Troubles with the Solution: Fabric Softeners and Odour Properties

Abstract

Abstract Fabric softeners are mainly used to reduce roughness and static electricity of textiles, as well as adding a scent to them. In this paper we study how fabric softeners are related to odour properties on clothing. We combine a Norwegian consumer survey with a sensory test on odour development on four different materials used in sports clothing. Samples went through several cycles of use with sweating, washing, and airing and the odour was evaluated at 11 stages. Washing was performed either with or without a fragrance-free domestic rinse cycle softener. Sensory test showed that use of softener increased odour on polyester garments. Survey results showed that a larger number of respondents who used softeners experienced problematic odours in laundry compared to those who did not use softeners.
