  Abstract

The objective of this study was to determine effects of relative humidity on electrical heating textile properties. Relative humidity (RH) is a factor to determine clothing comfort. Electrical heating textile is used in close contact with human skin in winter or under extreme environments. Graphene/polymer composite was coated with flame retardant cotton fabric with a horseshoe-pattern. The relative humidity was controlled through water-sulfuric acid method. Samples were stored in external environment with different RH (25-% RH, 35-% RH, 45-% RH, 55-% RH, 65-% RH, and 90-% RH). With increasing RH, weight change rate also tended to increase due to increase amount of moisture absorbed by cotton fabric. Regarding surface resistivity under dry and each RH condition, it was found that surface resistivity change rate tended to decrease from 25 % RH to 55 % RH and then started increasing upto 90 % RH. Surface temperature and current of samples with various RH conditions were linearly increased with increasing applied voltage. When a voltage between 5 V and 6 V was applied to samples with various RH conditions, surface temperature was about 50 oC. Differences in surface temperature and current change rate tended to increase from under 25 % RH to 55 % RH conditions. However, they started decreasing from 65 % RH condition and the decline continued upto 90 % RH condition. These results confirmed that 55 % RH condition could improve electrical and electrical heating properties of samples. This condition could be expected to improve electrical properties of electrical heating textiles for wearable electronic applications.
