ECERDYE SF-HT400 140C High Temperature Soft Flow Dyeing Machine with 400kg Capacity for Polyester Cotton Blended Fabrics
The ECERDYE SF-HT400 is a specialized high-temperature soft flow dyeing machine engineered to operate continuously at temperatures up to 140°C, making it the ideal choice for polyester, polyester-cotton blended, and other synthetic fiber textiles that require high-temperature disperse dyeing processes. With a 400kg capacity, this machine delivers efficient and reliable high-temperature dyeing performance for demanding production environments.
The SF-HT400 is built around a robust pressure vessel rated for continuous operation at 140°C and 0.45 MPa working pressure. The high-temperature capability is essential for achieving optimal dye exhaustion and color fastness on polyester and polyester-blend fabrics using disperse dyes. The thermal oil circulation heating system provides even heat distribution throughout the dyeing chamber, eliminating hot spots that can cause uneven dye uptake. A heating rate of 6°C/min ensures rapid cycle times without thermal shock to sensitive fabrics.
Processing polyester-cotton blended fabrics presents unique challenges requiring both high-temperature capability for the polyester component and gentle handling for the cotton component. The SF-HT400 addresses this with a specialized dyeing program library featuring optimized temperature profiles, hold times, and chemical dosing sequences for PC, CVC, and TC blend ratios. The machine supports both one-bath and two-bath dyeing methods for polyester-cotton blends, giving operators full flexibility in process design.
The 400kg capacity is optimized for rapid heating and cooling cycles, with the triple-layer ceramic fiber insulation system minimizing heat loss and reducing energy consumption by approximately 20% compared to conventional insulation methods. The high-pressure overflow nozzle maintains gentle fabric transport even under high-temperature conditions, preventing fabric damage while ensuring thorough liquor penetration for level dyeing results.
