Reflective Thread 100 m by Brother — Madeira 9667, reflective embroidery/sewing thread, 100m spool

Reflective Thread 100 m by Brother — Madeira 9667 is a 100 metre spool of reflective embroidery and sewing thread designed to increase visibility in low-light conditions. The thread combines a reflective surface with a construction suitable for both machine embroidery and general sewing applications. It is intended for use on safety garments, outerwear, sports apparel and decorative trims where enhanced nighttime visibility is desirable.

Advantages

This reflective thread delivers increased visibility by reflecting light back to its source without significantly changing the hand or drape of the fabric. The 100 m spool size provides a practical supply for multiple projects while remaining compact for storage. The thread is compatible with common sewing and embroidery machines when used with appropriate tension and needle choices, and it produces clear, defined stitches that retain reflective properties after washing when cared for according to machine and garment instructions.

Suitable for

• Safety vests and workwear
• Running, cycling and outdoor sports apparel
• Backpacks, bags and outdoor gear
• Decorative accents and branding on dark or high-visibility fabrics

Key specifications

• Length: 100 metres per spool
• Intended use: reflective sewing and machine embroidery
• Material characteristics: reflective surface finish suitable for light reflection
• Compatibility: for use with standard home and industrial sewing/embroidery machines when using recommended needles and tension settings

How to use

Wind the thread onto the machine spool or use a suitable cone holder and thread the machine following the manufacturer’s threading path. Select an appropriate needle for embroidery or sewing and adjust upper thread tension to avoid puckering or breakage; test-stitch on a fabric sample before working on the final garment. Sew or embroider at moderate speed to reduce stress on the thread and achieve consistent stitch formation. Trim and secure thread ends according to standard sewing practice.

Usage recommendations

For best results, use a needle size and type recommended for decorative or technical threads, reduce machine speed when stitching dense designs, and pre-test washing and care on a sample to confirm reflective performance and colorfastness.
