摘要
采用增深匀染剂Intratex LPUA对超细锦纶PU合成革进行预处理再进行酸性染料染色,预处理工艺为:Intratex LPUA 5%(omf),70℃处理20 min,浴比1:20。试验结果显示,超细锦纶PU合成革采用Intratex LPUA预处理,可明显提高染品的染深性,K/S值提高20%～40%,不会出现白霜或白点,不会影响染品的牢度性能。此外,采用Intratex LPUA预处理,可以大大减少染料的用量,减轻废水处理负荷。
Pretreatment of superfine PA/PU synthetic leather was carried out with a deepening and leveling agent Intratex LPUA followed by acid dyeing. Pretreatment was undertaken at 70℃; for 20 minutes with Intratex LPUA 5% （omf） and bath ratio 1：20. The results showed that pretreated with Intratex LPUA, the dyeings featured deeper shade, increased K/S value by 20% -40%, good color fastness and dyeing quality without hoar-frost or white points. In addition, pretreatment with Intratex LPUA could reduce dye usage and burden on wastewater treatment.
