What type of silk is derived from long, smooth fibers from unbroken cocoons?

Reeled silk is produced from long, continuous threads that are spun from the cocoons of silkworms. This type of silk is particularly valued because it retains the natural sheen and strength of the fibers. The process of reeling involves unwinding the silk fibers from the cocoon without breaking them, resulting in a smooth and lustrous material. This high-quality silk is often used in luxurious textiles and fashion items due to its desirable qualities.

The other types of silk mentioned do not offer the same characteristics. Combed silk refers to fibers that have been processed to remove shorter strands and impurities but does not specifically indicate that the fibers come from unbroken cocoons. Synthetic silk is a man-made alternative created from polymer fibers, which lacks the natural properties of true silk derived from silkworms. Textured silk may involve various processes to create a different feel or appearance but does not relate specifically to the derivation of long, smooth fibers from unbroken cocoons.
