Key Points for Equipment Adjustment
Thread tension is the critical factor in preventing thread breakage; the ideal state allows the embroidery thread to pass smoothly without fraying. When adjusting:
The upper thread tension knob is usually located on the right side of the machine head; turn it clockwise to increase tension.
Adjust the bobbin thread tension via the screw on the bobbin case; the thread should pull out smoothly with light force during testing.
Adjustments vary by thread material; synthetic threads require lower tension than cotton threads.
Daily Maintenance Essentials
Regular maintenance can reduce thread breakage issues by 80%:
Cleaning and maintenance: Clear lint buildup from the needle plate daily and lubricate guide rails weekly.
Component inspection: Replace worn needles monthly and check the bobbin case for deformation.
Environmental control: Maintain workshop humidity between 40% and 60% to prevent the thread from becoming brittle.
Improving Operational Techniques
Embroidering on uniquely shaped caps requires specific techniques:
Slow the speed to below 600 RPM when embroidering curved areas.
Secure multi-layered fabrics with positioning adhesive before embroidering.
When changing colors, trim the thread ends rather than pulling them, to avoid loosening the thread spool.
