PROBLEM TO BE SOLVED: To provide a confirmation method of split degree of a splittable conjugate fiber enabling confirmation of split degree of the splittable conjugate fiber of a nonwoven fabric and quality control of the nonwoven fabric in a manufacture site.SOLUTION: A confirmation method of split degree confirms split degree of a splittable conjugate fiber of a nonwoven fabric including a super-thin fiber, which is split from the splittable conjugate fiber. The method irradiates a surface of the nonwoven fabric with a laser beam and measures laser intensity which penetrated the nonwoven fabric. |
