棉织物的复合茶皂素前处理

Pretreatment of cotton fabric with combined tea saponin

采用复合茶皂素（卜公茶皂素）对棉织物进行前处理，优化的卜公茶皂素汽蒸退煮漂一浴工艺为：茶皂素40g/L，渗透剂JFC5g／L，精练剂YSl986g／L，双氧水稳定剂GJ一1014g／L，浸轧（多浸多轧，50℃）→汽蒸（95～100℃，50～60min）→热水洗（100℃）→冷水洗→烘干。结果表明，采用b公茶皂素对棉织物进行退煮漂一浴前处理的效果好于常规碱氧工艺。

Cotton fabric is pretreated with combined Bugong tea saponin. The optimum one bath process of desizing-scouring- bleaching with Bugong tea saponin is carried out at 50℃with tea saponin 40 g/L, penetrating agent JFC 5 g/L, scouring agent YS198 6 g/L and stabilizing agent G J-101 4 g/L, dipping and padding many times, followed by steaming at 95 - 100 ℃ for 50 - 60 minutes, washing with hot water and cold water, and then drying. The results show that cotton fabric treated with the new one bath process can obtain better pretreatment results than that treated with conventional alkali-peroxide process.
