Accumulation Vessel
Vertical storage enclosure in continuous textile bleaching lines allows wet fabric ropes to accumulate, providing necessary reaction time for chemical processing. In J box rope storage, continuous fabric enters through a top piler mechanism and travels downward through an upright chute before curving upward at the exit curve. This geometry holds large textile quantities within a compact footprint while preserving continuous web processing speeds.
Maintaining proper filling height in the vertical chute guarantees uniform chemical dwell time for desizing and scouring agents.
Material Transport
Mechanical plaiters swing back and forth across the top opening to distribute fabric rope evenly across the vessel width. Even distribution prevents channel formation, ensuring processing steam penetrates the entire textile mass equally. Saturated fabric settles under its own weight, sliding toward the lower curve where exit rolls pull the rope outward.
Excessive packing density in J box rope storage causes deep pressure creases and mechanical friction against vessel walls. Adjustable liquor lubrication along the chute surfaces reduces friction, allowing heavy cotton wovens to slide smoothly without snags. Variable-speed extraction rollers synchronize fabric removal with upstream feeding mechanisms to maintain steady dwell times.
Chemical Action
Alkaline scouring chemicals require elevated heat and extended dwell time to saponify natural wax and pectin contaminants in raw cotton. Steam injection nozzles lined along the storage chute maintain high temperatures throughout the accumulated fabric stack. Uniform heat distribution prevents patchy absorbency before subsequent dyeing operations.
Density Verification
Operational checks track fabric rope weight against vessel volume to monitor accumulation rates. Line operators adjust drive speeds when density variations threaten fabric movement. Consistent processing speeds ensure predictable bleaching results across large production lots.
