WHAT MAKES SURI FIBER UNIQUE
Suri is silky and lustrous, and these qualities can be attributed to the structure of Suri at the microscopic level. All animal fibers are made up of cortical cells in the center core of the fiber with scales similar to a fish on the outside. These scales hug one another closely. The photos to the right are electron micrographs- photos taken with an electron microscope. The top photo is of a merino sheep fiber. Note that the fiber is not smooth and the frequency or number of scales. The next fiber is cashmere. Its scale edges protrude from the fiber more than the merino. Finally, in the photo of the Suri fiber, you can see the that the scales are longer and barely protrude from the fiber. This structure gives Suri that silky hand and allows it to reflect light better than most animal fibers.
In other animal fibers, including the huacaya alpaca, the cortex has two halves that have different consistencies. Without getting too technical, this causes the fiber to twist as it grows and causes the fiber to crimp or form a zig zag pattern. Suris have a different cortex structure. In Suris, the fiber's cortical cells are spaced randomly, so there is no crimp in Suri, so the fibers are straight.
While we may not be able to feel the individual scales, we can feel how the fibers interact with one another as they slip and slide in a group. Suri fiber generally has longer scales and those scales hug the cortex more closely than what is generally seen in other animal fibers. These longer scales combined with a scale height that is almost indiscernible under the microscope allow light to reflect evenly thus giving Suri a beautiful luster.
So when using Suri keep in mind the special qualities that make Suri Simply Stunning:
