The report is divided into three parts. 

First, where does the momentum for market innovation come from? As the global economy continues to develop, the middle class is growing, their incomes are rising, and the demand for sustainable products is increasing. Additionally, it has been observed that consumers in interational metropolises like New York and Shanghai share similar consumption characteristics, necessitating the provision of products tailored to their preferences. Moreover, there is a heightened global emphasis on environmental protection, accompanied by demands for decarbonization and corresponding climate regulations. By 2050, it is anticipated that recycled textile fibers and regenerated cellulose fibers will account for more than half of the market share, while fossil-based textile fibers and natural fibers will become the minority.　

The second part of the report presents three case studies as path references. The ionic liquid process is similar to the lyocell production process, where the solvent recovery rate is the most significant factor affecting costs, with moderate raw material supply and process complexity. Recycling old clothing into pulp has the advantage of a large raw material supply, but currently, the collection and sorting infrastructure are inadequate, and the technical difficulty is higher. Lastly, the direct spinning method is simpler but has extremely high energy consumption.

The relevant technologies for new cellulose fibers are still in the early stages of development, and their production costs need to reach commercial levels in order to compete with existing fibers, with hopes of being lower than current products. How can companies implement these ideas? They need to clarify their technological pathways, integrate into interdisciplinary value chains, foster collaborative industry partnerships, develop raw material supply chains, and seek capital support.
