eight loss% can be defined as percentage decay in a material or parentage process loss of that material after the completion of a process. We did this experiment through a enzymatic process of same and different concentration for accordingly same and different structured knit fabrics. So due to same chemical action, attacking performance is not same due to different structured knit fabrics. Knit fabrics' surface is not same due to different structure or looping mechanisms. We have worked with enzymes and silicon softener as our main chemical agents. Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. The enzyme is used to form a reaction intermediate, but when this reacts with another reactant the enzyme reforms weight loss% is increased proportionally with the amount of enzyme used for the same period of time and vise-versa [3]. The The amount of enzyme present in a reaction is measured by the activity it catalyzes. The relationship between activity and concentration is affected by many factors such as temperature, pH, etc. An enzyme assay must be designed so that the observed activity is proportional to the amount of enzyme present in order that the enzyme concentration is the only limiting factor
1. Firstly we considered 3 types of knit fabrics of different lots namely Lycra Pique, Plain Rib (1x1) & Interlock. 2. Then, for the first lot of Lycra Pique we found 12.5% weight loss% due to the action of Enzyme wash (1%) and then treated with silicon softener (1%). 3. Afterwards we found 11.03% and 7.3% loss for Plain Rib (1x1) & Interlock respectively for the same chemical actions.
4. Now we decided to change the chemical concentration % of Enzyme solution by twice compared to before. 5. Then we found the weight loss% with a significant value. We thought may be the result of weight loss% can be twice compared to previous but the result was not that. 6. It was found that weight loss was 16.02% for lycra pique. 7. Following the methods, we found 14.9% and 8.6%
for Plain Rib (1x1) &Interlock respectively. 8. We used the following formula for calculating weight loss % : Weight Loss %=(Previous gray weight-Present weight) x100/ Previous gray weight.
Result & Discussion
In our composite factories, process loss% is considered same even for different structured knit fabrics. As a result problems may be arisen during maintaining accurate supply chain management. Our experimental data is an important guideline for the industries to calculate process loss% for considering not the common knit fabric issues but structural differences in the fabrics which have a significant impact on process loss%.
