Abstract: The present invention relates to a highly liquid absorbent and hardly water-soluble carboxymethyl cellulose (CMC) foam, which absorbs body fluid or water, expands in volume when absorbing liquid, does not gelate, and maintains shape. The hardly water-soluble CMC foam prepared according to the preparation method of the present invention has remarkably superior liquid absorption property, shows large volume expansibility when absorbing liquid, does not gelate, and maintains shape. Therefore, a remarkably improved ability is shown when used as a hemostatic agent and a wound dressing. In addition, when the CMC foam is treated with a CMC powder dispersing liquid, the surface characteristics change, thereby preventing adhesion with the skin and improving liquid retention capability. Thus, it is possible to control the liquid absorption property thereof to meet the desired purpose.

Abstract translation: 本发明涉及吸收体液或水的高吸液性和几乎不溶于水的羧甲基纤维素（CMC）泡沫体，吸收液体时体积膨胀，不凝胶化，保持形状。 根据本发明的制备方法制备的几乎不溶于水的CMC泡沫体具有非常优异的液体吸收性能，在吸收液体时显示出大的体积膨胀性，不凝胶化并保持形状。 因此，当用作止血剂和伤口敷料时，显示出显着改善的能力。 另外，当用CMC粉末分散液处理CMC泡沫时，表面特性发生变化，从而防止与皮肤粘合并提高保液能力。 因此，可以控制其液体吸收性能以满足期望的目的。
