What makes quality Rayon Thread?

Many people don’t know that Rayon, sometimes referred to as Viscose, originates from nature! The raw material needed for the production of viscose is cellulose pulp, and the original material for the pulp production is wood.

Cellulose is the natural building material needed by plants for forming their cellular walls. There are only a few wood types where the cellulose develops the properties required for the production of viscose. In most cases, pine or spruce wood, or even well selected deciduous tree types, are used.

One of the special features of cellulose is that the molecules are connected with each other in chains, and the length of the chain is critical for producing the highest quality raw viscose fibers. Long-chain, consistently high quality cellulose molecules are the best prerequisite for reprocessing cellulose into a perfect viscose product.

The world renowned ENKA plant in Obernburg, Germany, produces raw viscose fibers exclusively from long-chain, consistently high quality cellulose molecules, and all Sulky Rayon Threads are made exclusively with ENKA raw fibers, which have been tested and certified to be the highest quality rayon/viscose fibers in the world.

The trees that ENKA’s raw viscose fibers are produced from are substantially better because ENKA strictly controls every working step from cultivating the right trees on plantations with optimal climatic and geologic conditions for 20 years, to reprocessing only the highest quality long-chain cellulose fibers.

That’s why you experience less breakage with Sulky/ENKA threads, even when using high-speed embroidery machines, and why everything you make using Sulky/ENKA threads lasts longer and looks better years from now. Granted, all this may not be apparent when you’re just looking at a 40 wt. rayon thread. But put Sulky/ENKA fibers and any others under a microscope and you’ll see the difference.

Because ENKA fibers have a more even form and structure, they can be dyed more evenly. ENKA fibers also have more perfect optical refraction and cleanness of yarn to make Sulky Rayon threads appear glossier and more brilliant. That’s why embroidery connoisseurs prefer the softer, warmer, more natural look of Sulky Rayon Thread. It’s no wonder Sulky 40 wt. rayon threads are the strongest, most brilliant rayon threads available.

Other important tested elements that prove the high quality of Sulky/ENKA Rayon thread are Tensile Strength, Stress Elongation and Fibril Breakage.

As you can see from the pictures here, fibril breakage of the “no-name” fibers will lead to, at the very least, an untidy embroidery result with lint formation on the embroidered surface and, in the worst case, to thread breakages while embroidering. You can see that Sulky/ENKA viscose has an excellent cleanness of the fibers that cannot be found in “no-name” viscose of other origins.
