1. Process brief

1.1 The production of polyester staple fiber takes polyester (PET) melt as the raw material and sends it to the spinning machine; or uses polyester chips as the raw material, which is dried and melted and then sent to the spinning machine, and then is bundled, stretched, shaped, Crimping, cutting, baling, and obtaining polyester staple fiber.

1.2 The production of polyester fiber is made of polyester chips, which are dried and melted and then sent to the spinning machine; or the polyester melt is used as the raw material to be sent to the spinning machine, and the stretched twisted yarn, Stretch textured yarn, air textured yarn, full draft yarn.

Polyester staple fiber and polyester filament are combustible. The heat carrier biphenyl is combustible, explosive and toxic.

Two, safety points

2.1 Control the operation of chip drying and melt spinning to promote stable operation.

2.2 Screw extrusion melt spinning is heated by biphenyl heat carrier. Exhaust is required when the biphenyl heats up, and the exhaust should be slow to avoid taking the biphenyl out; open flames are strictly forbidden when exhausting, and must not be exhausted into the room to avoid fire and poisoning.

The temperature in this post is high, and the Department of Defense must do a good job in cooling down.

2.3 The winding speed of the winder is very high, and it is easy to bring the hook in accidentally during operation, causing the flying hook to hurt people. Therefore, it is necessary to educate the manipulator to concentrate on maneuvering and stand in a favorable and safe position to avoid flying hook injury.

When winding the wire on the waste wire roll, if there are several strands of wire on the roll, use one hand to hold the original tow when rewinding the wire to prevent the tow from winding the hooks and causing flying hooks.

When cutting the waste wire on the waste wire roller, be sure to step on the brake device with your foot, and use the knotting knife to cut the waste wire after it stops.

2.4 When raising and lowering the cluster frame, it is strictly forbidden to stand under the frame.

2.5 When handling the drafting winding roll, be sure to reduce the speed or stop processing. When hooking, concentrate on hooking at the exit to prevent hooking.

2.6 Be careful not to spill the oil. Once it spills on the ground, it should be washed in time to prevent slipping while walking.

2.7 When the cutting machine is turned on and raises the head, hold the wire head and feed it into the cutting hook wheel. If it is not matched properly, it is easy to happen that the hand has not left, and the console is turned on and the hand is brought in, causing a hand cutting accident. Therefore, the operation of the cutting machine must be closely coordinated, and the machine must be turned on after the hand is removed.

2.8 During the packing process, the main gland covering cloth should be put on when the machine is stopped, and then the main gland should be raised. Do not use the main gland wrapping cloth when raising the gland to prevent squeezing your hands.

2.9 Do a good job in the fire prevention of fiber warehouses.

2.10 "Shawl hair" is not allowed to work. Female comrades should cover their hair in work caps, and are not allowed to wear high heels or jewelry.

2.11 The factory building is noisy, so pay attention to personal protection.

2.12 Maintenance workers should wear protective equipment when they go to high-temperature posts for inspections to prevent burns.
