An absorbable spun, cotton-like topical hemostat containing fibers entangled with each other and being made of atelcollagen obtained by reconstituting solubilized collagen. Each of the fibers has a diameter of 10 to 70 &mgr;m and a length of 3 to 70 mn. At least a part of the collagen molecules constituting the fibers are crosslinked by heat at a temperature of 50° to 200° C. The hemostat is swellable upon contact with blood. In use, the hemostat readily adapts to the shape of the hemorrhagic site, has an adhesiveness to a bleeding surface and provides an effective suppression of hemorrhage.
