The results indicated that the optimum OBEOP condition was showed as enzyme OX-1 of 4.5 g/L, 30% H2O2 of 15 g/L, temperature of 95 ℃, processing time of 40 min, pH value of 10~0.5, bath ratio of 1:30. It is found that the whiteness, woolliness and the strength loss with enzyme was superior to those treated with traditional sodium silicate process. Adding urea in OBEOP can help to improve the fabric whiteness, woolliness and reduce the strength loss.

试验结果表明：棉织物酶氧一浴最佳工艺条件为：净棉酶4.5g/L，双氧水12mL/L，温度95℃，处理时间60min，pH值10~10.5，浴比1：30；经净棉酶处理后棉织物的白度和毛效优于碱氧退煮漂一浴法工艺，而且织物的强力损失少；在棉织物酶氧一浴法工艺中添加尿素，有助于提高织物白度、毛效，并能减小强力的损失。

In addition to their higher thermal stability, neoalkoxy titanates offer somewhat enhanced final properties compared to monoalkoxy counterparts; according to Monte, the properties obtained with monoalkoxy coupling agents are about 92% of those with neoalkoxy variants.

除了具有高的热稳定性，比单烷氧基钛酸酯提供更高的最终性能。按照 Monte 的说法，单烷氧基钛酸酯获得的性能大约是新烷氧基钛酸酯的92%。
