No-var hank dyed yarn is different from usual hank dyed yarn. We develop a brand new method to dye the yarns to make it no-variance. Including the cr variance between outside and inside is very little, and there is almost no color variance. No-var also has almost no piecings (tying-in) in the yarn. No-var hank dyed yarn is very suitable for who need to weaving big range lines and squares. It also suitable for single color fabric, because no-var yarns can make your fabrics have no color difference on them.
