The weft yarn is treated with alkali before entering the jet dyeing device 2 to keep the water content at 20%, and the rest steps are the same as those of the example 1.
Example 7
The weft yarn is subjected to alkali treatment before entering the jet dyeing device 2, the water content is kept at 45%, and the rest steps are the same as those of the example 1.
The invention can combine the weft yarn dyeing process and the weaving process to form a process, and weaves while dyeing, thereby saving the cost required by the process and avoiding the problem of unmatched progress of the warp and weft yarns. The invention arranges the spray dyeing device 2 and the drying device 3 between the weft yarn frame 1 and the weft accumulator 4, and does not need to modify weaving equipment. The invention adopts the spray dyeing mode to dye the weft yarns, controls the spraying of the dye liquor by controlling the spraying state of the air flow, realizes the continuous or discontinuous spray dyeing of the weft yarns, is suitable for the dyeing of most warp yarn varieties and has high dyeing speed.
