UNIFORM TENSION CONTROL
Our patented magnetic-core creates consistent delivery throughout the entire bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. Magnetic-core prevents backlash or over spin & eliminates the need for backlash springs.
FEWER BOBBIN CHANGES
Our magnetic-core bobbin offers significantly more stitches per bobbin, reducing defects & increasing productivity.
Fil-Tec uses only the finest quality, high tenacity polyester yarns to make our patented magnetic-core embroidery bobbin.
Advanced EB cross-link technology reduces lint & residual build-up in the bobbin case & tension spring. The result is a more trouble-free bobbin.
