Which material is made from chemicals and is heat sensitive?

• A. Manufactured fibers
• B. Natural fibers
• C. Plant fibers
• D. Silk fibers

Answer: (A)

Understanding fiber origins and how they react to heat is what this item is about. Manufactured fibers are created from chemicals through polymerization and other chemical processes, so they are synthetic. Because they’re made from polymers, many of these fibers melt, fuse, or become distorted when exposed to heat, even at relatively low ironing temperatures. That’s what makes them heat sensitive. Natural fibers, plant fibers, and silk come from natural sources and tend to burn or char rather than melt, and their heat reactions differ from those of synthetic fibers. So the material that fits both clues—made from chemicals and heat sensitive—is manufactured fibers.
