摘要
介绍了过硼酸钠(SPB)漂白的原理,探讨了过硼酸钠用量、温度、时间、pH值及稳定剂乙二胺四乙酸二钠(EDTA-2Na)用量对棉织物漂白效果的影响,比较了过硼酸钠优化工艺漂白与氧漂工艺的漂白效果和染色性能。结果表明,过硼酸钠漂白棉织物的最佳工艺为:过硼酸钠6 g/L,稳定剂EDTA-2Na 1.5 g/L,渗透剂JFC 1 g/L,pH值为10.0,60℃漂白60 min。过硼酸钠60℃漂白棉织物基本达到过氧化氢90℃漂白棉织物的效果,且断裂强力损失率低,其活性染料染色比过氧化氢漂白棉织物的染色性能稍好。
In this article, the bleaching principle of sodium perborate （SPB） is introduced, meanwhile, the ef-fects of dosage of SPB and stabilizing agent ethylenediamine tetraacetic acid disodium salt （EDTA-2Na）, tempera- ture, time, pH value on bleaching are discussed. The bleaching effects and dyeing property after bleaching by SPB in optimum conditions and by hydrogen peroxide respectively are compared. The results show that the optimum bleaching process using SPB are： 6 g/L dosage of SPB, 1.5 g/L dosage of EDTA-2Na, 1 g/L dosage of penetration agent JFC, pH value of 10.0, dyeing at 60 ℃ for 60 minutes. It also points out that the effects of SPB bleaching at 60 ℃ is the same as that of hydrogen peroxide bleaching at 90 ℃, and fabric breaking strength of the former is reduced. Besides, dyeing property of fabrics after bleaching by SPB is better that of fabrics after bleaching by hy-drogen peroxide.
