The precautions for using a one-step false twisting machine mainly include the following aspects:
1、 Preparation and inspection before startup
Equipment inspection: Ensure that the one-step false twisting machine is in good working condition.
Check if all components are intact, especially key components such as tension adjustment device, yarn guide device, and spindle.
Check if the hot box, heater, and cooling system are working properly.
Cleaning work: Keep the equipment clean and regularly clean yarn, dust, and debris.
Use a vacuum cleaner or appropriate cleaning tool to clean the machine surface at least once a day to prevent dust accumulation from affecting equipment performance and generating noise.
2、 Process parameter adjustment and setting
Double twist and spindle speed: Select the appropriate double twist and spindle speed based on the physical properties of the twisted yarn raw material, fabric feel, mechanical properties, and other factors.
The twist of the silk thread is generally low to ensure that the fabric wrinkles are delicate and full.
Gas coil tension: Different wires have different allowable tensions. When the spindle speed is too high, the gas coil tension may exceed the allowable tension, leading to yarn breakage and breakage.
Therefore, it is necessary to control the ingot speed and gas ring tension reasonably to ensure the strength and elongation index of the crepe.
Line speed: Set the line speed reasonably according to the equipment specifications and process requirements.
Pay attention to the relationship between line speed, ingot speed, and twist to avoid equipment damage or yarn quality degradation caused by overspeed operation.
Hotbox temperature: The heating temperature has a significant impact on the performance of the silk thread, and an appropriate temperature should be set according to the type of silk thread and process requirements.
The temperature should be kept consistent to avoid temperature fluctuations that may cause instability in the performance of the silk thread.
The heating time and cooling time also need to be adjusted according to the residence time of the wire in the hot box and the heating temperature.
3、 Operation and maintenance
Standardized operation: Operators should be familiar with the operating procedures and safety precautions of the one-step false twisting machine.
During the operation, close attention should be paid to the operating status of the equipment and the quality of the yarn, and process parameters should be adjusted in a timely manner.
Daily maintenance: Regularly check the lubrication condition of the equipment and add or replace lubricating oil in a timely manner.
Check and tighten the connecting bolts of each component to prevent loosening and equipment failure.
Clean the dust and debris inside the hot box and heater, and keep the interior of the equipment clean.
Troubleshooting: When a device malfunction is detected, it should be immediately shut down and the power should be cut off.
Conduct troubleshooting and maintenance based on the symptoms and causes of the malfunction, and if necessary, contact professional maintenance personnel for handling.
4、 Safety and Environmental Protection
Safety measures: During operation, appropriate protective equipment such as goggles and gloves should be worn.
Do not touch or adjust components while the device is running to prevent accidental injury.
Environmental requirements: comply with local environmental regulations and ensure that equipment emissions meet standards.
Reasonably use resources, reduce energy consumption and waste generation.
In summary, the precautions for using a one-step false twisting machine involve multiple aspects, including preparation and inspection before startup, adjustment and setting of process parameters, operation and maintenance, as well as safety and environmental protection. During use, these precautions should be strictly followed to ensure the normal operation of the equipment and stable improvement of yarn quality.
