Klesforsknings Kirsi rangert blant verdens mest siterte

I alt 22 forskere ved OsloMet er på Stanford universitetets prestisjetunge liste over de to prosent mest siterte i verden, og blant dem finner vi Klesforsknings Kirsi Laitala.

Prorektor Tanja Storsul var raskt ute med å gratulere samtlige 22, og SIFO sørget for å spre det glade budskap om Kirsi blant annet på LinkedIn hvor gratulasjonene strømmet inn.

– Å være blant de to prosent mest siterte i global sammenheng vitner om at de driver svært relevant forskning, og at de har stor innflytelse i det internasjonale fagmiljøet på sine felt, sa Tanja Storsul, og vi må si oss enige.

Kirsi Laitala er forsker II hos SIFO og har jobbet med tekstilforskning siden 2001. Hun har sivilingeniørutdanning fra Tammerfors Tekniske Universitet i Finland innen tekstil, fiber og konfeksjonsteknikk og PhD fra institutt for produktdesign ved NTNU fra 2014. Hun har forsket og publisert på områder knyttet til kleskvalitet, vedlikehold, sikkerhet, miljø, design, samt passform og størrelsesspørsmål. Vi finner hennes navn i flere av de dokumentene og studiene som EU har lagt til grunn for i Tekstilstrategien, og vi finner illustrasjonen fra Review of clothing disposal reasons med tredeling av avhendingsgrunner igjen i en Joint Research Center underlagsrapport for EUs politikk uten at den er kreditert!

Flittig brukt illustrasjon fra Kirsi Laitalas forskning, også av EU.

Rangeringen er et samarbeid mellom Stanford University og analyseselskapet Elsevier, og er basert på data hentet fra den globale databasen Scopus, hvor de har plukket ut de to prosentene av forskere i verden som har publisert mest og blitt sitert flest ganger.

– Det er jo en god følelse å vite at forskningen vi har publisert blir lest og brukt av andre forskere videre. Det er en bekreftelse at det vi holder på er relevant også for andre, og det er motiverende, sier Kirsi. – Klassifiseringssystemet gjør at det er ikke så lett å finne andre på sitt eget felt, så det er vanskelig å vite hvor mange andre klesforskere er på listen. Jeg var kategorisert innen tre kategorier: Energi, Markedsføring og «Enabling & Strategic Technologies», som jo ikke treffer så godt. Det finnes ingen egen kategori for klesforskning, men jeg spottet noen kjente navn, for eksempel Kirsi Niinimäki, og innen produktlevetid så fantes Tim Cooper. I tillegg er det en del samarbeidspartnere fra NTNU der.

Det er syvende gang listen er publisert. Den kan sees ved å følge denne lenken.

Artikkel i Nasjonalmuseets Oltre Terra katalog

I sammenheng med ullutstillingen Oltre Terra på Nasjonalmuseet, som vi har skrevet en kritisk kronikk om, ble det også utgitt en katalog på norsk og engelsk. Det tok litt tid før vi fikk den overrakt, men nå som den er lest den fra perm til perm, er vi mektig imponert over det som faktisk er en gjennomarbeidet bok om forskjellige aspekter om ull og sauer.

Boken, eller katalogen, er trykket på et påkostet papir, og inneholder mange fine bilder fra rundt om i verden – og tar for seg temaer på en dyp og forskningstung måte. Litt ullnerd bør du være for å grave deg inn i innholdet, men hvis dette er noe som engasjerer, er det verdt jobben. Ingun Grimstad Klepp og undertegnede har bidratt med et kapittel om ull i Norge og i miljødebatten, et kapittel som antagelig prøver å favne for vidt, og som stadig ble redigert ned i lengde, slik at vi ikke er helt fornøyd med resultatet språklig. Men redaktøren er fornøyd, så vi har slått oss til ro med det.  Dette er en leveranse i Amazing Grazing prosjektet, og det eneste kapittelet i boken hvor norske sauer og norsk ull får skinne, iallfall litt.

De andre kapitelene dekker temaer som avl: Kan man avle både på kjøtt og ull?  Svaret er ‘ja’. Kan man avle på ull og melk (i mange land holder man sauer for melken)? Svaret er ‘nei’. Styrer mennesker eller maskiner historien, eller veves eller spinnes den? Eier vi sauene, eller er det landskapet som eier dem? Her utforskes både språket, ordene «vev», «tekst» og «å ha», og sammenhengen mellom teknikker og industrialisering, og nomader, bønder og tekstilutøvere. Domestisering er også utforsket, som kan sies å være hovedtemaet til utstillingen Oltre Terra.

Mens det i utstillingen vektes mot at vi ‘utnytter’ dyrene med veganske briller på, er tekstene i boken mer nyanserte og gir flere og gode svar. For oss i Norge, er selve ideen om transhumans, som utforskes i sammenheng med sauegjeting i Alpene, en litt fjern form for sauedrift i norsk sammenheng. Vi slipper buskapen ut i naturen og lar dem klare seg selv. Det vil si: Sauebonden er pålagt å se til dem med jevne mellomrom, men muligens ikke ofte nok, siden undertegnede to ganger har måttet melde i fra om lam på fjellet som var skadet eller som hadde satt seg fast i en myr.

En av artiklene handler om sauenes inntog i Australia og hvordan de harde hovene ødela jordsmonnet og forandret landet og naturen totalt. Det er selvsagt en trist historie, men landskapet har tilpasset seg de massive hordene, og i dag er situasjonen en helt annen, sauene er en del av å gjenopprette balansen, gjennom regenerativ beiting. Artikkelen besøker den aller første merino-gården i Australia, hvor vi også har vært, hvor vi fikk se de opprinnelige merinosauene som kom til Australia, som er mye, mye mindre enn dagens merino-sau. Altså handler dette om hvordan avl og kolonialisme og ikke minst industrielt landbruk har skapt store problemer.

Det er også mange andre ting som kan fenge spesielt interesserte, så katalogen eller boken er rikholdig og rikt illustrert og levert. Noe er litt tungt å lese, litt vel akademisk; men skitt au. Det tåler vi.

Laundry Care Regimes: Do the Practices of Keeping Clothes Clean Have Different Environmental Impacts Based on the Fibre Content?

Kirsi Laitala, Ingun Grimstad Klepp, Roy Kettlewell & Stephen Wiedemann

Abstract

Clothing maintenance is necessary for keeping clothing and textiles functional and socially acceptable, but it has environmental consequences due to the use of energy, water and chemicals. This article discusses whether clothes made of different materials are cleaned in different ways and have different environmental impacts. It fills a knowledge gap needed in environmental assessments that evaluate the impacts based on the function of a garment by giving detailed information on the use phase. The article is based on a quantitative wardrobe survey and qualitative laundry diary data from China, Germany, Japan, the UK and the USA.

The largest potential for environmental improvement exists in reducing laundering frequency and in the selection of washing and drying processes, and through a transition to fibres that are washed less frequently, such as wool. Adopting best practice garment care would give larger benefits in countries like the US where the consumption values were the highest, mainly due to extensive use of clothes dryers and less efficient washing machines combined with frequent cleaning. These variations should be considered in environmenta assessments of clothing and when forming sustainability policies. The results indicate the benefits of focusing future environmental work on consumer habits and culture and not only technologies.

Clothing Lifespans: What Should Be Measured and How

Ingun Grimstad Klepp, Kirsi Laitala & Stephen Wiedemann

Abstract

Increasing the use of each product, most often called longer lifespans, is an effective environmental strategy. This article discusses how garment lifespans can be described in order to be measured and compared. It answers two sub-questions: (1) what to measure (units), and (2) how to measure (methods). We introduce and define terms related to clothing lifespans and contribute to discussions about an appropriate functional unit for garments in life cycle assessments (LCA) and other environmental accounting tools. We use a global wardrobe survey to exemplify the units and methods.

Clothing lifespans can be described and measured in years, the number of wears, cleaning cycles, and users. All have an independent value that show different and central aspects of clothing lifespans. A functional unit for LCAs should emphasise both the number of wears for all users as well as the service lifespan in years. Number of wears is the best measure for regular clothing, while number of years is most suited for occasion wear, because it is important to account for the need of more garments to cover all the relevant occasions during a specified time period. It is possible to study lifespan via carefully constructed surveys, providing key data relating to actual garment use.

Dressing a Demanding Body to Fit In: Clean and Decent with Ostomy or Chronic Skin Disease

Kirsi Laitala and Ingun Grimstad Klepp

Abstract

This article discusses what kind of strategies people with a stoma or various chronic skin conditions, such as psoriasis oratopic dermatitis, use to find clothes that fit and enable them to fit in. Based on qualitative interviews in Norway, we study how they manage to dress with a demanding body, a poor market and limited economic resources. This includes describing how purchases take place, which clothes fit, how much clothing is needed, and which laundry practices are used. Their main strategy was to reduce the requirements for their own appearance rather than to cleanliness and body odours. If they were unable to appear appropriately dressed, as a minimum odourless and stain-free, they reduced their participation in social life.

Microfibres from apparel and home textiles: Prospects for including microplastics in environmental sustainability assessment

Beverly Henry, Kirsi Laitala & Ingun Grimstad Klepp

Abstract

Textiles release fibres to the environment during production, use, and at end-of-life disposal. Approximately two-thirds of all textile items are now synthetic, dominated by petroleum-based organic polymers such as polyester,polyamide and acrylic. Plastic microfibres (b5 mm) and nanofibres (b100 nm) have been identified in ecosystems in all regions of the globe and have been estimated to comprise up to 35% of primary microplastics in marine environments, a major proportion of microplastics on coastal shorelines and to persist for decades in soils treated with sludge from waste water treatment plants.

In this paper we present a critical review of factors affecting the release from fabrics of microfibres, and of the risks for impacts on ecological systems and potentially on human health. This review is used as a basis for exploring the potential to include a metric for microplastic pollution in tools that have been developed to quantify the environmental performance of apparel and home textiles. We conclude that the simple metric of mass or number of microfibres released combined with data on their persistence in the environment, could provide a useful interim mid-point indicator in sustainability assessment tools to support monitoring and mitigation strategies for microplastic pollution. Identified priority research areas include: (1) Standardised analytical methods for textile microfibres and nanofibres; (2) Ecotoxicological studies using environmentally realistic concentrations; (3) Studies tracking the fate of microplastics in complex food webs; and (4) Refined indicators for microfibre impacts in apparel and home textile sustainability assessment tools.

Use phase of apparel: A Literature review for Life Cycle Assessment with focus on wool.

Kirsi Laitala, Ingun Grimstad Klepp & Beverley Henry

Summary

This report presents a literature review of clothing use phase. The purpose is to support improved methodological development for accounting for the use phase in Life Cycle Assessment (LCA) of apparel. All relevant textile fibres are included in the review. However, the main focus is on wool. We ask whether the use of wool has different environmental impacts than clothes in other fibres. The report builds on a review of literature from the past 20 years. The review showed that clothing made from different materials are used, and reused in different ways. Wool is washed differently as it has about ten degrees lower washing temperature than the average laundry in Europe. Wool is also more likely to be either dry-cleaned or washed by hand than other textiles. Moreover, when dried, it is less likely to be tumble-dried.

When comparing the number of days between the washes of different types of clothes, we found that respondents were likely to use their woollen products about twice as long between washes compared to their equivalent cotton products. We also found that woollen products had a longer average lifespan and were more likely to be reused or recycled. There is a lot of research-based information available concerning the use and re-use of clothing, and we believe there are sufficient results available on which to base LCA studies. Furthermore, we believe that environmental tools that compare different fibres but exclude use phase provide misleading results. Including the use phase in fibre ranking benchmark tools will improve the rigour and accuracy of these tools for all fibres, compared to reporting results for fibre production only. However, we have also shown that there are several methodological, conceptual and empirical knowledge gaps in existing literature.

Global laundering practices: Alternatives to machine washing

Kirsi Laitala, Ingun Grimstad Klepp & Beverly Henry

Abstract

This article discusses laundering practices around the world including alternative methods such as washing by hand, airing, steaming, and dry-cleaning. These methods, which have received little attention in research, are often more suited toproducts made of wool, silk or other materials able to be cleaned using gentler techniques than more commonly used fibers such as cotton and synthetics. The material is based on extensive literature review from the past 20 years and reanalysis of previously unpublished survey data.The results show that washing by hand is common and that is the main laundering method in most rural areas of developing countries, but also significant for smaller portion of laundry in developed countries. Dry cleaning is less common, and mainly used for specific clothing items. Simple method such as airing can reduce the washing frequency, and thus reduce the environmental impacts resulting from the cleaning of clothes.

Sustainable clothing design: use matters

Kirsi Laitala and Casper Boks

Abstract

Many life cycle assessment studies document that the use period is the most resource-demanding phase during the clothing life cycle. In this paper, we discuss how design can help to reduce the environmental impacts of clothing. Motives behind clothing disposal, acquisition practices and maintenance habits are analysed based on two surveys, qualitative interviews of households, and examination of disposed clothing. The main reasons for clothing disposal were changes in garments, followed by size and fit issues, taste-related unsuitability, situational reasons, functional shortcomings and fashion or style changes. Several design solutions can enable the users to keep and use the clothes longer, and reduce the need for laundering, thus potentially decreasing the total environmental effects of clothing consumption.

Potential for environmental improvements in laundering

Kirsi Laitala, Casper Boks & Ingun Grimstad Klepp

Sammendrag

Life cycle assessment studies on clothes, detergents and washing machines show that the use period is usually the most energy-demanding period during these products’ life cycle, even higher than production or transportation phases. Laundering practices are constantly changing and influenced by social, cultural and moral norms. Even though the technologies in clothes cleaning have improved greatly, the length of time that consumers use for washing clothes has not been reduced. We own more clothing and wash it more frequently. This increased amount of washing counteracts the technological improvements in laundry.

This paper discussed the options of changing consumer habits in clothing maintenance to a more environmentally friendly direction and attempts to evaluate which changes would be the most feasible and efficient. Laboratory trial results on washing were compared with earlier research on consumers’ washing habits. Laboratory-based tests measuring cleaning effect, energy and water consumption were performed in order to evaluate the consequences of changing the washing temperature, filling grade, detergent dosage or drying method. The cleaning effect tests showed that today’s detergents are suitable for low temperature washing, and by selecting an efficient detergent, the cleaning result can be better at 30°C than with a less efficient detergent at 40°C. When washing only slightly soiled textiles or small loads of laundry, the detergent amount can be reduced. Many textiles changed more in colour or strength if they were washed at higher temperature(60°C) than at lower temperature (40°C or below). Tumble-dried textiles shrank more than line dried. These facts can be used to motivate consumers to change behaviour in order to reduce the environmental impacts of textile maintenance.
