    Given Information:
    - Reactive dye applied on cotton fabric by continuous method
    - Shade achieved on fabric is 2% on the weight of fabric
    - Dyebath concentration is 25 gram per litre
    - % expression after padding is 100
    - Specific gravity of the solution is 1

    To find:
    The fixation % of the dye on the fabric

    Solution:
    Step 1: Calculation of the amount of dye applied
    The shade achieved on the fabric is 2% on the weight of the fabric.
    Let's assume the weight of the fabric is 100 grams.
    Therefore, the shade achieved on the fabric = (2/100) * 100 = 2 grams

    Step 2: Calculation of the amount of dye in the dyebath
    The dyebath concentration is given as 25 grams per litre.
    Let's assume the volume of the dyebath solution is 1 litre.
    Therefore, the amount of dye in the dyebath = 25 grams

    Step 3: Calculation of the amount of dye fixed on the fabric
    The % expression after padding is given as 100.
    Therefore, the amount of dye fixed on the fabric = (100/100) * 2 grams = 2 grams

    Step 4: Calculation of the fixation % of the dye on the fabric
    The specific gravity of the solution is given as 1. This means that 1 litre of the solution weighs 1000 grams.
    Therefore, the amount of dye fixed on the fabric in terms of dyebath concentration = (2 grams / 25 grams) * 1000 = 80 grams

    The fixation % of the dye on the fabric = (amount of dye fixed on the fabric / amount of dye in the dyebath) * 100
    = (80 grams / 1000 grams) * 100 = 8%

    Therefore, the fixation % of the dye on the fabric is 80%.

    Explanation:
    The fixation % of the dye on the fabric is calculated by comparing the amount of dye fixed on the fabric to the amount of dye in the dyebath. In this case, the shade achieved on the fabric is 2% on the weight of the fabric, which means that 2 grams of dye is present on 100 grams of fabric. The dyebath concentration is given as 25 grams per litre, and assuming a volume of 1 litre, the amount of dye in the dyebath is 25 grams. The % expression after padding is 100, indicating that all the dye applied to the fabric has been fixed. By comparing the amount of dye fixed on the fabric (2 grams) to the amount of dye in the dyebath (25 grams), and considering the specific gravity of the solution, the fixation % of the dye on the fabric is calculated to be 80%.

    Shade%=2%
    Therefore we can consider that 2kg of dye is present in 100kg of fabric
    Dyebath conc=25gpl (25g dye present in 1L of solution)
    Specific Gravity=1 (Denotes 1L=1kg)
    Padding Expression = 100 (100L of dye soln uptake)
    If 1L of solution contains 25g dye, then
    100L of solution contains = (25/1000)*100kg = 2.5kg dye

    Fixation% = (Amt of dye in fabric/Amt of dye in liquor)*100
    =(2/2.5)*100 = 80%
