Textile printing is an intricate process that relies heavily on the quality and performance of auxiliary chemicals, none more critical than the printing thickener. The thickener plays a fundamental role in defining the rheological properties of the printing paste, ensuring sharp contours, preventing bleeding, and facilitating optimal dye transfer onto the fabric. For reactive printing, which is widely used for cellulose fibers like cotton due to its excellent wash and light fastness properties, the choice of thickener is paramount. Reactive dyes chemically bond with the fiber, requiring precise application to achieve desired color depth and definition. A suboptimal thickener can lead to blurred prints, uneven color distribution, and significant waste.

Introducing Reactive Printing Thickener KR-708HE, a state-of-the-art solution designed to elevate the standards of reactive textile printing. This high-performance liquid thickener is specifically engineered for applications on pure cotton and a wide variety of other fabrics, compatible with both traditional rotary screen printing and flat screen printing techniques. Its unique formulation ensures consistent, reliable performance under typical reactive printing conditions.

KR-708HE presents as a milky white liquid, sometimes containing small brown granules, reflecting its sophisticated composition. It possesses anionic ionicity and performs optimally within a pH range of 7.0 to 8.5 (1% solution), aligning perfectly with the alkaline conditions often required for reactive dye fixation. The recommended dosage is typically around 5.0%, although this can be adjusted based on the specific fabric, design complexity, and desired viscosity. The thickener is readily soluble in water, including both RO water and standard tap water, simplifying paste preparation.

One of the most significant advantages of Reactive Printing Thickener KR-708HE is its performance superiority compared to traditional thickeners such as sodium alginate. KR-708HE exhibits significantly better salt and alkali resistance. Reactive printing pastes often contain high concentrations of alkali and salt, necessary for dye fixation. Many thickeners degrade or lose viscosity under these conditions, leading to poor print quality. KR-708HE maintains its strong thickening ability and stability even in challenging chemical environments, ensuring consistent paste rheology throughout the printing run.

Furthermore, the use of KR-708HE leads to a marked improvement in the color yield of reactive dyes. It promotes higher color value and brighter shades compared to pastes thickened with sodium alginate. This enhanced color yield translates directly into cost savings due to reduced dye consumption and improved visual appeal of the printed fabric. The thickener also facilitates good permeability, allowing for better penetration of the dye into the fibers, crucial for deep, rich colors and patterns with sharp outlines.

Formulation flexibility is another key benefit. KR-708HE can be used effectively on its own as the sole thickener in the printing paste. Alternatively, it can be blended with sodium alginate. When used in combination, KR-708HE can greatly improve the color depth and brightness achieved with the mixed paste, while simultaneously helping to reduce overall printing costs by allowing for optimization of the thickener blend.

Preparing the printing paste with KR-708HE is a straightforward process. A typical instruction involves adding the recommended amount (e.g., 20 kg) gradually into a specified volume of cold water (e.g., 380 liters), stirring slowly for a duration of 50-60 minutes until a uniform paste is achieved. Allowing the paste to swell for approximately 6 hours before use is recommended to ensure full hydration and optimal viscosity development. The application method once the paste is prepared is consistent with standard textile printing practices using viscous pastes, similar to those employing sodium alginate.

The effectiveness and efficiency offered by Reactive Printing Thickener KR-708HE make it an indispensable auxiliary for textile printers aiming for high-quality results and optimized production costs. Its robust performance under various conditions, combined with its ability to enhance dye utilization and print clarity, positions it as a leading choice in the market for reactive printing auxiliaries. Furthermore, its formulation is developed with environmental protection in mind, aligning with increasing industry demands for sustainable textile production practices.
