摘要：
In order to solve the problem that aramid fiber is difficult to dye and print by conventional process, the aramid fabric was pretreated by ozone plasma and then modified by resin. The influence of plasma pretreatment on the surface elements and morphology of resin modified aramid fiber was studied, and the dyeing effect of modified aramid fabric with disperse dyes was explored. It was found that ozone plasma pretreatment introduced abundant active groups and constructed rough interface, which significantly improved the uniform dispersion of resin, and the bonding strength between resin and fabric increased by 104%. At the same time, the dye uptake (98. 6%) and apparent dyeing depth (2. 7) of aramid fabric were greatly improved. The color fastness of the dyed fabric has been effectively improved, and the color fastness to friction can meet the requirements of clothing fabrics. The modification of aramid fiber with resin pretreated by ozone plasma has certain reference significance for improving the dyeing properties of aramid fibers. © 2022 China Textile Engineering Society.
