How to Achieve Zero Wastewater in High-Energy Disperse Digital Printing? - HONGSAM Washing-Free High-Energy Disperse Ink Has Been Launched

Abstract:

In response to the high-water consumption and heavy pollution that have long haunted the textile printing and dyeing industry, HONGSAM has introduced its Kyocera Washing-free High Energy Disperse Ink. This breakthrough technology completely eliminates the traditional “reduction washing” step in high-energy disperse printing, fundamentally restructuring the production process. It ends the long-standing dilemma of high-water use, high pollution, and high safety risks associated with washing, ushering the textile printing industry into a new era of zero wastewater discharge, high efficiency, and lower costs.

As a high-tech enterprise with over 20 years of deep expertise in digital inkjet printing, HONGSAM has consistently led the way in green printing and dyeing technology. In the field of high-energy disperse printing, HONGSAM is not only a technology developer, but also a key driver of industry standards. The launch of Kyocera Washing-free High Energy Disperse Ink marks HONGSAM’s successful solution to the decades-old “washing pollution” problem and fills a critical gap in domestic processing technology.

I. Industry Background: The Washing Dilemma in Traditional Printing and Dyeing

Although traditional high-energy disperse digital printing is widely used in the textile industry, it has always been constrained by one unavoidable process — reduction washing.

To remove unfixed dye, enhance color brightness, and improve color fastness, the conventional process requires massive amounts of precious water. According to the Printing and Dyeing Industry Specification Conditions (2023 Edition) issued by the Ministry of Industry and Information Technology, the fresh water intake for cotton, linen, chemical fiber, and blended woven fabrics must not exceed 1.4 tons per 100 meters. In an era of increasingly stringent water resource controls, the highly water-intensive reduction washing step has become a major “liability” restricting enterprise capacity and compliance.

Beyond excessive water consumption, reduction washing also drives up wastewater treatment costs and extends production cycles. Moreover, the use of hazardous chemicals such as sodium hydrosulfite (reducing agent) and caustic soda in the process creates significant safety risks for factories.

Faced with tightening environmental regulations and strong market demand for cost reduction and efficiency improvement, the industry urgently needs a real process revolution.

II. Core Technical Solution: High-Energy Disperse “Washing-Free” Technology

To address these pain points, HONGSAM has officially launched Kyocera Washing-free High Energy Disperse Ink. Through groundbreaking formulation and process optimization, this solution completely eliminates the washing step, achieving a dual breakthrough in efficiency and environmental protection.

The success of this solution stems from the deep integration of three core technologies:

ž Nano-level Color Paste Precision Control: The use of nano-dispersed dye pastes significantly improves dye penetration and fixation rate, greatly reducing the generation of unfixed dye from the source.

ž Specialized Ink Development: The high-energy disperse ink, developed specifically for Kyocera printheads in a washing-free process, ensures excellent jetting performance while substantially minimizing unfixed dye.

ž Dedicated Process Development: The supporting pre-treatment liquid DP-05 effectively solves the common problems of dull color and poor fastness typically associated with non-washed fabrics, meeting market demands for high-quality orders.

HONGSAM began R&D on high-energy disperse inks more than a decade ago, overcoming numerous technical challenges. It was among the first in China to launch and successfully apply such inks. In 2013, its disperse direct-printing dye inks were included in the seventh batch of the Recommended Catalogue of Advanced Energy-Saving and Emission-Reduction Technologies for China’s Printing and Dyeing Industry, gaining strong market recognition. Today, HONGSAM’s high-energy disperse inks have been successfully applied to printheads from Ricoh, Kyocera, StarFire, Epson, Konica Minolta, and others. With the new Washing-free High Energy Disperse Ink (Kyocera-specific), HONGSAM has broken through the long-standing technical barrier of balancing environmental protection with performance, achieving a green transformation in the printing process.

III. Product Advantages: Outstanding Performance Leading the Industry

The Kyocera Washing-free High Energy Disperse Ink is not only an environmental pioneer — it also delivers exceptional performance:

ž Superior Color Performance: The ink achieves color saturation comparable to traditionally washed fabrics. Printing is extremely smooth, with excellent vibrancy in large solid areas, gradients, and fine pattern details — nearly matching the results of reduction-washed materials.

ž High Color Fastness: Even without washing, dry and wet rubbing fastness, washing fastness, and light fastness all meet or exceed required standards.

ž Excellent Penetration: Compared with traditional heat transfer processes, this ink offers significantly better penetration into the fabric.

ž Natural Soft Hand Feel: The fabric retains its original soft hand feel, ensuring excellent wearing comfort.

ž Effective Solution to Staining Issues: For long-standing industry challenges such as staining on polyester brushed fabrics and milk silk, combining the ink with the dedicated ink provides an effective solution.

IV. Product Specifications and Application Guidelines

To ensure optimal production results, we provide detailed product specifications and recommended process parameters.

Basic Specifications：

Recommended Production Process

The fabric should first be treated with DP-05 pre-treatment liquid, dried, and then printed using HONGSAM Washing-free High Energy Disperse Ink along with the dedicated ink. Key parameters are as follows:

Application Range

This product is widely suitable for various polyester chemical fiber fabrics, including but not limited to: polyester brushed fabrics, ant cloth, milk silk, chiffon, satin, and similar materials.

Conclusion

“The birth of the high-energy disperse washing-free printing process marks a milestone in the textile printing and dyeing industry’s transition toward green and intelligent manufacturing.”

It not only simplifies the production process but also reduces costs, minimizes wastewater discharge, and eliminates the use of hazardous chemicals — giving enterprises stronger market competitiveness. HONGSAM warmly invites printing and dyeing companies to embrace this new technology, redefine high-energy disperse printing, and jointly usher in the “zero-washing” future of the industry.
