| abstract |
The present invention may provide a method for high fastness dyeing of a fibrous yarn employing UV curing, wherein, in the method, yarns from general clothing fibers to industrial flame-retardant fibers are dipped in a UV-curable coating liquid to form a thin coating layer thereon, and then the UV-curable coating liquid is cured, and wherein the method not only provides an eco-friendly preparing method, which has an energy reduction rate of about 90% compared with an existing method of thermally curing and coating yarns; causes no wastewater due to the non-use of a medium such as water; has no emission of carbon dioxide by combustion; and can skip a washing process through a high degree of conversion, but also gives various performances by dispersing various functional materials with excellent adhesive strength. |
