Retention of Odorous Compounds by Textile Materials

  • Body odour consists of different compounds that interact in various ways with textile materials due to differences in their chemical properties. Clothing made from hydrophilic fibres (e.g., cotton) can be more easily laundered, and odorants more effectively removed than those made from hydrophobic fibres (e.g., polyester). Therefore, the purpose of this research was to examine the interactions between textile materials and odorous compounds when washed several times with different detergents. Test fabrics were of both interlock knit structure and either 100% cotton (234 g/m2) or 100% polyester (224 g/m2) fibre content. Test compounds were 4-ethyl octanoic acid (octanoic acid) and 2-nonenal (nonenal). Fabric samples were spiked with 10 µL of a solution of octanoic acid (0.1g), nonenal (0.1g) and dichloromethane (solvent) and left to sit for 24 hours. Inoculated samples were washed with either Tide® Free and Gentle detergent or Tide® Febreze Sports detergent. Residual odorants were measured using gas chromatography with flame ionization detector. Headspace analysis of volatiles was conducted using solid-phase micro-extraction (SPME); direct extraction of compounds remaining in fabrics was done using dichloromethane as the solvent. Considering the peak area of odorants, findings show that cotton generally retained and desorbed lesser odorous compounds than polyester did. Interestingly, the non-polar nonenal was difficult to remove from the non-polar hydrophobic polyester by washing, which resulted in higher quantities of nonenal compared with octanoic acid in the headspace. Also, while multiple washes eventually became more efficient in removing odorants from cotton, polyester did not clean as well.
