A yarn coating agent may contain: a water dispersible polyurethane resin which comprises 2-4 wt% of N-methyldiethanolamine and 68-70 wt% of water, and has 25-29 wt% of aliphatic isocyanate polyol and 0.4-1% of triethylamine as a chain extender; a thickener which comprises 26-32 wt% of an alkali copolymer compound, 1-3 wt% of alkali polyoxyethylene sodium sulfate, 0.001-0.2 wt% of potassium sulfate, and water; and distribution water. Coating with the polyurethane resin gives an effect of not using an organic solvent. In addition, the uniformly coated polyurethane resin gives a beautiful effect on the yarn and fabric. 본 발명은 원사 코팅제에 있어서 지방족 이소시아네이트 폴리올 25 내지 29 중량%, 트리에칠아민 0.4 내지 1중량%를 쇄연장제로 사용하고, N-메칠디에탄올아민 2 내지 4 중량% 및 물 68 내지 70중량%를 혼합한 수분산성 폴리우레탄 수지와; 알칼리계 공중합체화합물 26 내지 32중량%, 알칼리계 폴리옥시에틸렌 황산나트륨 1 내지 3중량%, 황산칼륨 0.001 내지 0.2중량% 및 물을 잔부로 혼합한 증점제와; 분산수를 혼합하여 제조되는 것을 기술적 요지로 한다. 폴리우레탄 수지를 코팅시 유기용제를 사용하지 않는 효과를 제공한다. 또한, 폴리우레탄 수지가 균일하게 코팅되어 원사 및 원단이 미려한 효과를 제공한다.
