摘要:

针对芳纶难以使用常规工艺进行染色和印花加工等问题,通过臭氧等离子体预处理芳纶织物后结合树脂改性以提升染色性能。研究了臭氧等离子体预处理对树脂改性芳纶表面元素和形貌的影响,探究了改性后芳纶织物的分散染料染色效果。结果表明:单独的臭氧等离子体处理对芳纶的染色效果改善并不明显,而臭氧等离子体预处理引入了丰富的活性基团并构建了粗糙的界面,显著提升了树脂的均匀分散性,使树脂和织物间的结合强度最高可提升104%,同时,大大提高了芳纶织物的分散染料上染率(98.6%)和表观染色深度(2.7),染色织物的色牢度得到有效提升,耐摩擦色牢度可达到服装面料使用要求。

Abstract:

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.

Key words: aramid fiber, dyeing, plasma, pretreatment, resin modification
