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.

The SF-HT400 is purpose-built for dye houses specializing in polyester-cotton workwear fabrics, school uniform textiles, polyester sports and activewear, blended shirting and suiting materials, and home textile fabrics where high color fastness and durability are critical performance requirements. The high-temperature capability also makes it suitable for sublimation-fastness-critical automotive and outdoor textile applications.
