Significant progress has been made in the research project of recyclable marine components

Compared with non fixed island island fiber, fixed island fiber has advantages in both physical properties and environmental impact. However, the sea component widely used in fixed island fiber is alkali soluble polyester chips (i.e. COPET chips), which still require the use of sodium hydroxide and salt (sulfur) acid in reduction and sewage treatment processes, and will form solid waste, which will still have adverse effects on the environment. If the island component is PET, there is still a risk of damage to the island component by alkaline solution and the flame retardant components being destroyed.

To address this issue, the company has collaborated with research institutions to develop recyclable sea components as an alternative to COPET slicing, and significant progress has been made in this work. The processes of slicing synthesis, spinning, non-woven fabric, impregnation, reduction, post-processing, and marine component recovery have been fully integrated, laying the foundation for industrial mass production.

At present, both parties are cooperating with downstream leather companies to conduct detailed and comprehensive process verification on subsequent steps such as impregnation and reduction. They hope to develop a full process environmentally friendly microfiber leather using recyclable marine components and water-based resins that is more cost-effective than existing products, and contribute to environmental protection and the transformation and upgrading of the leather industry.
