The correct option is (b)
Explanation
Fabric production primarily involves two distinct processes: weaving and knitting. Weaving is the process of arranging two distinct sets of yarns or threads together at right angles to create a fabric.Statement-wise Analysis
- Statement 1 is Incorrect. The process involving the arrangement of a single yarn to make a piece of fabric is called Knitting (e.g., socks, sweaters). In contrast, weaving requires at least two sets of yarns: the longitudinal threads (warp) and the transverse threads (weft).
- Statement 2 is Correct. The weaving of fabric is performed on a device called a loom. The primary function of a loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads.
- Statement 3 is Incorrect. Looms are not exclusively hand-operated. They are classified into two types based on their power source: Handlooms (operated manually) and Power looms (operated by electric power). The industrial revolution significantly shifted production from handlooms to power looms.
Key Takeaway: The fundamental difference between weaving and knitting is that weaving involves interlacing two sets of yarns, whereas knitting involves interlocking loops of a single yarn.
