Which fabric is very elastic and adds stretch when blended, resistant to oils and outdoor elements, but shrinks and can be damaged by heat?

Which fabric is very elastic and adds stretch when blended, resistant to oils and outdoor elements, but shrinks and can be damaged by heat?

• A. Flannel
• B. Knit
• C. Spandex
• D. Polar Fleece

Answer: (C)

This item hinges on a fabric’s stretch and how it behaves with heat. Spandex is known for its exceptional elasticity and is added to blends to provide real stretch without losing shape. It also resists oils and holds up reasonably well in outdoor wear when blended with other fibers. But it’s heat-sensitive: high heat can shrink or damage spandex fibers. The other fabrics don’t deliver that strong combination of high stretch with the same heat sensitivity—flannel is not stretchy, a knit may have some give but isn’t defined by oil/outdoor resistance, and polar fleece is warm but not notably stretchy. So spandex best fits all parts of the description.
