  • the cut pile fabric was supplied to a dry heat setter, and thermally treated at a temperature of 180° C. for a time of 45 seconds to stabilize the non-crimped polyethylene terephthalate multifilament yarns in the cut piles, sufficiently form the crimps of the polyethylene terephthalate multi false-twisted crimped yarns resin-dyed with the pigment, and sufficiently thermally shrink the non-crimped cationic dye-dyeable polyethylene terephthalate yarns.
  • cut piles 2 having the largest cut pile height, cut piles 4 having the lowest cut pile height, and cut piles 3 having the middle cut pile height were formed from the non-crimped polyethylene terephthalate multifilament yarns, the non-crimped cationic dye-dyeable polyethylene terephthalate yarns, and the polyethylene terephthalate multi false-twisted crimped yarns resin-dyed with the pigment, respectively.
  • the obtained cut pile fabric was dyed with a cationic dye (blue) at 130° C. for 30 minutes by use of a jet dyeing machine manufactured by (Ltd.) Hisaka Seisakusho, dried, and then pre-set to obtain the pile fabric (cut pile density: 129,642 dtex/cm 2 ) having the cut piles (the height of the cut piles 2 mm) and having a knit density of 68 courses/2.54 cm and 30 wales/2.54 cm.
  • a cationic dye blue
  • the inclined portions formed were the inclined portions as typically shown in FIG. 2 , and the inclination angle A, depth difference H, and inclination length W of each of the inclined portions were 2 degree, 0.8 mm, and 10 mm, respectively.
  • the number of concaves per unit area was 100 concaves/cm 2 , and the rate of the concaves was 5%, and the surface of each of the inclined portions scarcely had fine concaves and fine convexes, and was smooth.
  • the highest portions, middle portions, and lowest portions of the cut pile portion along the slopes of the inclined portions were looked in a white color, a black color, and a black-blue mixed color, respectively. Therefore, the pile fabric was greatly excellent (grade 5) at the point of high grade sense.
  • Example 2 Similarly as in Example 2 except that the number of the rotary screens was changed to 2, the cut pile portion was partially removed by a chemical etching method to obtain the pile fabric in whose cut pile portion the slopes were formed.
  • the inclination angle A, depth difference H, and length W of each of the inclined portions were 2 degree, 0.8 mm, and 10 mm, respectively.
  • the number of concave portions per unit area was 120 concaves/cm 2 , and the rate of the concaves was 20%. Fine concaves and fine convexes were somewhat looked on the surfaces of the inclined portions, but the pile fabric was excellent (grade 4) at the point of high grade sense.
  • the pile fabric obtained in Example 2 was color-printed with a usual ink jet. Said fabric subjected to the color-printing had an appearance having good depth and compact inclination differences in response to a looking angle, and was excellent.
  • Example 2 Similarly as in Example 1 except that the discharging amount of each rotary screen was changed to 26.3 cm 3 /m 2 and the number of the rotary screens was changed to 1, the cut pile portion was partially removed by a chemical etching method to obtain the pile fabric in whose cut pile portion the slopes having many fine concaves and convexes were formed.
  • the inclination angle A, depth difference H, and length W of each of the inclined portions were 2 degree, 0.8 mm, and 10 mm, respectively.
  • the number of concave portions per unit area was 150 concaves/cm 2 , and the rate of the concaves was 25%. Fine concaves and convexes were looked on the surfaces of the inclined portions, but the pile fabric was somewhat good (grade 3) at the point of high grade sense.
  • the pile fabric of the present invention can suitably be used in fields such as vehicle interior materials, interior materials, and clothes, and has high practicality, because of having moderate inclined portions on the surface of the cut pile portion and thereby giving rich high grade sense.
