"Нити утка" (duck threads) refer to the horizontal threads in a woven fabric. In textile terminology, these threads run perpendicular to the vertical threads, known as "нити основы" (warp threads). The combination of these two types of threads creates the fabric's structure and determines its strength and texture. In weaving, the balance between the нити утка and нити основы is crucial for the final product. Different materials can be used for both types of threads, affecting the fabric's appearance and durability. Common fabrics like cotton, linen, and silk utilize this technique to achieve various styles and uses.
