Jean Lab

Conclusion:

In this lab we asked the question, what concentration of bleach is best to fade the color out of new denim material in 10 minutes without visible damage to the fabric? We found that the 25% concentration was the best to fade color without that much visible damage. The reason we picked 25% is because 100% and and 50% had extensive damage, and while 12.5% and 0% didn't suffer as much damage, they did not change the color either. The 25% concentration of bleach ranked a 4 in both color removal and fabric damage. Bleach is known to break down pigments, and this concentration broke the pigments down enough without causing excessive damage.

However, there could have been errors in this experiment, as the jean material were not always in the bleach solution for exactly 1 minute. There was no timer while doing this experiment, so the timing may not have been exact. Due to this error, I would recommend that when doing this lab in the future, we use a timer so that our data can be more accurate.

This lab was done to demonstrate and set an example of how future labs should be. It taught us how to do the different steps, and also taught us about how bleach affects jean material and how it breaks down the pigment. Based on my experience from this lab, I understood how to properly execute an experiment  and how to perform a lab correctly.
