Product information

Description

Brother Aerolock Madeira Dark Blue 8420 sewing thread on a 2000 m spool is designed for overlocking and serging work on both professional and home sewing machines. The thread provides consistent thickness and a smooth feed that helps achieve even seams and reliable edge finishes. Its formulation and construction make it suitable for use on stretch fabrics and multiple layers, where reduced breakage and uniform stitch formation are required.

Advantages

The Aerolock Madeira thread delivers stable tension and minimal lint generation, supporting uninterrupted sewing sessions. Its smooth surface reduces friction in loopers and needles, which decreases the frequency of thread breaks and skipped stitches. Available in a deep dark blue shade, the thread maintains colorfastness under normal laundering and handling, ensuring durable seams and professional-looking finishes.

Suitable for

  • Overlocking and serging on knit and woven fabrics
  • Edge finishing and seam reinforcement
  • Stitching stretch garments and activewear
  • Multi-layer fabric assemblies and home sewing projects

Key specifications

  • Color: Dark Blue
  • Length: 2000 m per spool
  • Thread type: Overlock / serger thread
  • Compatibility: Suitable for domestic and industrial overlock/serger machines
  • Performance: Smooth feed, consistent thickness, reduced lint

How to use

Wind the thread onto the looper and needle according to your machine's threading path, maintaining recommended tension settings for overlocking or serging. Test-stitch on a fabric scrap to adjust stitch length and differential feed when working with stretch or thin materials. Replace the thread spool when the remaining length becomes insufficient to maintain consistent tension during longer seams.

Usage recommendations

Use a needle and machine settings appropriate for the fabric type; for stretch fabrics choose stretch or ballpoint needles. Keep the machine clean and regularly remove lint to preserve smooth feed. Store the spool away from direct sunlight and excessive humidity to maintain color and performance.
