response: Speaking of synthetic fibers, I know that those are made with chemical synthesis, did you know that ?
original_response: One good thing about synthetic fibers is that they are not made from animals, mostly derived from fibers.
history: I really enjoyed wearing Cardigan sweaters in the fall or winter.  I think it adds a bit of sophistication to a person's wardrobe. Nice that you enjoyed that, do you prefer the ones that are machine or hand-knetted? I prefer the knitted ones, my mom use to make cardigans for women Speaking of cardigans for women, did you know that Coco Chanel is the one credited with popularizing that ? I didn't know that, I always prefer wool cardigans, but the can now be made with cotton or synthetic fibers too
knowledge: Synthetic fibers (British English: synthetic fibres) are fibers made by humans with chemical synthesis, as opposed to natural fibers that humans get from living organisms with little or no chemical changes.
