[Key Product No. 03 from Zhongfang Chemical] The “Quality‑Driven Power” Hidden in Every Drop of Sizing: Zhongfang Sizing Agents Make Every Printing Job Shine Brighter

2026-07-01

Printing paste is not merely a carrier for dyes; it is a core material that ensures the stable operation of the printing process and the quality of the final product. It directly influences the rheological properties of the color paste, the apparent color yield on the fabric, the sharpness of pattern outlines, the uniformity of penetration across the fabric surface, and the hand feel of the finished goods, serving as a technological link between equipment, dyes, processes, and fabrics.

　　Market Status Quo: Issues Becoming Evident

　　• Strong reliance on raw materials and significant cost volatility

　　Frequent fluctuations in raw material prices have led to an unstable cost structure for printing and dyeing enterprises.

　　• The substitute product’s inadequate performance constrains overall quality.

　　Modified natural thickeners and synthetic thickeners produce prints with darker hues and reduced color vibrancy, resulting in a stiff hand feel and a rough fabric surface—conditions that fail to meet high-end customers’ demands for comfort and softness.

　　• Printing quality standards have been raised, and traditional techniques can no longer meet the demands.

　　Conventional pasting agents struggle to meet the stringent requirements of crisp pattern outlines, uniform and consistent fabric penetration, no color floating, no printing defects, and no paste seepage—particularly in double-sided printing and permeation processes, where balancing pattern clarity with adequate penetration proves especially challenging.

For more than a decade, Zhongfang Chemical has focused on printing pastes. Leveraging a robust technological platform and extensive industry expertise, the company has addressed the key challenges of “difficult-to-print, costly printing, and high waste,” offering dyeing and printing enterprises an efficient, stable, and environmentally friendly one-stop printing solution that helps them achieve simultaneous improvements in quality, cost reduction, and environmental sustainability.

 

　　01 Reactive Printing Paste

　　Triple stability ensures exceptional printing performance.

　　• Salt resistance: The viscosity of the color paste decreases by less than 5% after 48 hours, with excellent color stability.

　　• Temperature resistance: After 48 hours at a constant temperature of 60°C, the viscosity reduction is less than 10%, and the adhesive layer remains intact.

　　• Sulfur resistance: After 24 hours of exposure to printing paste, the viscosity drop is less than 5%, ensuring accurate pattern reproduction.

 

　　02 Acidic Printing Paste HL-S200 Series

　　A star product, designed specifically to tackle tough challenges.

　　• Easy to remove: thoroughly removes paste, leaving a soft feel.

　　• Deep color: 1.5–2 times better than sodium alginate

　　• Solves common printing defects: eliminates issues such as pinholes, surface slurry, and blurred patterns all at once.
