Which of the following refers to horizontal fibers in fabric, also known as weft or filling?

The term that refers to horizontal fibers in fabric, also known as weft or filling, is "woof." In the context of weaving, woof describes the threads that run perpendicular to the warp threads, which are the vertical fibers. This structure is foundational in textile manufacturing because the combination of warp and woof creates a woven fabric, contributing to its strength and texture.

Understanding the roles of warp and woof is essential for anyone involved in apparel and accessories marketing, as it helps in assessing fabric quality, understanding garment construction, and making informed decisions regarding textiles used in products. The relationship between these fibers ultimately influences the fabric's drape, durability, and overall appearance, which are critical factors in consumer satisfaction and marketing.
