Definitions

  • the present invention relates to a nonwoven fabric.
  • halogen-based chemicals and phosphorus-based chemicals are generally used, but replacement of halogen-based chemicals with phosphorus-based chemicals have recently proceeded because of the environmental regulations. However, there are some phosphorus-based chemicals which do not reach the flame retardant effect of conventional halogen-based chemicals.
  • Patent Document 1 paper formed of a composite of a flame resistant yarn and a polyphenylene sulfide fiber (Patent Document 1) and a felt formed of a composite of a flame resistant yarn and a polyphenylene sulfide fiber (Patent Document 2) are known.
  • the weight of a 30 cm square sample was measured and expressed in weight per 1 m 2 (g/m 2 ).
  • the thickness was measured conforming to JIS L 1913 (2010).
  • Soft urethane foam commercially available from Fuji Gomu co., Ltd. is cut into a length of 20 cm, a width of 20 cm, and a thickness of 20 cm to obtain urethane foam 1.
  • the nonwoven fabric 2 of the present invention is covered on the surface of the urethane foam 1, and the place indicated by 3 in Fig. 1 is sewn with a cotton thread to form the sewn portion 3.
  • the sample is heated using a burner 4 for 2 minutes at a distance of 5 cm from the sample.
  • Power Torch RZ-730 manufactured by Shinfuji Burner co., ltd. was used.
  • the temperature of the flame is adjusted to 1000 degrees using a thermocouple.
  • a case in which the fire is self-extinguished after the flame of the burner is extinguished and the urethane foam remains is graded B, and a case in which the fire is self-extinguished and the weight reduction rate of urethane foam is 5% by mass or less is graded A.
  • TORCON registered trademark
  • product number S371 manufactured by TORAY INDUSTRIES, INC.
  • This PPS fiber has a LOI value of 34, a melting point of 284°C, and a number of crimp of 11 crimps/2.54 cm.
  • the ratio of sulfur atoms in the fiber was 26.2% by mass.
  • a 1.7 dtex flame resistant fiber PYRON (manufactured by Zoltek companies, Inc.) cut into 51 mm was used.
  • the high-temperature shrinkage rate of PYRON was 1.6%.
  • PYRON was heated by a method conforming to JIS K 7193 (2010), ignition was not observed even at 1000°C, and the ignition temperature thereof was 1000°C or more.
  • the thermal conductivity was 0.042 W/m ⁇ K.
  • the number of crimp is 10 crimps/2.54 cm.
  • PET Polyethylene terephthalate
  • PET fiber As a drawn PET fiber, "TETORON” (registered trademark) (manufactured by TORAY INDUSTRIES, INC.) having a single fiber fineness of 2.2 dtex (diameter: 14 ⁇ m) and a cut length of 51 mm was used.
  • This PET fiber has an LOI value of 22 and a melting point of 267°C. The number of crimp is 17 crimps/2.54 cm. A sulfur atom was not detected in the fiber.
