Abstract

Sport and fitness are increasing in popularity, and so is awareness of body odor. Both are aspects people wish to gain control over, as promised by the marketing of sportswear with odor-controlling properties. This article discusses how the heightened awareness of body odor has developed, and how unpleasant odor varies between textiles made of different materials. A sensory analysis by a consumer panel was used to evaluate the odor intensity of 13 different fabric samples taken mainly from sportswear.

The so-called odor-control textiles smelled less intense than similar polyester samples without such treatment. Wool and cotton smelled significantly less intense than both odor-control and polyester when the samples were sweaty or aired. After washing, the odor-control textiles had a level of odor intensity that was in between that of the cotton and woolen samples. The odor-control treatment reduced the smell, but not enough to make a difference on laundering frequency, and the textiles smelled still more strongly than wool.

Hjemmeproduksjon og gamle klær i velstands Norge» av Ingun Klepp og Kirsi Laitala inngår i et større prosjekt om grønn vekst gjennom kunnskap om bærekraftige klær i lokale verdikjeder med fokus på utnyttelse av norsk ull (KRUS). Studien viser at bruk av ull er utbredt i hele befolkningen. Det er imidlertid klare kjønns- og inntektsforskjeller i befolkningens forhold til ull. Kvinner kjøper og bruker ullplagg oftere enn menn. Noe under halvparten (43%) av kvinnene har selv strikket eller laget plagg og andre produkter av ull i siste året. Kun 4 prosent av mennene oppga det samme. Det er også en større andel av kvinner som har bunad enn menn. Superundertøy (syntetisk) er imidlertid mer populært for menn enn kvinner (hhv 78% og 67%). Respondenter med høy inntekt eier flere dyre ullplagg enn respondenter med lavere inntekt. Det er også slik at ullklær brukes lengre enn andre typer klær og mange av de eldste plaggene som fortsatt er i bruk er av ull. Interessen for hjemmeproduksjon og strikking er stigende i den norske befolkningen, spesielt blant yngre kvinner. Artikkelen konkluderer med at for å få en omlegging henimot bærekraftig klesforbruk er det viktig å fokusere på lang levetid, hjemmeproduksjon og verdier – både pekuniære og affektive – knyttet til klær.

Wool as an Heirloom: How Natural Fibres Can Reinvent Value in Terms of Money, Life-Span and Love

ingridha on 24. august 2016

Ingun Grimstad Klepp, Tone Skårdal Tobiasson & Kirsi Laitala

Abstract

This paper addresses a main challenge for natural fibres; falling prices and increased focus on quantity versus quality. This is a challenge not only related to economic issues and profit, but is also unsustainable in an environmental perspective and in light of the challenges the textile sector and the world face. The paper uses wool as an example and in a surprising approach links the history and century-old traditions of natural fibers to an environmental thinking which supplements the traditional thinking around circular economy and LCA. Fabrics with a long life are the ones that have the lowest environmental impact (Fletcher and Tham2015; Laitala2014). Longevity or lifespan is a complex phenomenon in which both technical and social, or aesthetic aspects, are intertwined.

Why Cotton as Linen? The Use of Wool in Beds in Norway

ingridha on 22. august 2016

Ingun Grimstad Klepp, Tone Skårdal Tobiasson & Kirsi Laitala

Abstract

Cotton is the “natural” choice and the dominating material in bed linen and sleepwear in Norway as in many other European countries. Regulation of temperature and humidity are important for good sleep, but they are not cotton’s strong points. There must have been other than the functional reasons which made cotton the winner in the bedding market. This article builds on literature about bedding in Norway from the 1800s and survey questions from 1951. We ask the question: what materials have been used and why? Wool was used in all bed textiles, both closest to the body and the layers over and under, from the cheapest chopped rags to the most costly textiles. The decline was seen throughout the 1800 and 1900s, but only in the 1960s does wool become totally absent as a next to skin bed textile. The cheap imports of cotton made cottage industry and home production unprofitable and the new emphasis on cleanliness gave cotton a clear leverage.

Sammendrag


Vi har undersøkt mulighetene for å gjeninnføre ull som sengetekstil. Barrierer for bruk av ull i nattøy og sengetøy blant norske og svenske forbrukere er analysert basert på web survey, intervjuer der informantene også kjente på en rekke ulike stoffer, og en brukertest av sengetøy og nattøy i ull. Muligheten for et sengetøy i ull ble møtt med positiv nysgjerrighet av de aller fleste informanter. Et viktig funn er koblet til hvordan endring finner sted. I Norge er bruken av ull, og da spesielt på mindre barn og i forbindelse med utendørsaktiviteter om vinteren en norm, en standard forbrukeren bevisst må velge bort. I Sverige derimot er valget av ull, nettopp et valg noen gjør og da ofte med en sterkere ideologisk begrunnelse. Markedet for kroppsnær ull vokser i Sverige og forskjellene mellom de to land kan dermed forventes å minke. Barrierer knyttet til hygiene, varmeregulering, struktur og mykhet er viktige i forbrukernes tanker omkring ull som sengetekstil. De har lite erfaringer med tynnere vevde stoffer og vanskeligere for både å gjenkjenne slike stoffer som ull og se for seg hvordan de vil virke i bruk.

Klærs levetid – LCA på liv og død

ingridha on 24. januar 2016

Ingun Grimstad Klepp & Kirsi Laitala

Innledning

Et av de mest fremtredende trekkene ved de siste 50 års tekstilforbruk er veksten i mengde. Import av klær har økt med 67 % i de siste tjue årene, og ligger nå på 15 kg per innbygger i Norge (SSB, 2014). Vi vet lite om denne veksten, men at den henger sammen med en nedgang i priser og en oppgang i kjøpekraft, er åpenbar. I samme periode har andelen av husholdningenes forbruk av klær og sko falt fra 6,6 % til 5,4 % av utgiftene (SSB, 1999, 2013). Til tross for denne nedgangen har klesforbruket målt i volum økt. Dette har ikke skjedd uten miljøkonsekvenser. Carbon trust (2011) har estimert at 3 % av globale klimautslipp, målt i CO2-ekvivalenter, stammer fra produksjon og vask av klær. I tillegg kommer utslipp av skadelige kjemikalier, uetiske arbeidsforhold, problemer med dyrevelferd, og høyt forbruk av energi, vann og land-arealer (Fletcher, 2008).

Livsløpsanalyser (LCA) blir brukt for å skaffe informasjon om de totale miljøpåvirkningene av et produkt eller en aktivitet. LCA-studiene brukes blant annet som grunnlag for ulike typer verktøy som gir råd til bedrifter, designere og forbrukere om hvordan de kan produsere og handle mer miljøriktig (for oversikt over slike verktøy, se f.eks. Klepp et al., 2015; Kviseth, 2011). Et viktig element i disse verktøyene er at de rangerer ulike fibre mot hverandre. Dette kan få store konsekvenser fordi det brukes som grunnlag for beslutninger om hva klær og andre tekstiler produseres av. Mange bedrifter, designere og forbrukere ønsker jo å ha «miljøriktige» klær, som lett forstås som klær i bestemte materialer. Den store vinneren har så langt vært resirkulert polyester. I dette kapitlet diskuterer vi hvorfor de LCA-studiene verktøyene bygger på er lite relevante, og hvorfor de dermed kan få store miljømessige konsekvenser.

Summary

This report aims to chart a plan for a coordinated Nordic effort towards sustainable development in textiles and identify ongoing initiatives in the area. The aim was an ambitious plan with a potential for significant reductions in environmental pressures, but also green growth. To reach these goals, we staked out four regions a Nordic plan should include.

  1. Replace fast fashion
    The key to achieving an environmentally significant effect is to
    reduce the amount of textiles in circulation. This will reduce the
    production of waste and the use of chemicals.
  2. Reduce resource input
    The perspective is all about reducing inputs in textiles value chain. This includes various forms of circulatory thinking, material efficiency, as well as commercial forms of recycling and waste management.
  3. Redirect global vs local
    Locally produced textiles, with emphasis on ingredients, traditions, uniqueness and innovation, is a new and positive measure that can easily get attention outside environmentally conscious circles. A greater appreciation for good ingredients, and why quality costs, are required to compete with “fast fashion” and shift towards lasting value. Local production has the potential to create green growth and jobs in the region.
  4. Rethink for whom
    Nordic countries are at their best an example of inclusive and
    democratic societies. The fashion industry however, has marketed itself towards the young and thin. An ethical approach to fashion encompasses not only how clothing is produced, but also who they are produced for and how clothing affects the ability for selfexpression and participation in an open society.
Ongoing initiatives

The mapping showed that there were many ongoing initiatives in the Nordic. The work has mainly focused on the perspective of so-called “reducing resource use”. The more established an initiative is, the more likely it is to be low on innovation. An important dilemma surfaces when attention is on better utilization of waste, as this may indirectly contribute to increased growth in volume.

Knowledge and further research

We lack most knowledge in areas with the greatest opportunity for reduction in environmental impact. The knowledge follows an inverted waste pyramid, where prevention, longevity, etc. are very important, but with a low knowledge-level. Another important distinction is between the market understood as an exchange of money and what goes on outside these formal markets, and there is in general little knowledge about the latter parts of the value chain. The report contains a list of knowledge gaps and suggestions for further research.

Nordic positions of strength
  • Consumers have little knowledge about textiles in general and the products do not contain information about basic characteristics (durability, quality, etc.) enabling them to make informed choices.
  • The Nordic region’s main strength is an ease of dressing for movement and the outdoor elements.
  • Handicraft traditions are strong, however they may be disappearing.
  • There is some renewal of interest in more local sourcing.
  • Reuse and recycling are the main focus, in spite of lack of a recycling industry and limited market.
  • High standing as ethically and environmentally concerned region.
  • Tradition of cooperating in spite of language and cultural differences.
  • Social networks and electronic tools could be used even more.
  • Inclusion, democracy and participation are important values.
  • There is a lack of common statistics on the sector.
Policy and regulation

The textile industry is international with few global policy regulations. There is a great opportunity for the Nordic region to make a difference.

Suggestions for a Nordic roadmap
  • Avoid symbolic issues and cases, and focus on making a substantial difference environmentally.
  • Contribute to a discussion of the relationship between the global and the local in textiles.
  • Collectively engage the sector in thinking positive and offensively, being inspiring and visionary.
  • The roadmap must work with the whole sector, not just the commercial industry.
  • Engage all the Nordic countries and exploit the strength in our differences.
  • Ensure knowledge exchange through building on the current state of know-how and the enthusiasm nationally and internationally.
  • Acquiring new knowledge where there are obvious blind spots.
  • Set specific, ambitious, and achievable (political) goals.
  • Support the public debate on central themes.

Making Clothing Last: A Design Approach for Reducing the Environmental Impacts

ingridha on 31. august 2015

Kirsi Laitala, Casper Boks & Ingun Grimstad Klepp

Abstract

This article discusses the extent it is possible to delay clothing disposal through improved design, thus reducing negative environmental impacts. This has been done by including user centered design methods into more traditional quantitative consumer research to give new insights for design. Empirical data on reasons for disposal of 620 clothing items from 35 persons in 16 Norwegian households was collected. In total, 70 different disposal reasons were registered, which were combined into seven main categories.

Changes in garments as well as size and fit issues dominated, while functional, situational, taste, and fashion related reasons were less common. The article concludes with design solutions on four levels related to the important disposal reasons including product design (material and shape), service design, and systems design, but also shows that consumer behaviour is crucial. In addition, the combination of results obtained with various qualitative and quantitative methods proved to be suitable for giving rich data that can be used to drive design research forward.

Clothing disposal habits and consequences for life cycle assessment (LCA)

ingridha on 24. august 2015

Kirsi Laitala & Ingun Grimstad Klepp

Abstract

This chapter discusses the effects of end-of-life scenarios to the life cycle assessment (LCA) calculations. Consumers’ decisions in the disposal phase of clothing are crucial from an environmental point of view, as they affect the lifespan of clothing, as well as the potential for reuse and recycling. In doing this, examples of Norwegian consumers’ clothing use and disposal practices are used.

We will present statistics for the current situation in Norway as well as qualitative material on clothing disposal practices and discuss disposal methods and frequencies. Instead of assuming that all clothes are disposed of equally regardless of type of garment, person and place, the LCA analyses should be nuanced in relation to knowledge of disposal practices. Analysis also shows also that if improvements are made in facilitating reuse, clothing lifespans could easily be prolonged.
