In 2012, we had a break thorogh on the zero pullotion dyeing method after we study jointly with semi government body and university.
In 2015 we built a medium size and a industrial size phototype machine to prepare for the similation of commercial production. We also find out colour fastness, satuation, and colour pantone.
In 2018 we went into a mass yarn dyeing trial and successed in colour fastness and satuation. We also optimize parts of the machine and its process method ready to commercialise production.
