摘　　要：目的建立一种用藻酸盐齿科材料转印显现纺织物上血足迹的方法。方法依据藻酸盐能和纺织物上血足迹中的血结合,从而使足迹被转印到藻酸盐模上,并通过染色增强反差。结果藻酸盐印模材料转印法能够在不破坏织物客体的情况下清楚的反映出血足迹细节特征。结论藻酸盐类齿科材料能够转印、提取显现织物上血足迹,尤其是潜在血足迹,并反映出其细节特征。Objective To establish a method for lifting blood footprint on fabric.Methods The fabric with blood footprint was daubed with mixture of the alginate material and water,and then the lifted marks were enhanced using Acid Black 1.Results Impressed footwear marks deposited on fabric was lifted and the surface of fabric was not been damaged.Conclusion This lifting technique can be used for lifting blood impressions on fabric.
