Soft Flow Dyeing Machines

Soft flow machines are widely used in the textile industry for pre-treatment, dyeing, and post treatment of fabric. The process typically consumes about 35 to 40 % of a plant’s total steam and involves heating, holding and cooling steps.

Steam and cooling water are used in a common heat exchanger to heat or cool the liquor. Heat from dye liquor is often not effectively recovered as waste heat recovery systems are frequently bypassed due to choking issues, resulting in higher specific energy consumption.

Typical issues plants face in soft flow dyeing include
– Higher rates of rejection or reprocessing
– Extended batch times
– Higher energy and water consumption
– Reduced heat exchangers
