New brothread Polyester Bobbin Thread 2×5000M (White & Black) — 70D/2 60WT, Smooth High-Tenacity Spools

These oversized polyester bobbin spools deliver consistent tension and exceptional length so you can wind many pre-wound bobbins without frequent refills. Made from high-tenacity polyester filament 70D/2 (60WT), the thread balances strength and smoothness to feed reliably through bobbin cases and tension discs. The set includes two huge spools, each containing 5000 meters (about 5500 yards), in essential white and black shades for everyday sewing and embroidery needs.

How does this bobbin thread keep machine tension steady?

The New brothread polyester filament is manufactured to uniform thickness and finish, which reduces draw-off variability during stitching. That consistent construction helps prevent skipped stitches and uneven bobbin tension over long runs.

• High-tenacity polyester 70D/2 (60WT) for uniform diameter and strength
• Smooth finish for reliable passage through bobbin cases and tension springs
• Long spool length reduces thread joins and tension fluctuations

Will these spools save time and money for frequent sewers?

Yes—each spool contains 5000 meters (approx. 5500 yards), so you wind or load far fewer spools compared with standard-sized reels. Buying two large spools in core colours reduces reorder frequency and lowers cost per meter for regular sewing and embroidery projects.

• 5000M / 5500Y per spool minimizes downtime for re-threading or reloading
• Economical pricing aimed at hobbyists and small production runs
• Basic white and black cover most bobbin colour needs without extra purchase

How do I use these large spools with my machine?

You can wind your own pre-wound bobbins or feed the spool directly using a plastic thread stand or spool holder. New brothread recommends blank bobbins and a dedicated stand so the oversized spool fits your machine smoothly.

• Use blank bobbins to create custom pre-wound bobbins for quick changes
• Pair with a plastic thread stand for stable, tangle-free feeding
• Compatible with most domestic and commercial embroidery and sewing machines when wound properly

What colours and situations are these spools best for?

This two-pack includes classic white and black—practical for lining, seams, and when the bobbin colour must blend with fabric or top thread. They are especially useful for projects where consistent bobbin performance is more important than matching specialty colours.

• White for light fabrics and general-purpose use
• Black for dark fabrics and contrast-free bobbin layers
• Ideal for sample stitching, production sewing, and continuous embroidery runs

Who is this for? The New brothread 2×5000M bobbin thread set is built for home sewists, embroidery hobbyists, and small-scale production users who want fewer spool changes, dependable bottom-thread performance, and basic colour coverage. If you wind your own bobbins, run long embroidery jobs, or want a cost-effective supply of consistent polyester bobbin thread, these heavy-duty spools are a practical choice.
