As the global environment changes, the development of thermal functionality of fabric products has attracting attention. Accordingly, methods to measure the surface temperature of fabrics and an experimental system to immediately provide changes in humidity for this purpose were examined. We first attempted a method to move the humidity setting of an artificial climate chamber up and down at the maximum rate for the evaluation of exothermicity of moisture absorption and endothermicity of moisture release characteristics. Next, we evaluated a method to move back and forth between two consecutive climate artificial chambers to measure exothermicity of moisture absorption and endothermicity of moisture properties with higher accuracy. The latter method was then used to compare the infrared thermocamera, a non-contact thermometer, with the K-type thermocouple sensor, a contact thermometer.

DNA ion complexes of anionic DNA and two forms of cationic surfactants with a sixteen-carbon alkyl chain in their tails were utilized to prepare their films using a hot-press molding. The surfactants were hexadecyl pyridinium chloride (HDPyCl) and hexadecyltrimethylammonium bromide (HDTMABr), which had different polar head groups of pyridinium and trimethylammonium cations, respectively. The ion complex powders of DNA-HDPy (D-HPy) or DNA-HDTMA (D-HTm) were converted to their free-standing films with the hot-press treatment. Both bulk structures were investigated and compared using small angle X-ray scattering (SAXS), a gas pycnometer, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), and a tensile test. Further, antibacterial activities against Staphylococcus aureus of the films were also evaluated since the surfactants are known to possess inhibition of microbial growth.
