A brief description of the process of polyester staple fiber

1.1 The production of polyester staple fiber is fed into a spinning machine using a polyester (PET) melt as a raw material; or a polyester chip as a raw material, after being dried, melted, and fed to a spinning machine, and then bundled, drawn, and shaped, Curling, cutting, packing, and obtaining polyester staple fiber.

1.2 The production of polyester filament is polyester chips as raw materials, after drying, melting into the spinning machine; or polyester melt as raw material into the spinning machine, after different post-processing to obtain a twisted twisted yarn, Stretch textured yarns, air textured yarns, and fully drawn yarns.

Polyester staple fibers and polyester filaments are flammable. The heat carrier biphenyl is flammable, explosive and toxic.

Second, the safety points of polyester staple fiber

2.1 Control the operation of slice drying and melt spinning to promote smooth operation.

2.2 Screw Extrusion Melt spinning is heated with a biphenyl heat carrier. When biphenyl heats up, it needs to be exhausted. The exhaust gas should be slow so as not to bring out the biphenyl. It is strictly forbidden to approach the open flame during exhaust. It must not be discharged into the room to avoid ignition or poisoning.

The temperature in this position is high and it is necessary to do a good job in the cooling of the Department of Defense.

2.3 The winding speed of the winding machine is very high, and the hook is brought into the device slightly during the operation, causing the flying hook to hurt. Therefore, it is necessary to educate the operators to concentrate their efforts on the safe and safe positions in order to avoid flying hook damage.

When winding the filament on the waste wire roller, if there are several threads around the roller, one hand should be used to hold the original one when the wire is wound so as to prevent the wire bundle from dragging the hook and causing the flying hook.

When cutting the waste wire on the waste wire roller, it is necessary to use the brake device to step on the brake device. After stopping, use a knotting knife to cut off the waste wire.

2.4 When lifting and lowering the bundle rack, it is forbidden to station people under the rack.

2.5 When handling the roller, it must be decelerated or stopped. When hooking silk, concentrate and hook the wire at the exit to prevent hooking.

2.6 Keep in mind that the oil should not overflow. If it spills on the ground, flush it in time to prevent it from slipping.

2.7 When the cutting machine is turned up, the holding wire will be sent to cut the hook wheel. If the mismatch is not properly handled, the hand may not have left. The control panel has been turned on and the hand has been brought in, resulting in a cut accident. Therefore, the operation of the cutting machine must be closely coordinated and must be turned on after the hand is left.

2.8 During the packing process, the main gland cover cloth should be put on during the shutdown, and then the main gland cover should be raised. Do not press on the cover cloth when raising the cover to prevent it from being squeezed.

2.9 It is necessary to do a good job in the fire prevention of the fiber warehouse.

2.10 No “shawl hair” is allowed to work. Lesbian women wear their hair in their work hats and are not allowed to wear high heels or jewelry.

2.11 The noise in the factory building is large and attention should be paid to personal protection.

2.12 Maintenance workers should go to high-temperature positions for inspection and wear protective gear to prevent burns.
