This yarn is a Viscose Chainette 10/167, a knitted viscose thread approximately 3mm in width. It is a 167 denier viscose filament knit on 10 needles in a circular fashion and is tubular in construction. I have prewashed it with Synthrapol & rinsed well. It has been divided into 12 yard sections & rolled onto a paper tube. I suggest rewashing if you plan to dye it yourself, to remove fingerprints or other oils/grime deposited since initial washing.
Rayon can be dyed beautiful deep colors, pastels or anything you can imagine with fiber reactive procion dyes. I have not tried grocery store brands so can't comment on those.
Each listing is for ONE 12 yard length of UNDYED ribbon!
