Sewing thread Brother Alterfil 34871 Lilac color 1000 m spool

Brother Alterfil 34871 lilac sewing thread on a 1000 m spool is a polyester thread designed for general sewing and machine use. The long spool length reduces spool changes and supports continuous stitching for garment construction, repairs, quilting and decorative seams. The thread's consistent thickness and smooth finish make it suitable for both domestic and many industrial sewing machines, helping maintain even stitch formation across a variety of fabrics.

Advantages

The polyester construction provides good tensile strength and moderate elasticity, offering reliable performance in seams that require durability and some give. The long 1000 m spool minimizes interruptions during large projects, while the smooth surface reduces friction in machine tension discs and guides. The lilac colour is colourfast under normal laundering conditions and works well for visible topstitching or matching thread needs in apparel and home textiles.

Suitable for

• Garment sewing and alterations
• Quilting and patchwork
• Home décor items such as curtains and cushions
• Decorative topstitching and embroidery outlines
• Small to medium industrial and domestic sewing machines

How to use

Use this Brother Alterfil polyester thread as the top thread in your sewing machine and pair it with an appropriate bobbin thread for balanced stitch formation. Thread the machine following the manufacturer's routing and set the tension according to the fabric weight: lower tension for lightweight fabrics and slightly higher for heavier materials. Test stitches on a scrap of the same fabric and adjust needle size and stitch length as needed to achieve even, secure seams.

Usage recommendations

Store the spool in a dry, dust-free environment away from direct sunlight to preserve colour and strength. Replace thread if you notice fraying or colour fading. For best results on delicate fabrics, use a fine universal or microtex needle and a lower presser foot pressure.
