Which type of yarn is identified as more durable and holds a crease well?

Worsted wool is known for its durability and ability to hold a crease well because of its unique spinning process. In making worsted wool, the fibers are long and aligned parallel to each other, which creates a smooth and strong yarn. This method not only enhances the durability of the fabric produced but also allows it to maintain its shape and crispness, making it ideal for tailored garments and items where a structured look is desired.

In contrast, carded wool involves a less refined spinning process where shorter fibers can be used, resulting in a softer but less durable texture. Spun wool typically refers to yarn created by twisting together shorter fibers, which also does not offer the same level of strength or crease retention as worsted wool. Textured yarns often have a more casual or relaxed appearance and generally prioritize softness or stretch over durability and shape retention. Hence, the characteristics of worsted wool make it the best choice among the given options for durability and crease holding.
