Nine apparel fabrics varying in fiber (cotton, wool, polyester) and knit structure (1 × 1 rib, interlock, single jersey) were investigated for their retention of axillary odor following wear. As axillary odor results from bacterial metabolism of apocrine and sebaceous secretions, counts of total aerobic bacteria and corynebacteria on the fabrics were carried out. Odor intensity was strongly associated with the fiber type, with polyester fabrics rating high in odor intensity and cotton and wool mid-low odor intensity. A structure effect was apparent for polyester fabrics, with the lightweight single jersey fabric rated less odorous than the heavier-weight interlock and 1 × 1 rib structures. The relationship between fiber type and odor was not influenced by bacterial numbers present, with counts after one day similar for all fabrics. However, the number of bacteria declined more rapidly on polyester fabrics than on either the cotton or wool fabrics. Counts of odor-associated corynebacteria subgroup (A) remained largely unchanged on wool fabrics for 28 days.

The accumulation of phthalate esters, brominated flame retardants (BFRs) and organophosphate esters (OPEs) by clothing from indoor air and transfer via laundering to outdoors were investigated. Over 30 days cotton and polyester fabrics accumulated 3475 and 1950 ng/dm(2) ∑5phthalates, 65 and 78 ng/dm(2) ∑10BFRs, and 1200 and 310 ng/dm(2) ∑8OPEs, respectively. Planar surface area concentrations of OPEs and low molecular weight phthalates were significantly greater in cotton than polyester and similar for BFRs and high molecular weight phthalates. This difference was significantly and inversely correlated with KOW, suggesting greater sorption of polar compounds to polar cotton. Chemical release from cotton and polyester to laundry water was >80% of aliphatic OPEs (log KOW < 4), < 50% of OPEs with an aromatic structure, 50-100% of low molecular weight phthalates (log KOW 4-6), and < detection-35% of higher molecular weight phthalates (log KOW > 8) and BFRs (log KOW > 6). These results support the hypothesis that clothing acts an efficient conveyer of soluble semivolatile organic compounds (SVOCs) from indoors to outdoors through accumulation from air and then release during laundering. Clothes drying could as well contribute to the release of chemicals emitted by electric dryers. The results also have implications for dermal exposure.

Uptake kinetics of semi-volatile organic compounds (SVOCs) present indoors, namely phthalates and halogenated flame retardants (HFRs), were characterized for cellulose-based cotton and rayon fabrics. Cotton and rayon showed similar accumulation of gas- and particle-phase SVOCs, when normalized to planar surface area. Accumulation was 3-10 times greater by rayon than cotton, when normalized to Brunauer-Emmett-Teller (BET) specific surface area which suggests that cotton could have a longer linear uptake phase than rayon. Linear uptake rates of eight consistently detected HFRs over 56 days of 0.35-0.92 m /day.dm planar surface area and mass transfer coefficients of 1.5-3.8 m/h were statistically similar for cotton and rayon and similar to those for uptake to passive air sampling media. These results suggest air-side controlled uptake and that, on average, 2 m of clothing typically worn by a person would sequester the equivalent of the chemical content in 100 m of air per day. Distribution coefficients between fabric and air (K') ranged from 6.5 to 7.7 (log K') and were within the range of partition coefficients measured for selected phthalates as reported in the literature. The distribution coefficients were similar for low molecular weight HFRs, and up to two orders of magnitude lower than the equilibrium partition coefficients estimated using the COSMO-RS model. Based on the COSMO-RS model, time to reach 95% of equilibrium for PBDEs between fabric and gas-phase compounds ranged from 0.1 to >10 years for low to high molecular weight HFRs.

Where clothing consumption has continued to rise around the world, a deeper understanding of how and why garments are disposed of is critical in regard to addressing the issue of textile waste by consumers. The purpose of this study was to explore the garment management processes of young, fashion sensitive consumers, examining their disposal behaviours as well as motivations towards garment end‐of‐life extension through maintenance or repair of damaged fashion clothing. A survey of 161 South Korean young consumers (18–34 years) was conducted, utilizing a fashion sensitivity scale to measure impact on unsustainable garment disposal practices and garment repair behaviour. Further, general recycling behaviour of these individuals was examined, as linked to garment repair propensity. Results indicate that fashion sensitive consumers dispose of garments more rapidly, and with less ethical consideration. However, these same consumers are motivated to repair items that support their fashion identity. The study contributes some useful insight into encouraging garment life extension practise among heavy consumers of fashion, thus extending what is known about fashion garment disposal in the sustainability context.
