Odor Intensity in Apparel Fabrics and the Link with Bacterial Populations:

Odor Intensity in Apparel Fabrics and the Link with Bacterial Populations: 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Textile Research Journal SAGE

Abstract

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.
