Problems solved by technology

Microfiber suede is mainly composed of polyurethane (PU) and nylon 6 (PA6). Through the development of dyeing technology, the dyeing performance of suede products on the market has been greatly improved, which solves the problem of ultrafine fiber suede that existed before. There are problems such as poor fiber dyeing depth, poor dyeing uniformity, and poor color fastness. However, for the majority of consumers to pursue fashion and individual requirements, there is no relevant product on the market that can meet this requirement. The existing suede leather preparation method There is still room to improve product grades and further enhance product competitiveness
