Embodiment 1

[0155] As the coating material, the composition shown in Table 1 is composed of ethylene (Et) / tetrafluoroethylene (4F) / hexafluoropropylene (6F) / monomer A (CH 2 =CF(CF 2 ) 3 H) The copolymer (refractive index: 1.368) is supplied to the composite spinning machine. Furthermore, the PMMA ((refractive index 1.492) produced by continuous bulk polymerization is supplied to the composite spinning machine as the core material, and the core material and the cladding material are subjected to core-sheath composite melt spinning at a temperature of 235 ° C to obtain a fiber diameter 1000μm (core diameter 980μm, cladding thickness 10.0μm) plastic optical fiber.

[0156] Furthermore, a coating material in which 4% by weight of carbon black was added to polypropylene resin (manufactured by Sun Aroma; PMB60W) was coated with a cross head cable (cross headcable) coating method device using a cross head die set at a temperature of 180°C. On the above-mentioned plastic optical fiber, a plasti...

Embodiment 2～5

[0159] A plastic optical fiber cord was obtained in the same manner as in Example 1 except that the first covering material was changed to that shown in Table 1. Using these plastic optical fiber cords, the evaluation was carried out in the same manner as in Example 1, and the results are shown in Table 4.

Embodiment 6

[0161]A plastic optical fiber cord was obtained in the same manner as in Example 5, except that the covering material was changed to polypropylene elastomer (Surlink 4155, manufactured by Toyobo Co., Ltd.). Evaluation was performed in the same manner as in Example 1 using these plastic optical fiber cords, and the results are shown in Table 3.

Abstract

Disclosed are: a plastic optical fiber comprising a core and a clad composed of at least one layer, wherein the clad comprises a copolymer comprising, as a copolymer components, 10 to 35% by weight of ethylene, 45 to 69% by weight of tetrafluoroethylene, 20 to 45% by weight of hexafluoropropylene, and 0.01 to 10% by weight of a specific fluorovinyl compound; and a plastic optical fiber code comprising the plastic optical fiber. The plastic optical fiber and the plastic optical fiber code have such a level of heat resistance that they can withstand the use at an actual use temperature of 105°C. The plastic optical fiber and the plastic optical fiber code have a good balance among wet heat resistance, bending loss, flexibility and other properties and also has excellent pistoning properties, and therefore are suitable for automotive interior wiring and house wiring.

Description

Technical field [0001] The invention involves plastic fiber and plastic fiber soft lines.The present invention specially involves plastic fiber and plastic fiber soft lines that can withstand heat resistance, indoor wiring and internal car wiring under the actual use temperature of 105 ° C. Background technique [0002] Plastic fiber is better than glass -based optical fiber in terms of processing, operating, and manufacturing costs, so it is suitable for short -distance photocolochor transmission, photoelectric sensor and optical waveguide. [0003] Recently, as an intelligent credit line in the automotive internal intelligence, the plastic fiber fiber soft line covering nylon (polyamide) such as nylon (polyamide) on plastic optical fibers is used. [0004] Plastic fiber soft lines, when used in indoor wiring and internal communication wiring, often bent in a narrow space in a high temperature and humid environment, so heat resistance, humidity and heat, resistance to resistance...
