Sustainable Yarn Dyeing Machine Supplier in China for 1:7 Liquor Ratio Hank Dyeing Equipment

Shin Tong Yunn is a sustainable yarn dyeing machine supplier in China providing 1:7 liquor ratio equipment with pneumatic air cylinder safety covers, focusing on hank yarn dyeing machines, including SH normal-temperature spray hank yarn dyeing machines and GSH high-temperature high-pressure spray hank yarn dyeing machines. These machines are designed for dyehouses that need efficient hank yarn dyeing, stable color results, lower water consumption and safer daily operation.

In hank yarn dyeing, water consumption, steam usage, dyeing uniformity and operator safety are closely related to machine structure. A practical sustainable dyeing solution should not only reduce liquor volume, but also ensure sufficient spray circulation, stable temperature control, suitable hank loading and reliable machine operation.

The 1:7 liquor ratio is especially meaningful for SH and GSH series spray hank yarn dyeing machines. Under suitable yarn loading and process conditions, this liquor ratio helps reduce the amount of water, steam, dyestuff auxiliaries and wastewater generated in each dyeing batch. Actual consumption still depends on yarn material, hank size, loading rate, shade depth and dyeing process.

SH and GSH Series Hank Yarn Dyeing Machines

Shin Tong Yunn supplies two main types of spray hank yarn dyeing machines for different dyeing temperatures and yarn materials. The SH series is designed for normal-temperature dyeing, while the GSH series is designed for high-temperature and high-pressure dyeing. If you are not sure which machine type fits your yarn, you can also review our hank yarn dyeing machine application guide before model selection.

Series	Machine Type	Typical Application	Dyeing Temperature
SH Series	Normal-temperature spray hank yarn dyeing machine	Cotton, wool, acrylic, viscose, silk, hemp and blended hank yarn	Atmospheric dyeing, usually below 100℃
GSH Series	High-temperature high-pressure spray hank yarn dyeing machine	Polyester, synthetic fiber and polyester blended hank yarn	High-temperature dyeing, designed for synthetic yarn processes

Both series use spray circulation to dye hank yarn in a loose and gentle form. Compared with traditional high-liquor hank dyeing methods, a properly designed spray hank yarn dyeing machine can reduce water consumption while helping maintain level dyeing and good yarn hand feel.

Why 1:7 Liquor Ratio Matters for Hank Yarn Dyeing

Hank yarn dyeing usually requires enough liquor to wet, circulate and penetrate the yarn evenly. However, excessive liquor volume increases water usage, heating demand, chemical consumption and wastewater discharge. The 1:7 liquor ratio design of SH and GSH series machines helps dyehouses balance resource saving and dyeing performance.

Production Factor	Benefit of 1:7 Liquor Ratio Design
Water Consumption	Reduces the water volume required for each hank yarn dyeing batch under suitable loading conditions.
Steam Consumption	Less liquor volume requires less heat energy during heating and temperature holding.
Dyeing Auxiliaries	Lower bath volume can help reduce auxiliary chemical dosage according to the recipe.
Wastewater Volume	Reduces wastewater discharge and helps lower pressure on the effluent treatment system.
Production Cost	Supports long-term cost reduction through lower water, steam and chemical consumption.

The liquor ratio should not be treated as a single isolated number. For hank yarn dyeing, the final result also depends on spray pipe arrangement, pump flow, yarn hanging density, nozzle design, temperature control and operator experience. Shin Tong Yunn designs the machine structure according to the real hank yarn type and production requirement.

Spray Dyeing Structure for Better Hank Yarn Handling

SH and GSH series machines use spray circulation to deliver dye liquor evenly through the hank yarn. The spray system helps improve liquor contact with the yarn surface and reduces the risk of yarn compression that may occur in some tightly loaded dyeing methods.

For hank yarn, gentle handling is important because the yarn is dyed in an open skein form. The machine should support even wetting, smooth circulation and stable dye penetration without excessive mechanical stress. This is especially important for wool, acrylic, cotton, polyester blended yarn, carpet yarn and other hank yarn applications.

Key point: A sustainable hank yarn dyeing machine is not only about a lower liquor ratio. It must also provide stable spray circulation, suitable hank loading and repeatable dyeing performance.

Pneumatic Air Cylinder Safety Covers for Easier Operation

The pneumatic air cylinder safety cover is an important practical feature for SH and GSH series hank yarn dyeing machines. It assists cover opening and closing, reduces manual labor and makes daily operation more convenient for dyehouse workers.

For larger-capacity machines, the cover can be heavy and frequent manual operation may increase labor intensity. The pneumatic air cylinder system helps operators handle the cover more smoothly, improving batch preparation efficiency and workplace safety.

For high-temperature GSH series machines, safety should be considered together with pressure vessel design, pressure control, safety valve, temperature control, operating procedure and cover structure. The pneumatic cover system improves operation convenience, while the complete safety design supports reliable production.

Typical Model Range for SH and GSH Hank Dyeing Machines

Shin Tong Yunn can supply different capacities according to laboratory sampling, small-batch production, medium dyeing orders and large-scale hank yarn dyeing production. The final capacity depends on hank yarn size, yarn type, loading method and required production plan.

Application	Recommended Series	Suitable Production Use
Cotton Hank Yarn	SH Series	Normal-temperature reactive dyeing and common hank yarn production.
Wool or Acrylic Hank Yarn	SH Series	Gentle spray dyeing for yarns that require controlled handling and stable color results.
Polyester Hank Yarn	GSH Series	High-temperature dyeing for polyester and synthetic yarn processes.
Polyester Blended Hank Yarn	GSH Series or selected process design	Selected according to material composition, dyeing temperature and process requirement.

For small-lot polyester hank yarn, sample development or shade approval, customers can also check the GSH-1-60 5kg high temperature spray hank yarn dyeing machine. It is designed for high-temperature hank yarn dyeing where compact capacity, process testing and flexible small-batch production are required.

Customization According to Yarn and Factory Requirements

Different dyehouses have different hank yarn sizes, yarn materials, batch weights and color production plans. Before recommending a machine, Shin Tong Yunn usually confirms the yarn material, hank size, single hank weight, batch capacity, dyeing temperature, steam condition, voltage, control preference and factory layout.

• SH series for normal-temperature spray hank yarn dyeing.
• GSH series for high-temperature high-pressure spray hank yarn dyeing.
• 1:7 liquor ratio design under suitable loading and process conditions.
• Pneumatic air cylinder safety cover for easier cover operation.
• Semi-automatic or fully automatic control system available.
• Steam heating as common configuration; electric heating can be discussed for small or special machines.
• Machine capacity can be selected according to sampling, small-batch or bulk production needs.
• Voltage and electrical configuration can be arranged according to destination country requirements.

How SH and GSH Machines Support Sustainable Dyeing

For dyehouses, sustainability must be practical. A machine that reduces water but causes uneven dyeing or frequent reprocessing does not truly save cost. SH and GSH series machines are designed to support lower water consumption while maintaining stable dyeing performance through suitable spray circulation and process control.

With a 1:7 liquor ratio design, the dyehouse can reduce the amount of water heated and discharged in each batch. This helps lower steam usage, reduce wastewater volume and improve overall operating efficiency. At the same time, stable spray circulation helps the yarn absorb dye more evenly, reducing the risk of color difference and re-dyeing.

Important Note

The actual liquor ratio, water saving and energy saving depend on yarn material, loading quantity, hank arrangement, dyeing process, shade depth and factory operation. Shin Tong Yunn recommends selecting the machine based on real production data rather than only comparing a single parameter.
