Well, you're on the right track. While the Kotex would begin by absorbing blood, if one were to keep it in the same position, placing pressure or tightly taping it on, the blood would clot fairly quickly depending on some other factors, i.e. the blood clotting status of the victim (aspirin, coumadin, etc could increase bleed times), size of the wound, etc.
In an emergency, they're a good resource. But then, so are cob webs. If a nice wad of them can be found and placed on the wound, they act as clotters and will help to eliminate or at least slow the bleeding. John
