The most interesting part of the fabric lab to me was the fact that all of the synthetic fabrics melted during the fire test.  I never thought about it before this lab, but that proves that all of the synthetic materials we tested were formed from some type of plastic.  I didn’t know what I thought they were made out of before, but now I really think about what I’m wearing based on whether it’s natural or synthetic.  Determining whether the fabrics were knitted or woven proved to be easier than I originally thought.  Nylon and rayon were knitted and both are synthetic.  Cotton, wool, and Polyester were woven, and cotton and wool are natural while polyester is synthetic.  The most difficult/confusing part of this lab was the whole section about the filament numbers.  There was not a clear explanation as to what that specifically meant, so when the chart had a section for filament count I was not sure what to write down.  Another thing I found interesting was that the natural fabrics held more water than the synthetic fabrics.  Perhaps this is because the natural fabrics are made of more coarse fibers, therefore, they can hold more water.  Lastly, this was kind of a pain, but it was cool to observe, the H2SO4 broke down the nylon.  The nylon practically disintegrated in the test and it was very difficult to remove the fabric from the container it was in.  I found this interesting because I would expect this solution to break apart all of the plastic-based fabrics (all of the synthetic ones), but it only broke down the nylon.  I think this is because the nylon has the most porous design, since the sample we used was from a pennie worn during a gym class.  This breathable aspect caused there to be more holes than any other fabric, which I believe caused the nylon to break down more easily.
