Mastering the Core: Key Logic for Efficient Operation of Overflow Jet Fabric Dyeing Machines

 

Exceptional performance of overflow jet fabric dyeing machine is rooted in deep understanding and precise control of several core operational principles. This article aims to clarify these key points, providing clear guidance for dyeing technicians and offering professional perspective for equipment selection and evaluation.

 

Core 1: The Starting Point of Precision — Nozzle Selection

The nozzle is the "heart" of this fabric dyeing machine. Correct selection is fundamental for smooth start to the dyeing process.

 

Structure is the Foundation: High-quality overflow jet fabric dyeing equipment nozzle typically features multi-layer annular design. Inner ring gap creates high-speed dye liquor jet that provides the core traction, while the outer flow-guiding ring stabilizes the direction, minimizing fabric flutter and creasing risks. Flange connection design allows for easy disassembly and thorough cleaning, a practical feature that ensures long-term stability and prevents clogging.

 

 

Selection Follows Logic: The core principle for choosing the nozzle specification (inner diameter) is clear: it must be larger than the rope-folded diameter of the fabric in its wet state. This ensures the fabric passes smoothly through dye stream, avoiding permanent creases from squeezing or poor circulation from insufficient traction. A well-designed machine should offer a range of nozzle options with clear selection guidelines to accommodate fabrics from lightweight to heavy.

 

Fabric Type	Typical Examples	Recommended Nozzle Diameter	Reasons for Selection
Lightweight (50-150g/m²)	Imitation silk, Chiffon, Taffeta	Φ50mm (or smaller)	A small-diameter, concentrated liquid flow prevents lightweight fabrics from slipping or folding inside the nozzle, avoiding "wrap-around" or crow's-foot marks. Paired with a narrow slit jet orifice (slit width 0.8-1.2mm), it is suitable for ultra-lightweight fabrics under 50g/m².
Medium-weight (150-400g/m²)	Gabardine, T/C Blends, Fleece	Φ60mm - Φ70mm	Φ60mm suits 150-200g/m² fabrics; Φ70mm suits 200-400g/m² fabrics. This balances dye liquor flow rate and velocity, ensuring even dye penetration while meeting both anti-creasing and anti-stretching requirements.
Heavyweight (400g/m² and above)	Canvas, Terry Cloth, Imitation Leather	Φ100mm or larger	Increases flow area and reduces liquid flow velocity, preventing heavy fabrics from being squeezed and forming stubborn creases at the nozzle, and reducing the risk of motor overload.

 

Core 2: The Soul of Synchronized Operation — Balancing Lifting Wheel and Nozzle Pressure

Soul of dyeing quality and efficiency lies in the synergy between cloth lifting wheel (mechanical traction) and the nozzle pressure (liquid traction). Achieving dynamic balance between them is the most crucial operational skill.

 

Consequences of Imbalance: If the lifting wheel runs too fast with insufficient dye jet traction, the fabric becomes overstretched, leading to deformation, weft skew or even breakage. Conversely, if the wheel is too slow, the fabric can pile up and fold under the jet impact, creating hard-to-remove "chicken paw" marks or uneven dyeing, potentially causing blockage.

 

Logic and Goal of Adjustment: Proper adjustment is a process of "observe, judge and coordinate." Operator must assess the fabric state (taut or piled) through the viewport and adjust accordingly, following the principle of "adjust the lifting wheel speed in the opposite direction, then coordinate nozzle pressure." For example, if the wheel is too fast, slow it down; if the fabric remains tense, slightly increase nozzle pressure by 0.2-0.5 bar to enhance the liquor's "lifting force." The ultimate goal is to achieve an ideal state where the fabric flows naturally suspended and smoothly inside the tube. For multi-tube machines, ensuring load difference not exceeding 10% between tubes is key to preventing "tube difference" and ensuring color consistency.

 

Note:

When using the double-end feeding process for lightweight fabric, setting lifting wheel speed to 500 meters per minute enables conventional two-tube fabric dyeing machine to process a batch of up to 4000 meters in single cycle. This approach significantly boosts production efficiency while maintaining high dyeing quality.

Key Operational Steps for Double-End Feeding:

1. Low-Speed Feeding & Tension Control: The feeding process must begin in a low-speed mode. It is crucial to maintain strictly consistent tension between the two fabric strands. This ensures smooth and even entry into fabric dyeing machine, preventing issues where one strand feeds faster, slower, tighter or looser than the other.

2. Stable Circulation Before Dyeing: After the fabric ends are joined (knotted or sewn), continue running the machine at a low speed for approximately 10 minutes. This critical step verifies that both fabric strands are circulating steadily and without tangles or pile-ups. Only after confirming this stable flow should you proceed with subsequent dyeing steps like heating, pressurizing and adding chemical.

 

 

Core 3: The Guarantee of Consistent Output — Process Details and Standardization

Beyond core balance, standardized control of detailed processes is the cornerstone of reproducible results batch after batch.

 

Process Refinement: Dyeing is not static. For instance, during the high-temperature phase (130-140°C) for polyester, nozzle pressure should be adjusted based on fabric weight: 0.3-0.5 bar for lightweight fabrics, 1.2-1.5 bar for heavy fabrics. Circulation and balance must be maintained during heating and cooling phases, and rapid cooling from high temperatures is strictly avoided to prevent thermal shock creases.

 

Operation Standardization: This includes unit consistency and maintenance discipline. Confusion between pressure units (bar, MPa, psi) is a major risk. Details like clear multi-unit markings on pressure gauges and unified units in process documents reflect the quality of professional modern fabric dyeing equipment. Furthermore, disassembling and cleaning the nozzle after each batch is the simplest yet most effective maintenance to preserve flow design and jet performance.

Conversion formula

1 bar = 14.5038 psi = 0.1 MPa

1 MPa = 10 bar = 145.038 psi

1 psi ≈ 0.06895 bar ≈ 0.006895 MPa

 

Fabric Type	Nozzle Pressure (bar)	Corresponding Pressure (MPa)	Corresponding Pressure (psi)	Key Process Application Points
Lightweight Fabrics	0.3-0.6	0.03-0.06	4.35-8.70	Low-pressure penetration to avoid pilling or creasing caused by high-pressure impact, maintaining the fabric's lightweight hand feel
Regular/Elastic Fabrics	1.0-1.5	0.1-0.15	14.50-21.75	Enhances dye liquor exchange rate, ensures uniform dye penetration, and overcomes circulation resistance in elastic fabrics.
Heavyweight Fabrics	1.5-2.5	0.15-0.25	21.75-36.26	Strong liquid flow forcibly penetrates high-weight fabrics to prevent uneven dyeing and ensure consistent color between the inner and outer layers

 

Future Perspective: Pathways to Enhanced Efficiency

Currently, overflow jet dyeing technology is evolving towards greater intelligence and sustainability. Real-time parameter monitoring via IoT sensors and process optimization using algorithms promise to increase dyeing reproducibility to over 98.5%. Meanwhile, adopting high-efficiency pumps, heat recovery systems, and low liquor ratio (as low as 1:5) designs can significantly reduce water, energy, and chemical consumption. These trends are becoming important factors in evaluating the long-term value of new-generation fabric dyeing equipment.

Fabric specification calculation is a core process linking design, production and trading. For fabric designers, it provides scientific basis，guiding factory production; For sales department, it is an essential tool for client communication, quotation and cost control. Mastering this skill, being able to quickly calculate product cost, provide accurate & timely quote and  identify key cost factors precisely. Within entire fabric preparation workflow, dyeing process as one of the critical step affecting fabric quality and specification, influences the accuracy of all calculation parameters directly.

 

Link Between Raw Material Quantity Calculation and Dyeing Process

First step of fabric specification calculation is determining raw material quantity, which involves various process shrinkage rate, such as fiber shrinkage, twist shrinkage and weaving shrinkage. Many of these are closely related to dyeing and finishing process. For example:

 

Raw Material Shrinkage: Different fibers behave differently during dyeing. Cellulosic fiber like cotton, linen or viscose, may have shrinkage about 2% after dyeing or bleaching, while synthetic fiber like polyester filament is significantly affected by heat-setting processes.

 

Dyeing and Finishing Shrinkage: The ratio between greige fabric length and finished fabric length, directly determined by dyeing and finishing processes. Stable dyeing process effectively controls shrinkage variation, ensuring fabric weight, width and other related specifications meet design expectation.

 

If temperature, tension or time is not controlled properly during dyeing, shrinkage rate can deviate from expectation. It affects whole batch's material calculation, leading to cost errors or quality issues. This is precisely why textile manufacturers need high-performance, controllable yarn and fabric dyeing equipment to ensure process consistency.

 

Fabric Weight Calculation: Key Role of Dyeing and Finishing 

Formulas for calculating finished fabric weight per meter and GSM, refining weight loss ratio and dyeing & finishing shrinkage rate are two crucial variables. Refining weight loss ratio reflects weight loss of fibers during dyeing and finishing (e.g., ~75–80% for silk, ~99% for synthetics). Dyeing and finishing shrinkage rate is directly related to length change between greige and finished fabric.

 

This data is not only used to calculate weight but also forms basis for cost quotation. If dyeing stage is unstable, weight loss ratio and shrinkage rate will fluctuate. This can cause fabric weight to fall outside acceptable tolerances in mass production, impacting customer trust and profit margins directly. Therefore, investing in precise and repeatable yarn and fabric dyeing machinery is key to achieving standardized fabric specification.

 

How Dyeing Processes Affect Component Ratio Calculation in Multi-Fiber Fabric?

For blended or interwoven fabric, different fibers exhibit vastly different dyeing behaviors. For instance, when silk/linen blended yarn is interwoven with viscose yarn, the dye uptake, shrinkage and weight loss ratio must be precisely managed during dyeing due to their different fiber compositions. As shown in the example as below, calculating the percentage of each component relies on its specific weight loss ratio and process shrinkage. These parameters must remain stable throughout the dyeing process to ensure the final composition matches the design.

 

For fabrics woven or blended from two or more types of raw materials, it is essential to calculate the proportion of each material. The calculation method is as follows:

Content of Material A = (Weight of Material A × Proportion of Material A × Refining Yield of Material A) ÷ (Weight of Material A × Refining Yield of Material A + Weight of Material B × Refining Yield of Material B) × 100%

 

Example:

A product uses warp yarn of 120N/2 silk-linen blended yarn (70% silk, 30% linen) and weft yarn of 40S/2 bright rayon yarn.

Finished fabric width: 140 cm, plain weave

Finished warp density: 28 ends/cm, finished weft density: 24 picks/cm, greige fabric weft density: 23 picks/cm

 

Considering various factors, the estimated weaving shrinkage is about 5%, silk process shrinkage is 2.5%, weft width shrinkage is about 10%, and viscose staple fiber process shrinkage is 2.0%.

 

Warp yarn quantity (g/m) = Finished warp density × Finished fabric width × (1 + Process shrinkage) × (1 + Weaving shrinkage) × Yarn fineness ÷ 9000

= 28 × 140 × (1 + 5%) × 1/60

= 65 g/m

 

Weft yarn quantity (g/m) = Finished weft density × Finished fabric width × (1 + Weft weaving shrinkage) × (1 + Process shrinkage) × Yarn fineness ÷ 9000

= 140 × 24 × (1 + 10%) × 0.59/20

= 109 g/m

 

Finished fabric weight per meter (g/m) = (Warp yarn quantity × Refining yield + Weft yarn quantity × Refining yield) ÷ Dyeing and finishing shrinkage

= (65 × 0.95 + 109 × 0.97) ÷ 0.96

= (61.8 + 105.7) = 167.5 ≈ 168 g/m

 

Fabric weight per square meter (g/m²) = Weight per meter ÷ Fabric width

= 168 ÷ 1.4

= 120 g/m²

 

Among these:

Silk content = (Weight of silk component × Silk proportion × Silk refining yield) ÷ (Weight of silk component × Refining yield + Weight of rayon yarn × Refining yield)

= (65 × 0.7 × 0.95) ÷ (70 × 0.95 + 109 × 0.97) × 100%

= 43.2 ÷ 167.5 × 100%

= 26%

 

Linen content = (Weight of linen component × Linen proportion × Linen refining yield) ÷ (Weight of linen component × Refining yield + Weight of rayon yarn × Refining yield)

= (65 × 0.3 × 0.95 × 100%) ÷ (65 × 0.95 + 109 × 0.97)

= 18.5 ÷ 167.5 × 100%

= 11%

 

Rayon content = (Weight of rayon yarn × Rayon refining yield) ÷ (Weight of warp yarn × Refining yield + Weight of rayon yarn × Refining yield)

= (109 × 0.97 × 100%) ÷ (109 × 0.97 + 65 × 0.95)

= 105.73 ÷ 167.5 × 100%

= 63%

 

From the above calculations, warp yarn quantity of the product is 65 g/m and weft yarn quantity is 109 g/m. Based on this, adding a certain percentage of waste yarn according to the product process, combined with the market price of raw material, provides relatively accurate raw material cost. Adding weaving and dyeing processing costs shows the base price of product.

 

This requires consider select appropriate textile dyeing equipment. For example:

Yarn Dyeing Machine: Used for yarn-dyed fabrics, allowing pre-dyeing of warp or weft yarns to ensure color uniformity and shrinkage control.

Hank Dyeing Machine: Often used for yarns like wool or cotton that require gentle handling, better preserving yarn elasticity and hand-feel.

Fabric Dyeing Machine: Used for piece dyeing of finished fabrics (open-width or rope form), effectively controlling width and weight variation.
