- the nonwoven fabric of the present invention uses a fiber having a heat-fusible component on the surface as a composite short fiber constituting the nonwoven fabric, and heats a web made of this fiber with a deep groove embossing roll in which the depth of the convex portion of the embossing roll is large.
- embossing After embossing, at least one end of the composite staple fiber in a portion serving as an island region protruding to the surface side enters a portion serving as a sea region, and is in a state of being heat-fixed in the sea region during the hot embossing. It is a thing.
- this nonwoven fabric is a nonwoven fabric obtained by embossing a bulky web with a deep groove, it is lightweight, has a soft feel, is thin and flexible, and can be manufactured at low cost. As a material used in disposable products such as diapers Very good.
- FIG. 1 is a perspective view showing an example of the nonwoven fabric 1 of the present invention.
- FIG. 2 is a cross-sectional view taken along line XX of FIG.
- the nonwoven fabric 1 of the present invention is obtained by using a bulky web made of a heat-fusible composite fiber of a core-sheath type or a side-by-side type as described above, and embossing the web.
- a region consisting of a non-embossed surface is regularly or irregularly dispersed as a large number of island regions I having a convex shape protruding to the surface side.
- the crimping region surrounding each of the island regions I is configured as a sea region S.
- Such a structure has an embossed opening with a deep groove on the roller surface. And the bulky web is embossed using a pair of rollers.
- the maximum diameter D (Fig. 2) of the non-embossed surface dispersed and present as the island region I of the nonwoven fabric 1 is shorter than the apparent length of the short fiber in the web, that is, the island region I is formed. It can be obtained by controlling the apparent length of the short fibers in the web and the maximum diameter of the bottom of the island region so that at least one end of the composite short fibers is thermally fixed in the sea region S. Things.
- the fibers in the island region serving as the loop-side engaging element are heat-sealed to each other by the fibers constituting the island region to fix the loop shape to some extent, and to fix the loop. Even if the fiber to be formed is subjected to a tensile force, it must be strong and heat-fusible so that the fiber is fixed by thermal bonding in the sea area and does not come off. Therefore, in response to such a requirement, a core-sheath type or side-by-side type composite fiber having one as a strength retaining component and the other as a heat-sealing component is used.
- Examples of the combination (core Z sheath) of both polymer components of such a heat-fusible conjugate fiber include a combination of polypropylene Z polyethylene, a combination of polypropylene modified polypropylene, and a polyethylene terephthalate nopolyamide (nylon). Combination, polyethylene terephthalate / polyethylene combination, polyethylene terephthalate / polypropylene combination, polyamide (NIPPON) / polyethylene combination, polyamide (na (Silon) / polypropylene combinations.

- the melting point of the sheath layer polymer is 120 ° C or lower, it is not preferable in terms of the hardening of the hand after fusion and the heat resistance during use (processing).
- the combination of these two polymer components is preferably a combination in which the core layer polymer and the sheath layer polymer have a difference in melting point of 30 ° C. or more. This is to prevent loss of the properties of the core component that retains the mechanical properties of the fiber during hot embossing. Further, a combination having affinity for both polymers is preferred.
- the heat-fusible conjugate fiber In the present nonwoven fabric, it is necessary to use 100% (%) of the heat-fusible conjugate fiber because of the mechanical strength of the loop-side engaging element, that is, when a peeling force or a tensile force is applied. It is more preferable in terms of preventing the fiber from coming off and preventing the loop form from breaking, but this point can be covered by other configurations of the fiber, and it is not always necessary to use 100%. It is sufficient if it is at least 80% of the total fiber, and the cost can be reduced by reducing the amount of the heat-fusible conjugate fiber used.

- a protrusion having a circular, rectangular, rhombic, or any other bottom shape has a convex shape rising from the sea region S. Embossed surface).
- the short fibers are thermally fused together at their intersections to form a loop for the hook.
- the sea area s surrounding the island area I has become the crimped surface (enbossed surface) by indigo embossing of the web, and this area has fewer short fibers forming the island area and forming loops. Both ends reach that part, where they are subjected to heat embossing and are fixed by thermal fusion so that they do not come off, and they are where the nonwoven fabric is mainly maintained in its shape.
- Each island region I may be arranged regularly or irregularly.Therefore, the sea region S surrounding each island region I also has a continuous force sea region S according to its arrangement form. In other words, it is not essential that it surrounds each island region I, as long as at least one end of the short fiber forming the loop of the island region can be heat-fixed in the sea region. Good.

- the number of crimps and the rate of crimp are less than 10 inches and less than 5%, the required bulkiness cannot be obtained.
- the number of crimps and the rate of crimps exceed 20 inches and 20%, It is preferable that the hook-shaped engaging element and the loop-shaped engaging element are insufficiently engaged with each other, and the appearance change (fluffing) due to repeated peeling becomes large.
- each of the convex island regions I is required to have a height that protrudes above the surface of the nonwoven fabric so that the hook-side engaging elements can be easily hooked. That is, each island region I must have a height H (Fig. 2) from the sea area s plane surrounding each island area I to the top of the island area I (Fig. 2) of 0.3 mm or more. Is preferred. If it is less than 0.3 mm, it is not preferable because the hook-shaped engaging element is less likely to be caught.
- the height H is preferably 3 mm or less in view of manufacturing restrictions, the height of the hook side engaging element (usually less than 2 mm), and delamination.
- the island region I of the convex shape has just become a non-pressed surface (non-embossed surface) due to the embossing of the nonwoven fabric, and has a convex shape rising from the sea region S.
- the shape viewed from above the surface of the nonwoven fabric is not limited to a circular shape, but can be formed in any shape. However, it is preferable that the shape has an area with an average diameter D of about 2 to 8 mm in terms of a circular shape. In the island region I having an average diameter D of less than 2 mm in terms of the circular shape, the engaging area on the upper surface cannot be effectively secured, which is not preferable.
- both ends of the short fibers constituting the upper surface do not reach the sea area, and the number of fibers that are heat-fixed only in one end in the sea area increases.
- the hook-side engaging element is hooked on the upper surface and a pulling force is applied, the short fibers are easily pulled out and a loop is broken, which is not preferable. It is not preferable because it decreases due to deformation (displacement) of the loop.
- the point is that the maximum diameter of the bottom surface of the projecting portion dispersed and present as an island region is larger than the apparent length of the short fibers constituting the web. It is necessary to control the length of the constituent short fibers and the size of the island region so that at least one end, preferably both ends, of the conjugate short fibers constituting the island region are heat-fixed in the sea region so as to be short. Is essential.
