very limited, as most of the clothes to be dry-cleaned require pressing.
Denne forbrugerrådgivning fra renserierne afspejles i besvarelserne, jf. bilag 2, idet kilorens kun andrager få procent af renseriernes produktion.
This consumer advice from the dry-cleaning shops is reflected in the responses (please also see appendix 2), as dry-cleaning per kilo only amounts to a few per cent of the production of the dry-cleaning shops.
Det er derfor i denne undersøgelse valgt at lade rensningen foregå ved almindelig kemisk rens med for- og efterbehandling, dog uden imprægnering.
In this investigation, dry-cleaning is therefore carried out as ordinary chemical dry-cleaning with pre-treatment and final treatment, but without waterproofing.
Kriterierne for udvælgelse af tekstiler til forsøgene har været følgende:
The criteria of the selection of textiles for the tests were as follows:
Renseriejerne blev forespurgt, hvorvidt det var almindeligt at foretage kemisk rensning af dyner, rullemadrasser o. lignende.
The owners of the dry-cleaning shops were asked if it is normal to chemically dry-clean eiderowns, mats, etc.
Alle renseriejere oplyste, at de ikke foretog rensning af dyner og rullemadrasser, idet vådrensning giver bedre resultater.
All the owners of the dry-cleaning shops informed that they did not dry-clean eiderdowns and mats, as ordinary wet cleaning gives a better result.
Det er derfor valgt ikke at anvende dyner og rullemadrasser som forsøgstekstiler.
It has therefore been decided not to include eiderdowns and mats as test textiles in the investigation.
Ved forespørgsel om hvilke tekstiler, der bæres kropsnært eller tæt på ansigtet og som typisk renses, blev der fra flere renseriejere peget på benklæder, kjoler samt jakker og frakker.
To the question which textiles are clinging or worn close to the face and which are typically chemically dry-cleaned, several of the owners of the drycleaning shops answered trousers, dresses, jackets and coats.
Begrundet i ovenstående besvarelser blev det valgt at anvende en kjole, en jakke og et par benklæder som forsøgstekstiler.
On the basis of the above responses, it was decided to use one dress, one jacket and one pair of trousers as test textiles.
Butikkerne var ikke beliggende tæt på renserier.
The shops are not situated near to any dry-cleaning shops.
Tabel 6.2 giver en oversigt over de valgte tekstiler.
Table 6.2 gives an overview of the selected textiles.
Tabel 6.2: Anvendte tekstiltyper Jakke og benklæder
Table 6.2: Used textile types Jacket and trousers
28% uld, 69% polyester, 3% lycra
28% wool, 69% polyester, 3% lycra
6.2.2 Udvælgelse af pletter
6.2.2 Selection of spots
For at sikre at tekstilerne blev pletrenset forud for den egentlige rensning skulle de påføres pletter.
To make sure that the textiles were spot-cleaned prior to the actual drycleaning, they should be provided with spots.
Pletterne skulle være ”genstridige” pletter, som almindeligvis kræver væsentlig forbehandling, dvs. kræver et væsentlig forbrug af pletfjernere.
· The spots should be ”stubborn” spots that normally require considerable pre-treatment, i.e. that require a substantial consumption of spot removers.
Renseriejerne pegede på madpletter som f.eks. frugtsaft, æg og lignende, som værende genstridige.
The owners of the dry-cleaning shops selected food spots such as fruit juice, egg, etc. as being stubborn.
Ydermere blev det oplyst, at gamle pletter var vanskelige at fjerne end nye pletter.
Furthermore, they informed that it is more difficult to remove old spots than new spots.
Det Nordisk Miljømærke (Svanen) omfatter miljømærkning af tekstilvaskemidler (Nordisk Miljömärkning, 2001).
The Nordic Environmental Label (the Swan) includes environmental labelling of textile detergents (Nordic Environmental Labelling, 2001).
Kriteriedokumentet beskriver valg af standardiserede pletter for vasketest.
The criterion document describes standardized spots to be used for washing tests.
Det blev valgt at anvende samme plettyper ved de foreliggende forsøg.
It was decided to use the same spot types for the present tests.
De valgte plettyper fremgår af nedenstående tabel 6.3 som plet nummer 1, 2, 5 og 6.
The selected spot types appear from table 6.3 below as spot number 1, 2, 5 and 6.
Miljøstyrelsen ønskede derudover at supplere med æg og solbærsaft (type 3 og 4 nedenfor).
The Danish Environmental Protection Agency wanted to supplement with egg and black currant juice (type 3 and 4).
Flydende kakao Æg
Soot/oil mixture Cocoa
6.2.3 Udvælgelse af renserier
6.2.3 Selection of dry-cleaning shops
Da alle renserier som udgangspunkt blev vurderet som velegnede til forsøgene, blev der i udvælgelsen lagt vægt på den fysiske lokalisering af renserierne samt hvorvidt renseriejeren kunne varetage udtagningen af destillat uden supplerende teknisk bistand.
As all dry-cleaning shops were basically found qualified for the tests, great importance was attached to the physical location of the dry-cleaning shops and if the owners of the dry-cleaning shops could take samples of the distillate without any technical assistance.
