Product Details

MH 75D/2 cocoon bobbin thread is a pre-wound 100% polyester bobbin thread in black, known in the trade as schiffli back yarn, supplied ready to load rather than wound on site.

Key Selling Points

• Consistent bobbin build: MH cocoon bobbins are wound with low variation in size and shape, so embroidery and quilting machines hold their tension setting from one bobbin to the next.

• Clean run-outs: Controlled yardage and winding tension let each bobbin unwind smoothly to the end, reducing thread breaks and stoppages on long production runs.

• Built as an under thread: The thread is engineered to sit behind the face embroidery without shadowing through or disturbing the top stitch.

• Dark-ground ready: The black shade keeps the bobbin side invisible on dark fabrics and dark embroidery, where a light bobbin thread would show at the stitch edge.

• Ready to load: Pre-wound cocoons remove bobbin winding from the plant's workflow, which saves labour on multi-head and schiffli operations.

• Range beyond one article: MH runs the same cocoon format in other deniers and fibres, so a plant can standardise its bobbin supply across machine types.

Schiffli Back Yarn Material

These Schiffli Back Yarns are available in a wide range of fiber types, including trilobal polyester, spun polyester, cotton-polyester blends, filament rayon, mercerized cotton, and nylon filament.

Here is a breakdown of the Schiffli Back Yarns for specific yarn deniers and ply counts, along with their typical applications and characteristics:

Schiffli Back Yarn Size Chart: 6#, 7#, 9#, 10#

The size number refers to the physical size of the bobbin thread itself (not the yarn’s denier or ply). The numbers are often used to denote the diameter or capacity of the bobbin, with larger numbers generally indicating bigger or more capacity for longer yarn lengths.
