Xiamen: Breaking the International Monopoly and Building a New Material Highland of Flash Evaporation

In the cutting-edge field of new materials innovation, Dangsheng New Materials Co., Ltd. in Haicang, Xiamen has made remarkable breakthroughs.Through relentless efforts, the company has successfully mastered the flash-vaporization method for specialty nonwovens—a crown jewel in the nonwoven industry—ultimately breaking the long-standing monopoly held by foreign giants in this field.

The flash evaporation technique is highly sophisticated, producing materials with a distinctive micro-fiber mesh structure that uniquely combines the lightweight of paper, the density of film, and the softness of fabric.The specialized materials developed through this technology not only exhibit exceptional strength and toughness, but also demonstrate outstanding waterproofing and breathability, achieving a balance in multiple critical performance metrics that traditional materials struggle to match.

What's more remarkable is that Sheng New Materials didn't just settle for catching up with others in technology.The R&D team has innovatively developed the world's first' in-situ dyeing' flash-evaporation nonwoven fabric.The technology achieves uniform and durable coloration by injecting dye during fiber formation, eliminating the need for subsequent dyeing processes.This not only simplifies the process, but also avoids the high water consumption and wastewater pollution caused by traditional dyeing and printing from the source, making it a model of green manufacturing.

The non-woven fabric industry in Fujian is no longer limited to traditional 'disposable' products, but is transitioning to high-value-added fields such as ultra-fine fibers, biodegradable materials, and special protective applications. With technological advancements, Shengxin Materials' production capacity is steadily expanding.The product range has expanded from its original focus on high-end medical protective suits and medical packaging to emerging markets including outdoor gear, premium cultural and creative products, fashion apparel, and specialized industrial materials, demonstrating vast application potential.This series of achievements signifies China's major leap from dependence on imports to independent innovation, and even leading development in the field of high-end nonwovens .
