Isacord 1000m 聚酯纖維 1200 夕陽橙縫紉線

The strength is the big selling point for me—it’s held up through dense satin stitches without a single break. Smooth through the needle, too, and the 1000m spool means I’m not swapping cones mid-project.

This thread runs through my machine like butter — zero shredding or tangling even on dense satin stitches. The polyester strength is obvious, it held up through a dozen washes on a work uniform without a single break.

I switched from rayon to this polyester thread for a project and the difference in strength is immediately noticeable—no breaks at high speed. The smooth finish glides through my machine without any lint buildup.
