First Claim
Patent Images
1. A thin film color coating method for a hard-to-dye fiber yarn, comprising:
- preparing an ultraviolet ray hardening type coating liquid by mixing 0.9˜
10% by weight of dye, 30˜
89% by weight of ultraviolet ray hardening type monomer, 10˜
40% by weight of ultraviolet ray hardening type oligomer and 0.1˜
20% by weight of photo initiator;
impregnating the hard-to-dye fiber yarn in the ultraviolet ray hardening type coating liquid;
forming a thin film coating layer on the surface of the hard-to-dye fiber yarn by passing it through compression rollers with a constant pressure; and
hardening the ultraviolet ray hardening type coating liquid by irradiating an ultraviolet ray of a wavelength range of 260˜
395 nm in such a way to move the coated hard-to-dye fiber yarn in the vertical direction from the ground.

Abstract
Disclosed is 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 a good adhesion strength and various performances by dispersing various functional substances.
