The present invention relates to a method for producing a calcium carboxymethyl cellulose fiber by direct spinning of sodium carboxymethyl cellulose. According to the present invention, it is possible to provide a calcium carboxymethyl cellulose fiber which compensates for the disadvantages related to energy cost and environmental pollution, and which has both the wound-healing ability due to high absorption and gelation performance of carboxymethyl cellulose (CMC) and the hemostatic effect due to release of calcium ions (Ca^2+), wherein the calcium carboxymethyl cellulose fiber can be used as a wound dressing material, a hemostatic material, an anti-adhesion agent, and the like. 본 발명은 sodium-Carboxymethylcellulose를 직접방사공정에 의해 Calcium-Carboxymethylcellulose 섬유를 제조하는 방법으로서 본 발명에 의하면, 에너지비용과 환경오염의 단점을 보완하고 CMC의 높은 흡수성과 겔화 성능에 의한 상처치유능과 Ca2+ 방출에 의한 지혈효과를 동시에 가지는 창상피복재(Wound Dressing), 지혈재, 유착방지제 등으로 사용될 수 있는 Calcium-CarboxyMethylCellulose 섬유를 제공한다.
