This is because the stretch fabric of this embodiment increases the crimp of the inelastic yarn used for either the warp or the weft by heat setting, but utilizes the contraction force of the elastic yarn used for the other at the heat setting temperature. This is because the crimp of the inelastic yarn can be increased.
  • the shrinkage stress is less than 0.05 cN / dtex, it is necessary to pull the fabric in the elastic yarn direction in order to increase the crimp of the inelastic yarn, and it is possible to obtain a similar crimp height. There are concerns from the perspective. Further, if the shrinkage stress is 2.00 cN / dtex or more, the shrinkage force is large and there is a possibility that a large load is applied to the heat set machine.
  • the residual strain in the inelastic yarn direction after stretching and deformation after repeating 300,000 times of weighting / deweighting up to 340 N / 5 cm for constant speed elongation is 3% or less.
  • the residual strain is more preferably 1% or less.
  • a polyester elastomer yarn is used as the elastic yarn used for the warp or the weft, so that the stretch rate in the other inelastic yarn direction becomes a material.
  • a warp or weft using an elastic yarn may be woven with a polyester-based elastomer yarn as an elastic yarn and another yarn.
  • other yarns include fiber yarns made of polyester, polyamide, polyphenylene sulfide, and the like.
  • polyphenylene sulfide yarns are easy to use when partially using heat resistance from the viewpoint of heat resistance.
  • a polyester elastomer yarn and another woven yarn may be partially used as a method of woven with elastic yarn in warp or weft.
  • the ratio of the elastic yarn in the warp or weft using the elastic yarn is 50% by mass or more.
  • the number of the elastic yarn and the inelastic yarn is continuous.
  • the portion where the elastomer fibers are arranged exhibits high extensibility. For this reason, by weaving many pieces continuously, it becomes a woven fabric having a partially high stretch.
  • the woven fabric can be designed with the required length of the stretch according to the application, and the woven fabric having both the stretch performance and other performances becomes possible.
  • a fabric having high heat resistance at both ends of the fabric and high extensibility can be obtained.
  • the stretch fabric of the present embodiment is a vehicle seat sheet member, a member such as a shoe skin material, a bag, a sports ball member such as soccer or volleyball, an adhesive tape, a non-woven fabric base fabric, an interior member, a vehicle / house inner layer. Used for applications such as construction materials and civil engineering materials.
  • the structure of the stretch woven fabric in this embodiment may be appropriately selected according to the use, such as a plain structure, a twill structure, a satin structure, or a double structure combining these structures. Since the flat structure has many intersection points, the stretchability in the inelastic yarn direction tends to be high, and handling properties such as anti-slipping are also good. Further, the weaving method and the loom to be used are not particularly limited, and may be appropriately selected.
  • Crimp rate A non-elastic yarn or a sample (woven fabric) cut in parallel with the elastic yarn is taken in a non-tensioned state and bonded to the sample table, and an enlarged photograph is taken. From the crimp interval and height of the non-elastic yarn or elastic yarn The distance between crimps (mm) was determined. The distance (mm) between the centers of the elastic yarns or inelastic yarns adjacent to each other was measured at five locations, and the crimp rate (C) was determined by the following equation, and the average was calculated (see FIG. 1).
  • Crimp rate (C) (L / D-1) x 100 (%) [In the formula, L is a distance (mm) between crimps of inelastic yarns or elastic yarns, and D is a distance (mm) between centers of adjacent elastic yarns or inelastic yarns. ]
  • Elongation rate when woven fabric is 340N / 5cm
  • the center of the test piece is 300mm in diameter
  • the center of the circle is 200mm in the inelastic thread direction, 50mm
  • the elongation at the time of reaching 340 N at a pulling speed of 200 mm / min was measured for five samples, and the average was calculated.
  • Residual Strain “Servo Pulser” (registered trademark) (manufactured by Shimadzu Corporation) was used to calculate the residual strain R after repeatedly deforming the woven fabric in the inelastic yarn direction under the following conditions.
  • Elongation rate when woven fabric 735N / 5cm is applied In accordance with JIS-L-1096, using a constant speed extension type tester, the center of the circle of the test piece with a diameter of 300mm is the center, and the holding interval of 200mm in the inelastic yarn direction, With a grip width of 50 mm, the elongation at 735 N at a tensile speed of 200 mm / min was measured for five samples, and the average was calculated.
  • Dry heat shrinkage stress Take 10 cm filament yarn of sample and tie both ends into a loop. This is subjected to a dry heat treatment with a heat shrinkage stress measuring instrument manufactured by Kanebo Corporation under a load of 0.03 cN / dtex while gradually raising the temperature from room temperature to 230 ° C. The maximum shrinkage stress (cN) at this time is read and divided by the total fineness (dtex) of the yarn to obtain the shrinkage stress (cN / dtex) per single fiber fineness.
