At that time the dye was taken from the animals and plants or minerals with little treatment. As for dye-sub printing, there are strict requirements to dye. The small directness, low affinity, and good diffusion As it will dry immediately after printing, there will be no problem of balance like  textile dyeing . Therefore, the dye-sub printing with small directness, low affinity, and good diffusion can be used directly. If use reactive dyes with a large directness, the reaction opportunities of active groups and fiber will increase, but t...
