锦纶织物印花工艺

Printing of polyamide fabric

从固色温度、色浆pH值、尿素用量等方面,分析了锦纶织物弱酸性染料印花的基本工艺.结果表明,尿素用量100～200 g/kg,pH值在6～7,蒸化时间10～12 min,并增加给湿装置,可提高染料的固色率.为保证印花后织物白底的白度,用冷水(温度低于70 ℃)充分喷淋,以去除浮色,并加入皂洗剂.

The general printing process of polyamide fabric with weak acid dyes was analyzed from fixing temperature, pH value of color paste and dosage of urea to fixation yield. As a result, the fixation yield of dyes increased under the condition of urea dosage 100 - 200 g/kg, pH value 6 - 7, ageing time 10 - 12 min and dewing equipment. In order to ensure the whiteness of white ground of printed fabric, cold water spraying to remove loose color, temperature lower than 70 ℃, and adding soaping agent should be carried out after printing.
