천의 종류와 두께에 따른 혈액의 세탁 정도에 관한 연구

초록

When washing fabrics with blood on them, it is important to know the factors that affect the washingcharacteristics of blood. To investigate this, the authors prepared different thickness fabrics of 100% cotton, cotton/polyesterblend(65%/35%), cotton/polyester blend(35%/65%), and 100% polyester. The cloths were then contaminated with blood,washed with detergent, and visualized with acidic hydrogen peroxide(a blood sensitive reagent) to observe the amount of bloodretained. The results showed that the blood washed out better with more washing cycles, and the blood washed out better witha lower percentage of cotton. However, regardless of the blend, the thickness of the fabric did not seem to have anycorrelation with the degree of blood washing. On the other hand, if the fabric surface was coated, the blood washed well.
