Description of the Related Art As a nonwoven fabric for wet tissue used for wiping dirt containing water, such as excrement of infants and spills on a table, and hand wiping, for example, cotton or rayon is used. Non-woven fabrics made of cellulosic fibers, etc., and non-woven fabrics obtained by blending a predetermined amount of PET / PP core-sheath type crimpable fibers with the cellulose fibers are known.

ける厚みと肌触りとは相反する性質のものであった。[0003] Among these nonwoven fabrics, the nonwoven fabric made of cellulosic fibers has good touch, but lacks the thickness in a wet state, and sometimes has insufficient mechanical strength at the time of wiping. On the other hand, in the case of a nonwoven fabric in which a PET / PP core / sheath type crimpable fiber is blended with a cellulosic fiber, the thickness in a wet state increases due to the action of the crimpable fiber, and the mechanical strength increases. The feel is reduced due to the tingling and the like caused by the crimped fibers. As described above, the thickness and the feel of the nonwoven fabric for wet tissue are of opposite properties.

m, fineness: 1.5 denier) was opened using a carding machine to form a fiber web. Next, the fibers in the fiber web are mechanically entangled with each other using a high-speed water flow (pressure 35 kg / cm 2 ), and further dried with hot air (100 ° C.).
By doing so, a nonwoven fabric having a basis weight of 40 g / m 2 was produced. The fiber density and thickness of the obtained nonwoven fabric under a load of 0.55 g / cm 2 were measured. Table 1 shows the results.
Shown in Next, the obtained nonwoven fabric was impregnated with 240% of water to obtain a wet tissue. With respect to this wet tissue, the touch was evaluated by the following method, and the thickness under a load of 0.55 g / cm 2 was measured. Table 1 shows the results.
