羽绒染色工艺技术研究

Study on the down dyeing process

借鉴毛皮染色工艺制定羽绒染色工艺.在高温条件下采用红、黄、蓝三种希力F系列毛皮染料对羽绒进行染色,染色后的羽绒经过漂洗、烘干、除尘等工序后,对其进行水洗,之后检测水洗废液中的染料含量,从而确定染料上染率.分别考察染色温度、染料用量、染色时间、pH、固色剂用量、固色时间等因素对羽绒染色效果的影响,从而确定出最佳羽绒染色工艺.

The down dyeing process was designed according to the fur dyeing process.The down was dyed with red,yellow and blue dyes from Xi-Li brand at high temperature,respec-tively.Firstly,the dyed down was treated by rinsing,drying,dusting and other processes, then washed by water,at last,in order to measure the dye-uptake,the dye content in the washing waste was tested.To obtain the optimum process of the down dyeing,the impact of dyeing temperature,dosage of the dyes,staining time,pH,dosage of the fixing agent,fixing time and other factors were investigated.
