For example, some non-woven fabrics used as interior materials have a decorative property enhanced by printing a floral pattern or a geometric pattern. However, it has been pointed out that this non-woven fabric is flat, has no depth, and is cheesy because it is only printed on the surface of the non-woven fabric.

However, the unevenness was shallow and it was not enough to change the impression that it was flat. In addition, since this nonwoven fabric forms irregularities by pressing, the softness and warmth inherent in the nonwoven fabric are removed, and the nonwoven fabric feels hard and cold. Further, when this non-woven fabric was laminated to a board or a wall, it had no cushioning property and was hard to compress.

が含まれていてもよい。The non-woven fabric contains latently crimpable fibers. The latently crimpable fiber means a fiber having a structure which is highly crimped by heating, and is composed of, for example, a composite fiber composed of two or more kinds of resins having different melting points,
A fiber that has a structure that is highly likely to be crimped by heating such as side-by-side or eccentricity, or a fiber that is composed of a resin of the same component, and receives thermal history such as rubbing with one side only on one surface and the thermal behavior of the fiber There may be mentioned fibers which are processed so as to be different from other portions.
The amount of latently crimpable fibers contained in the non-woven fabric is arbitrary,
All of the constituent fibers of the non-woven fabric may be latently crimpable fibers. Further, the nonwoven fabric may contain a plurality of types of latently crimpable fibers.

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 non-woven fabric so as to penetrate the front surface side or the non-woven fabric surface to the back surface.

れているのである。In the non-woven fabric of the present invention, the latent crimpable fibers of the non-woven fabric are crimp-developed in the state where the resin is applied. Is fixed to some extent and its movement is restrained, and the latently crimpable fiber is not crimp-expressed or is crimp-expressed to a low degree. On the other hand, in the non-resin-applied part to which the resin is not attached, the latent crimpable fiber is in a highly crimped state because it is not constrained by the resin. The intertwined constituent fibers in the non-woven fabric contract due to the pulling force of the latent crimpable fibers due to the pulling force, but as described above, the latent crimp in the resin-applied part and the non-resin-applied part The degree of crimp development of the natural fibers is different. For this reason, the shrinkage in the non-resin-applied portion where the crimp expression is highly caused is large, and the shrinkage in the resin-applied portion where the crimp expression is low or the crimp expression is low becomes small. A contraction difference occurs between the non-woven fabric and the portion, and the unevenness is formed in the nonwoven fabric due to the strain due to the contraction difference.

合してもよい。The fibers constituting the fibrous web may be any of polyethylene, polypropylene and the like, and the latently crimpable fiber having a structure which is highly crimped by the above-mentioned heating is mixed therein. The blending amount of the latent crimpable fiber is not particularly limited, but as the blending amount is increased, the unevenness of the uneven shape of the nonwoven fabric generated when the latent crimpable fiber is crimp-expressed is increased. Getting bigger,
If the compounding amount is small, the unevenness of the uneven shape of the nonwoven fabric becomes small. The latent crimpable fiber has a different degree of crimping depending on its type. Therefore, the type and the amount of the latently crimpable fiber to be mixed in the fibrous web may be appropriately determined in consideration of the pattern and uneven shape of the nonwoven fabric to be manufactured. According to the experiments of the present inventor, polyethylene terephthalate (melting point 265 ° C.) / Copolymerized polyester (melting point 235 ° C.),
When a latent crimpable fiber such as polypropylene / modified polypropylene is used, the content of the latent crimpable fiber is set to 30% or more, preferably 50% or more, so that the nonwoven fabric produced when the latent crimpable fiber is crimp-developed. It has been confirmed that the unevenness becomes large and the nonwoven fabric can be created as a three-dimensional object having a full and warm texture. In addition, all the constituent fibers of the fibrous web may be latently crimpable fibers, and the number of latently crimpable fibers to be blended into the fibrous web is not limited to one, but a plurality of latently crimpable fibers may be blended. May be.

維の捲縮が発現しない温度とすることが望ましい。The constituent fibers of this fibrous web are entangled by hydroentanglement or needle punching. The nonwoven fabric thus obtained has a degree of freedom such that the constituent fibers can cope with the change when the crimp of the latently crimpable fiber appears. The drying temperature during hydroentangling is preferably a temperature at which the crimp of the latently crimpable fiber does not develop.

る。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 preferably 10 to 50%, and if the area occupied by the resin-applied portion is smaller than this, the entire nonwoven fabric is latently latent. Since the crimpable fibers are crimped, unevenness is less likely to occur. On the other hand, when the crimped fiber is larger than this, a wide area of the non-woven fabric surface is covered with the resin, and the soft feel is apt to be lost. In particular, the 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, when a large number of small specific shapes such as circles, triangles, squares, polygons, and stars are printed on the surface of the non-woven fabric so as to be regularly distributed, the latent crimpable fiber When the crimp is developed, many irregularities having regularity are formed on the nonwoven fabric, while when a relatively large pattern such as a flower or an animal is printed, irregularities are formed along the contour of the pattern. Area ratio and placement (pattern) of the resin application part
Is appropriately selected according to the intended use or purpose, but in terms of producing unevenness and depth, it is more effective to print a large number of small specific shapes in a regular distribution.

である。Next, the nonwoven fabric partially provided with the resin is heated to cause the latent crimpable fiber to be crimped. The heating temperature of the nonwoven fabric may be determined according to the temperature at which the latently crimpable fibers to be used develop crimps. By heating the non-woven fabric, the latent crimpable fibers in the non-woven fabric are crimped, and the entwined constituent fibers are contracted by the force of attracting each other. At this time, in the resin-applied portion to which the resin is attached, the constituent fibers are fixed to some extent by the resin and the movement thereof is restrained, so that the latent crimpable fibers do not develop crimps or the crimps are made to a low degree. It becomes a state of being expressed. Since the non-resin-applied portion to which the resin is not attached is not bound by the resin, the latently crimpable fiber is highly crimped. As a result, the shrinkage in the highly resin-developed crimp-developed portion is large, and the shrinkage in the crimp-developed resin-provided portion is low, or the shrinkage is small.
A difference in shrinkage occurs between the resin-applied portion and the non-resin-applied portion, and unevenness is formed in the nonwoven fabric due to the strain due to the difference in the contraction.

かからないようにするとよい。The heating for crimp-developing the latently crimpable fiber may be performed after the step of applying the resin, or may be performed at the same time when the applied resin is dried. In this case, it is not necessary to separately provide a heating step for crimp-developing the latently crimpable fiber after applying the resin, and the manufacturing process of the nonwoven fabric can be simplified. Further, when the latent crimpable fiber is crimp-developed, it is preferable that the nonwoven fabric be subjected to as little tension as possible so as not to hinder the crimping of the fiber.
