Abstract
The main objective of thestudy was to assess the colour fastness properties of dye extracted from guinea
corn leaves on cotton fabric. Specifically,the objectives were to; assess the light fastness of dye extracted
from guinea corn;assess the rubbing fastness of dye extracted from guinea corn;and the washing fastness
of dye extracted from guinea corn. Cold maceration and soxhlet extraction were employed using distilled
water and acetone as solvents. The dye was produced in four states using distilled water and acetone in
mecaration and the yield were wine and slightly deep wine respectively while in soxhlet extraction, distilled
water plus sample and acetone plus sample yielded slightly reddish brown and reddish brown. The extracted
dyes were applied on cotton fabric treated with alum. The colours after dyeing yielded blush, deep blush,
brick and deep brick respectively.Light,rubbing and washing colour fastness were tested using cotton fabric
treated with alum. Most of the fabrics dyed with dye extracted using maceration have lower rating on grey
scale than those with soxhlet. It is therefore recommended among others that effort should be made in using
better yielding techniques in extracting dye for better fastness.
