THIN FILM COLOR COATING METHOD FOR HARD-TO-DYE YARN

摘要

The present invention relates to a thin film color coating method onto polychromatic fibers. The method includes the steps of: impregnating a thread made of polychromatic fibers into a UV radiation-curing coating solution; forming a thin-film coating layer; and curing the UV radiation-curing coating solution. The method of the present invention has about 70% of an energy saving rate compared to a conventional thermal curing method, prevents the discharge of carbon dioxide due to combustion, and is capable of omitting a washing process at a high degree of conversion, thereby being performed in an environmentally friendly manner. The method also ensures superior adhesion and disperses various functional substances to apply various functions to the thread.
