Introduction

The textile printing industry, historically characterised by resource-intensive wet processing and substantial environmental influence, faces unprecedented pressure to decarbonise and digitise. Conventional reactive dye printing typically consumes 100–150 litres of water per kilogram of printed fabric and generates effluent containing heavy metals, residual dyes and auxiliary chemicals [1]. Regulatory frameworks including the EU Green Deal, China's ‘dual carbon’ targets and evolving corporate sustainability mandates have rendered traditional production modalities economically untenable for an increasing proportion of market participants [2]. Pigment-based digital inkjet printing has emerged as a technically viable and commercially scalable alternative, offering elimination of water-intensive washing and steaming stages, reduced energy consumption and enhanced production flexibility [3].

However, historical limitations in colour fastness, hand feel and process reliability have constrained market penetration, particularly in premium textile segments.

Zhengzhou Hongsam Digital Science and Technology Co, Ltd – founded in 2001 and designated a National High-tech Enterprise since 2003 – has systematically addressed these technical barriers through sustained investment in materials science, formulation chemistry and process engineering. This paper analyses Hongsam's technological architecture, commercial deployment patterns and service infrastructure to elucidate the mechanisms underlying its competitive positioning in international markets.

1. Core technological innovation: The Jetextile® textile pigment ink platform

1.1 Formulation architecture and environmental compliance

The Jetextile^® textile pigment ink series represents Hongsam's principal technological achievement, developed through proprietary nanoscale aqueous processing techniques. The formulation achieves complete aqueous carrier systems without organic solvent content, thereby minimising volatile organic compound (VOC) emissions throughout the product lifecycle. Independent certification includes the OEKO-TEX Eco Passport, REACH compliance and Global Organic Textile Standard (GOTS) accreditation, satisfying the most stringent requirements of international brand owners and regulatory authorities.

Intellectual property protection encompasses four national invention patents awarded between 2006 and present, with the technology recognised by the China National Textile and Apparel Council (CNTAC) through the 2022 Excellent Patent Silver Award and inclusion in the China Dyeing and Printing Association Energy-Saving and Emission-Reduction Advanced Technology Recommendation Catalogue (2016).

1.2 Performance characteristics

Technical evaluation of the Jetextile^® platform reveals six interconnected competitive advantages that collectively enable industrial-scale deployment:

Substrate versatility. The pigment-based chemistry exhibits compatibility with cellulosic fibres (cotton, linen), protein fibres (silk, wool), synthetic fibres (polyester, polyamide), and blended constructions across woven, knitted and nonwoven architectures. This universality reduces technical complexity for multi-product manufacturing environments and supports mass-customisation business models.

Process streamlining. Production cycle compression represents a critical operational benefit. Conventional reactive printing requires 7–9 discrete stages: pretreatment (sizing), printing, drying, steaming, washing, soaping and final drying. The Jetextile^®-enabled process reduces this to three core operations: optional pretreatment, printing and fixation, achieving cycle time reductions exceeding 70% and enabling linear production flow compatible with digital manufacturing execution systems.

Resource efficiency. Quantified environmental performance demonstrates water consumption reduction of ≥95%, energy reduction of ≥50%, and chemical usage reduction of ≥60% relative to conventional reactive processes. The elimination of aqueous effluent generation removes the capital and operating burden of wastewater treatment infrastructure, particularly significant for facilities in water-stressed regions or jurisdictions with stringent discharge regulations.

Economic optimisation. Cost structure advantages manifest across multiple dimensions: reduced capital investment requirements for entry-level system configurations; diminished utility consumption (water, electricity, steam); simplified quality control protocols due to reduced process variability; and elimination of environmental compliance expenditures associated with effluent management. Digital production planning systems further amplify these advantages through precise cost attribution and continuous optimisation.

Reproducibility and quality consistency. The direct digital workflow eliminates variability sources inherent in analogue processes (screen engraving, paste preparation, colour matching). Reduced sensitivity to environmental conditions (temperature, humidity, water quality) ensures batch-to-batch and sample-to-production colour consistency essential for data-driven quality management and digital twin implementation. First-grade yield improvements directly enhance economic returns.

Durability performance. Advanced binder chemistry and optimised pigment dispersion achieve light fastness ratings of 6–7 (ISO 105-B02) and excellent chlorine bleach resistance, satisfying requirements for outdoor textiles, home furnishings and technical applications previously considered exclusive to reactive dye systems.

2. Integrated product portfolio and process solutions

Hongsam's "HONGSAM+" operational philosophy encompasses a comprehensive product ecosystem extending beyond core ink formulations to encompass pretreatment agents, post-treatment chemistries and application-specific process protocols. Table 1 presents the systematic product architecture organised by printing methodology.

Note: K = Black, C = Cyan, M = Magenta, Y = Yellow, HY = High-Yield Yellow, R = Red, G = Green, B = Blue, OR = Orange, V = Violet, VM = Vivid Magenta, GY = Gray, LC = Light Cyan, LM = Light Magenta, OP = Opaque, CO = Coating, W = White, FM = Fluorescent Magenta, FY = Fluorescent Yellow. Dilution ratios indicate pretreatment agent-to-water proportions.

The product architecture demonstrates systematic coverage of principal industrial printing modalities.

DTF (direct-to-fabric) roll-to-roll (piece goods fabric) printing configurations address high-volume fabric production, with graduated pretreatment concentration ranges (PP-01/PP-03 at standard dilution versus PP-17 at extended dilution up to 1:100) enabling optimisation for diverse substrate characteristics and performance requirements. Post-treatment agent selection (PA-03/PA-04 for standard applications; PA-05 at elevated dilution for specialised finishes) provides corresponding flexibility in final product attributes.

DTG (direct-to-garment) printing employs simplified pretreatment protocols (PP-05 as ready-to-use solution; PP-08 as directly applicable paste) reflecting the distinct handling characteristics of pre-cut garment components versus continuous fabric rolls.

DTF (direct-to-film) heat transfer modality eliminates pretreatment and post-treatment stages entirely, representing the most streamlined process architecture within the portfolio. The optional powder-free formulation addresses evolving regulatory and operational preferences regarding particulate handling.

Since 2016, Hongsam has progressively developed integrated processing solutions that unify ink, pretreatment, and post-treatment chemistries within coherent technical systems. The Rapid Colour Technology (RCT) protocol, subsequently extended to include in-line sizing processes and the JETALL^® water-based latex ink platform, exemplifies this systems-level approach.

2.1 JETALL^® water-based latex ink platform

The JETALL^® system, recognised in the 16th China Dyeing and Printing Association Energy-Saving and Emission-Reduction Advanced Technology Recommendation Catalogue (2023), enables aqueous inkjet printing on non-absorbent and hydrophobic substrates—including synthetic leather, technical textiles and coated materials – previously requiring solvent-based or UV-curable systems. This capability expansion addresses a significant market gap in sustainable digital printing for high-performance and technical textile applications.
