2. Description of the Related Art
For example, there is a nonwoven fabric used for an interior material in which a decorative pattern is enhanced by printing a floral pattern, a geometric pattern, or the like. However, it has been pointed out that this nonwoven fabric is flat, lacks depth, and feels cheap because it is only printed on the surface of the nonwoven fabric.

[0003] Therefore, there has been proposed a method in which the printed non-woven fabric is embossed to form irregularities on the non-woven fabric, thereby eliminating the point of being flat and having no depth.

However, in this nonwoven fabric, the printed nonwoven fabric is crushed by an embossing roller into irregularities to form irregularities, so that the pattern is sharper than that of an unprocessed one. However, the unevenness was shallow, not enough to change the impression of flatness. In addition, since the nonwoven fabric forms irregularities by pressurizing, the softness and warmth inherent in the nonwoven fabric are removed, and the nonwoven fabric is hard and cold. Further, when this nonwoven fabric was bonded to a board or a wall, the nonwoven fabric had no cushioning property and had a compression hardness.

Fibers that have a structure that is easily crimped by heating such as side-by-side or eccentricity, or fibers that are made of the same component resin. And fibers processed to be different from other portions.
Incidentally, the amount of latently crimpable fibers contained in the nonwoven fabric is arbitrary,
All of the constituent fibers of the nonwoven fabric may be latently crimpable fibers. Further, the nonwoven fabric may contain a plurality of types of latently crimpable fibers.

The resin is applied to the surface of the nonwoven fabric by printing a floral pattern or a geometric pattern on the surface of the nonwoven fabric.
Alternatively, it is provided so as to penetrate from the front surface to the back surface of the nonwoven fabric. By applying the resin, the resin is attached to the constituent fibers of the nonwoven fabric such that the resin penetrates from the front surface side or from the front surface to the back surface of the nonwoven fabric.

In the nonwoven fabric of the present invention, since the latently crimpable fibers of the nonwoven fabric are crimped in a state where the resin is applied, the resin-applied portion to which the resin is attached has a resin Is fixed to some extent, the movement thereof is restricted, and the latently crimpable fiber is in a state where no crimp is developed or a state where crimp is developed to a low degree. On the other hand, in the non-resin-applied portion to which the resin is not attached, the latently crimpable fiber is in a state of highly crimping because it is not restrained by the resin. The intertwined constituent fibers in the nonwoven fabric are shrunk by the attraction of each other due to the crimping of the latently crimpable fibers. The degree of crimping of the conductive fiber is different. For this reason, the shrinkage in the non-resin-applied portion where crimps are highly developed is large, and the shrinkage in the resin-applied portion where no crimps is developed or the crimp is developed to a low degree is small, and the resin-applied portion and the non-resin-applied portion are reduced A difference in shrinkage is generated between the nonwoven fabric and the non-woven fabric.

The fibers constituting the fibrous web may be any fibers such as polyethylene and polypropylene, and are blended with the above-described latently crimpable fibers having a structure that is highly crimped by heating. The amount of the latently crimpable fiber is not particularly limited, but as the amount is increased, the unevenness of the nonwoven fabric generated when the latently crimpable fiber is crimped is increased and decreased. Get bigger,
If the compounding amount is small, the unevenness of the nonwoven fabric becomes small. In addition, the degree of crimping of latently crimpable fibers differs depending on the type. For this reason, the type and the amount of the latently crimpable fiber to be blended in the fiber web may be appropriately determined in consideration of the pattern and uneven shape of the nonwoven fabric to be produced. According to experiments performed by the present inventors, polyethylene terephthalate (melting point: 265 ° C.) / Copolyester (melting point: 235 ° C.)
When a latently crimpable fiber such as polypropylene / modified polypropylene is used, by setting the blending amount to 30% or more, preferably 50% or more, the non-woven fabric generated when the latently crimpable fiber is crimped is developed. It has been confirmed that the unevenness of the unevenness becomes large, and that the nonwoven fabric can be created as a three-dimensional object having a plump and warm texture. In the fibrous web, all of the constituent fibers may be latently crimpable fibers, and the number of latently crimpable fibers to be blended in the fiber web is not limited to one. You may.

The constituent fibers of the fiber web are entangled by hydroentanglement or needle punching. The resulting non-woven fabric has a degree of freedom such that the constituent fibers can cope with the change when the crimping of the latently crimpable fiber occurs. The drying temperature at the time of the hydroentanglement is desirably a temperature at which crimping of the latently crimpable fiber does not occur.

The resin is partially applied to the entangled nonwoven fabric.

It may be provided so as to penetrate.

It is desirable that the ratio of the total area of the resin-applied portion formed by printing or the like to the surface of the nonwoven fabric is 10 to 50%. Since crimping of the crimpable fiber occurs, unevenness is less likely to occur. On the other hand, if it is larger than this, a wide area of the surface of the nonwoven fabric is covered with the resin, so that a soft feel is easily lost. In particular, a preferable ratio of the total area of the resin application portion is 15 to 40%. In the case of forming the resin-applied portion, for example, printing on a nonwoven fabric surface such that a large number of small specific shapes such as circles, triangles, squares, polygons, and stars are regularly distributed, the latently crimpable fiber When crimping is developed, a large number of irregularities having regularity are formed on the nonwoven fabric. On the other hand, when a relatively large picture such as a flower or an animal is printed, irregularities are formed along the contour of the picture. Area ratio and arrangement (pattern) of the resin application section
Is appropriately selected depending on the application and purpose, but in terms of providing unevenness and depth, it is more advantageous to print such that a large number of small specific shapes are regularly distributed.

Next, the non-woven fabric partially provided with the resin is heated so that the latently crimpable fibers are crimped. The heating temperature of the nonwoven fabric may be determined in accordance with the temperature at which the latently crimpable fibers used exhibit crimping. By heating the non-woven fabric, the latently crimpable fibers in the non-woven fabric are crimped, and the entangled constituent fibers are attracted to each other and contract. At this time, in the resin-applied portion to which the resin is attached, since the constituent fibers are fixed to some extent by the resin and the movement thereof is restricted, the latently crimpable fiber does not develop crimp or is crimped to a low degree. It will be in a state of expression. Since the non-resin-applied portion to which the resin is not attached is not restricted by the resin, the latently crimpable fiber is in a state in which the crimping is highly expressed. As a result, the shrinkage in the non-resin-applied portion where crimps are highly expressed is increased, and the shrinkage in the resin-applied portion where crimps are not expressed or expressed at a low degree is reduced,
A difference in shrinkage occurs between the resin-applied portion and the non-resin-applied portion, and irregularities are formed on the nonwoven fabric due to the strain caused by the difference in shrinkage.

The heating for causing the latently crimpable fibers to be crimped may be provided after the step of applying the resin, or may be performed simultaneously with the drying of the applied resin. In this case, there is no need to separately provide a heating step for causing the latently crimpable fibers to be crimped after the application of the resin, and the manufacturing process of the nonwoven fabric can be simplified. Further, when the latently crimpable fiber is subjected to crimping, it is preferable that the nonwoven fabric is not subjected to tension as much as possible so as not to hinder the crimping of the fiber.
