【摘要】 采用"媒染预处理-氧化漂白-还原漂白"3阶段工艺方法对驼绒进行脱色,研究了媒染温度、H₂O₂用量、氧化温度、氧化漂白时间、还原剂种类对驼绒脱色后的白度和纤维断裂强力的影响。运用正交试验综合评分法,得出驼绒纤维脱色的优化工艺条件为:预处理阶段:FeSO₄ 15%（owf）、NaHSO33 g/L、浴比1∶40,媒染温度40℃,处理时间40 min;氧化漂白阶段:焦磷酸钠8 g/L、H₂O₂用量25 g/L、氧化温度50℃,漂白时间120 min;还原漂白阶段:焦磷酸钠2 g/L、保险粉1 g/L,温度50℃,还原时间60 min。优化工艺获得的脱色驼绒纤维具有较高的白度,且纤维损伤小。更多还原

【Abstract】 "Mordant pretreatment-oxidation bleaching-reduction bleaching"is used as a three-stage bleaching process method to decolorize camel hair. The influence of mordant temperature,H₂O₂ dosage,oxidation temperature,oxidation time and reducing agent species on whiteness and fiber breaking strength is researched,then the process conditions of the decolorization of camel hair is optimized with orthogonal analysis using comprehensive scoring. The optimized pre-mordant processing is Fe SO₄ 15%,Na HSO33 g/L,bath ratio 1 ∶ 40,treating at 40 ℃ for 40 min. The optimized oxidation bleaching is sodium pyrophosphate 8 g/L,H₂O₂ 25 g/L,bleaching at 50 ℃ for 120 min. The optimized reduction bleaching is sodium pyrophosphate 2 g/L,sodium hydrosulphite 1 g/L,reducing at 50 ℃ for 60 min. It is obtained higher whiteness and less damage for camel hair by using optimized process.更多还原
