锦氨经编织物轧染工艺

Pad dyeing of nylon spandex warp knits

采用自制的黏合剂和防泳移剂对锦氨经编织物进行涂料连续轧染工艺试验。优化的染色工艺参数为:涂料用量≤5 g/L时,黏合剂15 g/L,防泳移剂6 g/L,轧余率50%～55%,预烘温度80℃,焙烘温度170℃,时间1 min。所染锦纶经编织物布面均匀,耐洗色牢度和耐摩擦色牢度能满足要求。

Continuous pad dyeing of nylon spandex warp knitted fabric is explored with self-made adhesive and anti-migrant a- gent. The optimum dyeing process is pigment less than 5 g/L, adhesive 15 g/L, anti-migrant agent 6 g/L, pick-up 50% - 55%,pre-curing at 80 ℃： and curing at 170℃ for 1 min. The dyeings feature good levelness and satisfactory color fastness to washing and rubbing.
