OPTIM™ fiber treatment gives wool a silk like quality for extremely fine, soft and light weight fabrics. This unique technical development and innovation provides a revolutionary technology. OPTIM™ technology creates a wool fiber with a super light weight silky feel.

OPTIM Fine™ is a new generation of ultra fine wool fibers with a structure and physical properties that closely resemble silk. This gives weavers the scope to create high quality, sophisticated, lightweight fabrics that are super soft to handle. Fabrics made from OPTIM Fine™ fibers have a silk-like touch, fluid drape, distinctive sheen and subtle luster, plus all the natural performance benefits of wool. 

X-rays show that the processed fiber is closer to silk in structure, while being stronger and finer than its parent wool. A further benefit of the technology is that it can be used to produce a fiber that has the potential to provide light, warm garments by inducing latent effects in the modified fiber.

Finer fibers make light-weight yarns possible in today's spinning environment, while the bending properties of fine fibers provide the required softness. Not only is the linear density of fibers reduced, but the X-sectional profile (below) and the surface luster of the fibers is different as well.

The advanced equipment developed to produce OPTIM Fine™ fabrics uses twisted wool sliver which stretches a 19 micron wool fiber some 40-50%, making each fiber 3 to 3.5 micrometers significantly finer. The reduced micron fiber is then chemically set in this finer form. The result is a fine, lustrous silky soft and strong fiber.
