Study on Clothing Damage and Deformation Caused by Dryer Use and Its Impact on User Satisfaction

This study explored types of damage and deformation in clothing caused by household dryer use and their impact on user satisfaction. A survey was conducted with 250 adults who use household dryers, examining their dryer usage patterns by clothing type. A factor analysis categorized clothing products into 'casual wear,' 'athleisure,' 'knitwear,' 'formal wear,' and 'bedding/down.' BR/ Results showed that men used dryers more frequently than women for 'athleisure' and 'formal wear.' Additionally, individuals in their 50s tended to use dryers for 'formal wear' more often than those in their 30s and 40s. The number of cohabiting family members was also found to be related to dryer use for 'bedding/down'. Among types of damage reported from dryer use, shrinkage was the most common issue, followed by fraying/weakening, shape deformation, and wrinkling/creasing. An analysis of the relationship between garment damage/deformation and satisfaction with dryer use revealed that fraying/weakening and odor generation significantly impacted satisfaction for towels. Shrinkage and lint/pilling affected satisfaction for cotton T-shirts, while for blouses, wrinkling was identified as a key factor influencing satisfaction. For jersey knits and sweaters, shrinkage was the most frequently reported type of damage, although it did not have a significant relationship with satisfaction. Instead, fraying/weakening was found to have a significant impact on satisfaction. This study analyzed types of damage caused by dryer use and confirmed that types of damage affecting satisfaction with dryer use could vary depending on the clothing type.
