拔染印花機烘房的溫度,一般情況下不得高于100°C,以低溫烘干為宜,烘燥溫度過高,為降低加工錫的拔染效果。染底不超過120°C,軋底刮底烘干不要超過100°C,低溫烘干為宜,烘干過程中不宜中途停機。加工錫對網(wǎng)版、設備的腐蝕性較大,正常情況下,生產(chǎn)5000米,務必檢查網(wǎng)版,防止出現(xiàn)砂漏,線條不光潔等。印花機刮刀壓力調(diào)節(jié)要均勻,要打好接版樣。拔染糊料一般采用白糊精或合成龍膠,脫糊性比海藻酸鈉差,所以使用繩狀式水洗機且要加強還原清洗,使布面清爽、色光純真、花型輪廓分明。
The temperature of the drying room of the printing machine is generally not higher than 100 degrees C. It is suitable for drying at low temperature. The drying temperature is too high, so as to reduce the discharging effect of tin. The bottom should not exceed 120 degrees C, and the bottom should not be dried at 100 degrees C. It is advisable to dry at low temperature. Tin processing is more corrosive to screen and equipment. Under normal circumstances, the production of 5000 meters must check the screen, prevent hourglass, and the lines are not bright and clean. The pressure adjustment of the blade of the printing machine should be uniform. The extraction paste usually uses white dextrin or synthetic dragon glue. The deactivation is worse than sodium alginate. So it is better to use the rope type washing machine and strengthen the reduction cleaning to make the cloth face clear, pure color, and the outline of the flower shape.
