Dyeing Properties of m-Aramid Fibers Using $PEO_{45}$-MeDMA

$PEO_{45}$-MeDMA를 이용한 m-aramid 섬유의 염색특성

A diblock copolymer($PEO_{45}$-MeDMA) derived from [2-(methacryloyloxy) ethyl] trimethylammonium chloride(MeDMA) was synthesized and applied to the meta-aramid fibers. Meta-aramid fabric was pretreated with $PEO_{45}$-MeDMA and successfully dyed with acid dyes. The dyeability of this fabric was investigated and found to depend on the $PEO_{45}$-MeDMA concentration, pH, and dye concentration. The color fastness properties of the copolymer pretreated dyed fabric was evaluated.
