In the rapidly evolving world of digital textile printing, the success of an ink formulation hinges on the sophisticated interplay of its components. At the heart of high-performance inkjet inks lies the binder—a critical chemical additive that dictates the ink's adhesion, durability, and printability. NINGBO INNO PHARMCHEM CO.,LTD., as a specialized manufacturer and supplier, offers advanced polyurethane binders, providing key solutions for chemists and formulators in this dynamic industry.


Our expertise lies in understanding the complex chemistry required for optimal ink performance. The polyurethane binders we develop feature unique pre-polymer segments, incorporating specialized graft diols, polymeric diols, and acid-containing diols. These are then connected by innovative chain extenders, specifically polymerized sulfonate-containing diamines. This precise molecular architecture is what grants our binders their exceptional properties, allowing for superior interaction with both colorants and various fabric substrates.


A primary focus in ink formulation for digital textile printing is achieving a delicate balance between jettability and durability. Our binders ensure excellent jettability, which translates to stable drop formation, minimal nozzle clogging, and consistent print quality over extended periods. This is crucial for high-volume industrial printers. Concurrently, the binders impart remarkable washfastness and enhanced durability in textile printing, ensuring that printed fabrics withstand rigorous use and washing cycles without degradation. When you need to purchase polyurethane binder for demanding ink formulations, our products offer proven results.


The acid number and particle size of the binder dispersion are meticulously controlled parameters that influence the overall ink stability and performance. Our polyurethane binder dispersions are characterized by specific particle sizes (e.g., as low as 27 nm) and acid numbers, optimized for stable pigment dispersion and efficient curing. This precision is vital for creating inks suitable for Direct-to-Garment (DTG) and Direct-to-Fabric (DTF) applications where performance consistency is paramount. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted polyurethane binder supplier committed to supporting your ink development.


By understanding the nuances of chemical additives like our modified acrylic polyurethane dispersion for fabric, formulators can unlock new levels of performance. Our technical team is dedicated to collaborating with R&D departments to fine-tune formulations, ensuring that our binders contribute to inks that are not only technologically advanced but also commercially successful.
