DOBBY LOOM Meaning and
Definition
-
A dobby loom is a specific type of weaving machine or loom that incorporates a dobby mechanism for producing intricate and complex patterns in woven fabrics. The term "dobby" refers to the mechanical system used to raise and lower specific warp threads during the weaving process, allowing for the creation of various designs, motifs, or patterns on the fabric.
Unlike a conventional or plain loom, which maintains a straightforward interlacing of warp and weft threads, a dobby loom utilizes a series of pegs or hooks called "dobby bars" that act as controllers for manipulating the warp threads. These dobby bars may be dressed with various combinations of pegs, which correspond to specific groups of warp threads that need to be raised or lowered in order to form the desired pattern. By changing the arrangement of the pegs on the dobby bars, weavers can achieve an almost infinite range of complex patterns, including geometric shapes, floral designs, or intricate textures.
The construction of a dobby loom often involves a mechanical dobby mechanism, which can be operated manually, semi-automatically, or automatically, depending on the loom's design and functionalities. Dobby looms are widely used in the textile industry for creating high-quality fabrics with intricate designs, including upholstery fabrics, damasks, brocades, and intricate tapestries. The flexibility and versatility of dobby looms make them suitable for both small-scale handweaving and large-scale industrial production, enabling weavers to achieve intricate and precise patterns with ease.
Etymology of DOBBY LOOM
The term "dobby loom" originated from the combination of two words: "dobby" and "loom".
The word "loom" has Old English roots, deriving from the Old English word "geloma" or "healdian". It refers to a device or machine used for weaving fabric by interlacing threads at right angles. The Old English term was later transformed into the Middle English word "lome" and eventually evolved into "loom" as we know it today.
The term "dobby" traces its etymology back to the Dobby or Dobby Harness, which was named after its inventor, a French mechanic named Joseph-Marie Jacquard. In the early 19th century, Jacquard invented a mechanical device that allowed for intricate patterns to be woven into fabric. This device was named the "Jacquard loom" and utilized a system of punched cards to control the weaving process.
