Thin film color coating method for hard-to-dye yarn

The invention relates to a method for hardening an ultraviolet ray hardening type coating liquid after a thin film coating layer is formed by impregnating a yarn formed of hard-to-dye yarns in the ultraviolet ray hardening liquid, while providing an environment friendly manufacturing method wherein about 70% of an energy may be saved as compared with a conventional thermosetting method, and carbon dioxide from a combustion is not produced, and a water washing process may be omitted with the aid of a high degree of conversion, while providing thin film color coating method for hard-to-dye yarn with a good adhesion strength and various performances by dispersing various functional substances. 本发明涉及种把难染性纤维构成的丝含浸于紫外线硬化涂层液，从而形成薄膜涂层后，使紫外线硬化涂层液硬化的方法，相对于以往的热硬化方式，具有约70％节能率，由于燃烧时不排放二氧化碳、高转化率，可省略水洗工序，使得不仅能够提供环保型制造方法，而且可以提供难染性纤维的薄膜彩色涂层方法，该涂层方法具有优秀的粘合力，能够通过分散各种功能性物质，来赋予各种性能。
