Multi-Colour Weft Dobby Fabric Production
topic
Multi-colour weft dobby fabrics use two to four weft colours inserted in a programmed sequence coordinated with the dobby lifting programme to create colour patterns where specific weft colours appear on the fabric face in the areas programmed to the weave structures that expose that weft colour, with electronic dobby enabling simultaneous control of both shed selection and weft colour selection in the integrated loom control system that coordinates both variables per pick.
Role
Extends dobby fabric design capability into colour-patterned fabrics where the combination of programmed shaft selection and weft colour sequence creates colour pattern effects that geometric monochromatic dobby weaving cannot achieve, providing a lower-cost alternative to Jacquard for colour-pattern fabrics whose design repeat width is within shaft count capability, serving markets for checked and striped colour fabric designs that require weft colour variation beyond single-shuttle production.
