Ultra-smart, in-house designer Kerin tackles this week’s fiber dilema.

Q: “How should I wash bamboo-blend garments?”

A: To begin, Rayon-type cellulosic materials like viscose, bamboo, and Modal are much different than other plant fibers in that they do not retain strength when wet. They will stretch more than cotton, and can shrink unevenly. When blended into a springy yarn, the inelastic viscose fibers are not held straight, but they will tend to relax and straighten out (therefore stretching the yarn) when wet.
