Multi-Colour Weft Insertion Systems
topic
Multi-colour weft insertion for Jacquard figured fabrics uses rapier looms with 2 to 8 colour selectors, air-jet looms with tandem nozzle systems for 2 to 4 colours, and projectile looms with multiple shuttle boxes handling 4 to 8 weft colours, with the loom controller coordinating weft colour selection with the Jacquard lifting programme so that each colour carrier is inserted on the picks where its colour is required in the design, with colour selection occurring at defined picks determined by the design programme.
Role
Provides the weft colour variety required for multicolour figured Jacquard fabrics by enabling multiple yarn types to be inserted in the programmed sequence that creates colour-patterned figured fabrics, with the coordination between weft colour selection and Jacquard hook selection being the production system integration that translates multicolour design programme data into the physical weft colour distribution that creates the visible colour design in the woven fabric.
