Reactive dye formula for cotton/linen blending and preparing method thereof

The invention discloses a reactive dye formula for cotton/linen blending and a preparing method thereof. The reactive dye formula for cotton/linen blending is prepared from, by weight, 57-65% of dye, 0.1-1% of peregal, 0.4-0.6% of wet rubbing fastness improver, 1-5% of fixer, 0.1-1% of ricinoleic acid butyl ester sulphate, 0.1-2% of sodium hexametaphosphate, 0.5-1% of tributyl phosphate, 2% of soda ash, 20% of sodium chloride and the balance deionized water. The components are placed in a high-speed mixer or rotary mixer according to the formula for mixing, then wet particles are obtained through extrusion conducted by means of a pelletizer with the caliber of 1 mm, drying is conducted by means of a drier, and then polyhedron particles are obtained through sieving. The reactive dye formula for cotton/linen blending and the preparing method thereof have the advantage that by the adoption of the dye, the wet rubbing fastness and fixation rate of cotton/linen blended fabric are improved effectively.
