The use and disposal phase in a garment's life cycle is highly dependent on the choices made by the consumer. Maintenance procedures such as laundering and drying require energy and water use. Garment disposal increases waste in landfill sites, unless incinerated, which can take a toll on the environment through greenhouse gas emissions. Therefore, encouraging consumers to launder less frequently and finding ways to extend the useful life of clothing are two ways of increasing sustainability within the clothing industry. Denim jeans are one of the most popular items of clothing worldwide. Changing habits such as reducing the frequency with which a person washes their denim jeans could have a positive impact on the environment through less water and energy use. However, environmental knowledge about what is detrimental to the environment may not necessarily lead to pro‐environmental behaviour. In denim jeans fibre loss results in thinning and loss in colour due to use. Laundering in particular can degrade clothing due to the abrasive forces applied to the surface of wet fibres. Therefore, this study highlights the effect that frequent laundering can have on the degradation of jeans with the aim to provide additional motivation to encourage change in consumers’ laundering habits. Consumers wore jeans for the equivalent of 60 days and either washed their jeans after approximately 2 days of wear or after approximately every 20 days of wear. The findings confirmed that frequent laundering reduced mass, increased colour loss, and reduced tensile strength in the warp direction of the fabric. Although washing is a major contributor to the degradation of jeans, the process of wearing denim jeans also naturally degrades the denim as the thigh region of the jeans showed greater colour loss and reduction in tensile strength than the shin region, which is typically less prone to abrasion through wear. The findings from this study provide compelling evidence to encourage consumers to reconsider their laundering habits in terms of wash frequency as both a means to behave in a more environmentally sustainable way, and to preserve their favourite garments.
The authors examined time spent on paid and unpaid work across the life course and historically to reflect on connections between activity patterns and macroeconomic events. The authors conducted quasi-cohort analysis on timeuse data over 30 years to examine trends in paid and unpaid work. Women aged 40 years and older spent more time on paid work and less time on unpaid work between 1971 and 1998. Men's paid work time decreased between 1971 and 1981 and between 1992 and 1998 but increased between 1981 and 1992, paralleling economic cycles. Paid work declined in later life, both in cross-sections and within birth cohorts, for men and women, and it declined more rapidly with each successive survey year. Unpaid work peaked around the usual retirement age for men and women in all birth cohorts. Retired seniors remained engaged in productive activities into later life, making a partial substitution of one form of productive engagement for another.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
