Description

technical field

[0001] The present invention relates to a wound dressing sheet comprising natural or regenerated cellulose fibers comprising partially protonated carboxymethylcellulose (hereinafter abbreviated as CMC). More specifically, the present invention relates to a wound dressing sheet containing natural or regenerated cellulose fibers containing CMC capable of maintaining high liquid absorption and maintaining shape stability even after liquid absorption. Background technique

[0002] When a wound occurs on the human skin or the like, wound site protection materials such as surgical dressings and wound dressing materials that protect the site of the wound are used.

[0003] On the other hand, the following Patent Document 1 describes a soluble wound-hemostatic cellulose fiber having a CMC substitution degree of 0.5 to less than 1.0, and also describes that CMC has a cell adhesion promoting action. In addition, the following Patent Document 2 also describes that when...
