WebMar 23, 2007 · Ionic liquids containing imidazolium cations have been extensively studied, and have found applications in catalysis [ 1], analytical chemistry [ 2], and elsewhere [ 3].The development of functionalized (or task-specific) ionic liquids received much attention due to the potential to impart the liquid with specific chemical and/or physical properties [3, 4]. WebCellulose and m-aramid were dissolved in an ionic liquid, and dry-jet wet spinning was employed to prepare composite fibers which could be rendered antimicrobial through exposure to chlorine bleach. The small domains of the m-aramid allowed a much higher accessibility and degree of chlorination than has been reported even for 100% m-aramid …
WebIn a process for improving the dye affinity of aromatic polyamides with NH3, aramid fibres are treated in liquid NH3 and then dyed with basic dye. Treatment in liquid NH3 is carried out for 3 s to 10 min at -40 to -33 deg C and atmos. pressure. After padding, the NH3 is removed by steaming or rinsing.
