Thermal transfer printing of polyester fabric
Polyester fabric Polyester, that is, polyester fiber, is a chemical synthetic fiber. As an important variety in textile fiber, polyester fiber is widely used in apparel fabrics and industrial products. Because of its excellent shape-setting properties, the polyester yarn or polyester fabric has a flat, fluffy shape or pleats formed by shaping, and can remain unchanged even after repeated washing during use. Polyester printing mesh generally uses disperse dyes and thermal transfer printing technology. Disperse dye Disperse dyes are classified according to application properties and can be classified into low temperature type (E type), high temperature type (S type) and medium temperature type (SE type). Due to the requirement of pure polyester fabric printing, disperse dyes have certain sublimation fastness. The dye with too low sublimation fastness will stain the white ground during hot melt fixation, and the dye with low fixation rate will be smeared on the sur...
