The correct answer is
Nylon
Identifying the First Synthetic Fiber
The question asks to identify the very first synthetic fiber created by humans. Synthetic fibers are man-made materials produced from chemical compounds.
Understanding Nylon's Significance
Nylon is the correct answer because it holds the historical distinction of being the first fully synthetic fiber developed and commercialized by man. It was invented by Wallace Carothers at DuPont in the 1930s.
Evaluating Other Options
- Silicon: This is a metalloid element, not a fiber.
- Spandex: Although a synthetic fiber, it was developed much later than Nylon (invented in the 1950s).
- Acrylic: This synthetic fiber was also developed after Nylon, primarily in the mid-20th century.
Therefore, Nylon is recognized as the pioneer synthetic fiber.
