通过调整溶剂的配比和凝固浴温度，研究了溶剂比例和凝固浴温度对成膜性能的影响。

The effects of the rate of DMF/MEK and the temperature of condensing bath on the properties of PU films are studied.

凝固浴以双组分及三组分效果较好.

Compound coagulating bath of bicomponent or tricomponent were found having better molding effect.

用乙醇代替甲醇作凝固浴介质可纺性能良好.

The replacement of methanol by ethanol for coagulation goves a good spinnability.
