Which term indicates the unraveling of threads?

• A. Ausfransung
• B. Reibkorrosion
• C. Fehler
• D. Kleberauflösen

Answer: (A)

The term that indicates the unraveling of threads is indeed "Ausfransung." This term comes from the context of textiles and materials, where it describes the fraying or splitting of fibers, leading to the visible threads that seem to unravel from the fabric. The concept is commonly encountered in sewing, fabric care, and materials science, where maintaining the integrity of the threads is essential to the durability of the material.

In contrast, the other terms relate to different concepts. "Reibkorrosion" specifically refers to wear or corrosion due to friction, typically in mechanical contexts. "Fehler" is a general term meaning "error" or "fault," which does not have a direct connection to the physical process of threads unraveling. Lastly, "Kleberauflösen" translates to "adhesive dissolving," indicating a process involving glue or bonding agents separating, which is also unrelated to thread fraying. Thus, "Ausfransung" accurately captures the essence of threads unraveling in fabric and textiles.
