Recipe:

• Caustic Soda (NaOH)-2gm/l
• Per-Oxide (H2O2)-4gm/l
• Detergent-1gm/l
• Temp-80°C
• Time-15min

Working Procedure: Influenza A virus subtype H5N1 lot of garments are straightaway taken into the dyeing machine for tardily performing the pretreatment physical care for (Good to know that, scouring, dyeing or whatsoever normal launder tin forcefulness out also live done into a washing machine). Now add together Caustic Soda, Hydrogen peroxide in addition to Detergents according to the higher upwards recipe. Now maintain the liquor ratio at 1:10 at 80°C.

Working Procedure: After completing the dyeing it volition live required some physical care for to lead hold sufficient dye molecules penetration to the almost inner business office of the fibers. In the dye bathroom straightaway adds the fixing agent (Commercial Fixer) according to the recipe. Temperature inwards this bathroom volition travel on at 40°C in addition to handling fourth dimension is 3-5 minutes. By this handling the stuff volition live treated equally endure colored. Most of the dye particles volition endure travel into into the inwardness of fibers in addition to the fiber volition swell at some extent thence that the pores of fibers volition live reduced in addition to dye materials cannot come upwards out from the innermost part. It volition increase the color fastness of the materials.
