In the chemical fiber and nonwoven industries, the dispersion quality of color masterbatch directly determines the quality of the fiber. To address issues like fiber breakage, flying fibers, and color difference common in ultrafine fiber production using traditional dry processes, Yancheng Ruize Color Masterbatch Co., Ltd. (hereinafter referred to as "Ruize") has developed a new solution for quality enhancement based on its independently developed wet ultrafine grinding and nano-dispersion coating technologies.

According to Ruize's technical team, the company uses six wet grinding production lines to refine pigment particles to the nanometer scale. A special coating process then ensures their uniform and stable dispersion within the polypropylene matrix. This technological breakthrough allows Ruize's polypropylene masterbatch to be used in the production of ultrafine fibers with a fineness as low as 0.25 denier, demonstrating excellent stability on advanced nonwoven equipment like the German Reicofil IV.

"Our polypropylene masterbatch not only offers pure color but, more importantly, solves pain points for our downstream customers during high-speed spinning," said a Ruize representative. "Stable dispersion means a lower fiber breakage rate and more uniform product performance, which directly improves our customers' production efficiency and product yield."

Currently, Ruize's polypropylene masterbatch serves globally renowned companies such as JOFO, PGI, and TORAY, and is widely used in high-end fields including medical and health, automotive interiors, and marine engineering. With 36 advanced twin-screw extrusion production lines, the company has an annual capacity of 15,000 tons, providing global customers with a stable and reliable product supply.

In the future, Ruize will continue to deepen its wet grinding core technology, promote the development of polypropylene masterbatches towards greater refinement and functionality, drive product upgrades through technological innovation, and help downstream customers gain an advantage in the fierce market competition.
