Fiber reactive dyes are most popularly used to dye cellulosic fabrics. They chemically react with fibers and form covalent bond with them. They have wide range of shades and stain the textiles in your desired shade.
On the other hand, pigment dyes have no auxo-chrome in it. They don’t form any bond with textttiles rather just sit on the top of the fabric. They need the help of binders to adhere the fabric. Here, no chemical reaction takes place.
If you want a pale or faded look for your garment then pick pigment. If you want consistent vibrant color with uniformity, years later that comes out after wash then you should go for fiber reactive dye.
