FAQs
What type of sewing machine is this thread for?
This thread is specifically designed for overlock (serger) and coverlock machines. It is generally too thick for standard sewing machines.
Can I use this thread for quilting or embroidery?
No, Bulky Lock 80 is not intended for quilting or embroidery. It is optimized for the looper mechanics of overlock and coverlock machines to create soft, elastic seams and finished edges.
How does Bulky Lock 80 differ from regular serger thread?
Bulky Lock 80 is thicker and more elastic than standard serger threads, designed to create softer, more comfortable seams and provide excellent coverage for cut edges on stretch fabrics.
What fabrics is this thread best suited for?
It is ideal for knit fabrics, stretch materials, activewear, lingerie, and for finishing edges on a variety of garments and home decor items where a soft, durable seam is desired.
How do I adjust the tension for this thread?
Tension settings will vary by machine and fabric. It is recommended to start with lower looper tension settings and perform test stitches on a fabric scrap, adjusting as needed until a balanced stitch is achieved.
What does 'Bulky Lock 80' mean?
'Bulky' refers to its thickness and bulk, designed to provide coverage. 'Lock 80' indicates its suitability for overlock/coverlock machines and its construction characteristics. The '80' denotes its tex value or thickness, with lower numbers generally indicating finer threads, though 'bulky' threads deviate from this norm.
Troubleshooting
Thread breaking frequently
Check machine tension settings; Bulky Lock 80 may require lower looper tension. Ensure the machine is correctly threaded. Verify that the needle is appropriate for the fabric and thread combination. Check for any burrs or obstructions in the looper path.
Uneven or messy seams
Adjust differential feed on your overlocker. Ensure the thread is properly guided through all tension discs and guides. Test on a fabric scrap to fine-tune tension and stitch settings.
Thread tangling in loopers
Ensure the thread is not catching on the spool or the spool pin. Double-check that the thread path is clear and the thread is seated correctly in all guides and tension discs.
