Design for Extended Clothing Lifecycles: Integrating Social and Technical Durability

Designing clothing with enhanced social and technical durability can significantly extend its usable life, thereby reducing the environmental impact of the use phase.

Research Repository (Delft University of Technology) · 2010

Key Findings

01The use phase of clothing is the most resource-intensive period in its lifecycle.
02Social factors, such as the fear of stigma from re-wearing clothes or concerns about body odor, significantly influence laundering frequency and thus environmental impact.
03Technical durability, combined with designs that address social concerns, can lead to longer use periods and broader applicability of garments.

Application

Design takeaway

How to apply

When designing apparel, consider materials and construction techniques that enhance physical durability and incorporate features or provide information that addresses social concerns like odor and the perception of re-wearing.

Project actions

01When researching user needs, explore not just functional requirements but also social and psychological factors influencing product use and disposal.
02Consider the entire lifecycle of your design, paying particular attention to the 'use' phase and how design choices can impact resource consumption during this period.

Method & Evidence

AimHow can clothing design be optimized to promote sustainable use by addressing both the social and technical aspects of durability throughout the product's lifecycle?

MethodMixed-methods research combining quantitative consumer surveys with qualitative interviews and laboratory analysis of disposed garments.

ProcedureResearchers conducted surveys and interviews to understand consumer motivations for clothing disposal, acquisition, and maintenance. They then collected and analyzed garments slated for disposal in a textile laboratory to assess technical durability and gather insights into social factors influencing garment longevity.

SampleStrategic selection of households (specific number not stated in abstract).

ContextApparel and textile design, consumer behavior, sustainable product development.

Variables

IV["Design features promoting social durability (e.g., odor resistance, versatile styling)","Design features promoting technical durability (e.g., material strength, construction quality)"]

DV["Frequency of garment use","Duration of garment ownership","Frequency of laundering","Consumer perception of garment longevity and desirability"]

CV["Socioeconomic background of participants","Climate/environmental conditions","Washing machine technology available"]

Strengths & Limitations

Strengths

+Combines multiple research methods for a comprehensive understanding.
+Addresses a critical but often overlooked aspect of product lifecycle: the use phase.

Limitations

The study's focus on specific consumer groups might limit the universality of its findings. The methods used to assess 'social durability' are inherently subjective and difficult to quantify precisely.

Reliability & validity

The study's validity is strengthened by its mixed-methods approach, combining objective lab analysis with subjective user feedback. Reliability could be enhanced by replicating the consumer survey across diverse demographics and geographical locations.

Think critically

To what extent can designers truly influence consumer behavior regarding clothing use, and what are the ethical implications of designing to 'make undesirable behavior impossible'?

Design Principles

"Design for extended use by addressing both functional longevity and social acceptance of repeated wear and reduced maintenance."

The use phase of clothing is a major contributor to its environmental footprint. By considering factors beyond material performance, such as social acceptance of re-wear and resistance to odor, designers can create products that consumers will use for longer periods and with less frequent, resource-intensive maintenance.

What This Means for Your Design

To make clothes more eco-friendly, designers should think about how people feel about wearing the same clothes multiple times and how to keep them smelling fresh, not just how strong the fabric is.

How to use in your project

1.Use this research to justify design decisions aimed at extending product lifespan, particularly in the context of sustainable design or user-centered design challenges.

Paragraph starter

This research highlights that the environmental impact of clothing is heavily influenced by its use phase, which is often extended by designing for both technical durability and social acceptance. By addressing consumer concerns such as odor and the perception of re-wearing, designers can create garments that are used for longer periods, thereby reducing the need for frequent replacement and associated resource consumption.
