The nonwoven fabric is formed by jetting a fluid, which consists mainly of gaseous matter, to a fiber web 100 supported from beneath by a predefined breathable support member, from an upper surface side in order to move fibers in the fiber web 100. A number of groove portions 1 and a number of convex portions 2 are formed on a jetted area of the nonwoven fabric in the direction in which the area is extended, and the fiber density of the groove portions 1 is less than the fiber density of the convex portions 2.

SUMMARY OF THE INVENTION The nonwoven fabric disclosed in JP-A No. 3587831 has a second fiber layer containing fibers that are resistant to shrinking when heat is applied formed on one side or both sides of the first fiber layer, within which include the fibers that shrink when heat is applied, and the fiber layers are sealed and combined in a large number of heat sealed areas. The second fiber layers are protruded to form many convex portions by heat contraction of the first fiber layer in the heat sealed area.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a perspective view of a fiber web;
DETAILED DESCRIPTION OF THE INVENTION The best embodiments of the present invention will be explained referring to figures below.
1. First Embodiment The nonwoven fabric of the present invention according to the first embodiment will be explained while referring to FIGS. 2 to 5.
When the fibers 101 are oriented at angles in the range of +45� and −45� relative to the longitudinal direction (machine direction), the fibers 101 are said to be oriented in the longitudinal direction (machine direction), and the fibers oriented in the longitudinal direction are called �longitudinally oriented fibers�. When the fibers 101 are oriented at angles in the range of +45� and −45� relative to the width direction, the fibers 101 are said to be oriented in the width (lateral) direction, and the fibers oriented in the width direction are called laterally oriented fibers.
2. Other Embodiments The nonwoven fabric of the present invention according to other embodiments will be explained below. The features similar to the nonwoven fabric according to the first embodiment are not particularly explained in the embodiments below, and numbers given to figures are the same as described in the first embodiment if this is the case.
2.1. Second Embodiment The nonwoven fabric of the present invention according to the second embodiment will be explained referring to FIG. 10.
2.2. Third Embodiment The nonwoven fabric of the present invention according to the third embodiment will be explained referring to FIGS. 11 and 12.
2.3. Fourth Embodiment The nonwoven fabric of the present invention according to the fourth embodiment will be explained referring to FIG. 13.
2.4. Fifth Embodiment The nonwoven fabric of the present invention according to the fifth embodiment will be explained by referring to FIG. 14.
2.5. Sixth Embodiment The nonwoven fabric of the present invention according to the sixth embodiment will be explained referring to FIGS. 15 and 16.
2.6. Seventh Embodiment The nonwoven fabric of the present invention according to the seventh embodiment will be explained by referring to FIGS. 17 and 18.
3. EXAMPLES 3.1. Example 1 Fiber Structure
3.2. Example 2 Fiber Structure
3.3. Example 3 Fiber Structure
3.4. Example 4 Fiber Structure
4. Examples of Application For example, the nonwoven fabric of the present invention can be used as a surface sheet of absorbent products such as sanitary napkins, pantiliners and diapers. In this case, the convex portions may be the side which comes in contact with the skin or the reverse side, but making the convex portions the side which comes in contact with the skin, the contact area with the skin is reduced and it may be unlikely for the users to feel wet from the body fluid. In addition, the nonwoven fabric may be used as intermediate sheets between surface sheets and absorbers of the absorbent products. The contact area with the surface sheets or absorbers is reduced, thereby making the liquid unlikely to reverse its course from the absorbers. Furthermore, the nonwoven fabric may be used as side sheets of absorbent products, outermost of diapers, etc. and zip fastener materials, taking advantages of reduction in contact area with the skin or their cushion-like feel. The nonwoven fabric may also be used for various purposes such as wipers for removing dusts or dirt attached to the floor or body, masks and nursing milk pads, etc.
