In the dynamic world of textile manufacturing, achieving vibrant colors, sharp patterns, and a superior fabric finish is paramount. Reactive printing is a cornerstone technique for cotton and other cellulosic fibers, known for producing brilliant hues with excellent wash fastness. A critical component in this process is the printing thickener, which controls paste viscosity, ensures precise pattern application, and influences the final feel of the fabric. NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce Reactive Printing Thickener KR-708, a high-performance auxiliary designed to elevate the standards of reactive textile printing.

Reactive Printing Thickener KR-708 is presented as a milky white viscous emulsion, specifically formulated for use in reactive dye printing pastes. Its primary function is to provide the optimal rheology required for successful screen or roller printing, ensuring the paste transfers cleanly and stays within the defined pattern area without bleeding. Beyond mere thickening, KR-708 offers a suite of properties that contribute significantly to both process efficiency and the quality of the final printed textile.

One of the standout characteristics of KR-708 is its contribution to achieving a high color value and bright colors. By ensuring proper dye fixation and minimal migration during steaming and washing, the thickener helps in the full realization of the dye's potential, resulting in prints that are vivid and striking. The prints exhibit a clear shape with excellent comprehensive properties, including superior permeability and leveling. This means the dye paste penetrates the fabric surface evenly, and the print lines are sharp and well-defined.

Efficiency in the print shop is boosted by the fact that KR-708 is rapid in preparing paste. It disperses and hydrates quickly, forming a stable printing paste without requiring extensive mixing time. This paste remains steady over time, maintaining its viscosity and flow characteristics, which is crucial for consistent printing quality across large production runs and minimizes waste due to paste degradation.

A highly valued property is the high rate of destarch. This refers to how easily the thickener is removed from the fabric during post-printing washing processes. A high destarch rate translates to faster, more efficient washing, reducing water and energy consumption. More importantly, it contributes directly to the fabric's soft handle. Residual thickener can leave fabric stiff or harsh; efficient removal ensures the textile retains its natural softness, which is highly desirable for consumer comfort and product appeal.

Furthermore, KR-708 demonstrates excellent net penetration and leveling, combined with good flow performance. This is vital for achieving uniform color depth and preventing mottling or patchy prints, especially on challenging fabric structures or with fine screens. The rheological profile ensures the paste flows smoothly through the screen mesh or roller gaps while maintaining its structure on the fabric surface until fixation occurs.

Technical specifications for Reactive Printing Thickener KR-708 highlight its suitability for various applications. It is an Anionic product with a pH value typically ranging from 6.0 to 7.0 in a 1% solution, compatible with the slightly alkaline conditions often required for reactive dye fixation (usually achieved by adding sodium bicarbonate to the paste). The recommended dosage generally falls within the range of 4.5% to 5.0%, though this can be adjusted based on the specific printing process, fabric type, screen mesh, and desired paste viscosity. It is formulated to work effectively with both RO water and tap water, offering flexibility in paste preparation.

The compatibility of KR-708 with other common auxiliaries in reactive printing pastes, such as sodium alginate (which it can be used in conjunction with), reactive dye, sodium bicarbonate, resist salt, and sodium hexametaphosphate, underscores its versatility and ease of integration into existing printing formulations. Its very good anti-electrolyte performance ensures the paste viscosity remains stable even in the presence of electrolytes contributed by dyes and other chemicals.
