Water Detection Method in the Diffusion Layer of Diaper

Diapers requires good water absorption characteristics, so that users can maintain optimal degree of freshness. To find diapers absorption and diffusion of moisture condition, there must be appropriate detection method to detect moisture. The common methods of measuring textiles moisture diffusion range are Impedance measurement method, capacitive measurement method, chemical substances measurement method, image measurement method. These methods are limited to the amount of surface measurement, and it's hard to be informed of the inner diffusion situation; radiography measurement method can measure the internal diffusion conditions, but requires expensive equipment and space environment for its main drawback. This paper presents the method called Sensing Probe Puncture. Through the Diaper Method (SPPTDM) and device that can detect moisture in the diaper diffusion layer. Experimental design and data processing and analysis, the results to prove that the diffusion layer of moisture diffusion rate is greater than the diffusion rate of the surface to prove diapers absorb moisture diffusion is the main diffusion layer. 
