      abstract = {Coloration of fabric is a foremost process in the production of textile material. In this work, at first we collected 100% cotton knit fabric and then natural dye was extracted from onion skin and used to dye cotton fabrics using selected natural and synthetic mordants. The natural mordants were aloe vera,  vinegar, lemon and synthetic mordant is acetic acid. Cotton fabrics were dyed using each of the selected mordants under conventional mordanting techniques (post-mordanting), adopting the recognized vat dyeing method. The dyed fabric samples were permitted to age for a day and then washed in standard industrial detergent solution. After dried the fabric, we assess color fastness of this fabric. For assessment of color fastness of this fabric we tested for color fastness to washing, color fastness to light, color fastness to perspiration, color fastness to rubbing. We also tested color strength of this fabric. We got color fastness of this fabric was moderate. We also evaluated the color deviation of this fabric by means of spectrophotometer. It was concluded that onion skin dye with lemon and acetic acid as mordant under post-mordanting technique gave the best result of color fastness of the onion skin dye.},
