Sewing thread Brother Alterfil Diegs Grey 24550 1000m - polyester, 1000 m spool

Brother Alterfil Diegs Grey 24550 is a 1000 m spool of polyester sewing thread in a neutral grey shade. Designed for general sewing and machine use, this thread provides consistent thickness and smooth feeding suitable for seams, topstitching and repairs on a variety of fabrics. The long 1000 m spool reduces the need for frequent thread changes, making it practical for higher-volume home sewing, garment production and craft projects.

Advantages

The polyester construction offers good tensile strength, minimal stretch and resistance to abrasion and washing, maintaining seam integrity over time. The even twist and uniform diameter ensure stable stitch formation and reliable machine performance with reduced lint and fewer thread breaks. The neutral grey colour blends well with many fabrics and is suitable for concealed seams or visible topstitching depending on design needs.

• Apparel sewing and garment construction

• Repairs and alterations
• Machine sewing and serging
• Craft projects and decorative topstitching

How to use

Thread the spool through the machine’s thread path and tension settings according to the sewing machine manufacturer’s instructions. Use an appropriate needle size for the fabric and thread weight to ensure balanced stitches. Test stitch on a fabric scrap to adjust tension, stitch length and needle choice before working on the main piece. For best results, replace or clean the bobbin case and remove accumulated lint regularly during extended sewing sessions.

Usage recommendations

For general sewing tasks select a needle size compatible with medium-weight fabrics (for example universal needles size 70/10–90/14 dependent on fabric). When topstitching or sewing heavy seams, increase needle size and adjust stitch length. Store the spool in a dry, dust-free place and avoid prolonged exposure to direct sunlight to preserve colour and fibre quality.
