Hemp Fibers

Liquid ammonia treatment can improve the properties of a hemp fiber and widen its application in textiles. This study investigated the effects of different ways of NH3 removal on the fine structure and properties of hemp fibers, including thermal property and dyeing behaviour. It was found that, of the three ways of ammonia removal, removal of ammonia with glacial acetic acid resulted in the highest transition of cellulose Ⅰinto cellulose Ⅲ and removal ammonia with water resulted in the lowest transition of cellulose Ⅰinto cellulose Ⅲ. Removal of ammonia with water also resulted in better thermal stability and higher dye uptake than the other ways of ammonia removal. Of the three ways of ammonia removal, removal of ammonia by evaporation resulted in the lowest dye uptake.

Effect Of Surface

Polyaniline-modified natural fibers have been recognized as promising candidates for conductive clothes, UV protection, and electromagnetic interference shielding. Hence, the purpose of this study was to investigate the effect of surface deposition of cotton fibers using polyaniline via in situ polymerization, and preceding structural changes were further screened by FT-IR, UV-Vis, TGA, SEM/EDX, and conductivity in comparison with bare cotton fibers used as the control sample. Polyaniline was introduced on the surface of cotton fibers as a conductive form, which was confirmed by electrical conductivity (1.54 × 10−4 Scm−1) equivalent to semiconductor materials. Detection of particular peaks at NKα 0.379 keV and ClKα 2.621 keV from EDX analysis revealed the introduction of nitrogen and chlorine, respectively. Polyaniline deposition on the cotton surface was successful to introduce hydrophobic environment to the system to enhance resistance to water absorption meaningfully.
