Name of the Experiment: Application of soil release finish to cotton fabric.

1. Objective:
To learn about soil release finish.
To learn about the process of finishing any fabric with soil release finish.

2. Theory:
Soil release finishing is the finish that allows stains to leave the fabric faster & makes fabric cleanable without significant loss of soil release properties.

3. Experimental Procedure:
Sample: 100% cotton knitted fabric.
Dyes & Chemicals:

Calculation:
                Total Liquor :                     Material Weight X L    
                                                                = 5gm X 40
                                                                = 200 mL

                                                               
               
                Finishing Agent :               =  (200 X 1)/(1% X 1000) mL   
                                                           =  20mL




                    Initial Water :                     = Total Liquor - (chemicals)
                                                                = 200-20 mL
                                                                = 180 mL

Process Description:
                At first, we need to collect 100% cotton knit fabric, then we have to treat the sample with soil release finishing agent at 50°C for 25 minutes. Then we dry the sample for assessment.  

Precautions:
o   Taking chemicals as per recipe provided by the Instructor.
o   Taking every weight of chemicals carefully.



Sample Attachment:









                                               
Result & Discussion: We observe here the cotton knitted sample well finished with soil release finishing agent.



6. Conclusion & Comments: By doing this experiment we have learned about finishing process of any fabric by soil release finish.
