【摘要】 用新型双氧水漂白活化剂OD对纯棉织物进行冷轧堆一浴法前处理。讨论了H₂O₂用量、NaOH用量、活化剂OD用量、堆置时间对前处理效果的影响,确定了双氧水活化剂OD在冷轧堆前处理中的最佳工艺为:27.5%H2O230 g/L,NaOH 25 g/L,活化剂OD 10 g/L,前处理助剂5 g/L,稳定剂硅酸钠8 g/L,堆置时间10 h。该工艺条件下,织物白度达到80.9,毛效8.7 cm/30 min,断裂强力516.1 N。新型双氧水活化剂OD可使堆置时间、耗能减少,耗碱量下降,并有效改善了纯棉织物前处理的品质。更多还原

【Abstract】 The cotton fabric was processed to a cold pad-batch pretreatment with a novel hydrogen peroxide bleach activator OD in one step. The effects on pretreatment with H₂O₂ dosage, NaOH dosage, the activator OD dosage, stacking time were discussed. The optimum process was as follows: 27.5% H₂O₂ 30 g/L, NaOH 25 g/L, activator OD 10 g/L,pretreatment auxiliary 5 g/L, sodium silicate 8 g/L, stacking time 10 h. According to the process conditions, the fabric whiteness, capillary effect and breaking strength were up to 80.9, 8.7 cm/30 min, and 516.1 N, respectively. The new hydrogen peroxide activator OD could reduce stacking time, energy consumption and alkali dosage, improving the cotton fabric pretreatment quality effectively.更多还原
