When pre-sizing spandex knitted fabrics, the Custom Flat Screen Printing setting temperature for spandex yarns produced by different manufacturers should be considered to be slightly different, and then the appropriate setting temperature should be selected. Generally, the content of spandex is less than 5%, and the knitted fabrics that are not severely curled during slitting can be directly open-width dyed after pre-sizing. If the content is greater than 5%, the knitted fabrics that affect the dyeing due to open-edge must be sewn after pre-sizing. Dyeing can only be done in a cylindrical shape, otherwise the dyeing problem caused by curling cannot be overcome. When knitting fabrics are dyed, select the appropriate cloth speed and nozzle pressure to achieve better dyeing results. The cycle time is preferably 2 to 3 minutes. The speed calculation formula is: cloth speed = cloth loop length / cloth cycle time .
1. Make sure to clean up the surrounding environment of the setting machine, the top of the machine, the appearance of the top flue, the screen inside the machine, and the cloth around the electric box before the shift every day.
2. Perform a thorough sanitation every 15 days, including the air outlet in the machine, take out the screen and use a vacuum cleaner to clean the cloth of the heat exchanger tube, remove the inspection opening of the top flue, and clean the cloth in the flue hair.
3. Open the check port of the exhaust fan to clean up the cloth and oil in the fan (Note: The main power supply of the setting machine must be turned off or the exhaust fan power supply has been turned off, and there must be someone to guard the power switch. It is strictly forbidden to arrange the exhaust Someone turned on the power switch by mistake during the fan).
4. Every employee should understand the use of dry powder fire extinguishers. There must be four or more people in each shift who will use fire hydrants to turn on fire pumps. We must not use fire extinguishers for non-fire fighting purposes. It is strictly forbidden to destroy, stack, or steal fire extinguishers and their parts.
5. Each employee must understand the escape route, and at the same time, ensure that the safe passage is unblocked. The special fire-fighting steam must be tested once every 15 days.
6. Where the temperature of the boiler is heated to more than 100 degrees, the setting machine should start the top exhaust fan and the oven circulating fan. When the boiler oil temperature has not risen enough, the temperature control table can be adjusted to zero. Temporarily not heating up is beneficial. The boiler heats up. If there is a power outage during the event, the oven door must be opened to cool down. Before shutting down, wait for the boiler oil temperature to drop below 100°C before shutting down.
7. If you want to shut down a Custom Flat Screen Printing, you must first adjust the temperature control meter to zero and open the case door to cool down. After cooling down, check whether the electric three-way valve is closed properly. If there are some malfunctions, please turn the manual valve. Close it well and don't let hot oil enter the oven.
