Washing Clothes

  • by

Clothes must not only suit the user and the occasion but also be clean for us to be well dressed. The meaning of cleanliness and the methods to achieve this goal has changed throughout history, but it has been central in our clothing practices. In this chapter, we will show how the understanding of dirty and clean clothes and the work of keeping them clean has changed in the last 200 years.

Textile Cleaning and Odour Removal

  • by

Consumers’ textile care practices today are characterized by frequent laundering. The importance of the removal of odours has increased, especially the smell of sweat. This chapter summarizes knowledge about removing odour from textiles.

The Consumer Perception of Odour

Human olfaction sense is one of the highly underestimated senses since historical times. Fortunately, this has changed in recent times, as the perception of odour or scent by people has received increasing attention through several research works from different scientific disciplines.

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

  • by

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.

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

  • by

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.

  • by

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

  • by

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.

What’s the Problem? Odor-control and the Smell of Sweat in Sportswear

  • by

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.

Patched, Louse-ridden, Tattered: Clean and Dirty Clothes

“Patched, louse-ridden, tattered—clean, beautiful, gem.” As children we recited this rhyme in Norwegian: “Lappete, lusete, fillete—ren, pen, edelsten,” as we picked petal after petal from a daisy. All the words can be understood as descriptions of the child’s future clothes. Clean is the turning point in the rhyme. Clean is thus seen as the first step on the way towards the gem, and it conveys here the same meaning as in the saying “whole and clean is the greatest finery.” Both emphasize clean clothes as crucial to the judgment of a person’s appearance. In the world of fashion it has been alleged that “anything goes.” This is probably true if we restrict “anything” to small variations in the look, decor, color, and style of clothes. However, our way of dressing also depends on more absolute norms.

This article explores the norms that deal with the relationship between clean and dirty clothes. Despite the fact that there is abundant research on cleanliness and laundering on the one hand, and clothes and clothes habits on the other, there are few points of intersection between the two fields. The article is an attempt at seeing these two themes in conjunction. It investigates how clothes, by being kept clean, make bodies socially acceptable. The article looks at how the demand for cleanliness varies in relation to age, gender, and class, and compares these demands to what we know about decency.
