Our eco-friendly L-shaped overflow dyeing machine for woven fabric adopts a unique integrated structure with three independent functional fabric storage tanks, setting a new benchmark for modern fabric dyeing equipment in the textile industry. Engineered with optimized structural integration, this innovative dyeing equipment perfectly merges the core strengths of two mainstream dye tank designs in the market.
Traditionally, O-type dyeing tanks feature a low liquor ratio that saves dye materials and reduces production costs, yet they are limited by narrow fabric compatibility and cannot meet the processing demands of diverse woven fabrics. In contrast, conventional L-shaped dyeing tanks support a wide spectrum of woven fabric types but suffer from excessive water consumption and poor environmental performance, failing to align with global green textile production standards.
Our upgraded L-shaped overflow dyeing machine effectively eliminates the inherent drawbacks of traditional dyeing equipment. By combining the low liquor ratio advantage of O-type dye tanks and the broad fabric adaptability of classic L-shaped structures, this eco-friendly dyeing machine delivers dual breakthroughs in production efficiency and environmental protection. It supports full-range woven fabric processing while significantly cutting water and energy consumption, making it an ideal high-efficiency, green upgrade solution for textile dyeing and finishing factories.
Working Principle
The core structure of the Eco Friendly Overflow Dyeing Machine for woven fabric includes a dye bath, a circulation pump, nozzles, a heat exchanger, and a control system. During the dyeing process, the dye liquor is drawn from the bottom of the dye bath by a centrifugal pump, heated by the heat exchanger, and then enters the overflow tank. When the overflow tank is full, the dye liquor overflows into the overflow pipe using the liquid level difference, simultaneously carrying the fabric into the dye bath, forming a reciprocating cycle.
The fabric remains relaxed throughout the process, effectively eliminating dyeing defects caused by wrinkles, and experiencing minimal tension. The dyed fabric is soft to the touch and has a uniform color.
Feature
Our modern Eco Friendly overflow Dyeing Machine for woven fabric adopts an advanced downward-traveling single-barrel dual-fabric structure with a slide-type tank design, delivering outstanding production flexibility, large loading capacity, and stable dyeing performance for textile finishing plants. Featuring a generous single-barrel diameter of Φ1108 and built-in dual fabric storage tanks paired with double nozzles, this innovative dyeing equipment greatly expands fabric holding volume and significantly boosts overall production output. The upgraded large-capacity structure shortens the production cycle and helps factories achieve faster ROI compared with traditional small-capacity dyeing machines.
Designed for ultra-wide fabric compatibility, the machine supports dual nozzle working modes to meet diverse dyeing requirements of different textile materials. When equipped with overflow nozzles, it maintains a working pressure of 0.5~1.0KG/cm², perfectly suited for elastic fabrics and textile materials that demand low-pressure and low-tension dyeing processes to protect fabric texture and elasticity. When switching to jet nozzles, the maximum working pressure can reach 3KG/cm², enabling stable and uniform dyeing for high-density fabrics and ultra-fine fiber textiles. All nozzles are fitted with a dual anti-rotation device to ensure consistent running stability.
Energy-saving and eco-friendly performance stand out as core advantages of this dyeing machine. Equipped with newly designed downhill wave plates and optimized cloth storage tank structures, the equipment achieves an ultra-low liquor ratio ranging from 1:5 to 1:6. This optimized liquid ratio effectively minimizes the consumption of water, steam, and chemical auxiliaries in every dyeing batch, realizing remarkable energy conservation and emission reduction effects while lowering overall production costs for textile manufacturers.
In terms of production efficiency and dyeing quality, the single-barrel double-tank structure greatly optimizes the fabric circulation system inside the dyeing chamber. It shortens fabric circulation time and increases dye liquor circulation frequency, realizing fast fabric feeding, rapid dyeing reaction, and efficient two-way fabric discharging. The overall workflow upgrade effectively improves daily production capacity while ensuring uniform color penetration, stable color fastness, and consistent dyeing quality for every batch of finished fabrics.
