It is more preferable that the area of the valley portion satisfying the above and the depth of 3 μm or more is less than 3% of the total area.

Furthermore, it is highly preferred that these conditions have a center line average roughness of less than 0.5 μm, and a maximum height of less than 5 μm, and substantially no Beck. It is very preferable that the smoothness is 100 seconds or more, and in the two-dimensional photographed image from above the fabric, the area of the valley portion that satisfies the width of 5 μm or more, the length of 50 μm or more, and the depth of 3 μm or more, 1% of total area
It is highly preferred that it is less than.

For the second object of the present invention, these cloths have a very smooth surface, so that high glossiness is exhibited. If the fibers on the surface of the fabric are not extremely dense, the above conditions cannot be substantially satisfied. On the contrary, if the above conditions can be satisfied, the mites-preventing property, the fall-off preventing property or the retaining property of feathers can be achieved. Is exhibited, and air permeability is also suppressed, so that cold protection is also exhibited. Furthermore, since the fibers are dense, they are resistant to loosening, dirt is less likely to adhere, and they have good waterproofness.

The surface smoothness is imparted to the surface smooth cloth of the present invention in the state where the image and the like are dyed in the background by using a thermal transfer printer or a sublimation type thermal transfer printer, and further characters, images or identification marks It is also preferable to record etc.

When it is used for clothing or the like for the second object of the present invention, it is originally excellent in waterproofness, but if water-repellent treatment is further applied, desirable results may be obtained, so it should be used appropriately. Is. At that time, it is preferable that the water repellency is 90 points or more. According to the knowledge of the present inventors, since the water repellency of the cloth using the ultrafine fibers is 100, the cloth using the ultrafine fibers is obtained. Combined with the thinness, it is extremely preferably used for windbreakers, ground jackets and the like.

For example, when used for a sail such as a spinnaker, water repellent treatment may be carried out after processing, but it is also preferable to carry out antifouling processing. However, since it is generally difficult to perform these processes after pressing, it is preferable to perform these processes first and then press process.
In that case, an extremely excellent feature that the treating agent permeates every corner of the fine structure is exhibited. This processing method is
It is not limited to the case of spinnaker.
