Which of the following fibers is hydrophilic?Question 9Answera.Polypropylene b.Polyesterc.Woold.Teflon (polytetrafluoroethylene or PTFE)e.acrylic
Solution
The hydrophilic fiber among the options given is wool. Hydrophilic means it has the ability to absorb water. Wool can absorb a high amount of water, and it also retains warmth when wet, which is why it's used for winter clothing. Other fibers like polypropylene, polyester, Teflon (PTFE), and acrylic are typically hydrophobic, meaning they repel water.
