The effect of the damage type and the damage level on the canges in surface characteristics of keratin fibers was studied. Then, we investigated the relationships between the change in surface characteristics and that in water transport behavior along damaged keratin fibers. For this purpose, human hair fibers were damaged by two means : chlorination of the hair with DCCA reagent, and physical treatment, namely, rubbing the fibers with sandpaper. We prepared several samples differing in the level of damage by each method. Surface morphology of damaged fibers were examined by light and scanning electron microscopy (LM and SEM), and chemical structures of the surfaces were evaluated by amino acid analysis. We confirmed that the surface characterization results reflect the type and level of damoges. Contact angle (rheta) values were evaluated for damaged fibers by measuring the wetting force of a single fiber sample using the Wilhelmy-type apparatus. The averaged values of rheta for damaged fibers decreased upon the degree of damage. We investigated the water transport behavior along variously damaged human hair fibers using the electrical capacitance technique which has been reported by us (2). The results show that the rate of water trasport along fiber bundle was strongly influenced by the type and level of damage to keratin fibers.

研究了损伤类型和损伤程度对角蛋白纤维表面特性变化的影响。然后，我们研究了表面特性的变化和水运输行为之间的关系，沿着受损角蛋白纤维。为此，人发纤维被两种方法损伤：用DCCA试剂氯化的头发，和物理处理，即用砂纸摩擦纤维。我们准备了几个样品，每种方法的损伤程度不同。通过光学显微镜和扫描电子显微镜（LM和SEM）检查受损纤维的表面形态，并通过氨基酸分析评估表面的化学结构。我们证实，表面表征结果反映了Damoges的类型和水平。通过使用Wilhelmy型装置测量单个纤维样品的润湿力来评估受损纤维的接触角（reta）值。损伤纤维的平均Rheta值随损伤程度的增加而降低。我们用电容技术研究了水沿沿着不同损伤的人发纤维的传输行为，该技术已由我们报道（2）。结果表明，角蛋白纤维损伤的类型和程度强烈影响水沿纤维束的沿着传输速率。
