It is known that a fabric is subjected to a gluing process in order to make dry stains such as soot less likely to adhere and to make attached dry stains easier to remove by washing, but this method is effective for cotton fabrics. However, there is almost no effect on lipophilic and easily darkened synthetic fiber fabrics, and gluing is required every time washing is performed. It is also known that a cloth is treated with a mixed colloidal dispersion of silica and alumina, and the fine gaps on the fiber surface are filled with colorless colloidal fine particles for smoothing.
This is also effective for cotton fabrics, but not for synthetic fiber fabrics, and lacks durability.

Since this antifouling coating is hard, it prevents the above-mentioned dry dirt such as earth and sand, floating dust, and soot from penetrating into the fiber, making it difficult to adhere, and the coating surface is hydrophilic and has a drip property. And the surface is easy for water to flow, so that the attached dirt can be easily removed by running it with rainwater or washing with water.

In particular, sputter deposition and ion plating can withstand at least five home washings.

Since it is an aggregate, the texture of the fiber sheet is maintained without touching the film, and the needle-shaped body does not peel off even when the fibers constituting the fiber sheet are bent, so that the durability is further improved.

After the antifouling coating 12 on the front surface is formed, the fiber sheet 11 is turned over, and then the antifouling coating 12 made of a mixture of SiO 2 and Sn O 2 is formed on the back surface in the same manner as described above. The target may be made of silicon or tin, or may be made of SiO 2 or Sn 2 O and may be sputtered in an inert gas atmosphere. Further, it is preferable that the fiber sheet 11 be cooled from the back surface with a water-cooled cylinder or the like to maintain the temperature at 100 ° C. or less.

The untreated lace curtain (comparative example) showed almost no difference in appearance and feel,
When the apparatus was hung outdoors for a month and visually inspected for dirt in the open air, the examples were clearly less dirt than the comparative examples. Then, when the laundry was washed with a home washing machine, dirt was removed faster in the example than in the comparative example, and the degree of staining after repeating the washing five times was almost the same as in the beginning. Immediately after the trial production of the above example, a commercially available packing gum tape was stuck on the antifouling film, and a peeling test was performed. As a result, no peeling of the antifouling film was observed.
