Abstract

Several tools have been developed to compare the environmental impact of textiles. The most widely used are Higg Materials Sustainability Index (MSI) and MADE-BY Fiber Benchmark. They use data from production to evaluate the environmental impacts of textiles differentiated by fiber type. The use phase is excluded from both tools. This article discusses whether there is evidence that the use of textiles differs systematically between different fiber types and examines the consequences of comparing the environmental impacts of clothing based on differences in production of fibers alone without including differences in their use.

The empirical material in this paper is based on analysis of rating tools and a literature review on clothing use. It shows that fiber content contributes to the way consumers take care of and use their clothing. When use is omitted, major environmental problems associated with this stage, such as spread of microplastics, are also excluded. This one-sided focus on material production impacts also excludes the importance of product lifespans, quality, and functionality. The consequence is that short-lived disposable products are equated with durable products. Comparing dissimilar garments will not help consumers to make choices that will reduce the environmental burden of clothing. We need an informed discussion on how to use all materials in the most environmentally sustainable way possible.

Nisseluelandet—The Impact of Local Clothes for the Survival of a Textile Industry in Norway

ingridha on 22. June 2018

Ingun Grimstad Klepp & Kirsi Laitala

Abstract

The article discusses the importance of local clothing for the survival of the Norwegian textile industry. It draws upon stakeholder interviews, as well as desktop research. Local clothes are discussed as they are understood by consumers, as knitted sweaters, bunads (Norwegian national costumes), and home-made clothing. The review shows how these products, and especially the materials used in their production, have been crucial for the continued existence of the Norwegian textile industry. We argue that the concept “local clothes” can contribute to showcasing resources outside the global “fast fashion” manufacturing system.

Motivations for and against second-hand clothing acquisition

ingridha on 1. June 2018

Kirsi Laitala and Ingun Grimstad Klepp

Abstract

One of the possibilities consumers have for more sustainable clothing acquisition is to select pre-owned products. This article explores consumers’ motivations for clothing reuse: why they choose or do not choose to acquire second-hand clothing. First, a taxonomy of motivation categories based on previous studies is presented. This demonstrates that similar properties can be used as arguments both for and against acquisition of second-hand clothing. An analysis of a representative sample of Norwegian consumers shows that both environmental and economic reasons are important for those who take part in informal clothing circulation. Uniqueness and style are more important for those who buy second-hand clothing.

Those who do not take part in any of the forms of acquisition of used clothing, use vague and open justifications, as well as contextual aspects; hygiene, health and intimacy. Previous studies have mostly been based on how clothing is reused as part of a market exchange, and therefore the motives have been embedded with a rational choice understanding of consumption. Studies of the private exchange of clothing should also address additional reasons such as routinized practices and established rituals, family ties, feelings, friendship and love. The article concludes with an invitation for further research to explore several possible motivations that are more relevant for private circulation of clothes.

Shared use and owning of clothes: borrow, steal or inherit

ingridha on 26. May 2018

Ingun Grimstad Klepp and Kirsi Laitala

Abstract

This chapter takes a close look at the different forms of sharing based on empirical material on leisure clothing in Norwegian families. We ask what forms of sharing are practiced, which terms are used, and how consumers draw distinctions between them. We find that the forms are numerous and have an established place in Norwegian clothing culture. Sharing within the household, outside the pecuniary market, appears still to be the most important and also the most understudied form of sharing.

The literature about clothing consumption is increasingly about sharing, but limited to the new forms. However, sharing is a common form of human interaction, often misunderstood or overlooked. In order to understand the role of collaborative consumption in contemporary society, it is necessary to study both new and old forms of sharing. For a more systematic mapping of these forms a good place to start might be the study of relationships between access and ownership, and between different temporalities.

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

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 to products 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.

Clothing Reuse: The Potential in Informal Exchange

Kirsi Laitala and Ingun Grimstad Klepp

Abstract

Reuse organised by non-profit and commercial actors is a strategy that recently received a lot of attention. This article discusses the question: what do we know about the amount of clothes that circulate outside the pecuniary markets? And is this amount increasing or declining? The questions are answered based on quantitative material from Norway. Almost twice as many had received used clothing as those who had bought used clothing, and our material do not indicate that this are declining. At the same time 59 per cent of Norwegian adults had neither received nor bought used clothing for themselves during the past two years. For children, inheritance is very common and the younger the children are, the more they inherit. The amount of the private clothing exchange is greater than the formal market in Norway. Therefore, when the goal is a more sustainable clothing consumption we need to include the parts of consumption that are not only related to money.

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.

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.

Wool you wear it? – woollen garments in Norway and the United Kingdom

ingridha on 24. August 2016

Marie Hebrok, Ingun G. Klepp & Joanne Turney

Abstract

This article was developed from the project ‘Valuing Norwegian Wool’ initiated by the Norwegian National Institute for Consumer Research to generate knowledge on how wool can contribute to sustainable textile consumption, and how value creation can be increased in the Norwegian wool industry. The article will compare consumer perceptions, attitudes, practices and knowledge concerning wool as a material and as garments in Norway and in the United Kingdom, through a case study of wardrobes owned by six middle-class families.

The aim is to generate knowledge about the diverse web of aspects that influence consumption of woollen garments. The wardrobe study as a method aims to include the materiality of garments in clothes research in a more direct way. Analysing the materiality in connection with the social and cultural aspects of clothes gives us a better understanding of the relations between materiality and practice.
