Rayon fibers are most similar to which natural fiber in terms of softness and strength?

1. Cotton

2. Wool

3. Silk

4. Flax

The correct answer is: Cotton

Rayon fibers are most similar to cotton in terms of softness and strength. This similarity arises from the manufacturing process of rayon, which involves the use of cellulose, a component also found in cotton. Both rayon and cotton exhibit a soft texture, making them comfortable to wear against the skin. They are also comparable in strength; while cotton is generally known for its durability, rayon maintains a degree of strength, especially when wet. In contrast, wool is known for its distinct texture and elastic properties, which sets it apart from the smooth hand of cotton or rayon. Silk, while also soft and luxurious, possesses different characteristics due to the protein-based structure of its fibers and tends to be weaker than both cotton and rayon. Flax, the source of linen, also differs significantly in both texture and strength characteristics, offering a coarser feel compared to the softness of rayon or cotton. Therefore, the strongest resemblance in softness and strength between rayon and natural fibers is found with cotton.
