湿法成网 wet-laid web湿态下将纤维制成纤网的工艺。主要加工长度8~10mm的纤维,可加工的最长纤维为30mm。纤维分散在含有化学助剂的水中形成悬浮液,利用造纸毛毯或网帘将悬浮液中的水滤去,沉积下来的纤维形成纤维网。其特点是生产速度高。
在湿法成网过程中,可以利用悬浮在水中的纤维形成纤维网。
In the wet process the web of fibers may be formed from a suspension of the fibers in water.
与干法成网相比,湿法成网成本低,而且生产速度高,可以使用废弃的纤维。
Wet laid webs are less costly than dry laid, they Can be formed more rapidly than dry laid, and they Can use waste fiber if that is desired.
可在干法成网工艺中使用不具有静电的湿法应用的短切原丝玻璃纤维,形成静电累积倾向下降的短切原丝毡。
The static free wet use chopped strand glass fibers may be used in dry-laid processes to form chopped strand MATS having a reduced tendency to accumulate static electricity.
