Progressive Electrolyte Metering Schedules for Low Liquor Jet Dyeing Heavy Duck
Progressive electrolyte metering controls reactive dye strike rates on heavy duck canvas in low liquor jets, preventing unlevelness and core shading defects.
Plaiting Mechanics
Fabric Stacking
Oscillating mechanical arms situated at the discharge end of fabric transport tubes fold running fabric ropes into neat layers inside dye vessel storage chambers. Plaiting mechanics controls the back-and-forth laying movement, preventing fabric tangling and ensuring smooth rope withdrawal during continuous circulation. Mechanical link arms or motor-driven swivels direct fabric movement across vessel width, building structured folds in the storage basket.
Proper folding action allows maximum fabric capacity while preventing local tension buildup during high-speed dyeing operations.
Fold Geometry
Uniform stroke length and stroke speed determine how evenly fabric ropes stack inside liquid-filled vessel bottoms. Irregular plaiting causes fabric ropes to pile into localized heaps, leading to circulation stoppages and pressure marks on fabric surfaces. Modern machines use speed-synchronized plaiter drives linked directly to main reel rotation speed.
Precise coordination maintains uniform fold density and prevents fabric compaction under its own wet weight.
Tension Elimination
Smooth fabric deposition inside storage baskets eliminates longitudinal tension while goods soak in heated dye liquor. Unrestricted relaxation allows synthetic fibers to shrink uniformly, preventing permanent heat-set creases and rope marks. Well-plaited fabric moves smoothly toward the winch reel without snagging or dragging against vessel side walls.
Vessel Storage
Basket design works together with mechanical plaiters to support heavy fabric loads without causing mechanical abrasion. Automated sensors detect uneven stack heights, adjusting plaiter arm stroke angles to preserve free rope movement throughout dye cycles.
