Abstract
The present invention provides a personal hygiene item. In simple terms, one of the main features of the present invention is to provide a low-cost personal hygiene item capable of providing a multi-component detection function. The personal hygiene item of the present invention mainly comprises a first material layer and a second material layer. The first material layer is made of hydrophobic material, and the second material layer is disposed thereon. Also, the second material layer comprises a discolored portion. In actual practice, a fluid under test contacts with the corresponding discolored portions via the hydrophobic layer of second material layer for a color changing reaction. Meanwhile, since the hydrophilic performance of the discolored portion is better than the hydrophilic performance of the hydrophilic layer, the back permeation of the fluid under test can herein be prevented.
