An exceptionally soft texturized nylon sewing thread for soft, comfortable next-to-skin fluffy seams

Coats Surfilor is an exceptionally soft texturized nylon sewing thread which produces seams with a luxurious feel.

This fluffy thread has excellent extensibility and good sewing performance. The inherent crimp properties of Surfilor deliver excellent seam coverage, therefore giving exceptional seam comfort in your garments. It is suitable for use in the loopers of overlocking, serging and cover seaming on jersey knitted fabrics.

Surfilor makes it possible for you to create exceptionally soft seams where a nylon thread is preferred over polyester, ideal for "next-to-the-skin" applications. In addition low friction sewing lubricant will help to provide good sewing performance.

Surfilor is certified to Öko-Tex Standard 100, class I, the most stringent class covering textile items for babies and toddlers. It meets our Coats restricted substance list.

The softness of a seam relates to a number of factors including the exact choice of thread in needle and spreader, fabric, sewn seam direction, stitch density and thread tension.

Please refer to our technical bulletin on Soft and Secure Seams or further guidance.

Nylon has lower wash fastness properties than polyester and we recommend to take extra care when using textured nylon looper or cover threads in combination with polyester needle threads as a color difference is likely to emerge with frequent domestic washing during the lifetime of the garment.
