（3）冷堆：将浸轧后的坯布在20-28℃进行冷堆6-10h；
（4）氧漂：用50-70℃温水洗涤冷堆后的坯布3-5次，然后放入氧漂液中进行氧漂，所述氧漂液以重量份计，其组分为10-20份氧漂助剂、双氧水5-10份、渗透剂JFC1-3份；
（5）气蒸：将氧漂后的坯布在气蒸机上进行气蒸，气蒸时间为15-30min，气蒸温度为80-100℃；
（6）水洗烘干：将气蒸后的坯布用50-70℃温水洗涤3-5次后，再在60-80℃下烘干。
进一步的，所述步骤（1）中表面活性剂为聚硅氧烷、聚乙二醇和天然脂肪醇中的一种。
进一步的，所述步骤（1）中搅拌速度为100-300rpm。
进一步的，所述步骤（2）中浸轧为一浸一轧、二浸一轧或二浸二轧中的一种。
