In view of this, if the present invention is applied to a fabric having a shielding factor of 80 to 90% which is in the group of good shielding factor (rank B) or a fabric having a shielding factor of 50 to 80% which is in a general level (rank C), the shielding factor-improving effect may be further enhanced.
  • FIG. 3 shows an apparatus for measuring fiber fabric temperatures by irradiating an underwear fiber fabric with infrared rays allowed to pass through it.
  • three heat insulation boards 11 , 11 and 11 are disposed at a prescribed interval, and horizontally-elongated heat insulation boards 12 , 12 and 12 are provided on the upper end of the boards 11 .
  • a temperature sensor 14 is placed at a space 13 which is surrounded by the heat insulation boards 11 and 12 .
  • a finished fabric 15 and an unfinished fabric 16 are placed, which fabrics are covered with a commercially available broadcloth shirt 17 , and subjected to infrared-ray irradiation for 20 minutes with an infrared lamp 18 located above the shirt, so that the temperatures of the fiber fabrics through which infrared rays have passed are measured by the temperature sensors 14 positioned about 5-mm directly below the finished fiber fabric 15 or the unfinished fiber fabric 16 .
  • This aims at measuring the difference in temperature in a condition close to a state where the fiber fabric is used as underwear.
  • Table 3 shows the results of the test. In the test, the outside air temperature (room temperature) is 27.4° C.
  • Table 4 shows the results of evaluations of antibacterial activity and deodorizing performance in Examples 1 to 6.
  • the antibacterial test was carried out by Daiwa Chemical Industries Co., Ltd., and the deodorization test was carried out by Boken Quality Evaluation Institute.
  • the antibacterial evaluation was performed according to Testing for antibacterial activity, Bacterial culture absorption method (based on JIS L 1902). In this table, the criteria are as follows:
  • the bacteriostatic activity value can be calculated by the following formula:
  • Mb is the average of common logarithm of viable cell count obtained after incubation for 18 hours on the unfinished fabric
  • Ma is the average of common logarithm of viable cell count obtained immediately after inoculation of testing bacteria on the unfinished fabric
  • Mc is the average of common logarithm of viable cell count obtained after incubation for 18 hours on the antibacterial finished fabric.
  • Mo is the average of common logarithm of viable cell count obtained immediately after inoculation of testing bacteria on the antibacterial finished fabric.
  • the deodorizing efficacy evaluation was performed according to a deodorizing performance test, JAFET standard detergent method, by instrumental analysis and assessment.
  • the criteria are as follows:
  • the deodorization rate (decrease rate) can be calculated by the following formulae.
  • Ammonia/Acetic acid Decrease rate (%) ⁇ ( A ⁇ B )/ A ⁇ 100
  • Isovaleric acid Decrease rate (%) ⁇ ( C ⁇ D )/ C ⁇ 100
  • the cool-feeling fiber fabric according to the present invention is advantageously applicable not only to clothing such as shirts, blouses and dresses, but also to apparel accessories such as hats, gloves and stockings, interior goods such as curtains, lace and blinds, and industrial materials such as sailcloth, cheesecloth and industrial sheets.
