た。Table 2 Example 2 75D-36F having fine granular irregularities on the surface of each filament fiber of polyester multifilament (
Raw yarn with a single yarn denier of approximately 2.0 denier was woven vertically and horizontally into a Ponzi structure, treated as glue and refined, and then processed to reduce its weight by 10% with caustic soda (NaOH).The resulting fabric was neutralized, After washing and drying, heat at 180'C for 40 minutes.
When heat set was applied for a second, a fabric was obtained which had fine granular irregularities and fine wrinkle-like surface irregularities on each surface of each filament constituting the cloth. This fabric was immersed in a nickel electrolyte as a base fabric, and the amount of Ni plating (y/-rIt) was
After applying plating of 15.5, an acrylic resin coating process was performed on the plating film to produce an electromagnetic wave shielding fabric.
