Title: Sanitary material
Inventor: MIKAMI IKUKO
IPC: D04H1/407
Filed: 2001-06-29
Abstract: PROBLEM TO BE SOLVED: To provide an extremely thin sanitary material having sufficient moisture absorbability. SOLUTION: The sanitary material has a body fluid absorbing layer and a water impermeable layer formed on one surface of the body fluid absorbing layer and the water impermeable layer has tackiness and is not provided with the so-called back sheet. Therefore, this sanitary material fundamentally comprises a two-layered structure composed of the body fluid absorbing layer and the water impermeable layer and has no back sheet. Since the sanitary material can be made thin and is not bonded under heating and pressure, it is homogenous and soft as a whole and has an extremely good use feeling. Moreover, the sanitary material has no independent waterproof sheet but generates no leaching of body fluids in the same way as a conventional sanitary material.  Since this sanitary material can be manufactured without using a process for bonding the waterproof sheet under heating and pressure, a manufacturing process can be simplified. Further, the sanitary material using a water collapsible nonwoven fabric and tackifier dissolved in water can be thrown in a flash toilet to be disposed.
