Comfort and Quality
Published in Motoyuki Akamatsu, Handbook of Automotive Human Factors, 2019
The breathability of fabric is influenced by yarn density, yarn thickness, yarn twist count, and material thickness. A complex interaction among these factors determines a material’s breathability. In addition, a backing material, which structurally fortifies a fabric material from behind, also affects breathability. Backing materials used to reinforce moquette fabrics are membranous and are hardly breathable. Accordingly, their use requires caution. Technologies to maintaining the breathability of a fabric material have been proposed.
Creative exploration: zero-waste fashion design practices with traditional Korean clothing

Go (袴) used natural fabrics with natural dyeing. Various fabrics were used, including linen, cotton, hemp and pongee, which are well-ventilated, and various cottons including calico, quilted cotton or silk were used for breathability and warmth depending on the season. Vegetable dyeing was the most common method in this era (Soh, 2013, p. 36); white, symbolising ‘purity’, was often worn, as well as so (素)-colour, the range of colours from pale off-white to beige of raw materials used for clothing. Silk and cotton could be bleached pure white naturally through repeated washing and sun drying (p. 43). Naturally derived materials and dyeing methods have zero-waste aspects, reducing waste sent to a landfill via biodegradation without leaving any municipal solid waste (MSW) during or after manufacturing.
Nanotechnology in textile and apparel research – an overview of technologies and processes

Beyond the ability to filter potentially inhalable particles, one of the most cited functions of nanofibers in clothing applications is in waterproof breathable fabric systems. Indeed, numerous researchers (Ahn, Park, & Chung, 2011; Bagherzadeh et al., 2012; Gu et al., 2018; Kang, Park, Kim, & Kang, 2007; Sheng et al., 2016; Sumin et al., 2009; Yoon & Lee, 2011) have explored the potential of nanofiber structures as an alternative to microporous thermo-mechanically expanded Polytetrafluoroethylene (PTFE) membranes, which have been the staple in the industry for several decades (patent by Gore-Tex). In those applications aimed at protective garments and outdoor wear, breathability (i.e. the ability to transfer moisture vapor) is a key performance feature for the thermo-physiological comfort of the body (ASTM, 2013; Das, Das, Kothari, Fanguiero, & Araujo, 2007; Hale, Dohrer, Tant, & Sand, 2001).

The water vapour transmission rate (WVTR) of the samples was measured in order to determine their breathability. It was carried out according to ASTM E96. A dish with inner diameter of 96 mm was filled with distilled water up to a distance of 20 mm from the fabric level. The sample was then placed on the dish with two rubber washers beneath and above it. The ring lid of the dish was then fastened using screws. The assembly was kept at laboratory conditions for 24 h and then weighed to calculate the mass of evaporated water. Three specimens were tested from each sample and the average WVTR values were calculated using Equation (2) and measured in g/m2/day. where G is the loss in mass (g) of the dish assembly over time; t, the time of the test (in hours), and A, the area of specimen exposed.
